Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple receiving antenna channels are added to improve detection coverage, then field of view is improved, but device complexity increases
Solution Approach 1:
The multiple receiving antenna channels serve multiple functions simultaneously. The same antenna channels that provide broad field of view coverage also enable both short-range and long-range detection capabilities through their different spacing configurations. This multi-functionality reduces the need for additional specialized components.
Solution Approach 2:
The patent combines short-range detection channels and long-range detection channels into a single integrated receiving antenna unit. By merging these functions into one unified structure with four channels, the system achieves comprehensive detection coverage while avoiding the complexity of separate independent antenna systems.
