Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carbon fiber folding support assemblies for flexible screens suffer from low overall strength, brittleness, and poor heat dissipation due to resin filling, while stainless steel assemblies are heavy and have high stress.
Innovation Solution
A folding support assembly composed of resin, carbon fiber filaments, and whiskers, where the carbon fiber filaments in different layers intersect and whiskers are dispersed to enhance mechanical properties and improve heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If carbon fiber is used to manufacture the folding support assembly, then the weight is reduced and stress is lowered, but the yield strength is almost zero resulting in poor drop resistance
Solution Approach 1:
The patent uses a composite structure combining carbon fiber filaments with resin and metal whiskers. The carbon fiber provides lightweight properties, the resin acts as a binder and protective matrix, and the metal whiskers reinforce the structure to provide yield strength and drop resistance. This composite approach allows the assembly to achieve both low weight and sufficient strength.
2Stability of the object's composition
If resin fills the carbon fiber filaments, then the structure becomes more cohesive, but heat dissipation capability deteriorates
Solution Approach 1:
The patent applies local quality by using resin only as a binder between carbon fiber filaments rather than filling them completely. The resin provides structural cohesion where needed while leaving the carbon fiber filaments exposed or partially exposed to maintain thermal conductivity pathways. This selective use of resin achieves both structural stability and heat dissipation capability.

AI summary
Embodiments of the present application provides a folding support assembly, a foldable display panel and an electronic device, the folding support assembly is prepared by a new material composed of whiskers, carbon fiber filaments and resin, wherein whiskers enables most of the non-conductive carbon fiber filaments to be indirectly connected to enhance the overall toughness of the folding support assembly, so that the folding support assembly can obtain a certain yield strength, and improve the drop resistance and heat dissipation capacity of the folding support assembly; further adjustment of the mass proportions of the three can interrupt the continuity of internal stress, in addition, based on the process of preparing the folding support assembly, there is no rolling processing process like stainless steel, therefore, the stress of the folding support assembly prepared from the new material of whiskers, resin and carbon fiber filaments will also be relatively small.
