Foldable Display Housing Structure for Stress and Wiring Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices with flexible displays face challenges due to deformation and damage from repeated folding, particularly due to inadequate housing designs that do not account for the flexible display's characteristics and the stress on wiring members.
Innovation Solution
A foldable housing structure with recesses and asymmetrical widths to accommodate the flexible display, along with a bracket assembly and hinge structure that includes a wiring member protection mechanism to prevent damage during folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display is used in a foldable electronic device, then both portability and a large screen can be provided, but the display may be deformed or damaged when the device is folded due to inadequate housing design
Solution Approach 1:
The housing includes a flexible display panel that can bend and fold without breaking. The flexible display is integrated into the housing structure, allowing the device to be folded into smaller forms while maintaining display functionality and integrity during repeated folding operations
Solution Approach 2:
The housing structure includes reinforcement elements and protective layers positioned strategically around the flexible display before folding occurs. These pre-positioned structural features cushion and protect the display from damage during the folding process, preventing deformation and extending device lifespan
2Adaptability or versatility
If the electronic device is folded repeatedly, then portability is improved, but stress is applied to the wiring member causing damage
Solution Approach 1:
The wiring member transitions from a rigid structure to a flexible configuration that can accommodate repeated folding. The wiring is designed with increased flexibility parameters, allowing it to bend without breaking during repeated folding operations while maintaining electrical connectivity between device components
Solution Approach 2:
Protective structures are pre-positioned around the wiring member to cushion and distribute stress during folding. These protective elements are integrated into the housing design before the device is subjected to repeated folding, preventing wiring damage and maintaining connection integrity

AI summary
An electronic device includes a foldable housing including a first housing structure and a second housing structure that are foldably connected with each other and that form a recess together and a flexible display located in the recess. The flexible display includes a first part located in the first area of the recess and having a first gap from the first portion of the second housing structure in the unfolded state, the first part including a first peripheral portion facing the first portion of the second housing structure and a second part located in the second area of the recess and having a second gap from the second portion of the second housing structure, the second part including a second peripheral portion facing the second portion of the second housing structure, in which the second gap is smaller than the first gap in the unfolded state.
