Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery testing apparatuses are cumbersome and difficult to assemble or disassemble due to their complex structure, making them inconvenient to use for testing electrochemical properties of batteries like lithium-ion and air batteries.
Innovation Solution
A battery testing apparatus with a modular design comprising a substrate, a body with a bottom, central body, and cover, featuring specific hole configurations and insulation elements, allowing for easy assembly and disassembly, and utilizing a three-electrode method for testing electrochemical performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional battery testing apparatus is designed with complete testing functions, then the testing capability is improved, but the device complexity and size increase
Solution Approach 1:
The battery testing apparatus is divided into a battery chamber assembly and a control chamber assembly that can be separated. The battery chamber contains the electrochemical cell and electrodes, while the control chamber houses the testing controls. This segmentation allows the testing function to be maintained while reducing overall device complexity and enabling easier assembly and disassembly.
2Reliability
If a conventional battery testing apparatus includes all necessary components, then the testing function is complete, but the apparatus becomes larger and thicker
Solution Approach 1:
The electrodes are inserted through the battery chamber wall into the electrochemical cell, and the battery chamber assembly nests within or alongside the control chamber assembly. This nested arrangement allows multiple functional components to occupy overlapping or adjacent spaces, reducing the overall volume of the apparatus while maintaining complete testing functionality.
3Reliability
If a conventional battery testing apparatus has many elements, then the testing capability is enhanced, but the apparatus becomes harder to assemble or disassemble
Solution Approach 1:
The apparatus is segmented into modular assemblies (battery chamber and control chamber) that can be independently manufactured and then easily assembled together. The battery chamber assembly can be disassembled from the control chamber assembly, making maintenance, repair, and storage convenient while preserving complete testing capability.
