Pressurized Fluid Reservoir Assembly With Shared Valve and Venting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressurized fluid storage systems for vehicles require multiple smaller tanks due to limited space, leading to bulkiness and excessive weight, particularly from separate solenoid valves, which hinder optimal space utilization and increase the overall weight of the system.
Innovation Solution
A modular storage and distribution system with integrated functional components and shared solenoid valve, optimized tank arrangement, and integrated venting mechanisms, using a single vent to atmosphere, and a load-bearing structure for connection and support, reducing the number of valves and enhancing space efficiency and weight reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple smaller tanks are installed to increase storage capacity in limited space, then storage capacity is improved, but the bulk of functional components prevents optimal space utilization and weight increases
Solution Approach 1:
The patent combines multiple tanks into a single integrated tank structure with multiple compartments, eliminating the need for separate functional components for each tank. This merging approach reduces the total number of solenoid valves and other components, thereby reducing system weight while maintaining the required storage capacity through the multi-compartment design
2Quantity of substance
If multiple smaller tanks are installed to increase storage capacity in limited space, then storage capacity is improved, but the bulk of functional components prevents optimal space utilization
Solution Approach 1:
The patent merges multiple tanks into a single integrated structure with multiple compartments, which consolidates the functional components into one location. This reduces the overall space footprint by eliminating the need for separate functional components distributed across multiple tank locations, while the multi-compartment design maintains the required storage capacity within the available space
3Area of stationary object
If a single large-capacity tank is used to maximize storage, then space utilization is improved, but the available space is not compatible with integration of a single large tank
Solution Approach 1:
The patent segments the tank into multiple compartments within a single integrated structure. This segmentation allows the tank to adapt to the available irregular space in the vehicle while maintaining a unified structure that shares common functional components, thereby achieving both optimal space utilization and high storage capacity
4Reliability
If separate solenoid valves are installed for each tank to enable independent control, then operational reliability is improved, but weight and space increase significantly
Solution Approach 1:
The patent merges the functional components into a single shared structure that serves multiple tank compartments. This allows independent control of each compartment while sharing common solenoid valves and other functional elements, thereby reducing the total weight and space required compared to having separate components for each tank
