Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a compact drive mechanism is used, then the device size is reduced, but the reliability of power transfer and protection from foreign objects may be compromised
Solution Approach 1:
The drive mechanism is divided into separate functional components: a conductive base for power transfer, an insulating base for protection, and a motor/gear reducer assembly. This segmentation allows each component to be optimized for its specific function while maintaining overall compactness and reliability.
Solution Approach 2:
An insulating base is introduced as an intermediary component between the conductive base and the enclosure. This insulating base prevents foreign objects from causing short circuits while allowing the compact design to maintain reliable power transfer through the conductive base.
2Duration of action of stationary object
If a robust drive mechanism is used, then the lifespan is extended, but the device complexity and cost increase
Solution Approach 1:
The design changes the material parameters of the base components - using a conductive material for the base that transfers power, and an insulating material for the surrounding structure. This parameter change allows the same structural elements to serve multiple functions (structural support + electrical function), reducing overall complexity while extending lifespan through material selection.
3Volume of moving object
If a compact drive mechanism is used, then the device size is reduced, but the cost effectiveness may be compromised
Solution Approach 1:
The conductive base serves multiple functions simultaneously: it provides structural support for the drive components, acts as an electrical conductor for power transfer to the torch cable, and forms part of the mounting structure for the motor and gear reducer. This multi-functionality reduces the number of separate parts needed, simplifying manufacturing and reducing cost while maintaining compact dimensions.
