Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual control is used to connect battery simulation device to BMS, then device complexity is reduced, but productivity decreases and time consumption increases
Solution Approach 1:
A relay box is introduced as an intermediary device between the battery simulation device and BMS. The relay box contains multiple relay modules that automatically establish or disconnect signal paths based on control signals, eliminating the need for manual connection operations while maintaining system simplicity.
Solution Approach 2:
The relay modules are designed to automatically respond to control signals from the computer device, enabling the system to self-manage connections without human intervention. The relay boxes autonomously configure signal paths based on testing requirements, improving productivity while keeping the control mechanism straightforward.
2Adaptability or versatility
If multiple relay modules are used to control signal paths, then adaptability increases, but device complexity increases
Solution Approach 1:
The relay box is divided into multiple independent relay modules, each capable of controlling a separate signal path. This segmentation allows flexible configuration of different connection scenarios while keeping each individual module relatively simple in structure.
Solution Approach 2:
Each relay module is designed with universal functionality to handle different signal paths and connection scenarios. The modules can be configured through standardized control signals from the computer device, enabling adaptable signal path management without requiring complex dedicated circuits for each scenario.
