Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the insulating structure is disposed on the first wall without limiting structures, then the device complexity is reduced, but the manufacturing precision deteriorates due to misalignment between the insulating structure and the first wall
Solution Approach 1:
The limiting structure is divided into two segments: a first limiting structure on the first wall and a corresponding second limiting structure on the insulating structure. This segmentation allows each component to be independently manufactured and positioned, improving alignment precision without significantly increasing overall device complexity.
Solution Approach 2:
The limiting structures act as intermediary positioning elements between the first wall and the insulating structure. These intermediaries provide precise alignment during assembly, ensuring manufacturing precision while maintaining relatively simple structural designs for both the wall and insulating structure.
2Weight of stationary object
If the insulating structure is made thin to reduce weight, then the weight of the stationary object is reduced, but the reliability deteriorates due to insufficient insulation performance
Solution Approach 1:
The limiting structure is divided into two segments: a first limiting structure on the first wall and a corresponding second limiting structure on the insulating structure. This segmentation allows each component to be independently manufactured and positioned, improving alignment precision without significantly increasing overall device complexity.
Solution Approach 2:
The limiting structures act as intermediary positioning elements between the first wall and the insulating structure. These intermediaries provide precise alignment during assembly, ensuring manufacturing precision while maintaining relatively simple structural designs for both the wall and insulating structure.
