Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated control board and cable are prepared for each component, then the component can be controlled reliably, but the number of control boards and cables increases, resulting in increased management costs and complexity
Solution Approach 1:
The control board is designed with a reconfigurable circuit configuration that allows it to adapt to different component types. The control unit reads component information from the connected component via the cable, determines the appropriate control program and wiring data, and configures its circuit accordingly. This enables a single control board to replace multiple dedicated control boards, reducing the number of control boards and cables needed while maintaining reliable control for each component type
Solution Approach 2:
The control board employs dynamic reconfiguration of its circuit configuration based on the connected component's characteristics. The control unit dynamically loads and executes different control programs corresponding to different component types, and dynamically adjusts the circuit wiring data to match the component's pin arrangement. This dynamic adaptability allows the control board to maintain reliable control while reducing system complexity
2Adaptability or versatility
If multiple dedicated control boards are used for different components, then each component receives appropriate control, but the management costs and complexity increase
Solution Approach 1:
The control board stores multiple control programs in its storage unit, each corresponding to a different component type. The control unit selects and loads the appropriate control program based on component information received via the cable, enabling the same control board to control various component types (light sensors, temperature sensors, actuators, etc.). This universality reduces management complexity by eliminating the need to manage multiple dedicated control boards for different components
3Reliability
If dedicated cables adjusted for each component are used, then proper connection is ensured, but the number of cables increases, increasing management costs
Solution Approach 1:
The system uses a universal cable with a standardized connector that can connect to different component types. The control board reads component information through this universal cable, identifies the component type, and automatically configures the appropriate wiring data and control program. This eliminates the need for multiple dedicated cables adjusted for each component type, reducing the quantity of cables required while maintaining reliable connections
