Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart glasses antennas are typically installed using complicated mounting bases, increasing installation difficulty and cost.
Innovation Solution
A lens processing method involving a transparent patch antenna positioned between two lens layers, with each layer protecting the antenna and simplifying assembly by adhering the antenna to one lens layer and then the other, using double-sided tape for easier stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a special mounting base or mounting bracket is provided on the frame to install the antenna, then the antenna can be fixed, but the structure becomes complicated and installation difficulty increases
Solution Approach 1:
The patent combines the antenna with the lens assembly by integrating it between the first and second lens layers. The antenna is adhered to the first lens layer, eliminating the need for separate mounting bases or brackets on the frame. This merging of functions reduces structural complexity while maintaining reliable antenna fixation.
2Reliability
If a special mounting base or mounting bracket is provided on the frame to install the antenna, then the antenna can be fixed, but installation difficulty and cost increase
Solution Approach 1:
The antenna is integrated into the lens assembly structure, being adhered between the first and second lens layers. This eliminates the need for separate mounting operations on the frame, simplifying the installation process and reducing manufacturing complexity and costs.
Solution Approach 2:
The antenna is pre-positioned and adhered to the first lens layer before final lens assembly. This preliminary action allows the antenna to be fixed in its correct position during the lens manufacturing process itself, rather than requiring separate mounting operations afterward, thereby simplifying installation.
3Adaptability or versatility
If the antenna is positioned outside the lens on the housing, then the antenna has space to be installed, but it occupies space within the housing and increases assembly complexity
Solution Approach 1:
The antenna is nested within the lens assembly structure, positioned between the first and second lens layers. This nested configuration allows the antenna to be housed within the existing lens structure without requiring additional external mounting space, thereby reducing assembly complexity while maintaining positioning flexibility.
