Innovation Solution
A solar panel recycling and sorting machine with a crushing device and recycling device, featuring magnetic separators and conveyor belts, separates metal particles from fiberglass, allowing for the reuse of metals and preventing contamination, using air flow to transport particles and multiple magnetic selections to ensure purity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If physical crushing method is used to recycle solar panels, then the processing can be simplified, but the valuable resources become contaminated and mixing occurs
Solution Approach 1:
The patent applies preliminary action by using a picking device to separate metal particles from the solar panel before crushing. The device includes a picking plate with picking holes that selectively pick up metal particles through vibration and gravity, removing them ahead of the crushing process to prevent contamination of recycled materials
Solution Approach 2:
The patent applies segmentation by dividing the recycling process into distinct stages: preliminary metal particle removal, crushing, and screening. The picking device segments the metal particles from other materials before they enter the crusher, allowing each material type to be processed separately and maintaining purity
2Ease of operation
If entire solar modules are crushed and mixed before sorting, then the sorting process becomes easier, but the efficiency of resource recovery decreases
Solution Approach 1:
The picking device performs preliminary separation of metal particles before crushing, so that metals are removed in advance. This preliminary action increases resource recovery efficiency by ensuring metals are collected separately without being mixed with other materials during crushing
Solution Approach 2:
The patent applies extraction by removing metal particles from the solar panel assembly before the main crushing process. The picking plate extracts metal particles through selective picking, separating them from the rest of the panel materials to improve overall recovery efficiency
3Ease of manufacture
If traditional burial method is used for discarded solar panels, then the disposal is simple, but the environmental burden increases and costs rise
Solution Approach 1:
The patent applies discarding and recovering by collecting metal particles separately during the recycling process. The picked metal particles are deposited into a collecting device for reuse, transforming waste into recoverable resources and reducing environmental burden compared to traditional burial methods
Solution Approach 2:
The patent converts the harmful waste problem into a beneficial resource recovery opportunity. By separating and collecting metal particles before they become waste, the system transforms potential environmental pollution into reusable materials, turning a harmful disposal issue into a valuable resource stream
