Wearable Antenna Layout Using Temple Ground and Components

Solution Overview

Problem

Wearable electronic devices face challenges in accommodating antennas due to their small size and lightweight design, limiting physical disposition space for wireless communication.

Innovation Solution

Utilize the ground area and electronic components on the temples of wearable devices, such as sound output modules, batteries, or motors, as antennas without requiring additional space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wearable electronic devices are designed to be small-sized and light-weight, then convenience of wearing is improved, but disposition space for antenna is reduced

Engineering Contradiction:

Improveconvenience of wearingVSAvoiddisposition space for antenna

Core Design Contradiction:

Ease of operationVSArea of stationary object

Solution Approach 1:

The patent combines the antenna function with existing structural components (ground area and electronic components) that are already present in the wearable device. By merging the antenna radiator function with components that would otherwise serve other purposes, the design eliminates the need for separate antenna space while maintaining wireless communication capability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent makes existing components multi-functional by enabling them to serve as antenna radiators in addition to their original functions. The ground area and electronic components become dual-purpose elements, simultaneously performing their original roles and serving as antenna elements for wireless communication.

Inventive Principle:

Principle #6Universality (Multi-functionality)
