Wearable Antenna Layout Using Temple Components and Ground Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable electronic devices face challenges in accommodating antennas due to their small and lightweight design, which limits the physical space available for antenna disposition.
Innovation Solution
The wearable electronic device utilizes the ground area and electronic components, such as sound output modules, batteries, or motors, disposed on the temples as antennas, eliminating the need for a separate antenna disposition space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wearable electronic device is designed to be small-sized and light-weight, then the convenience of wearing is improved, but the disposition space for antenna is reduced
Solution Approach 1:
The patent merges the antenna function with existing structural components (ground area and electronic components) that are already present in the wearable device. By combining multiple functions into existing components, the design achieves wireless communication capability without adding separate antenna structures, thus maintaining the compact and lightweight design while enabling antenna functionality.
Solution Approach 2:
The ground area and electronic components are designed to serve dual purposes: their original functions plus antenna radiation functions. This multi-functionality allows the same components to perform both their primary roles and wireless communication, eliminating the need for dedicated antenna space and resolving the contradiction between device compactness and antenna disposition requirements.
2Reliability
If a separate antenna disposition space is provided, then the wireless communication function is improved, but the device size and weight increase
Solution Approach 1:
The antenna function is merged with existing structural components (ground area and electronic components) that are already present in the wearable device. By combining multiple functions into existing components, the design achieves wireless communication capability without adding separate antenna structures, thus maintaining the compact and lightweight design while enabling antenna functionality.
Solution Approach 2:
Existing components (ground area and electronic components) are made to serve themselves by performing both their original functions and antenna radiation functions. This self-service approach eliminates the need for separate dedicated antenna components, allowing the device to achieve wireless communication without additional weight or size.
