Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple directional antennas are used to provide omnidirectional radio signal coverage, then communication coverage in all directions is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent combines multiple directional antenna functions into a single integrated antenna structure. The antenna includes a conductive element with multiple radiating sections arranged in different directions, allowing one antenna to provide omnidirectional coverage that would traditionally require multiple separate antennas. This merging reduces device complexity while maintaining versatile coverage.
Solution Approach 2:
The antenna structure is designed to perform multiple functions simultaneously - it provides directional beams in multiple directions while also offering omnidirectional coverage. The conductive element is configured with radiating sections that can serve different communication directions, making a single antenna universal for multiple communication zones rather than requiring dedicated antennas for each direction.
2Area of stationary object
If antenna structure is integrated into the housing, then additional antenna space is saved, but manufacturing precision requirements increase
Solution Approach 1:
The antenna structure is merged with the housing components - the conductive element is integrated into the housing body or attached to housing surfaces. This integration eliminates the need for separate antenna mounting spaces and reduces the overall device footprint while maintaining antenna functionality through precise structural design.
3Speed
If conductive element with slots is used for millimeter wave communication, then high-speed communication capability is improved, but manufacturing complexity increases
Solution Approach 1:
The conductive element incorporates slot structures that create a porous or perforated pattern on the antenna surface. These slots are designed with repeating patterns that can be manufactured using standard fabrication techniques such as etching or punching. The slot geometry and distribution are optimized for millimeter wave performance while maintaining manufacturability through regular, repeatable patterns rather than complex irregular shapes.
