Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing housing assemblies with electrochromic assemblies require a reserved space for antenna clearance, leading to increased frame width and limited color-changing areas, affecting appearance aesthetics and antenna reliability.
Innovation Solution
Integrate a communication antenna on a conductive layer within the electrochromic assembly, surrounded by an isolation area, allowing the antenna to function without being shielded, and reduce the frame area by integrating the antenna into the conductive layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electrochromic assembly uses a conventional conductive layer structure with shielding effect, then the antenna function is protected from interference, but the frame area width increases and edge color-changing capability is lost
Solution Approach 1:
The conductive layer is segmented into distinct functional zones: an antenna area for signal transmission and a conductive area for electrochromic control. This segmentation allows each zone to perform its specific function without interfering with the other, eliminating the need for a wide non-color-changing frame area while maintaining antenna reliability.
Solution Approach 2:
Different regions of the conductive layer are assigned different electrical properties and functions. The antenna area has optimized conductivity for signal transmission, while the conductive area provides electrochromic control. This local differentiation enables the entire frame area to participate in color-changing while the antenna maintains its function.
2Reliability
If the electrochromic assembly reserves a specific space as antenna clearance area, then the antenna can function without shielding, but the color-changing area is reduced and appearance aesthetics deteriorate
Solution Approach 1:
The antenna area and conductive area are merged into a single integrated conductive layer structure. The isolation area provides electrical separation while allowing physical integration, enabling the antenna to function within the color-changing region without requiring separate clearance space, thus maximizing the color-changing area while maintaining antenna reliability.
3Device complexity
If the antenna area and conductive area are directly connected without isolation, then the structure is simplified, but the antenna is shielded by the conductive layer reducing reliability
Solution Approach 1:
An isolation area is introduced as an intermediary region between the antenna area and conductive area. This isolation area acts as an electrical mediator that prevents shielding effects while maintaining the integrated structure, thus preserving antenna reliability without significantly increasing structural complexity.
