Multi-Point Film Peeling for Curved Display Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a film is detached from a curved display panel, pressure is concentrated on one point, potentially causing damage.
Innovation Solution
A film peeling device with a frame module, elevator module, and holder modules that engage multiple points on the film to evenly distribute the peeling force, using a robot to move the device and control the peeling process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the film is separated from the display panel only in one direction, then the peeling process is simple, but pressure is concentrated on one point of the edge, causing damage to the display panel
Solution Approach 1:
The peeling device is divided into multiple holder modules (first holder module, second holder module, third holder module, fourth holder module) that are distributed at different positions around the display panel. Each holder module independently holds the film at a specific location, segmenting the peeling force into multiple application points rather than concentrating it at one location.
Solution Approach 2:
Multiple holder modules are combined with a common elevator mechanism that simultaneously controls the vertical movement of all holders. This merging allows the system to apply peeling force at multiple points while maintaining coordinated motion, distributing the pressure across the display panel edge rather than concentrating it at a single point.
2Object-affected harmful factors
If multiple holder modules are used to distribute peeling force, then damage to the display panel is prevented, but the device structure becomes more complex
Solution Approach 1:
The elevator mechanism serves as a universal component that controls multiple holder modules simultaneously. This single multi-functional element replaces what would otherwise require multiple independent actuation systems, reducing overall device complexity while maintaining the ability to distribute peeling force across multiple points.
Solution Approach 2:
The holder modules are arranged in a spatial distribution around the display panel (front, rear, left, right positions), utilizing spatial dimensionality to distribute forces. This spatial arrangement allows multiple holders to work independently at different locations while being controlled through a single vertical elevation dimension, simplifying the control architecture.
3Area of stationary object
If the wing frames are extended longer to reach more points on the film, then peeling coverage is improved, but the device size increases
Solution Approach 1:
The holder modules are nested within the wing frame structure, with each holder positioned at specific intervals along the wing spans. This nesting allows the device to achieve extended peeling coverage through the distributed holders while maintaining a compact overall structure, as the holders utilize the existing wing frame geometry rather than requiring additional extended structures.
