Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable electronic devices with multiple antennas face communication performance issues due to physical positioning, leading to reduced or distorted antenna signal radiation areas when worn on the head, limiting their compact and aesthetic design.
Innovation Solution
The electronic device incorporates a main body with rotatable supports and multiple antennas, including a communication module, a relay module, and directional antennas, which radiate and receive signals across different frequency bands to overcome radiation shading caused by the user's head, ensuring efficient communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the wearable device is made compact and lightweight to improve aesthetic design and portability, then the device size and weight are reduced, but the antenna signal radiation area is reduced or distorted due to radiation shading from the user's head
Solution Approach 1:
The patent divides the antenna system into multiple segments: a first antenna in the first support and a second antenna in the second support. This segmentation allows each antenna to serve specific communication functions and positions them to avoid radiation shading from the user's head, thereby maintaining communication reliability while keeping the device compact.
Solution Approach 2:
The patent utilizes spatial dimensionality by placing antennas in different supports (first support and second support) that are positioned at different locations and orientations. This three-dimensional arrangement ensures that at least one antenna maintains an optimal radiation area away from the user's head, solving the contradiction between compactness and communication performance.
2Reliability
If multiple antennas are added to improve communication performance, then signal radiation coverage is enhanced, but the device complexity and arrangement space requirements increase
Solution Approach 1:
The patent combines the communication module with the relay module in an integrated manner. The communication module includes both the first antenna (for communicating with external devices) and the second antenna (for communicating with the relay module), reducing the number of separate components and simplifying the overall device structure while maintaining multiple antenna functions.
Solution Approach 2:
The second support serves multiple functions: it holds the relay module for signal relaying and also positions the second antenna for wireless communication. This multi-functionality reduces the need for additional dedicated structures, thereby reducing device complexity while achieving improved communication performance through multiple antennas.
3Volume of moving object
If the communication module is positioned close to the user's head to reduce device size, then the device becomes more compact, but the antenna signal radiation area is blocked or distorted by the user's head
Solution Approach 1:
The patent applies local quality by positioning the second antenna specifically in the second support at a location and orientation that avoids radiation shading from the user's head. This localized optimal positioning ensures that the antenna's signal radiation area is not blocked, even though the device is compact and worn close to the head.
