Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual or mechanical means are used to remove protective films from battery electrodes, then the protective film can be removed, but the testing process efficiency is reduced and time is lost
Solution Approach 1:
The patent combines the protective film scraping function and the electrical measurement function into a single integrated testing device. The conducting member serves dual purposes: it mechanically scrapes the protective film off the battery electrode while simultaneously establishing electrical contact for voltage and current measurements. This merging of functions eliminates the need for separate film removal and measurement steps, thereby improving testing efficiency without compromising measurement precision.
Solution Approach 2:
The testing device performs the protective film scraping action immediately before or during the initial contact with the battery electrode, preparing the surface for accurate measurement in advance. By scraping the film off first and then establishing electrical contact in a single continuous operation, the device ensures that measurement is performed on the exposed electrode surface without requiring separate preparation steps.
2Reliability
If a protective film is formed on battery electrodes, then electrode oxidation or damage is prevented, but direct contact with electrodes for testing cannot be achieved
Solution Approach 1:
The conducting member is designed with flexible bent portions that allow it to dynamically adapt to the battery electrode surface. The first and second bent portions enable the conducting member to flex and conform to the curved or irregular surface of the battery, ensuring reliable electrical contact after the protective film is scraped off. This dynamic flexibility compensates for surface variations and maintains stable contact during testing.
Solution Approach 2:
The conducting member features localized scraping structures at specific contact points that are designed to scrape the protective film off the battery electrode surface. These localized scraping portions are positioned to make direct contact with the electrode, allowing film removal and electrical contact to occur at the same location, thereby solving the contradiction between protection and accessibility.
3Adaptability or versatility
If the conducting member has bent portions for flexibility, then contact with battery surface is improved, but the structure becomes more complex
Solution Approach 1:
The conducting member incorporates first and second bent portions with curved geometries that match the typical curvature of battery surfaces. These bent portions are designed with smooth arcs rather than sharp angles, allowing the conducting member to conform to the rounded surfaces of battery electrodes. The curved structure provides adaptability to different battery shapes while maintaining manufacturing simplicity through standard bending processes.

Function Achieved in This Case
The device improves testing efficiency and accuracy by enabling direct contact with the battery electrodes, eliminating the need for manual film removal and enhancing the measurement of battery performance.
Implementation Method 1
The second bent portion has first scraping structure, and the first scraping structure protrudes or depresses from the upper surface of the conducting member
