Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional rigid connections are used between bush and ring, then connection strength is improved, but assembly force requirement increases and assembly complexity worsens
Solution Approach 1:
The bush is designed with a deformable section that changes its physical state during assembly. The bush material or structure allows temporary deformation under assembly force, enabling insertion, then restores its original shape to create a strong form-fit connection. This parameter change resolves the contradiction by allowing easy assembly through controlled deformation while maintaining strong connection after assembly.
Solution Approach 2:
The connection between bush and ring transitions from a static rigid structure to a dynamic system where the bush can deform and restore. The deformable bush acts as a spring element that absorbs assembly energy and provides continuous elastic restoring force, enabling simple assembly while maintaining strong operational connection.
2Reliability
If high assembly forces are used to ensure secure connection, then connection reliability is improved, but disassembly difficulty increases and maintenance time worsens
Solution Approach 1:
The deformable bush allows the connection to be established through temporary parameter change (deformation during assembly) that automatically restores after assembly. This creates a reliable form-fit connection during operation while allowing controlled reversal during disassembly, resolving the contradiction between reliable connection and easy maintenance.
3Ease of operation
If complex assembly mechanisms are used to simplify assembly, then assembly ease is improved, but device complexity increases and manufacturing cost worsens
Solution Approach 1:
The invention extracts the complexity from the assembly mechanism and transfers it to the bush material properties. Instead of using complex external assembly tools or mechanisms, the solution relies on the inherent deformable characteristics of the bush itself, simplifying the overall assembly system while maintaining ease of operation.
Solution Approach 2:
The deformable bush performs the assembly function through its own material properties without requiring complex external mechanisms. The bush's elastic deformation and restoration capabilities enable self-contained assembly and disassembly operations, reducing overall device complexity while improving ease of operation.

Function Achieved in This Case
The solution enables quick and cost-effective manufacturing, easy maintenance, and reduced downtime by allowing simple assembly and disassembly of the coupling, while maintaining mechanical stability and reliability.
Implementation Method 1
In the end area, the bush has a shape that is able to be deformed by an assembly force in a restorable manner, i.e. essentially elastically, and in this way a form fit with the ring is created
