Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrode terminals are connected in series during battery module assembly, then electrical connection is achieved, but misalignment and polarity errors occur leading to abnormalities
Solution Approach 1:
The patent applies color-coded identification units (positive and negative identification units with different colors) on electrode terminals to enable quick visual distinction between positive and negative terminals. This allows assembly workers to rapidly identify correct polarity connections without time-consuming checks, thereby maintaining high assembly efficiency while preventing misalignment and polarity errors that compromise reliability.
2Reliability
If lengthy checks are performed to verify electrode terminal polarity, then misalignment errors are detected, but process time increases and productivity deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-marking electrode terminals with distinct color-coded identification units before assembly. This preliminary visual coding allows workers to instantly verify polarity during assembly without performing lengthy post-assembly checks. The identification units are applied in advance to batteries, enabling error prevention rather than detection, thus maintaining reliability while minimizing time loss.
3Reliability
If identification units with distinct colors or patterns are added to electrode terminals, then misalignment is prevented, but device complexity increases
Solution Approach 1:
The patent uses simple color-coded identification units (positive and negative identification units with different colors or patterns) that are applied to electrode terminals. These identification units provide clear visual distinction to prevent misalignment and improve reliability. The solution adds minimal structural complexity by using surface markings rather than complex mechanical or electronic identification systems.
