Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sweeping devices for photovoltaic panels are costly and complex, with low efficiency due to reliance on manual sweeping and lack of effective automated solutions for small-scale power stations, which affects power generation efficiency and requires a simpler and more affordable automated cleaning method.
Innovation Solution
A sweeping device with a guide rail mechanism and multiple scraper mechanisms driven by a pull rope system, allowing for efficient cleaning of photovoltaic panel arrays with a simple structure and low cost, utilizing a pull rope component connected to a driving mechanism that moves scraper mechanisms along the guide rails to cover the entire panel surface.

Engineering Contradiction Analysis
1Extent of automation
If a conventional sweeping robot is used to automate photovoltaic panel cleaning, then automation level and cleaning efficiency are improved, but device complexity and cost increase significantly
Solution Approach 1:
The system divides the cleaning task into multiple independent scraper mechanisms (first scraper mechanism, second scraper mechanism, etc.), each responsible for specific panels. This segmentation allows automation while keeping each individual scraper mechanism simple in structure, avoiding the need for a single complex robotic system.
Solution Approach 2:
Multiple scraper mechanisms share common components including the guide rail mechanism, driving mechanism, and control system. This multi-functionality approach reduces overall system complexity by reusing standardized components across different cleaning units rather than designing unique systems for each panel.
2Device complexity
If manual sweeping is used to reduce device complexity and cost, then device complexity and cost are reduced, but cleaning efficiency and power generation efficiency deteriorate
Solution Approach 1:
The system merges multiple scraper mechanisms into a coordinated system that operates simultaneously on multiple panels. The control mechanism coordinates all scrapers to work together, achieving high cleaning efficiency comparable to advanced robots while maintaining simple individual component designs that keep overall system complexity low.
Solution Approach 2:
The scraper mechanisms are designed to automatically clean the photovoltaic panels without requiring manual intervention during operation. The driving mechanism automatically moves scrapers along guide rails to contact and clean panel surfaces, providing self-service automation that improves efficiency while keeping the system simple and affordable.
3Device complexity
If a single scraper mechanism is used to simplify the device structure, then device complexity is reduced, but cleaning capacity and productivity deteriorate due to inability to clean multiple panels simultaneously
Solution Approach 1:
The cleaning system is segmented into multiple independent scraper mechanisms, each capable of cleaning specific photovoltaic panels. This segmentation enables simultaneous cleaning of multiple panels, significantly increasing overall cleaning capacity while keeping each individual scraper mechanism simple and easy to manufacture.
Solution Approach 2:
The system transitions from a single-point cleaning approach to a multi-point parallel cleaning approach by deploying multiple scrapers across different panels simultaneously. This dimensional expansion in the cleaning system architecture increases productivity without proportionally increasing complexity, as each added scraper uses the same simple design template.
