Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connection and torque transfer apparatus with electrically insulated torque input and output ends is designed, then electrical insulation performance is improved, but device complexity increases
Solution Approach 1:
The apparatus is divided into three separate components: a torque input component, an intermediate body component made of insulating material, and a torque output component. This segmentation allows electrical insulation while maintaining functional integrity, as each component can be optimized independently for its specific role in torque transmission.
Solution Approach 2:
An intermediate body component made of insulating material is introduced between the torque input component and torque output component. This intermediary element provides the necessary electrical insulation while still allowing mechanical torque transfer through gear engagement, solving the contradiction between insulation and functionality.
2Reliability
If a connection and torque transfer apparatus with electrically insulated torque input and output ends is designed, then safety for simultaneous screwing at multiple potential points is improved, but manufacturing complexity increases
Solution Approach 1:
By segmenting the apparatus into modular components (input component, intermediate insulating body, output component), each part can be manufactured separately using appropriate processes and then assembled. This reduces manufacturing complexity compared to creating a single complex integrated part with both metallic and insulating properties.
Solution Approach 2:
The intermediate body component is made of insulating material while the input and output components are made of metallic materials. This composite material approach allows each component to be manufactured from its optimal material, simplifying the overall manufacturing process while achieving the required electrical insulation and mechanical strength.
