Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid mounting assemblies are used to connect aircraft components, then structural strength and stability are improved, but internal stress and wear increase leading to premature failure
Solution Approach 1:
The mounting assembly incorporates bushings that change the mechanical parameters of the connection from rigid to semi-flexible, allowing controlled movement and stress distribution while maintaining overall structural integrity
Solution Approach 2:
Bushings are introduced as intermediary elements between the fastener and the aircraft components, serving as a mediator that reduces direct stress transmission and wear between rigid components
2Stability of the object's composition
If fixed mounting assemblies are used to ensure precise component positioning, then positional stability is improved, but stress concentration and wear increase
Solution Approach 1:
The mounting assembly transitions from a completely fixed configuration to a dynamic system where bushings allow controlled movement and adjustment, enabling the structure to adapt to thermal expansion and vibration while maintaining positional stability
3Device complexity
If traditional mounting assemblies without movement control are used, then device complexity is reduced, but internal stress and wear lead to premature failure
Solution Approach 1:
The mounting assembly is segmented into distinct functional elements (fastener, bushings, washers) where each component serves a specific purpose, allowing the system to manage stress and movement while maintaining relatively simple individual parts
