Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an elasticity layer is added to enable deformable function, then flexibility and adaptability are improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The light emitting element is embedded within the elasticity layer, with the elasticity layer forming a recess that houses the light emitting element. This nesting arrangement allows the elasticity layer to provide deformable function while maintaining a compact structure and exposing the light emitting region for optical performance.
Solution Approach 2:
The elasticity layer is designed as a thin film structure that can be stretched and deformed. The layer includes a recess that accommodates the light emitting element, allowing the overall structure to be flexible while maintaining functional integrity during deformation.
2Illumination intensity
If the elasticity layer is made thinner to reduce impact on optical performance, then light emission quality is improved, but structural strength and protection capability deteriorate
Solution Approach 1:
The light emitting element is nested within a recess of the elasticity layer, allowing the elasticity layer to be thin for optimal light emission while the recess structure provides structural support and protection for the embedded light emitting element.
Solution Approach 2:
The recess structure acts as an intermediary between the thin elasticity layer and the light emitting element, providing mechanical support and protection to the light emitting element while allowing the elasticity layer to remain thin for optimal optical performance.
3Adaptability or versatility
If the connecting region is designed to have large size difference before and after stretching, then flexibility and deformability are improved, but manufacturing precision requirements increase
Solution Approach 1:
The light emitting element is precisely positioned within a recess in the elasticity layer's connecting region. This nesting design allows the connecting region to be engineered with specific geometric features that enable controlled deformation while maintaining manufacturing feasibility through standardized recess formation processes.

AI summary
A stretchable electronic device includes a first electronic unit including a first light emitting element, a second electronic unit including a second light emitting element and disposed adjacent to the first electronic unit, and an elasticity layer having a connecting region connecting the first display unit and the second display unit. In a top view of the stretchable electronic device, a size difference between the connecting region before stretching and the connecting region after stretching is greater than a size difference between the first electronic unit before stretching and the first electronic unit after stretching.
