Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wearable electronics are used, then functionality and measurement capabilities are provided, but the devices are bulky and intrusive causing discomfort for extended wear
Solution Approach 1:
The wearable device is segmented into multiple functional components (sensors, processors, memory, communication modules) distributed across a flexible circuit board, allowing each component to be optimized independently while maintaining overall device functionality and reducing bulk
Solution Approach 2:
The device utilizes a flexible printed circuit board as the structural foundation, replacing rigid housings with thin, conformable layers that can adapt to body contours, significantly reducing device bulk and improving comfort for extended wear while maintaining structural integrity
2Ease of operation
If device size is reduced for comfort, then wearability improves, but data transmission and power management capabilities may be compromised
Solution Approach 1:
Physical data transmission ports and wired connections are replaced with wireless communication modules (Bluetooth, Wi-Fi, NFC) integrated onto the flexible circuit board, eliminating the need for bulky connectors while maintaining robust data transmission capabilities
Solution Approach 2:
The flexible circuit board serves multiple functions simultaneously: structural support, electrical connectivity, signal transmission, and antenna functionality, consolidating what would traditionally require separate components into a single integrated platform
3Adaptability or versatility
If more components are added for functionality, then measurement and monitoring capabilities improve, but device complexity and bulk increase
Solution Approach 1:
Multiple functional components (sensors, processors, memory, power management, communication modules) are merged onto a single flexible printed circuit board, reducing the number of separate parts and interconnections while maintaining full functionality and simplifying the overall device structure
Solution Approach 2:
Components are nested in a hierarchical structure where smaller functional modules are integrated within larger system layers on the flexible circuit board, with sensors embedded in conductive adhesive layers and processing elements mounted on the same substrate
