PV Module Frame Dismantling Device to Reduce Internal Component Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for dismantling PV module frames often cause damage to internal components due to improper force control, leading to scratches, cracks, or breakages, which complicates recycling and reduces the quality of recovered materials.
Innovation Solution
A dismantling device with a connection portion, first holding portion, and second holding portion that clamps and deforms the frame, allowing for gradual separation without striking or cutting, thus minimizing impact and damage to internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hammer is used to knock the frame off, then the frame can be removed, but backsheet scratches, cracks or breakages on glass plate and cells occur due to improper force control
Solution Approach 1:
The patent introduces a specialized dismantling device as an intermediary tool between the operator and the PV module frame. This device includes holding portions that grip the frame and a pushing portion that applies controlled force to separate the frame from the module, preventing direct impact from tools like hammers and eliminating the need for force control by the operator
Solution Approach 2:
The patent replaces the uncontrolled mechanical impact method (hammer knocking) with a controlled mechanical system that uses levers and holding portions to apply gradual, distributed force. The pushing portion acts as a lever to amplify and control the separating force, substituting the random impact mechanism with a controlled mechanical advantage system
2Productivity
If saw is used to cut the frame into smaller sections, then the frame can be removed, but backsheet scratches, cracks or breakages on glass plate and cells occur due to improper force control
Solution Approach 1:
The dismantling device serves as an intermediary that eliminates the need for cutting tools like saws. The holding portions grip the frame while the pushing portion provides controlled separation force, allowing complete frame removal without cutting and without causing damage to internal components
3Ease of operation
If force is applied to remove the frame, then the frame can be separated from the module, but internal components may be damaged
Solution Approach 1:
The dismantling device segments the force application process into distinct functional components: holding portions that grip the frame separately from the pushing portion that applies separation force. This segmentation allows independent optimization of each function - secure gripping and controlled force application - preventing damage to the laminated structure
Solution Approach 2:
The patent changes the parameters of force application by using a lever mechanism (pushing portion) that transforms and distributes the separating force. This converts concentrated, potentially damaging force into distributed, controlled force that maintains the integrity of the laminated structure while achieving frame separation
Applied Scientific Principles
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 device enables effective and damage-free removal of PV module frames, enhancing the recovery and recycling rate of valuable materials by evenly distributing force and preventing backsheet scratches or breakages.
Implementation Method 1
The second holding portion is configured to press against the other one of the inner wall and the outer wall so as to clamp the frame with the first holding portion and to distort the frame

AI summary
The disclosed embodiments relate to a dismantling device configured for a frame of a PV module. The dismantling device includes a connection portion, a first holding portion, and a second holding portion. The first holding portion is connected to the connection portion and configured to press against one of an inner wall and outer wall of the frame. The second holding portion is slidably disposed on the connection portion and movably closer to or away from the first holding portion along a sliding direction. The second holding portion is configured to press against the other one of the inner wall and the outer wall so as to clamp the frame with the first holding portion and to distort the frame.
