Smart Glasses Wiring Body With Mesh Antenna for Low Lens Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart glasses struggle to suppress the visibility of conductor patterns on lens bodies while improving antenna characteristics.
Innovation Solution
A wiring body is designed with a base board, a ground pattern, and a conductor portion comprising a first and second conductor pattern made of metal. The second conductor pattern is mesh-like and connected to the first, allowing the conductor portion to be arranged in a bent state, thereby reducing visibility on the lens body and enhancing antenna characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a transparent electrode is arranged as an antenna on a lens body, then the antenna characteristics are improved, but the visibility of the conductor pattern increases
Solution Approach 1:
The conductor pattern is divided into two separate patterns: a first conductor pattern on the lens body and a second conductor pattern on the temple arm, connected through the hinge mechanism. This segmentation allows the antenna function to be distributed while reducing the visibility impact on the lens body.
Solution Approach 2:
The conductor pattern is extended from a two-dimensional pattern on the lens body to a three-dimensional configuration that includes the hinge mechanism and temple arm. This dimensional transition allows the conductor to maintain electrical continuity while being positioned in different spatial locations to reduce visibility.
2Object-generated harmful factors
If the conductor pattern is made mesh-like to reduce visibility, then the aesthetic appearance is improved, but the electrical conductivity may be reduced
Solution Approach 1:
Different regions of the conductor pattern have different properties: the first conductor pattern on the lens body is designed with mesh-like structure for aesthetic purposes, while the second conductor pattern on the temple arm and the hinge connection are designed with adequate conductivity to ensure proper antenna function.
Solution Approach 2:
The conductor pattern uses metal materials with high conductivity arranged in a mesh configuration, combining the aesthetic benefits of reduced visibility with the electrical benefits of metal conductivity. The mesh structure is optimized to maintain sufficient electrical performance while achieving the desired aesthetic appearance.
3Adaptability or versatility
If the conductor portion is arranged in a bent state to fit the glasses structure, then the adaptability to glasses design is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The hinge mechanism provides dynamic flexibility to the conductor pattern, allowing it to adapt to different glasses configurations and bending states. This dynamic capability enables the conductor to maintain proper alignment and electrical continuity despite variations in the glasses structure and wear conditions.
Solution Approach 2:
The hinge mechanism serves as an intermediary element that connects the first and second conductor patterns, accommodating bending and alignment variations. This intermediary structure absorbs manufacturing tolerances and structural variations, maintaining electrical continuity without requiring extremely high manufacturing precision.

AI summary
A wiring body includes a base board, a ground pattern provided on the base board, and a conductor portion including a first conductor pattern and a second conductor pattern containing metal. The ground pattern is a conductor pattern extending so as to form a planar surface. The second conductor pattern is a mesh-like conductor pattern connected to the first conductor pattern. The conductor portion is able to be arranged in a bent state.
