Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing curved surface modules require a fixation mechanism at one side of the backlight source, resulting in a thick design that prevents the creation of a thin curved surface module while achieving curved-surface display.
Innovation Solution
A curved surface module design that uses mold frames and metallic frames on both sides of the backlight source, with bending mechanisms and fasteners to curve the display panel without the need for a fixation mechanism at the backlight source, allowing for a thinner profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a fixation mechanism (metallic frame or curved bracket) is provided at one side of the backlight source, then the curved surface module can achieve curved-surface display, but the thickness of the module increases
Solution Approach 1:
The patent divides the curvature application into two independent sides: one side uses a metallic frame with a bending mechanism, while the other side uses a curved bracket. This segmentation allows each side to be optimized independently, with the bending mechanism providing curvature without requiring the additional thickness that would result from using fixation mechanisms on both sides or using a single thick fixation structure.
Solution Approach 2:
Instead of using a fixation mechanism to force the display panel into curvature, the patent uses a bending mechanism that applies controlled force to create the desired curved shape. The bending mechanism in the metallic frame on one side works in conjunction with the curved bracket on the other side to achieve the curved surface display while maintaining a thin profile.
2Shape
If a fixation mechanism is provided at one side of the backlight source, then the display panel can be curved, but the overall device complexity increases due to the required fixation structure
Solution Approach 1:
The patent merges the curvature function into the metallic frame structure itself through the bending mechanism, rather than requiring a separate fixation mechanism. The metallic frame on one side and the curved bracket on the other side work together as an integrated system to achieve the curved display panel, reducing overall device complexity.
3Length of stationary object
If mold frames are secured on both sides of the backlight source with bending mechanisms, then the module thickness is reduced, but the manufacturing complexity increases
Solution Approach 1:
The patent segments the curvature application into two independent mold frames secured on opposite sides of the backlight source. Each mold frame has its own bending mechanism that can be independently adjusted and assembled. This segmentation simplifies the manufacturing process compared to using a single complex fixation mechanism, as each side can be manufactured and tested separately before final assembly.
Solution Approach 2:
The bending mechanisms in the mold frames are designed to be adjustable and dynamic, allowing for fine-tuning of the curvature during assembly. This dynamic capability simplifies manufacturing by enabling post-assembly adjustments rather than requiring precise pre-manufacturing of fixed curvature structures.

Function Achieved in This Case
Enables the creation of a thin curved surface module that achieves curved-surface display by applying force through bending mechanisms, reducing the overall thickness and enhancing display capabilities.
Implementation Method 1
the first fastener is configured to press the second metallic frame against the second mold frame, so as to apply a force by the bending mechanism of the second metallic frame onto the display panel, thereby to enable a middle portion of the display panel to be curved
