Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple structure is used in the emergency starting clamp, then the device complexity is reduced, but the response time increases and safety decreases
Solution Approach 1:
The control circuit is divided into multiple functional modules: voltage detection module, temperature detection module, control module, and execution module. Each module independently performs its specific function, enabling fast response while maintaining modular simplicity in the overall structure.
Solution Approach 2:
The voltage detection module and temperature detection module continuously monitor battery parameters before the starting operation is initiated. This preliminary detection ensures that when the starting signal is received, the system can immediately determine whether conditions are suitable for starting, achieving fast response without complex real-time computation.
2Device complexity
If a simple structure is used in the emergency starting clamp, then the device complexity is reduced, but the safety features decrease
Solution Approach 1:
The control circuit is segmented into specialized detection and control modules. The voltage detection module monitors battery voltage, the temperature detection module monitors battery temperature, and the control module processes signals and controls the relay. This segmentation allows each module to be optimized for its specific function, improving safety while keeping the overall structure simple and modular.
Solution Approach 2:
The system implements feedback through continuous voltage detection and temperature detection. The detection modules constantly monitor battery parameters and provide feedback to the control module, which adjusts the starting control accordingly. This feedback mechanism ensures safe operation by preventing starting under unsuitable conditions without requiring complex control logic.
3Reliability
If multiple protection modules are added to improve safety, then the reliability increases, but the device complexity increases
Solution Approach 1:
The voltage detection module, temperature detection module, and control module are integrated into a single control circuit system. Multiple protection functions (voltage protection, temperature protection, over-current protection) are combined within this unified circuit, achieving high reliability while avoiding the complexity of separate independent protection systems.
Solution Approach 2:
The control module serves multiple functions: it receives starting signals, processes detection signals from voltage and temperature modules, determines suitability for starting, and controls the relay. This multi-functionality reduces the need for separate dedicated circuits for each function, maintaining simplicity while providing comprehensive protection.
