Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solar panel recycling methods consume excessive thermal energy and cause environmental pollution, as they fail to efficiently manage the crushing process based on the varying thickness of the glass, often resulting in incomplete separation of the glass from the solar cell module.
Innovation Solution
A solar panel recycling system that dynamically regulates the conveyor belt speed of a crushing machine based on the thickness of the glass, using a sensing unit and control unit to adjust the crushing time, and includes a separating unit to effectively separate the glass and solar cell module for further recycling, reducing energy consumption and pollution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thermal energy is used to reduce adhesion between glass and solar cell module, then separation is achieved, but energy consumption increases and environmental pollution occurs
Solution Approach 1:
The patent replaces the thermal energy-based separation method with a mechanical crushing system. The solar panel is conveyed through a crushing chamber where mechanical force breaks the adhesion between glass and solar cell module, achieving separation without thermal energy input. This substitution eliminates the environmental pollution and high energy consumption associated with thermal methods.
2Reliability
If crushing time is increased to ensure complete glass crushing, then separation quality improves, but processing efficiency decreases
Solution Approach 1:
The patent implements dynamic speed regulation of the conveyor belt based on real-time glass thickness measurements. When thick glass is detected, the conveyor speed is reduced to extend crushing time and ensure complete fragmentation. When thin glass is detected, the conveyor speed is increased to maintain high processing efficiency. This dynamic adjustment optimizes the balance between crushing completeness and processing throughput.
Solution Approach 2:
The system incorporates a feedback mechanism where the sensing unit continuously measures glass thickness and provides real-time information to the control unit. The control unit adjusts the conveyor belt speed accordingly, creating a closed-loop control system that automatically optimizes crushing time based on actual material properties, ensuring both complete crushing and efficient processing.
3Manufacturing precision
If conveyor speed is reduced to increase crushing time, then glass separation quality improves, but overall system productivity decreases
Solution Approach 1:
The conveyor belt speed is dynamically adjusted based on measured glass thickness rather than operating at a constant reduced speed. This allows the system to maintain high throughput for thin glass while providing extended crushing time only when thick glass is detected, thereby improving separation quality without significantly compromising overall system productivity.
Solution Approach 2:
The system changes the operational parameter (conveyor speed) based on the measured property (glass thickness). By varying the speed parameter in response to material characteristics, the system optimizes separation quality for each specific piece of glass while maintaining high average throughput across diverse material inputs.
4Device complexity
If glass thickness is not measured and default conveying speed is used, then system complexity is reduced, but crushing effectiveness varies and energy is wasted
Solution Approach 1:
The system incorporates a sensing unit that provides real-time feedback on glass thickness, enabling the control unit to adjust conveyor speed appropriately. This feedback mechanism ensures that crushing energy is used efficiently by matching the conveying speed to the actual material requirements, avoiding energy waste that would occur with a fixed default speed.
Solution Approach 2:
The system uses the measured glass thickness information to automatically regulate its own operating parameters without external intervention. The sensing unit and control unit work together to self-adjust the conveyor speed based on material properties, optimizing crushing effectiveness and energy efficiency autonomously.
