Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices experience decreased antenna radiation efficiency due to the presence of metal elements or structures, which can interfere with the antenna's performance, necessitating an improved antenna structure that enhances radiation efficiency without interference.
Innovation Solution
The electronic device incorporates a conductive member, such as a camera deco, as a radiator, positioned close to the antenna and connected via conductive gaskets to a printed circuit board, allowing it to operate as a radiator for wireless communication, thereby increasing radiation efficiency and the antenna's radiation region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a conductive member is disposed around the antenna, then the antenna can be compactly integrated with other components, but the radiation efficiency of the antenna decreases due to interference from the conductive member
Solution Approach 1:
The patent merges the conductive member (camera deco) with the antenna system by electrically connecting them through conductive gaskets. The conductive member is positioned adjacent to the antenna pattern and connected via gaskets to form an integrated radiating structure, combining what were previously separate components into a unified antenna system that achieves both compact integration and improved radiation efficiency
Solution Approach 2:
The conductive member serves dual functions: it acts as a structural component (camera deco) and simultaneously functions as part of the antenna radiating element. By making the conductive member electrically connected to the antenna pattern through gaskets, it becomes a multi-functional element that provides both mechanical support and electromagnetic radiation capabilities
2Volume of moving object
If the antenna is disposed close to conductive members, then the device size is reduced, but the radiation region of the antenna is limited
Solution Approach 1:
The patent extends the radiating structure into the spatial dimension by incorporating the conductive member adjacent to the antenna pattern. This creates a two-dimensional or three-dimensional radiating configuration rather than a simple planar antenna, thereby expanding the radiation region while maintaining compact device dimensions through vertical or lateral integration
