Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the outer conductor is deformed to reduce the distance between conductors to improve transmission characteristics, then transmission characteristics are improved, but it requires specialized equipment and the amount of deformation is difficult to control
Solution Approach 1:
The patent changes the physical state of the outer conductor from rigid to flexible by introducing a flexible section with reduced stiffness. This allows the outer conductor to be deformed to a predetermined shape that reduces the distance between conductors in the intermediate portion, improving transmission characteristics without requiring specialized deformation equipment. The flexible section's stiffness is specifically designed to be lower than other portions, enabling easy deformation while maintaining control over the deformation amount through its predetermined shape.
2Reliability
If the outer conductor is deformed to reduce the distance between conductors, then transmission characteristics are improved, but the deformation amount is difficult to control precisely
Solution Approach 1:
The patent applies preliminary action by pre-forming the flexible section of the outer conductor into a predetermined deformed shape during manufacturing. This predetermined shape is designed to achieve the optimal reduction in distance between conductors. When the connector is assembled, this pre-formed deformation is automatically realized without requiring additional deformation steps, ensuring precise control over the deformation amount and consistent transmission characteristics across all units.
3Reliability
If equipment is used to cause deformation of the outer conductor, then the distance between conductors can be reduced, but the manufacturing process becomes more complex
Solution Approach 1:
The patent extracts the deformation function from the manufacturing equipment and incorporates it directly into the outer conductor structure itself. By creating a flexible section with reduced stiffness that can be pre-formed into a predetermined shape, the need for specialized deformation equipment is eliminated. The deformation capability is taken out from the external equipment and built into the component design, simplifying the overall manufacturing process while maintaining the ability to reduce the distance between conductors for improved transmission characteristics.
