Solution Overview
Problem
The fragility of screens in electronic devices, such as smartphones and smart watches, makes them prone to damage during use due to their low strength compositions.
Innovation Solution
An electronic device with an electro-deformable layer on its display unit, a detection unit to assess state parameters like pressure, orientation, or motion, and a processing unit that applies a predetermined current to increase the strength of the electro-deformable layer when the device is in a predetermined state, thereby enhancing its durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If glass panels or polymer layers are used for screens, then the display function is achieved, but the strength and damage resistance are insufficient
Solution Approach 1:
The patent applies voltage to change the physical state of the electro-deformable layer, transitioning it between soft and hard states. This parameter change (electrical field application) allows the screen material to dynamically adjust its mechanical properties, resolving the contradiction between maintaining display flexibility and achieving sufficient strength and damage resistance.
Solution Approach 2:
The patent makes the screen's mechanical properties dynamic rather than static. The electro-deformable layer can transition between soft and hard states based on applied voltage, allowing the screen to adapt its strength and flexibility according to operational needs, thus resolving the contradiction between inherent material limitations and required performance.
2Strength
If the electro-deformable layer strength is increased to prevent damage, then the screen protection is improved, but the flexibility and deformability may be reduced
Solution Approach 1:
The patent makes the electro-deformable layer's mechanical properties dynamic rather than static. By applying voltage, the layer transitions between soft (deformable) and hard (strong) states, allowing it to adapt its properties based on operational needs. This resolves the contradiction by enabling the same material to exhibit both high deformability and high strength at different times.
Solution Approach 2:
The patent uses electrical field application to change the physical state of the electro-deformable layer. This parameter change allows the material to transition between different mechanical states, maintaining both deformability and strength capabilities without compromising either property permanently.
