Solution Overview

Problem

Current solar panel recycling methods consume high thermal energy and cause environmental pollution, and existing conveyor systems fail to adjust to varying panel thicknesses, leading to incomplete crushing and increased operational time and cost.

Innovation Solution

A conveyor belt speed is dynamically regulated based on the thickness of the solar panel glass, using a sensing unit to adjust the speed to optimize crushing time, and a separating unit to separate glass from the solar cell module, facilitating recycling of materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If heat is used to reduce adhesion between surface glass and solar cell module, then the glass can be separated, but thermal energy consumption increases and environmental pollution occurs

Engineering Contradiction:
Improveseparation effectivenessVSAvoidthermal energy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent replaces the thermal separation system with a mechanical crushing system. The solar panel is conveyed through a crushing chamber where rotating blades or hammers mechanically break the adhesion between glass and solar cells, eliminating the need for high-temperature heating while achieving effective separation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the separation mechanism from thermal energy input to mechanical energy input. By adjusting operational parameters such as conveying speed, blade rotation speed, and crushing chamber configuration, the system achieves separation through controlled mechanical forces rather than thermal energy.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If conveyor belt speed is increased, then productivity improves, but crushing completeness decreases for thick glass panels

Engineering Contradiction:
Improveprocessing throughputVSAvoidcrushing completeness
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent implements a dynamic conveying speed control system that adjusts the belt speed based on real-time detection of glass thickness. Sensors measure the thickness of each solar panel before it enters the crushing chamber, and the control system automatically adjusts the conveying speed to optimize crushing effectiveness for each panel type while maintaining overall productivity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback control where sensors continuously monitor glass thickness and provide real-time data to the control unit. The control unit processes this information and adjusts the conveying speed accordingly, creating a closed-loop system that adapts to varying panel specifications to ensure complete crushing while maintaining efficient throughput.

Inventive Principle:
Principle #23Feedback

3Manufacturing precision

If conveying speed is slowed down for thick glass, then crushing completeness improves, but processing time increases

Engineering Contradiction:
Improvecrushing completenessVSAvoidprocessing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system dynamically adjusts conveying speed based on detected glass thickness. For thick glass panels requiring longer crushing time, the belt speed is reduced to allow adequate processing time. For thin glass panels, the belt speed is increased to maintain high throughput. This dynamic adjustment eliminates the time loss associated with uniformly slow processing while ensuring complete crushing for all panel types.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control system changes the conveying speed parameter in real-time based on glass thickness measurements. By optimizing the speed parameter for each panel type, the system achieves complete crushing for thick panels without unnecessarily slowing down the processing of thin panels, thereby minimizing overall processing time while maintaining crushing effectiveness.

Inventive Principle:
Principle #35Parameter changes
