Wearable electronic devices face challenges in efficiently arranging antennas and electrodes within limited housing spaces, compromising aesthetics and functionality due to spatial constraints.
Innovation Solution
A wearable electronic device design that includes a housing with a first surface, a second surface, and a side surface, featuring a first electrode area on the front and side surfaces, an antenna divided through the electrode area, and a second electrode area on the rear surface, allowing for biometric signal acquisition and wireless communication while maintaining a compact and aesthetically pleasing form factor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the antenna and electrodes are arranged in the housing, then wireless communication and biometric information acquisition functions are achieved, but the arrangement space is limited and aesthetic constraints are compromised
Solution Approach 1:
The housing surface is divided into multiple electrode areas (first electrode area on front/side surfaces, second electrode area on rear surface) and segment areas that separate the antenna from electrodes. This segmentation allows independent optimization of each component's position and shape, enabling both communication and biometric functions within limited space without compromising aesthetics.
Solution Approach 2:
The antenna is designed to be divided through the first electrode area and segment area, utilizing three-dimensional spatial arrangement rather than simple two-dimensional placement. The antenna wraps around or integrates with the housing structure, effectively using the depth and curvature of the housing to accommodate both antenna and electrode areas in a compact configuration.
2Shape
If the antenna is formed utilizing housing, then aesthetic appearance is maintained, but arrangement flexibility for electrodes is reduced
Solution Approach 1:
The housing surface is segmented into distinct functional zones: first electrode area on front and side surfaces, second electrode area on rear surface, and segment areas that separate antenna regions from electrode regions. This segmentation provides arrangement flexibility for electrodes while maintaining the aesthetic integrity of the housing design.
Solution Approach 2:
The housing structure serves multiple functions simultaneously: it provides the aesthetic outer shell, contains the antenna formation areas, accommodates multiple electrode areas for both biometric sensing and touch input, and includes segment areas that serve as both visual dividers and functional separators. This multi-functionality resolves the contradiction between aesthetic appearance and arrangement flexibility.
3Adaptability or versatility
If multiple electrodes are positioned in limited areas, then biometric signal acquisition is enabled, but spatial constraints compromise functionality
Solution Approach 1:
Multiple electrodes are distributed across segmented areas: first electrode area on front and side surfaces, second electrode area on rear surface, with segment areas providing separation. This segmentation allows sufficient spacing between electrodes for proper biometric signal acquisition while utilizing all available surfaces of the housing to maximize electrode placement options within limited space.
