Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing wearable devices use fixed structural configuration, then manufacturing is simpler, but adaptability to different limb sizes is poor
Solution Approach 1:
The wearable device is divided into multiple sensor pods that can be independently positioned along the limb. Each pod contains sensing elements and can be spaced at different intervals, allowing the device to adapt to various limb circumferences and shapes while maintaining functional coverage.
Solution Approach 2:
The device incorporates adjustable and reconfigurable structural elements that allow users to modify the device configuration based on their specific needs. This includes adjustable coupling mechanisms between sensor pods and reconfigurable electrode arrangements, enabling the same device to fit different limb sizes and types.
2Measurement precision
If wearable device uses rigid fixed structure, then structural stability is maintained, but fit accuracy on varying limb shapes is poor
Solution Approach 1:
Different portions of the wearable device have different structural properties optimized for their specific functions. Sensor pods containing sensitive biosensors maintain rigid structures for stability, while coupling arms and connection elements use more flexible materials to accommodate limb shape variations and achieve better overall fit.
Solution Approach 2:
The device allows adjustment of key structural parameters such as inter-pod spacing, coupling arm length, and electrode positioning. These parameter changes enable the device to adapt to different limb circumferences, lengths, and shapes while maintaining adequate sensor contact and signal quality.
3Adaptability or versatility
If wearable device uses non-adjustable circumference, then device structure is simpler, but applicability to different users is limited
Solution Approach 1:
The wearable device is designed with universal adjustment mechanisms that allow a single device model to serve multiple user groups across different limb sizes. The sensor pods can be repositioned and recoupled in various configurations, enabling the device to adapt to children, adults, and different limb types without requiring multiple specialized models.
