Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a conventional cooling unit with blowing fans is used to cool battery cells, then heat emission is achieved, but temperature differences occur among battery cells due to non-uniform cooling
Solution Approach 1:
The cooling unit is segmented into multiple blowing fans arranged in a matrix pattern, with each fan responsible for cooling specific battery cells in its vicinity. This segmentation ensures that cooling is distributed uniformly across all battery cells, eliminating temperature differences that occur with conventional single-unit cooling systems.
2Reliability
If battery cells are cooled non-uniformly, then cooling is achieved, but capacity deviation occurs making defect detection difficult
Solution Approach 1:
The cooling system is divided into multiple independent blowing fan units, each targeting specific battery cells. This ensures uniform temperature distribution across all cells, which is critical for accurate capacity measurement and defect detection during charge/discharge operations.
Solution Approach 2:
Each blowing fan provides localized cooling tailored to the specific thermal conditions of adjacent battery cells. This local quality approach ensures that each cell receives appropriate cooling attention, maintaining uniform temperature and enabling reliable defect detection through capacity measurement.
3Temperature
If multiple blowing fans are arranged in a matrix, then uniform cooling is achieved, but device complexity increases
Solution Approach 1:
Each blowing fan unit serves multiple functions: it cools multiple battery cells simultaneously, provides modular scalability, and maintains structural simplicity. The matrix arrangement allows the same fan design to be replicated across different positions, achieving uniform cooling without proportionally increasing overall system complexity.
