Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As electronic devices become thinner and more functional, the limited space and increased number of electronic modules pose challenges to improving frequency signal emission performance.
Innovation Solution
The electronic device incorporates a display layer with a defined active area and peripheral area, featuring a circuit layer with a feeding part and light emitting elements, and a cover layer that overlaps the feeding part, which includes a coplanar waveguide, along with antenna patterns and a sensor layer with sensing electrodes, all designed to enhance frequency signal radiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of electronic modules is increased to improve device functionality, then the device becomes highly functional, but the space for mounting modules is reduced
Solution Approach 1:
The patent combines the antenna function with the display layer structure by integrating the feeding part into the circuit layer and positioning antenna patterns within the display layer, merging multiple functions (display and communication) into a single integrated structure to save space
Solution Approach 2:
The display layer is designed to serve multiple functions: it acts as both the display structure and the antenna support structure, with the circuit layer serving both driving functions and signal transmission functions for the antenna
2Length of moving object
If the device thickness is reduced to make it thinner, then the device becomes more compact, but the frequency signal emission performance deteriorates
Solution Approach 1:
The patent transitions from traditional three-dimensional antenna structures to a two-dimensional planar configuration by placing antenna patterns and feeding parts within the display layer, enabling compact integration without requiring additional thickness
Solution Approach 2:
The antenna components (feeding part and antenna patterns) are nested within the existing display layer structure, utilizing the space already allocated for display functions rather than adding separate antenna structures
