Flexible Display Pin Member Elastic Force Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible displays in foldable electronic devices experience deformation and creasing due to repeated folding and unfolding, leading to a decrease in surface quality and portability.
Innovation Solution
A design incorporating a support plate and elastic member that compresses or tensions a pin member, providing an elastic force to counteract the reaction force on the flexible display, maintaining its surface quality and preventing lifting or creasing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display is widened to provide various functions, then the usability is improved, but the portability decreases
Solution Approach 1:
The display device is designed to dynamically change its configuration between unfolded and folded states. The flexible display and housing can transition from an extended flat configuration (providing wide screen for usability) to a compact folded configuration (improving portability), allowing the device to adapt to different usage scenarios and carry requirements
2Length of moving object
If the flexible display is folded and unfolded repeatedly, then the portability is improved, but permanent deformation occurs leading to surface quality degradation
Solution Approach 1:
A support plate is introduced to preemptively counteract the deformation forces that occur during folding and unfolding. The support plate is positioned to overlap with the flexible display's flexible region and provides structural reinforcement that prevents permanent deformation, creasing, and lifting before they can occur, thereby maintaining surface quality despite repeated folding operations
Solution Approach 2:
The support plate acts as an intermediary element between the flexible display and the housing structure. It mediates the mechanical stresses during folding by distributing forces and providing a rigid backing to the flexible region, preventing direct contact between opposing forces that would cause deformation and surface quality degradation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces deformation and maintains the surface quality of the flexible display by counteracting the reaction force generated during folding and unfolding, enhancing both usability and portability.
