Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional structures for battery analysis do not effectively suppress expansion and contraction of all-solid-state batteries during charging and discharging cycles, leading to capacity deterioration and resistance increase, and require complex assembly processes due to the need for airtightness and high pressure application.
Innovation Solution
A structure for battery analysis that includes a battery accommodation unit with a pressurizing mechanism and a pressure receiving unit, where the sample battery is pressurized between these units to secure a conductive path and suppress expansion, and a simple screwing operation is used to assemble and seal the device, ensuring airtightness and high-pressure application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional tightening structures using multiple nuts are used to ensure airtightness, then airtightness is improved, but device complexity increases and large pressure cannot be applied
Solution Approach 1:
The patent combines the airtight sealing function and the pressurization function into a single integrated structure. The pressing member integrates the sealing surface and the pressurization mechanism, eliminating the need for separate sealing components and multiple nuts, thereby reducing assembly complexity while maintaining both airtightness and pressurization capabilities
Solution Approach 2:
The pressing member serves multiple functions simultaneously: it provides airtight sealing through its sealing surface, applies pressurization force to the sample battery, and maintains structural integrity. This multi-functional design replaces the conventional multi-component sealing and pressurization system, reducing the number of parts and assembly steps
2Reliability
If conventional tightening structures using multiple nuts are used, then airtightness is improved, but the pressing force is insufficient to secure conductive path
Solution Approach 1:
The patent merges the sealing function and pressurization function into one integrated pressing member structure. This allows the same component to provide both airtight sealing and sufficient pressing force to secure the conductive path, eliminating the trade-off between sealing strength and pressing force that exists in conventional multi-nut designs
3Reliability
If pressurizing mechanism protrudes components from window portion, then airtightness is improved, but manufacturing precision requirements increase
Solution Approach 1:
The pressing member is designed with a pre-configured pressing surface that is positioned to contact the sample battery before final tightening. This preliminary positioning ensures that the pressing force is applied at the correct location to secure the conductive path, while the integrated design maintains airtightness without requiring high-precision protrusion of components from the window portion
