Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display panel is used to enable foldability, then the device can be folded and compacted, but the bending section lacks sufficient resistance to pressing forces
Solution Approach 1:
The patent applies composite materials by combining a flexible reinforcement main body with particles (such as metal particles, ceramic particles, or carbon particles) dispersed in a dispersion medium. This composite structure provides both flexibility from the main body and enhanced press resistance from the aggregated particles, resolving the contradiction between foldability and pressing force resistance.
Solution Approach 2:
The reinforcement body is attached specifically to the flexible section of the display panel where press resistance is needed. The aggregation section is positioned to aggregate particles precisely in the accommodation space overlapping the flexible section, providing localized enhancement of press resistance without compromising overall flexibility.
2Strength
If a reinforcement body is added to improve press resistance, then the bending section gains strength, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single reinforcement body structure. The reinforcement main body provides structural support and flexibility, while the aggregation section with dispersed particles provides press resistance. This integrated design avoids the need for separate reinforcement components, reducing overall device complexity while maintaining enhanced press resistance.
Solution Approach 2:
The reinforcement main body is designed as a flexible structure that can be integrated with the display panel's flexible section. This flexible shell approach allows the reinforcement body to conform to the display panel's shape and bending characteristics, providing structural support without adding rigid complexity that would compromise foldability.
