Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the OMT is directly attached to the antenna, then the mechanical structure is simple, but the OMT is exposed to external mechanical forces and stress
Solution Approach 1:
A frame structure is introduced as an intermediary component between the antenna and the OMT. The frame includes a supporting surface for the antenna interface device and a receiving section for the OMT, creating a mechanical decoupling that prevents external forces from being transmitted to the OMT while maintaining structural connection.
Solution Approach 2:
The mounting structure is segmented into distinct functional sections: the antenna interface device with supporting surface, the frame structure with receiving section, and the OMT mounting section. This segmentation allows each component to perform its specific function independently, with the frame acting as a force-isolating intermediary.
2Reliability
If the OMT design is optimized for RF signal processing, then the signal processing capability is improved, but the weight optimization is limited due to mechanical strength requirements
Solution Approach 1:
The frame structure serves as a mechanical intermediary that assumes the load-bearing function, allowing the OMT to be designed with minimal weight for optimal RF performance. The frame's structural strength compensates for the reduced weight of the OMT, maintaining overall system integrity while enabling weight optimization of the critical RF component.
3Stability of the object's composition
If fastening sections are made rigid for secure attachment, then the mechanical stability is improved, but mechanical tolerances and alignment precision deteriorate
Solution Approach 1:
The fastening sections incorporate elastically deformable zones that change their mechanical parameters under load. These zones provide initial rigidity for stable attachment but allow controlled deformation to compensate for manufacturing tolerances, enabling both mechanical stability and alignment precision to be achieved.
Solution Approach 2:
The fastening sections include elastically deformable zones with C-shaped cross-sections that function as flexible elements. These zones can deform elastically to accommodate tolerance variations in the antenna and OMT interfaces while maintaining secure attachment, resolving the contradiction between rigidity and tolerance compensation.
4Object-affected harmful factors
If the frame is designed to isolate the OMT from external forces, then the OMT is protected from stress, but the device complexity increases
Solution Approach 1:
The frame structure performs multiple functions simultaneously: it provides mechanical support for both the antenna interface device and the OMT, isolates the OMT from external forces, and enables weight optimization of the OMT. By consolidating these functions into a single multi-functional component, the overall device complexity is minimized while achieving stress protection.

Implementation Method 1
at least one of said two fastening sections comprises an elastically deformable zone. This enables to temporarily deform said elastically deformable zone thus providing a restoring force to the frame or e.g. the antenna interface device
