Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large number of different cables are used to support various battery module types, then the adaptability of the maintenance system is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The patent implements a universal cable system where each cable is equipped with identification elements (RFID tags, barcodes, or other machine-readable identifiers) that enable a single cable type to be used with multiple battery module types. The control unit reads these identification elements to automatically determine compatibility and guide the maintenance operation, eliminating the need for operators to manually select from multiple specialized cable types.
Solution Approach 2:
The patent introduces a control unit as an intermediary between the cable and the battery module. This control unit contains a library of correspondence data that maps cable identification elements to compatible battery module types. The control unit automatically processes the identification information and determines compatibility, replacing the need for complex manual matching procedures and reducing the number of specialized cables required.
2Adaptability or versatility
If a large number of different cables are used to support various battery module types, then the adaptability of the maintenance system is improved, but the ease of operation deteriorates due to operator confusion and time waste
Solution Approach 1:
The patent implements an automated feedback system where the control unit reads the identification element on the cable, automatically queries the library of correspondence data, and provides immediate feedback to the operator about compatibility. The system displays clear guidance indicating whether the selected cable is appropriate for the specific battery module type, eliminating operator confusion and preventing incorrect connections.
Solution Approach 2:
The system enables self-service operation by automatically performing the cable selection and compatibility verification process. The control unit autonomously reads the cable identification, determines compatibility with the battery module, and guides the operator through the maintenance procedure without requiring manual reference to complex cable selection charts or procedures.
3Device complexity
If manual cable selection is used, then the device complexity is reduced, but the productivity and measurement precision deteriorate due to time consumption and potential errors
Solution Approach 1:
The patent replaces manual mechanical cable selection with an automated electronic identification and verification system. Machine-readable identification elements (RFID tags, barcodes) on the cables are read by the control unit, which automatically queries the library of correspondence data and determines compatibility. This electronic substitution eliminates manual searching and selection, significantly improving maintenance productivity while keeping the overall system structure relatively simple.
4Device complexity
If manual cable selection is used, then the device complexity is reduced, but the loss of time increases due to operator searching and verification
Solution Approach 1:
The patent implements preliminary action by pre-storing comprehensive correspondence data in the control unit's library before maintenance operations begin. The library contains pre-established relationships between cable identification elements and compatible battery module types. During actual maintenance, the system only needs to read the identification element and query the pre-prepared library, dramatically reducing selection and verification time without requiring complex real-time analysis.
