Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible displays in portable information devices are vulnerable to impact and require stable support to prevent damage when folded.
Innovation Solution
A portable information device design featuring foldable chassis members with a support plate system, including first and second plate members connected by a flexible sheet-like member, which provides stable support to the display while allowing for folding and unfolding without gaps, and includes attachment pieces and cushion members for enhanced impact resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a flexible display is used to enable folding, then the device can be miniaturized for carrying, but the display becomes vulnerable to impact and damage
Solution Approach 1:
A cushion member is placed between the rear surface of the display and the inner surface of the chassis member to provide impact absorption before damage can occur. This cushioning structure is pre-installed to protect the flexible display from impact forces during folding and usage, directly addressing the vulnerability issue while maintaining the compact folding capability.
Solution Approach 2:
The patent employs a flexible chassis member that can bend and fold, allowing the entire device structure to adapt to the flexible display's movement. This flexible shell approach enables the rigid support structures to move with the display during folding, preventing stress concentration and damage while maintaining portability.
2Strength
If the chassis is made rigid for structural support, then the display is protected, but the device cannot be folded into a compact form
Solution Approach 1:
The chassis is divided into multiple chassis members that can be folded relative to each other. This segmentation allows each segment to maintain structural strength while the overall structure can be collapsed into a compact form. The foldable chassis members are connected through hinge mechanisms that preserve structural integrity during folding operations.
Solution Approach 2:
The chassis transitions from a static rigid structure to a dynamic foldable structure. The chassis members are designed to maintain rigidity during usage but can be folded through hinge mechanisms. This dynamic capability allows the chassis to adapt between providing strong structural support and enabling compact storage, resolving the contradiction between strength and folding capability.
3Length of moving object
If the display is made thin and flexible for folding, then the device can be compact, but the display requires additional support structures increasing complexity
Solution Approach 1:
The support functions are merged into the existing chassis structure rather than adding separate support components. The cushion member is integrated between the display and chassis, while the foldable chassis members themselves provide structural support. This merging approach reduces overall device complexity while still providing necessary support for the thin flexible display.

AI summary
A portable information device is capable of stably supporting a foldable display. The portable information device has a support plate which is fixed to the inner surface sides of a first chassis member and a second chassis member and supports the rear surface of a display. The support plate has a first plate member disposed on the inner surface side of the first chassis member, a second plate member disposed on the inner surface side of the second chassis member, and a flexible sheet-like member connecting the first plate member and the second plate member so as to be foldable into a double-folded state.
