Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plate-shaped article disassembling technologies face inefficiencies due to the need to align the front and back surfaces and move electrodes or the article to change peeling positions, especially when recycling materials like solar battery panels with strongly bonded interlayers.
Innovation Solution
A pulsed discharge disassembling device with parallel electrodes in a liquid container, an insulating plate positioned below the discharge gap, and a pulsed power supply, allowing for efficient disassembly without aligning the article's surfaces or moving the electrodes, using a high-voltage pulse to induce shock waves for disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the discharge path is concentrated in one part, then the disassembly process is simplified, but the article may be excessively crushed locally and disassembly efficiency decreases
Solution Approach 1:
The patent introduces a third dimension by tilting the plate-shaped article at an angle of 45° or more relative to the discharge direction. This angular orientation causes the shock wave to propagate through the article in a distributed manner across multiple locations rather than concentrating force at a single point, thereby preventing excessive local crushing while maintaining process simplicity
Solution Approach 2:
The patent employs dynamic movement of the plate-shaped article between discharge pulses. The article is moved to different positions and/or rotated between successive discharges, ensuring that the concentrated discharge path affects different regions over time. This dynamic repositioning distributes the disassembly effect across the entire article while maintaining a fixed, simple discharge configuration
2Productivity
If the electrodes or article are moved to change peeling positions, then uniform disassembly is achieved, but the operation complexity and time increase
Solution Approach 1:
The patent makes the article dynamic by moving and/or rotating it between discharge pulses while keeping the electrodes stationary. This approach achieves uniform disassembly across different peeling positions without requiring complex electrode movement mechanisms, thereby maintaining ease of operation while improving disassembly uniformity
Solution Approach 2:
The patent uses periodic discharges with intervals between pulses, allowing the article to be repositioned or rotated during these intervals. This periodic action sequence (discharge → reposition → discharge) enables systematic coverage of different regions without requiring continuous complex positioning during the discharge itself
3Strength
If the discharge energy is increased to break strong bonds, then disassembly effectiveness improves, but the risk of excessive crushing and energy waste increases
Solution Approach 1:
The patent uses dynamic repositioning of the article between discharge pulses to distribute the high-energy discharges across multiple locations. This ensures that each discharge maintains high energy for effective bond breaking, while the overall energy is efficiently utilized across the entire article rather than being wasted on repeatedly crushing the same location
Solution Approach 2:
The patent segments the disassembly process into multiple discrete discharge pulses with intervals for repositioning. This segmentation allows the system to apply high energy in controlled bursts at different locations, breaking strong bonds effectively while avoiding energy waste from concentrated excessive force at any single point

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method enables efficient disassembly of plate-shaped articles by concentrating the discharge path, reducing local disassembly and excessive crushing, and eliminating the need to move the electrodes or article, thus improving recycling efficiency and energy savings.
Implementation Method 1
a pulsed power supply that applies a high voltage pulse between the positive electrode and the negative electrode
Implementation Method 2
By discharging by using coaxial electrode 201, part of jelly-like substance 203 is gasified or plasmatized by rapid joule heating. Then, since part of jelly-like substance 203 expands due to gasification or the like, pressure wave 210 is generated in jelly-like substance 203.
Implementation Method 3
part of jelly-like substance 203 is gasified or plasmatized by rapid joule heating
Implementation Method 4
pressure wave 210 is generated in jelly-like substance 203. This pressure wave 210 is incident on surface 204 of plate-shaped body 202 with jelly-like substance 203 as a medium.
