Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compression apparatuses face challenges in effectively leading high-pressure cathode gas to a space between a compression unit and an end plate, leading to potential deformation and increased contact resistance between members due to inadequate gas flow channel configurations.
Innovation Solution
The compression apparatus integrates plates by surface joining to create specific gas flow channels, reducing the exposed area to high-pressure cathode gas and using SUS316L for acid-resistant and hydrogen-brittleness-resistant materials, with elastic bodies to inhibit deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a compression device is designed to accommodate different body types and sizes, then adaptability is improved, but device complexity increases due to requiring multiple pad sizes and positioning mechanisms
Solution Approach 1:
The compression pad is designed with flexible and adjustable components that can dynamically adapt to different body types. The pad includes adjustable straps, flexible materials, and positioning mechanisms that can be modified during use to accommodate various patient anatomies without requiring multiple fixed-size pads
Solution Approach 2:
The compression device is designed as a universal system that can serve multiple patient types and injury locations. The pad incorporates universal adjustment mechanisms, standardized interfaces, and modular components that allow a single device design to function across different body sizes and compression needs
2Reliability
If compression force is increased to improve therapeutic effect, then treatment effectiveness is improved, but patient comfort deteriorates due to excessive pressure
Solution Approach 1:
The compression system incorporates dynamic adjustment capabilities allowing compression force to be modified based on patient feedback and treatment progress. The device includes adjustable tensioning mechanisms, flexible materials that adapt to tissue response, and positioning systems that can be optimized to distribute pressure evenly, enabling effective compression without excessive localized pressure
Solution Approach 2:
The compression pad utilizes materials and mechanisms that allow compression parameters to be changed and optimized. The flexible materials can adjust their stiffness and compression characteristics, while the positioning mechanisms allow for parameter adjustments in strap tension, pad placement, and compression distribution to balance effectiveness and comfort

AI summary
A compression apparatus includes at least one compression unit including an electrolyte membrane, an anode provided on a first principal surface of the electrolyte membrane, a cathode provided on a second principal surface of the electrolyte membrane, an anode separator stacked on the anode, and a cathode separator stacked on the cathode, a voltage applier that applies a voltage between the anode and the cathode, an anode end plate provided on the anode separator located at a first end in a direction of stacking, a cathode end plate provided on the cathode separator located at a second end in the direction of stacking, and first and second plates provided between the cathode end plate and the cathode separator located at the second end. The compression apparatus causes, by using the voltage applier to apply a voltage, protons taken out from an anode fluid that is supplied to the anode to move to the cathode via the electrolyte membrane and produces compressed hydrogen. The first plate has formed therein a first space in which to store a cathode gas containing the compressed hydrogen. The second plate is provided with a first manifold through which the cathode gas flows and a first communicating path through which to lead, to the first space, the cathode gas having flowed in from the first manifold.
