Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices, particularly flexible ones, face challenges in being easily foldable and lightweight due to structural limitations.
Innovation Solution
A display device design incorporating a support plate with a flat and flexible portion, linked by bars, which can be folded and accommodated within a case, using plastic materials to reduce weight and enhance foldability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid support structure is used to maintain structural support, then strength is improved, but weight increases and foldability deteriorates
Solution Approach 1:
The support plate is divided into a flat portion and a flexible portion with distinct functions. The flat portion provides structural support while the flexible portion enables folding, allowing the structure to be segmented into support-functional and movement-functional zones that can operate independently.
Solution Approach 2:
Different regions of the support plate have different material properties: the flat portion uses a first material optimized for strength and support, while the flexible portion uses a second material optimized for flexibility and low elastic modulus, enabling each region to perform its specific function efficiently.
2Strength
If a rigid support structure is used to maintain structural support, then strength is improved, but ease of folding deteriorates
Solution Approach 1:
The support plate is divided into a flat portion and a flexible portion with distinct functions. The flat portion provides structural support while the flexible portion enables folding, allowing the structure to be segmented into support-functional and movement-functional zones that can operate independently.
Solution Approach 2:

3Weight of moving object
If plastic materials are used to reduce weight, then weight is reduced, but strength deteriorates
Solution Approach 1:
Different regions of the support plate have different material properties: the flat portion uses a first material optimized for strength and support, while the flexible portion uses a second material optimized for flexibility and low elastic modulus, enabling each region to perform its specific function efficiently.
Solution Approach 2:
The support plate uses composite construction with at least two different materials: a first material for the flat portion providing structural strength, and a second material for the flexible portion providing flexibility. This composite approach allows the structure to achieve both strength and flexibility requirements.
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 design allows for easy folding and accommodation of the display module, maintaining structural support while reducing weight by using non-metallic materials, facilitating both default and extended modes of operation.
Implementation Method 1
a flexible portion that extends from the flat portion and that is folded such that a portion is disposed under the flat portion, the flexible portion being folded about a folding axis extending in one direction
Implementation Method 2
the flexible portion having a lower elastic modulus than the flat portion
