Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the base is extended to achieve stretchability, then the substrate can be attached to curved surfaces, but the line may be disconnected and durability is lowered
Solution Approach 1:
The base is divided into frame regions and opening regions, creating a segmented structure that allows selective placement of electronic components and lines in frame regions while opening regions provide flexibility and stress relief during stretching
Solution Approach 2:
Different regions of the base have different properties: frame regions provide structural support and electrical connectivity, while opening regions provide flexibility and stress relief. The line is disposed in the frame region where it has better mechanical support and resistance to disconnection during stretching
2Duration of action of stationary object
If the stretchable electronic substrate is applied to skin for extended periods, then continuous monitoring is possible, but air permeability is blocked and skin damage occurs
Solution Approach 1:
The base includes opening regions that create a porous structure, allowing air to pass through the substrate when applied to the skin. This maintains skin breathability and prevents irritation during extended wear while still providing continuous monitoring capability
