Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple riveted units are used to form a bending structure, then the catheter can swing laterally, but the manufacturing process becomes troublesome and difficult
Solution Approach 1:
The patent combines multiple separate riveted units into a single integrated bending structure consisting of elastic spring rings and a fixed seat. This merging eliminates the need for multiple riveting operations while maintaining the catheter's swinging capability, directly resolving the contradiction between operational flexibility and manufacturing complexity.
Solution Approach 2:
The patent uses elastic spring rings as flexible components to replace rigid riveted units. These elastic rings provide the necessary flexibility for catheter swinging while being simpler to manufacture as a single piece, thus improving ease of manufacture without sacrificing operational capability.
2Adaptability or versatility
If multiple units are combined for each catheter, then the bending function is achieved, but the manufacturing convenience is reduced
Solution Approach 1:
The patent merges multiple discrete units into a single integrated bending structure that includes elastic spring rings and a fixed seat. This single structure provides the complete bending function without requiring assembly of multiple separate components, significantly improving manufacturing convenience while maintaining full adaptability.
3Ease of operation
If conventional hinged units are buckled together, then the pipe can swing, but the machining cost is high
Solution Approach 1:
The patent replaces conventional hinged units with elastic spring rings that provide swinging capability through their inherent elasticity. This eliminates the need for complex hinged mechanisms and reduces machining costs while maintaining the pipe's ability to swing effectively.
Solution Approach 2:
The elastic spring rings utilize their own elastic properties to enable swinging motion without requiring additional hinges or complex mechanical joints. This self-service approach reduces the number of components and lowers machining costs while preserving full operational capability.
