Sliding Rollable Display Support for Flatness and Friction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with roll-structured displays face issues of display deformation and damage due to repulsive forces during winding and sliding, leading to protrusions and potential damage from friction with other structures.
Innovation Solution
The design incorporates a sliding structure with elastic and magnetic components to maintain display flatness and prevent damage, using a flexible display supported by a first and second cover, a display support member, and a sliding structure with elastic members and magnetic forces to counteract repulsive forces and reduce friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the display is wound into a roll structure to enable size adjustment, then the display can be compacted and portability is improved, but repulsive forces cause deformation and protrusions in the wound portion
Solution Approach 1:
A support member is introduced as an intermediary element between the display and the housing. This support member provides structural reinforcement to the wound portion of the display, preventing deformation and protrusions caused by repulsive forces during the winding process while maintaining the compact roll structure.
Solution Approach 2:
The support member acts as a counteracting structure that balances the repulsive forces generated during display winding. By providing opposing structural support, it neutralizes the deformation effects and maintains display flatness in the wound state.
2Adaptability or versatility
If the display is slid during expansion and contraction, then size adjustability is improved, but friction with other structures causes damage to the display
Solution Approach 1:
The support member serves as a protective intermediary between the display and the housing structures it contacts during sliding. This intermediary element reduces direct friction and contact stress on the display surface, preventing damage while enabling smooth expansion and contraction movements.
Solution Approach 2:
The support member provides preemptive protection by being positioned in advance to cushion and distribute contact forces during sliding operations. This prevents direct impact and friction damage to the display before harmful forces can cause damage.
