Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal fastener elements are used to fasten the antenna on a support, then the antenna can be securely mounted, but the metal fastener elements hinder the operation of the antenna and compromise RF communication performance
Solution Approach 1:
The patent combines the fastening function and the antenna radiating function into a single integrated structure. The fastener element is designed to simultaneously fasten the antenna to the support and serve as a radiating element for RF signals, eliminating the harmful interference caused by separate metal fasteners.
Solution Approach 2:
The fastener element is designed to perform multiple functions: mechanical fastening of the antenna and electromagnetic radiation for RF communication. This multi-functional design eliminates the need for separate fastening components that would interfere with RF performance.
2Reliability
If a traditional antenna structure is used with separate fastening elements, then the antenna can be securely mounted, but the antenna occupies a relatively large volume of the electrical equipment
Solution Approach 1:
The patent merges the fastening component and the antenna radiating element into a single integrated structure. This integration eliminates the need for separate fastening hardware and reduces the overall volume required for the antenna system within the electrical equipment.
Solution Approach 2:
The fastener element serves dual purposes as both a mechanical fastening component and an antenna radiating element. This multi-functionality reduces the total component count and volume occupied by the antenna system in the electrical equipment.
