Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional sealing components (sealing rings, windows, matching cones) are used to protect electronics from high pressure, then the sealing reliability is improved, but the device complexity increases and signal transmission may be compromised
Solution Approach 1:
The patent merges the sealing function directly into the waveguide structure by creating a plastically deformed sealing area on the waveguide surface, eliminating the need for separate sealing components like rings, windows, or matching cones. The waveguide itself becomes both the signal transmission medium and the sealing element, reducing device complexity while maintaining sealing reliability in high-pressure applications up to 2000 bar
Solution Approach 2:
The waveguide structure performs self-sealing through plastic deformation of its own material when pressed against the mating surface. The sealing area deforms plastically under compression to conform to the sealing surface, creating an effective seal without requiring additional sealing components. This self-service approach eliminates extra parts while ensuring reliable sealing
2Device complexity
If a plastically deformed sealing area is used instead of additional sealing components, then the device complexity is reduced, but the sealing effectiveness under high pressure may be insufficient
Solution Approach 1:
The patent changes the physical state and mechanical properties of the sealing area by inducing plastic deformation. The sealing area is designed with specific material properties and geometric features that allow it to deform plastically under compression, conforming to the sealing surface and maintaining effective sealing even under high pressures up to 2000 bar. This parameter change from elastic to plastic deformation ensures sealing effectiveness without additional components
