Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional wearable electronics are designed with larger size to accommodate components, then functional capabilities are improved, but comfort and wearability deteriorate
Solution Approach 1:
The wearable device is divided into multiple functional modules (sensors, processors, memory, communication units) distributed across flexible circuit boards. This segmentation allows each component to be optimized independently while maintaining overall device functionality, enabling complex capabilities in a compact form factor that fits comfortably on the body.
Solution Approach 2:
Components are nested within a layered structure consisting of flexible substrates, circuit boards, and encapsulating layers. The sensors, processors, and other elements are integrated into a compact nested arrangement that minimizes the device's overall footprint while preserving all functional capabilities, making it suitable for extended comfortable wear.
2Reliability
If wearable electronics use rigid structures to protect components, then reliability is improved, but comfort and flexibility deteriorate
Solution Approach 1:
The device employs flexible circuit boards and thin-film encapsulation layers instead of rigid protective housings. These flexible structures protect sensitive electronic components from damage while conforming to the contours of the body, maintaining both reliability and comfort during extended wear.
Solution Approach 2:
The protective structure utilizes composite materials combining flexible polymers with protective coatings. This composite approach provides adequate protection for internal components while maintaining the flexibility and comfort needed for prolonged wearable use.
3Measurement precision
If wearable electronics maintain consistent contact with the body for accurate monitoring, then measurement precision is improved, but comfort deteriorates due to intrusive sensation
Solution Approach 1:
The device features localized contact points with sensors positioned at specific locations on the flexible substrate. This local quality approach ensures consistent contact at critical measurement points while leaving other areas flexible and comfortable, allowing accurate monitoring without intrusive sensation during extended wear.
