DETAILED DESCRIPTION

(7) The following detailed description refers to the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the following description to refer to the same or similar elements. While embodiments of the claimed subject matter may be described, modifications, adaptations, and other implementations are possible. For example, substitutions, additions, or modifications may be made to the elements illustrated in the drawings, and the methods described herein may be modified by substituting, reordering, or adding stages to the disclosed methods. Accordingly, the following detailed description does not limit the claimed subject matter. Instead, the proper scope of the claimed subject matter is defined by the appended claims.

(8) The claimed embodiments offer an improvement over prior art systems by integrating a controlled pressure mechanism and a movable barrier within a single container to facilitate the efficient exchange of unused and used fluids. By employing a linear actuator, spring, or similar device, the container maintains a stable internal pressure that drives the movement of the barrier as fluid is extracted or introduced. This controlled pressure system allows for precise management of fluid volumes within the container, ensuring that the unused fluid is dispensed smoothly from the upper portion while simultaneously accommodating the influx of the used fluid from the bottom. The coordinated action of the barrier not only prevents spillage and cross-contamination but also optimizes the use of available space, as the barrier adjusts dynamically to the changing fluid volumes.

(9) The claimed embodiments also improve over prior art systems by offering a compact, space-saving solution through the integration of both fluid storage and separation functions within a single container. Unlike traditional setups that require multiple containers or external reservoirs for storing unused and used fluids separately, this claimed embodiments consolidate these processes, eliminating the need for additional space-consuming components. By housing both fluids within a single structure and employing a movable barrier to dynamically adjust fluid volumes, the embodiments significantly reduce the spatial footprint required for fluid exchange operations. This compact design not only simplifies installation and storage but also enhances portability, making it ideal for applications in constrained environments where space is at a premium. The efficiency gained through the single-container approach allows users to achieve the same fluid separation and storage results without the complexity and bulk of traditional multi-component systems, thereby maximizing operational space and enabling a more practical and versatile fluid management solution.

(10) Unlike prior art systems that rely on passive gravity-based movement, the claimed embodiments create a more active and reliable fluid exchange, minimizing the need for external handling or additional equipment. The single-container design reduces spatial requirements while providing a compact and efficient solution for applications where both access to clean fluid and collection of runoff are essential. The claimed embodiments are advantageous for tasks requiring repetitive or continuous fluid exchanges, as the pressure-regulated barrier adapts automatically, reducing the need for manual oversight. Furthermore, by isolating unused and used fluids within the container, the invention enhances fluid purity and quality, allowing the unused fluid to remain uncontaminated throughout the operation. Overall, the claimed embodiments address the limitations of prior art systems by offering a streamlined, efficient, and self-contained solution for fluid management and conservation. One of the possible applications of the claimed embodiments is zero impact camping, wherein campers attempt to have little to no impact on the surrounding area, which requires that the campers bring all of the fluid they intend to use, and pack out all of the expended fluid they intend to dispel.

(11) The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate various example embodiments. The claimed pressure regulated volume exchange container 100 will now be described with respect to FIGS. 1 through 4.

(12) FIG. 1 is a block diagram depicting components of a pressure regulated volume exchange container 100, according to an embodiment. In FIG. 1, the container 102 serves as the main structure for holding both the unused and used fluids within distinct regions or volumes, designated as the first volume 104 and the second volume 106, respectively. The first volume 104 is intended to store the unused fluid that will be dispensed or utilized. The second volume 106 receives and stores the used fluid after it has been drawn from the first volume, effectively isolating it within the container to prevent contamination of the unused fluid. Though FIG. 1 shows one volume on top of the other, this is for exemplary purposes only and the claimed embodiments support any arrangement of the two volumes.

(13) A movable barrier 130 is positioned within the container 102, separating the first volume 104 from the second volume 106. This barrier 130 is designed to adjust its position as the fluid volumes change, thereby maintaining a consistent division between the two fluids while allowing the container to accommodate varying amounts of each fluid. The movable barrier may be a flexible diaphragm configured to form a seal between the first volume portion and the second volume portion, preventing cross-contamination between the first and second fluids.

(14) The movement of this barrier is controlled by an actuator 120, which applies pressure or force to move the barrier in response to the extraction of the unused fluid or the introduction of the used fluid, as well as in response to other factors. The actuator may be a linear actuator, spring, or any mechanical device that is configured to move the barrier in the upwards and/or downwards directions. This actuator 120 is essential for ensuring that the first and second volumes remain isolated, and that the barrier can adjust dynamically based on fluid demands, as well as maintaining certain pressure requirements, among other things.

