Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal is utilized on smart glasses temples and frames to provide structural integrity and thermal dissipation, then structural strength and thermal management are improved, but antenna placement and wireless communication performance deteriorate
Solution Approach 1:
The patent combines the structural metal frame with antenna functionality by integrating antenna elements directly into the temple structure. The metal temple serves dual purposes: providing structural support and acting as part of the antenna system, thereby merging structural and communication functions into a single integrated component.
Solution Approach 2:
The metal temple structure is designed to perform multiple functions simultaneously: it provides structural integrity, thermal dissipation, and antenna functionality. By making the temple multi-functional, the patent eliminates the need for separate antenna components that would consume additional space and compromise the structural design.
2Adaptability or versatility
If multiple antennas are added to smart glasses for various wireless communication frequencies, then wireless communication versatility is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent segments the temple structure into distinct functional zones, with different portions of the temple serving as different antenna elements. Each segment can be optimized for specific frequency ranges, allowing multiple antennas to coexist within the limited space of a single temple without creating a complex multi-component system.
Solution Approach 2:
The patent utilizes the three-dimensional structure of the temple, extending antenna elements along the length and curvature of the temple. By exploiting the spatial dimensionality of the temple geometry, the patent accommodates multiple antenna elements with different orientations and lengths, enabling support for various wireless frequencies without increasing overall device complexity.
