Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the wearable device maintains a fixed configuration, then the device structure is simple and reliable, but the device cannot adapt to different user states (exercising vs. resting) affecting comfort and functionality
Solution Approach 1:
The wearable device incorporates a deformable wearable region that can dynamically change its shape and configuration based on detected user states. The controller receives biosignal information from sensors and automatically adjusts the wearable region's deformation state to match the user's activity level, transitioning between exercise mode (more secure fit) and rest mode (more comfortable fit).
Solution Approach 2:
The device uses its own biosensors to detect user state and automatically controls the deformation of its wearable region without requiring external input. The controller processes biosignal information internally and self-adjusts the device configuration, making the system self-regulating and adaptive to user needs.
2Reliability
If the wearable device is adjusted for secure wear during exercise, then the device provides better functionality during exercise, but the device becomes less comfortable during rest
Solution Approach 1:
The wearable region is designed to be dynamically deformable, allowing it to switch between two distinct configuration states: a first deformation state optimized for exercise (providing secure wear and stability) and a second deformation state optimized for rest (providing comfort and flexibility). The controller automatically transitions between these states based on detected user activity.
3Adaptability or versatility
If the wearable device uses deformable structure to adapt to user state, then the device provides enhanced comfort and functionality, but the device complexity and control difficulty increase
Solution Approach 1:
The control system operates autonomously by receiving biosignal information from integrated sensors and automatically determining user state without external intervention. The controller self-manages the deformation control based on pre-programmed logic that maps biosignal patterns to appropriate wearable region configurations, eliminating the need for manual user input or complex external control interfaces.
