Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable displays face challenges in achieving a thin profile and improved mobility due to the thickness added by multiple plate members when folded, which limits their flexibility and usability.
Innovation Solution
A foldable display design featuring a flexible panel connected to first and second plates, with a slide plate and rotary plates that allow the panel to be folded into an S-shape and unfolded flat, eliminating the need for additional plate members in the seating space, thus maintaining a slim profile and enhancing mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If multiple plate members are used to support the flexible display panel, then the structural stability is improved, but the thickness increases and mobility deteriorates
Solution Approach 1:
The patent replaces traditional rigid plate members with a flexible circuit board that has bending resistance. This flexible circuit board maintains structural stability while being thin and flexible enough to allow the display to be folded without adding significant thickness, thereby resolving the contradiction between stability and thickness.
Solution Approach 2:
The patent introduces a hinge mechanism that allows the display to dynamically transition between folded and unfolded states. The hinge includes a hinge axis and hinge arm that enable controlled movement, providing structural stability when needed while allowing mobility when required, thus resolving the contradiction between stability and mobility.
2Strength
If multiple plate members are used to support the flexible display panel, then the structural strength is improved, but the device complexity increases
Solution Approach 1:
The patent combines the support function and the connection function into a single hinge mechanism. The hinge arm serves both as a structural support element and as a connection element that attaches the flexible circuit board to the housing, thereby reducing the number of separate components and simplifying the overall device structure while maintaining structural strength.
Solution Approach 2:
The hinge mechanism serves multiple functions: it provides structural support, enables folding movement, and connects the flexible circuit board to the housing. This multi-functionality reduces the need for separate components, thereby reducing device complexity while maintaining the required structural strength.
3Ease of operation
If the flexible display panel is folded into S-shape, then the mobility is improved, but the manufacturing precision requirement increases
Solution Approach 1:
The patent introduces a hinge mechanism as an intermediary between the flexible circuit board and the housing. The hinge provides a defined folding axis and controlled movement, which guides the folding process and reduces the precision requirements for the flexible circuit board itself. The hinge acts as a mediator that manages the complexity of the folding action.
