Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If branch wires are added to accommodate different cell module configurations, then versatility is improved, but the complexity of wiring increases and the risk of wire breaks increases
Solution Approach 1:
The voltage measurement circuit is divided into multiple independent voltage measuring units, each capable of measuring voltages for different cell module configurations. Each unit has its own set of connection ports and measurement circuits, allowing the system to handle various configurations without requiring complex branch wiring.
Solution Approach 2:
Each voltage measuring unit is designed to be universal, capable of measuring voltages across different cell module configurations through its multiple connection ports. The circuit board can accommodate various cell arrangements (e.g., series-parallel combinations) without requiring physical reconfiguration or additional branch wires.
2Adaptability or versatility
If branch wires are added to accommodate different cell module configurations, then versatility is improved, but reliability deteriorates due to increased wire break risk
Solution Approach 1:
By segmenting the measurement function into multiple independent units integrated on the circuit board, the design eliminates the need for external branch wires. Each voltage measuring unit is self-contained with its own connection ports and measurement circuitry, removing the reliability risk associated with additional wire connections.
Solution Approach 2:
The circuit board itself acts as an intermediary, providing integrated connection ports and measurement circuits that eliminate the need for external branch wires. The board's internal circuitry mediates between the cell terminals and the measurement system, ensuring reliable connections without requiring additional wire branches.
3Adaptability or versatility
If multiple voltage measuring units with additional connection ports are provided, then versatility is improved, but device complexity increases
Solution Approach 1:
Multiple voltage measuring units are merged and integrated onto a single circuit board, sharing common structural support and electrical ground references. The units are combined in a modular fashion, where each unit contains essential measurement functionality but benefits from the integrated board design, reducing overall complexity compared to separate independent units.
Solution Approach 2:
The circuit board is designed as a universal platform that can measure voltages for various cell module configurations simultaneously or independently. Each voltage measuring unit provides multi-functionality, and their integration on the same board creates a versatile system that handles different configurations without proportionally increasing complexity.
