Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless links are used to connect donor and server units in three-hop repeaters, then ease of operation is improved, but communication reliability deteriorates due to low bandwidth and dropped connections
Solution Approach 1:
The connection system is segmented into multiple functional components: donor unit sleeve with coupling antennas, server unit sleeve with coupling antennas, and physical cable. This segmentation allows each component to be optimized independently while working together to provide both ease of connection and reliable communication.
Solution Approach 2:
The physical cable acts as an intermediary medium between the donor and server units, replacing direct wireless links with a hybrid approach where the cable provides stable backbone connectivity while wireless antennas handle mobile device communication.
2Device complexity
If wireless links are used to connect donor and server units, then device complexity is reduced, but signal transmission stability deteriorates
Solution Approach 1:
The system merges wireless and wired connection technologies into a hybrid architecture where the physical cable provides stable backbone connectivity and wireless antennas handle mobile device communication, achieving both stability and ease of operation.
Solution Approach 2:
The coupling antennas on the sleeves serve multiple functions: they inductively couple signals to the physical cable for stable backbone transmission and simultaneously support wireless communication with mobile devices, making the system multi-functional.
3Ease of manufacture
If traditional wireless links are used between donor and server units, then ease of manufacture is improved, but communication speed deteriorates
Solution Approach 1:
The patent replaces the purely wireless mechanical/electromagnetic coupling system with a hybrid system that uses a physical cable (mechanical connection) for backbone signal transmission, substituting the inefficient wireless-only approach with a wired backbone that enables higher communication speeds.
