Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If thermal decomposition is used to dismantle solar cell modules, then the cover plate, solar cell panel, and back plate are separated, but the materials become contaminated and economic benefits are reduced
Solution Approach 1:
The dismantling process is divided into distinct stages: frame removal, back plate separation, and cell encapsulation laminate removal. Each stage uses specialized equipment to handle specific components, preventing cross-contamination and enabling separate recycling streams for each material type.
Solution Approach 2:
The patent replaces thermal decomposition (chemical process) with mechanical dismantling equipment including frame removal robots, back plate breaking devices, and cell encapsulation laminate removal apparatus. This mechanical approach preserves material purity while achieving complete separation of components.
2Productivity
If thermal decomposition is used to separate components, then materials are separated, but hydrofluorocarbons are produced polluting the environment
Solution Approach 1:
The patent eliminates thermal decomposition entirely by using mechanical systems for component separation. The frame removal robot, back plate breaking device, and laminate removal apparatus all operate mechanically, producing no harmful emissions while achieving complete component separation.
Solution Approach 2:
The patent converts the challenge of separating materials bound by adhesive layers into a benefit by using mechanical forces to cleanly separate components without chemical reactions. The frame removal and back plate breaking processes transform the bonding strength that previously required thermal decomposition into a manageable mechanical separation task.
3Productivity
If thermal decomposition is used for dismantling, then components are separated, but energy consumption is high and not economical
Solution Approach 1:
The patent replaces energy-intensive thermal decomposition with mechanical dismantling equipment that consumes significantly less energy. The frame removal robot uses controlled mechanical forces, the back plate breaking device uses targeted impact forces, and the laminate removal apparatus uses mechanical peeling actions, all of which are far more energy-efficient than heating the entire module to decomposition temperatures.
4Device complexity
If manual transportation and dismantling are used, then the process is simple, but labor time and costs are high
Solution Approach 1:
The dismantling system is designed to be self-sufficient, with automated equipment performing all dismantling operations without human intervention. The mobile platform autonomously positions itself, the robot removes frames, the breaking device separates back plates, and the laminate removal apparatus extracts solar cells, creating a self-service system that eliminates manual labor while maintaining process simplicity through modular design.
Solution Approach 2:
The patent employs dynamic, mobile dismantling equipment rather than fixed installations. The mobile platform can move to different module locations, the robot can adjust its positioning and gripping forces, and the breaking device can adapt its impact points, enabling flexible automated operation that reduces labor time while keeping the system relatively simple and adaptable.
5Productivity
If used solar cell modules are transported for recycling, then centralization is achieved, but transportation costs are high due to low value-to-weight ratio
Solution Approach 1:
Instead of transporting heavy solar modules to centralized recycling facilities, the patent inverts the approach by bringing the recycling equipment to the modules. The mobile dismantling platform travels to where modules are located (such as installation sites or storage areas) and performs on-site dismantling, eliminating transportation costs while maintaining centralized recycling capabilities through the mobile platform's structured process.
