Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Curved-surface displays in notebook computers result in increased volume, thickness, and weight due to the need for an arc-shaped casing, leading to insufficient structural strength and operational inconvenience.
Innovation Solution
An electronic device featuring a first body and a second body with a magnetic force mechanism, allowing the flexible display to be magnetically attracted or repelled, enabling it to unfold or bend without a fixed curvature, thus allowing the casing to be designed for a thin and lightweight structure, and facilitating easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a curved-surface display screen with fixed curvature is installed in the casing, then the display provides surround field of vision and visual immersion effect, but the casing volume, thickness and weight increase
Solution Approach 1:
The patent applies the dynamics principle by making the display screen curvature adjustable rather than fixed. The display screen can dynamically change its bending radius between a first bending radius (providing surround field of vision) and a second bending radius (reducing casing volume). This allows the system to adapt between two distinct states, resolving the contradiction between visual immersion effect and compact size.
2Shape
If the casing is designed with arc shape to fit the curved-surface display screen, then the display curvature is maintained, but the casing thickness and weight increase
Solution Approach 1:
The casing design incorporates a movable support structure that enables the display screen to dynamically adjust its curvature. The support structure includes movable components that can change position to accommodate different bending radii, allowing the casing to maintain a lighter, more compact form while still supporting the curved display when needed.
3Shape
If the curved-surface display is closed to the machine body, then the display provides curved viewing experience, but large gap exists between the casing and the machine body
Solution Approach 1:
The patent employs a movable support mechanism that can adjust its position and orientation dynamically. When the curved display experience is desired, the support structure positions itself to maintain the curved configuration while minimizing gaps. The movable nature of the support allows it to adapt to different closure states, eliminating the need for large fixed gaps.
4Shape
If the casing is designed with arc structure to accommodate fixed curvature display, then the display curvature is fixed, but the overall thickness becomes overly great
Solution Approach 1:
The support structure is designed with movable components that can change position to accommodate different display curvature states. This dynamic support mechanism eliminates the need for a thick, fixed arc-shaped casing, as the support can adapt its geometry to match the display's current bending radius, thereby reducing overall casing thickness.
5Shape
If the casing is designed with arc structure for fixed curvature display, then the display maintains fixed curvature, but the structural strength becomes insufficient
Solution Approach 1:
The movable support structure can dynamically adjust its configuration to provide optimal structural support for the curved display. The support mechanism includes reinforcement elements that can be positioned to strengthen the casing structure where needed, while still allowing the display to maintain its curved shape. This dynamic reinforcement resolves the contradiction between maintaining display curvature and ensuring structural strength.

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 solution enables a thin and lightweight design, prevents excessive thickness and structural weakness, and enhances user convenience by allowing the flexible display to adjust curvature dynamically, while maintaining a close attachment of the second body to the first body, thus providing a surround field of vision for visual immersion.
Implementation Method 1
The magnetic force mechanism is magnetically coupled to the supporting mechanism, wherein the magnetic force mechanism generates a magnetic attraction force or a magnetic repulsion force to the supporting mechanism by the second body rotating relative to the first body
