Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the frame is divided to prevent interference between electrodes, then biometric measurement capability is improved, but durability and waterproofness are degraded
Solution Approach 1:
The frame is segmented into multiple conductive regions with different electrical properties (first conductive region, second conductive region, third conductive region) that are electrically isolated from each other. This segmentation allows multiple biometric sensors to be integrated without electrical interference while maintaining the frame's structural integrity and waterproofness through non-conductive seals between regions.
Solution Approach 2:
Different regions of the frame are assigned different electrical characteristics - some regions are conductive for electrode function, while non-conductive regions provide isolation and sealing. This local differentiation of material properties enables simultaneous achievement of electrical isolation for sensor compatibility and structural continuity for durability and waterproofing.
2Adaptability or versatility
If multiple electrodes are integrated for various biometric signals, then measurement function versatility is improved, but frame structure complexity increases
Solution Approach 1:
The frame serves multiple functions simultaneously: it provides structural support, acts as a housing for the display, and incorporates multiple conductive regions that function as electrodes for different biometric measurements (ECG, GSR, BIA). This multi-functionality reduces the need for separate components and simplifies the overall device structure while enabling versatile biometric measurement capabilities.
Solution Approach 2:
The frame structure is merged with the electrode system by integrating conductive regions directly into the frame body. This combination eliminates the need for separate electrode components and their associated mounting structures, thereby reducing device complexity while maintaining the capability to measure multiple biometric signals through the integrated conductive regions.
3Adaptability or versatility
If a separate contact point such as a key is mounted on the frame, then electrode functionality is improved, but space and design flexibility are limited
Solution Approach 1:
The electrode functionality is merged directly into the frame structure through integrated conductive regions, eliminating the need for separate contact points or keys mounted on the frame. This integration frees up space and design flexibility while maintaining full electrode functionality for biometric measurements.
Solution Approach 2:
The frame is designed to serve as both the structural housing and the electrode contact surface through its conductive regions. This multi-functional design eliminates the need for dedicated separate contact points, thereby improving space utilization and design flexibility while maintaining electrode functionality for various biometric measurements.