(15) Fluid entry and exit from the container are managed through several inlets and outlets equipped with valves. The first volume inlet 114 in the container allows for the introduction of the unused fluid into the first volume 104. The first volume inlet valve 114a regulates this inlet, opening or closing as needed to control the inflow of unused fluid. The first volume outlet 124 in the container provides an exit for the unused fluid when it is needed externally. The first volume outlet valve 124a controls this outlet, ensuring that fluid flow occurs only when required.

(16) The second volume inlet 116 in the container serves as the entry point for the used fluid into the second volume 106. The second volume inlet valve 116a regulates this inlet, enabling controlled entry of the used fluid and ensuring it remains separated from the unused fluid in the first volume. The second volume outlet 126 in the container allows for the discharge of the used fluid when necessary. The second volume outlet valve 126a manages this outlet, providing controlled exit for the used fluid and allowing for easy removal or disposal.

(17) In combination, the described components enable efficient management of both unused and used fluids within a single container, providing controlled separation and access through a dynamic, actuated barrier system. Each inlet and outlet, together with its respective valve, functions in concert with the movable barrier 130 and actuator 120 to ensure that the fluid volumes are handled precisely, enabling a compact and efficient solution for fluid exchange and storage.

(18) It should be noted that even though FIG. 1 discloses only one container, two volumes, one barrier, one actuator, two inlets, two outlet, and four valves, the different embodiments of the invention support any number of volumes, barriers, actuator, inlets, outlets and valves. For example, in one embodiment of the invention, two or more actuators can be used to apply pressure or force to move the barrier in response to the extraction of the unused fluid or the introduction of the used fluid, as well as in response to other factors

(19) FIG. 2A is a block diagram depicting components for data transfer of the pressure regulated volume exchange container 100, according to an embodiment. In FIG. 2A, the computing device 202 is shown as the central control unit, interfacing with various sensors and the actuator 120 to monitor and regulate fluid flow and pressure within the pressure regulated volume exchange container 100. The computing device 202 is connected to the actuator 120, enabling it to control the movement of the barrier (described in FIG. 1) within the container 102. By commanding the actuator 120, the computing device can adjust the barrier's position in response to changing fluid levels and pressure, ensuring that the unused and used fluids remain isolated while maintaining consistent separation within the container.

(20) The actuator 120 is configured to provide servo data to the computing device 202, delivering real-time feedback on its position, speed, and force exerted in moving the barrier within the container. This servo data allows the computing device to track the precise position of the barrier, ensuring proper pressure within the volumes and inlets/outlets, as well as accurate separation between the first and second volumes as fluids are introduced or extracted. By monitoring the actuator's position, speed and force output, the computing device can detect any resistance or irregularities in the movement of the barrier, which may indicate issues such as fluid imbalances or mechanical obstructions. This feedback loop enables the computing device to make real-time adjustments, optimizing actuator performance to maintain ideal fluid levels and pressures within the container and the inlets/outlets.

(21) A first volume pressure sensor 206 is positioned within the first volume 104 to detect and measure the pressure of the unused fluid. This sensor provides real-time data on the pressure within the first volume, enabling the computing device 202 to monitor the conditions of the unused fluid. If the pressure deviates from expected levels-indicating, for example, a change in fluid volume or a potential leakthe computing device 202 can adjust the actuator 120 to maintain optimal or desired conditions. Similarly, a second volume pressure sensor 216 is located within the second volume 106 to measure the pressure of the used fluid. The data from this sensor informs the computing device 202 about the conditions in the second volume, allowing it to detect any fluctuations that may necessitate adjustments to the actuator or the outlet valves.

(22) Additionally, FIG. 2A illustrates a series of pressure or flow sensors connected to various inlets and outlets, providing the computing device with comprehensive information on fluid movement throughout the system. A pressure or flow sensor 208 is associated with the first volume inlet 114, monitoring the inflow of unused fluid into the container. This sensor measures both the rate of flow and the pressure, allowing the computing device 202 to regulate the inflow in accordance with the needs of the system. Similarly, a pressure or flow sensor 210 is connected to the first volume outlet 124, measuring the outflow of unused fluid from the first volume. By monitoring this data, the computing device can manage the flow rate and ensure that fluid is dispensed efficiently and according to demand.

(23) The second volume inlet 116 is equipped with a pressure or flow sensor 212, which reads the inflow characteristics of the used fluid as it enters the container. This sensor provides the computing device with critical information on the used fluid entering the system, allowing the computing device to maintain the balance between unused and used fluid volumes. Lastly, a pressure or flow sensor 214 is connected to the second volume outlet 126, measuring the outflow of used fluid from the second volume. Data from this sensor allows the computing device to control the discharge of used fluid and maintain system equilibrium, preventing overflow or unintended discharge.

