Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a traditional motor train underframe machining tool is used, then the machining function is complete, but the structure is large in volume and inconvenient for transportation and movement
Solution Approach 1:
The machining tool is divided into multiple independent modules including positioning device, pressing device, and intermediate supporting structures. Each module can be independently adjusted and reconfigured, reducing the overall volume when not in use while maintaining complete machining functionality when assembled.
Solution Approach 2:
The tool employs adjustable and movable components including sliding supporting frames, adjustable intermediate supporting structures, and reconfigurable positioning devices. These dynamic elements allow the tool to adapt its configuration for different machining tasks and reduce to compact form for transportation.
2Adaptability or versatility
If a traditional motor train underframe machining tool is used, then the basic machining function is provided, but the adjustability is poor and cannot meet the requirements of auxiliary machining for different types of underframes
Solution Approach 1:
The positioning and pressing device is designed with universal components that can accommodate multiple types of motor train underframes. The adjustable intermediate supporting structures and reconfigurable positioning devices enable the same tool to perform auxiliary machining on different underframe types without requiring completely different tooling.
Solution Approach 2:
The tool allows adjustment of key parameters including the position of supporting frames, the configuration of intermediate supporting structures, and the positioning device settings. These parameter changes enable adaptation to different underframe dimensions and geometries while maintaining a relatively simple base structure.
