Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the port frame is separately processed and then assembled to the middle frame body, then the port frame can implement diverse functions, but the connection error between the port frame and middle frame body becomes large
Solution Approach 1:
The port frame is divided into multiple functional modules including a frame body, a first connection component for electrical connection, and a second connection component for mechanical connection. This segmentation allows each component to be processed and assembled separately while maintaining connection precision through dedicated connection interfaces and positioning structures.
2Adaptability or versatility
If the port frame is separately processed and assembled, then functional diversity is achieved, but subsequent processing and alignment are affected
Solution Approach 1:
Positioning structures are pre-formed on both the port frame and middle frame body before assembly. These positioning structures include positioning holes and positioning protrusions that guide the alignment and connection processes, making subsequent assembly easier and more precise.
3Weight of moving object
If a slim and lightweight design is implemented, then the device becomes thinner and lighter, but the structural strength and risk of cracking increase
Solution Approach 1:
The connection components utilize composite material structures that combine different materials with complementary properties. The first connection component provides electrical conductivity while the second connection component provides mechanical strength, achieving both lightweight design and structural durability.
4Reliability
If the contact area between port frame and middle frame body is increased, then electrical conductivity is improved, but the structural complexity increases
Solution Approach 1:
The first connection component and second connection component are integrated into a unified connection structure. The first connection component makes electrical contact while the second connection component provides mechanical attachment, combining both functions in a single integrated assembly that reduces overall structural complexity.