(24) Using the collective data from these sensors, the computing device 202 can execute precise control over the actuator 120 and the flow of fluids within the container. By continuously analyzing pressure and flow data, the computing device dynamically manages fluid exchange, barrier positioning, and valve operation to optimize the system's efficiency and reliability. This real-time, sensor-driven approach enables the container to adapt to varying fluid levels and pressures, ensuring that unused and used fluids are consistently separated and handled within the single-container system.

(25) FIG. 2B is a block diagram depicting components for controlling the pressure regulated volume exchange container 100, according to an embodiment. In FIG. 2B, the computing device 202 is depicted as a centralized control system that interfaces with the actuator 120 and the valves 114a, 124a, 116a, and 126a, coordinating the movement of fluids within the container in response to real-time data inputs. The computing device 202 controls the actuator 120, adjusting its position to move the barrier within the container as fluid levels change. Using the data collected from the pressure and flow sensors, the computing device can direct the actuator 120 to maintain the appropriate separation between the unused and used fluids, ensuring that the fluid volumes are dynamically balanced.

(26) Valve 114a is connected to the first volume inlet 114 and is responsible for controlling the flow of unused fluid into the container. The computing device 202 utilizes data on the current volume and pressure of the unused fluid to open or close valve 114a as needed, regulating the introduction of unused fluid based on system requirements. Valve 124a, associated with the first volume outlet 124, controls the outflow of unused fluid from the container. By monitoring pressure and flow data at the outlet, the computing device can operate valve 124a to manage the dispensing of unused fluid, ensuring that it flows only when necessary and at an optimal rate.

(27) Valve 116a is connected to the second volume inlet 116, which controls the entry of used fluid into the container. Based on data from the second volume pressure sensor and other system inputs, the computing device 202 operates valve 116a to allow used fluid to flow into the container at a controlled rate, adjusting as needed to maintain the separation of fluids and avoid overflow. Finally, valve 126a, connected to the second volume outlet 126, regulates the discharge of used fluid from the container. The computing device uses flow and pressure data to open or close valve 126a as necessary, allowing for the efficient removal of used fluid when required while maintaining pressure equilibrium within the system.

(28) By coordinating the operation of the actuator 120 and valves 114a, 124a, 116a, and 126a, the computing device 202 dynamically manages pressure, fluid exchange and separation within the container, adapting to changing conditions in real time to optimize system performance. The ability to precisely control each component ensures efficient fluid transfer, effective separation of unused and used fluids, and maintenance of stable pressures and fluid levels within the container.

(29) FIG. 3 is a flow chart depicting the general control flow of a process 300 undertaken by the pressure regulated volume exchange container 100, according to an embodiment. Process 300 begins with the initial step 302, wherein a position of a valve, such as valve 114a, is adjusted, which may be opened, closed, or set to a specific intermediate position. This valve adjustment controls the inflow or outflow of fluid, depending on the operational state of the container.

(30) Once the valve has been adjusted, in step 304 the computing device 202 proceeds to the data-reading phase, where it collects real-time information from the multiple sensors embedded within the system (see FIG. 2A). This includes pressure data from pressure sensors positioned in the first and second volumes, flow rates from flow sensors connected to the inlets and outlets, and servo data from the actuator. The computing device 202 processes this information to gain an accurate snapshot of current fluid levels, flow rates, and pressures within the container. This comprehensive data set provides insight into the fluid conditions in both the unused and used volumes, as well as the operational state of each component.

(31) Following data collection, the computing device 202 analyzes the sensor readings to determine if any adjustments are needed to maintain the predefined pressure within the first volume and stable fluid separation within the container. For example, if the pressure in the first volume deviates from the predefined threshold, the computing device will calculate the necessary adjustments to the actuator's position to bring the pressure back within the desired range. This analysis may also include assessing the actuator's force and speed, as derived from the servo data, to ensure that the actuator's movement aligns with the requirements for pressure regulation and volume balance.

(32) Based on this analysis, in step 306, the computing device 202 executes an adjustment to the actuator in the next step. The computing device sends a command to the actuator to move the barrier within the container in a precise manner. This movement is calibrated to account for the fluid volume change in the first and second volumes, with the goal of preserving the designated separation between unused and used fluids. The actuator adjustment is executed smoothly to prevent any abrupt shifts in pressure or fluid levels that could compromise the system's performance or fluid quality.

(33) In the final step 308, the computing device 202 makes any necessary adjustments to the valves connected to the fluid inlets and outlets. Using the previously analyzed sensor data, the computing device determines whether to further open, close, or modulate each valve to control fluid flow effectively. By adjusting the valves, the computing device ensures that fluid can enter or exit the container as needed without disrupting the internal pressure or the separation between the first and second volumes. Once these adjustments are complete, the computing device re-initiates the process, returning to step 302, continuously reading data and making real-time adjustments to maintain optimal system performance and fluid separation.
