Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed configuration voltage measurement system is used, then the wiring structure is simple, but it cannot accommodate varying cell module configurations
Solution Approach 1:
The voltage measurement circuit board is designed with multiple connection ports and branch wires that can accommodate different cell module configurations. The circuit board can measure voltages for cell modules with varying numbers of series-connected cells by utilizing the branch wires and multiple connection ports, making a single circuit board design universal for multiple configurations without requiring complex external wiring adjustments.
Solution Approach 2:
The voltage measurement system is segmented into multiple independent voltage measuring units, each capable of measuring voltages across different ranges of series-connected cells. This segmentation allows the system to handle varying cell configurations by activating appropriate measuring units and connection ports, reducing the complexity of wiring by dividing the measurement function into modular segments.
2Adaptability or versatility
If external wire connections are used for different cell configurations, then the system is flexible, but the risk of wire breaks increases
Solution Approach 1:
Multiple voltage measurement functions are merged into a single integrated circuit board design. The branch wires and connection ports are built into the circuit board structure, combining the functions of multiple measurement configurations into one reliable integrated system. This eliminates the need for separate external wire connections for different cell configurations, thereby improving reliability while maintaining flexibility.
Solution Approach 2:
The circuit board serves as an intermediary between the cell modules and the measurement system. Instead of directly connecting external wires to different cell configurations, the circuit board provides a stable intermediate interface with built-in branch wires and connection ports that handle the adaptability requirements, protecting against wire breaks while maintaining connection flexibility.
3Adaptability or versatility
If a simplified circuit board design is used, then the manufacturing cost is low, but it cannot handle various cell module types
Solution Approach 1:
The circuit board incorporates dynamic connection capabilities through branch wires and multiple connection ports that can be configured for different cell module types. This dynamic design allows the same circuit board to adapt to various measurement requirements without requiring multiple specialized designs, balancing versatility with manufacturing efficiency by using a standardized base design with configurable connection options.
