Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conductive wire is inserted through the axial central part of the curved part, then the conductive function is achieved, but the diameter of the bending structure cannot be reduced
Solution Approach 1:
The patent merges the structural function (coil part) and conductive function into a single integrated component. The coil part itself is made conductive, eliminating the need for separate conductive wires. This is achieved by using conductive material for the coil or applying conductive coating, thereby combining mechanical support and electrical conduction in one element.
Solution Approach 2:
The patent extracts the conductive function from the separate conductive wire and integrates it directly into the coil part structure. By making the coil part itself conductive, the design removes the need for additional conductive components passing through the axial center, thus reducing the overall diameter.
2Reliability
If another conductive line is added to achieve conductive function, then the conductive requirement is met, but the structure becomes more complex and diameter increases
Solution Approach 1:
The patent combines multiple functions (mechanical support and electrical conduction) into a single coil part. The coil part serves both as the structural element providing bending capability and as the conductive path, thereby reducing structural complexity and eliminating the need for additional conductive lines.
Solution Approach 2:
The coil part is designed to perform multiple functions simultaneously: it provides the bending mechanism for the catheter and serves as the conductive path for electrical signals or power. This multi-functionality reduces the overall number of components and simplifies the device structure.
