Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wearable sensor device is designed to be lightweight and comfortable for continuous wear, then user comfort and ease of operation are improved, but the device may require frequent replacement of adhesive layers to maintain skin attachment quality
Solution Approach 1:
The adhesive system is divided into multiple independent adhesive layers that can be individually removed and replaced. This segmentation allows the sensor device to maintain comfortable continuous wear while extending the overall attachment duration by rotating through multiple adhesive layers, preventing any single layer from degrading too quickly.
Solution Approach 2:
The patent implements a system where used adhesive layers are discarded and fresh adhesive layers are activated from the stack. This allows the device to maintain optimal skin attachment quality throughout extended monitoring periods by periodically replacing depleted adhesive layers, thereby extending the functional lifespan of the wearable device.
2Duration of action of moving object
If the wearable device uses multiple stacked adhesive layers to extend usage life, then duration of action is improved, but the device complexity increases due to additional layers and removal mechanisms
Solution Approach 1:
The adhesive system is segmented into multiple independent layers stacked together, each capable of independent removal. This segmentation extends device usage life by allowing sequential activation of fresh adhesive layers while maintaining a relatively simple overall structure that leverages the natural properties of individual adhesive layers.
3Reliability
If the sensor device is designed for disposable use to ensure sanitation and reliability, then reliability is improved, but loss of substance increases due to frequent device replacement
Solution Approach 1:
The device is segmented into disposable and reusable components. The sensor module and electronics can be reused, while only the adhesive layers and contact surfaces are disposable. This segmentation maintains sanitation and reliability by ensuring fresh contact surfaces for each monitoring period while reducing material consumption by preserving the valuable electronic components.
Solution Approach 2:
The patent implements a system where only the adhesive layers are discarded after use, while the sensor device itself is recovered and reused. This approach ensures sanitation by providing fresh adhesive surfaces for each patient or monitoring period while significantly reducing material consumption compared to complete device disposal.
4Reliability
If the adhesive layers are made strong to ensure secure attachment, then reliability of attachment is improved, but mechanical stress on the skin increases causing irritation
Solution Approach 1:
The attachment system is segmented into multiple adhesive layers that share the mechanical stress load. Each layer provides moderate adhesion strength, and the distributed stress across multiple layers reduces skin irritation while maintaining overall attachment security throughout the monitoring period.
Solution Approach 2:
The stacked adhesive layers provide a cushioning effect that distributes mechanical stress away from the skin. By having multiple layers rather than one strong layer, the system prevents excessive stress concentration that would cause skin irritation while maintaining reliable attachment.
