Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual removal of junction boxes is performed using hand tools, then the removal process can be completed, but the process is labor-intensive, inconvenient, and may damage the glass cover
Solution Approach 1:
The patent replaces manual hand tools with an automated removing device that uses a cutting blade to precisely separate the junction box from the back plate. The device includes a removing seat with a cutting blade that moves along the back plate to cut the adhesive bonding the junction box, eliminating the need for manual prying with hand tools and preventing damage to the glass cover through controlled cutting action
Solution Approach 2:
The patent introduces a cutting blade as an intermediary tool between the removing device and the junction box. The cutting blade selectively cuts the adhesive bonding the junction box to the back plate, serving as a mediator that separates the junction box without directly contacting or damaging the glass cover, thus preventing harm while achieving removal
2Productivity
If automated removing device is used, then labor intensity is reduced and removal precision is improved, but device complexity increases
Solution Approach 1:
The removing device is segmented into distinct functional modules: a frame mechanism for support, a carriage mechanism for carrying the solar cell module, and a removing mechanism with seat regulating module, aligning and holding seat module, and removing driving module. This segmentation allows each module to perform its specific function independently, simplifying the overall design while maintaining automation and precision
Solution Approach 2:
The removing device integrates multiple functions into a single automated system: the carriage mechanism both carries and positions the solar cell module, while the removing mechanism simultaneously aligns, holds, and executes the cutting operation. This multi-functionality reduces the need for separate manual operations and tools, improving productivity despite the increased automation

AI summary
A removing device for removing a junction box from a solar cell module includes a carriage mechanism and a removing mechanism mounted on a frame mechanism. The removing mechanism includes a seat regulating module, an aligning and holding seat module and a removing seat which is moved by the seat regulating module toward a back plate of a solar panel unit, and a removing driving module which drives movement of the removing seat toward the junction box along the back plate of the solar panel unit so as to move a cutting edge of the removing sear into a juncture between the junction box and the back plate and remove the junction box. An automatic removing process is performed, and damage to the solar panel unit is prevented.
