Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual separation of residual material from display panels is inefficient, prone to damaging the circuit layer, and poses a risk to workers, with high labor costs and low precision in force, angle, and position control.
Innovation Solution
A residual material separation device comprising a loading platform, a fixing portion, and a pressing portion with a buffer layer and a rotatable pressing member that applies a controlled pressing force to the substrate adjacent to the residual material, allowing it to fall off without damaging the circuit layer, featuring a buffer layer made of rubber or silica gel and an acute angle between the pressing member and the substrate for gentle force application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual separation of residual material is used, then labor flexibility is maintained, but work efficiency is low and finger injury risk is high
Solution Approach 1:
The patent replaces the manual mechanical system with an automated mechanical pressing system. A pressing portion with a pressing member applies controlled pressing forces to the residual material, substituting human hand operations with automated mechanical actions. This eliminates direct contact between workers and residual material, preventing finger injuries while significantly improving work efficiency through automated high-speed operation.
Solution Approach 2:
The pressing member acts as an intermediary between the control system and the residual material. It transfers and distributes the pressing force uniformly across the residual material surface, enabling precise control of the separation process. This intermediary mechanism allows for controlled force application that is neither too weak (ineffective separation) nor too strong (causing damage), resolving the contradiction between separation effectiveness and safety.
2Manufacturing precision
If manual separation is performed, then operational simplicity is maintained, but manufacturing precision deteriorates due to imprecise force and position control
Solution Approach 1:
The separation device is segmented into distinct functional modules: a loading platform for positioning display panels, a fixing portion for securing panels, and a pressing portion with independently controllable pressing members. Each module performs a specific function, allowing for precise control of the separation process while maintaining reasonable device complexity through modular design. The pressing members can be independently positioned and controlled to achieve precise separation.
Solution Approach 2:
The device enables precise control of separation parameters including pressing force magnitude, pressing position, and pressing duration. By adjusting these parameters, the system achieves high manufacturing precision in residual material separation. The pressing force can be controlled to be sufficient for separation but not excessive to damage the circuit layer, and the positioning system ensures accurate application at the correct location.
3Reliability
If stronger pressing force is applied to separate residual material, then separation effectiveness improves, but circuit layer damage risk increases
Solution Approach 1:
The pressing members are designed to apply pressing force locally and uniformly to the residual material surface. The pressing force is concentrated on the residual material rather than being distributed across the entire display panel, ensuring effective separation while protecting the circuit layer. The local application of force allows for high separation effectiveness without causing damage to surrounding areas.
Solution Approach 2:
The pressing member incorporates a buffer layer made of soft material that provides cushioning during the pressing operation. This buffer layer prevents excessive force from being transmitted to the circuit layer while still delivering sufficient pressure to separate the residual material. The cushioning effect acts as a protective measure beforehand, preventing damage before it can occur.
