Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If disposable patch design is used, then device cost and maintenance requirements are reduced, but device complexity increases due to multiple layered components
Solution Approach 1:
The monitoring device is divided into multiple functional layers including adhesive layer, electrode layer, sensor layer, battery layer, and protective layer. Each layer performs a specific function and can be manufactured separately using standard manufacturing processes, reducing overall device cost while maintaining functionality.
Solution Approach 2:
Multiple functional components are merged into a single integrated patch structure. The adhesive, electrodes, sensors, battery, and protective elements are combined in a compact multi-layer configuration, simplifying the overall device while providing comprehensive monitoring capabilities.
2Adaptability or versatility
If multiple layered components are integrated, then device functionality is improved, but manufacturing precision requirements increase
Solution Approach 1:
The device is segmented into discrete layers that can be manufactured using standard processes and then assembled through lamination. This segmentation allows each layer to be optimized independently while maintaining overall functionality, reducing the precision requirements for the entire device.
Solution Approach 2:
The device uses flexible thin film layers for electrodes, sensors, and protective coverings. These thin films can be manufactured with standard precision and conform to the skin surface, providing versatile functionality without requiring extreme manufacturing precision.
3Object-affected harmful factors
If sealed construction is implemented, then water resistance and environmental protection are improved, but device complexity increases
Solution Approach 1:
A flexible protective layer is sealed over the entire device structure, creating a water-resistant barrier. This thin film enclosure protects internal components from environmental factors while maintaining the compact, multi-layer design without adding significant complexity.
Solution Approach 2:
The protective sealing function is merged with the existing layered structure. The protective layer serves both as an environmental barrier and as part of the overall device assembly, eliminating the need for separate sealing mechanisms and reducing overall complexity.
