Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display panel is made stretchable to enable deformation, then adaptability and versatility are improved, but image quality deteriorates when stretched or contracted
Solution Approach 1:
The display panel is divided into multiple rigid areas that maintain fixed internal structures, connected by stretchable areas. This segmentation allows different regions to have different mechanical properties - rigid areas preserve image quality while stretchable areas enable deformation.
Solution Approach 2:
The connection between rigid areas transitions from static to dynamic through the introduction of stretchable areas with elastic connection members. These dynamic connections can adapt their length and tension state based on deformation requirements, maintaining image quality during static phases while enabling movement when needed.
2Manufacturing precision
If rigid areas are introduced to maintain image quality, then manufacturing precision is improved, but device complexity increases due to multiple components
Solution Approach 1:
Multiple functional layers (reflection adjustment layer, optical adjustment layer, anti-moisture member, adhesive member) are merged into an integrated structure within each rigid area. This consolidation maintains precise optical and protective functions while reducing the number of separate components and assembly steps.
Solution Approach 2:
The rigid areas serve multiple functions simultaneously: they provide structural support for image quality, housing for optical adjustment layers, protection through anti-moisture members, and adhesion through adhesive members. This multi-functionality reduces overall device complexity by eliminating the need for separate components for each function.
3Adaptability or versatility
If elastic connection members are used to enable stretching, then adaptability is improved, but reliability deteriorates due to potential connection failure
Solution Approach 1:
The elastic connection members utilize composite material structures combining stretchable polymers with reinforcing elements. This composite approach provides both the necessary elasticity for stretching and the strength for reliable connections, overcoming the limitation of single-material designs.
Solution Approach 2:
The adhesive members are designed with beforehand cushioning characteristics, providing gradual bonding strength development and stress distribution. This prevents sudden connection failures by cushioning against shock loads and fatigue stresses that occur during repeated stretching cycles.

Implementation Method 1
first elastic members attached between rear surfaces of the stretchable lines and the rigid areas, stretched by an external force and contracted by an elastic force; and second elastic members attached between front surfaces of the stretchable lines and the rigid areas, stretched by an external force and contracted by an elastic force
Implementation Method 2
the reflection adjustment layer comprises an organic layer in which a dye is dispersed and an organic layer in which a pigment is dispersed, to absorb light in a predetermined wavelength range and transmit light in other wavelength ranges
Implementation Method 3
each of the rigid areas comprises an optical adjustment layer formed on a front surface of the reflection adjustment layer defined by the partition wall to refract and scatter light after the light has transmitted the reflection adjustment layer
