Magnetic Parking Arm Anchoring for Solar Cleaner Wind Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solar panel cleaning systems face challenges in maintaining stability and preventing damage during high wind conditions, as autonomous robotic cleaners (ARCs) may fall off or be dislodged from solar panels, leading to potential damage to the panels or surrounding areas.
Innovation Solution
A system with an anchoring mechanism for ARCs, featuring a magnetic parking arm that can engage and disengage with ferromagnetic docking or parking stations, ensuring the ARC remains firmly coupled even in harsh weather conditions, using a strong magnetic coupling and wireless communication with a weather information station to determine when to anchor and park.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the weight of an ARC is increased to improve stability on solar panels and resistance to wind, then stability and wind resistance are improved, but the risk of cracking or damaging the solar panel surface increases
Solution Approach 1:
The anchoring mechanism is divided into separate components: a magnetic anchoring system with parking arms that can engage with ferromagnetic anchors on the panel, and a supporting structure with wheels. This segmentation allows the ARC to use magnetic force for stabilization without requiring increased weight that would damage the panel surface.
Solution Approach 2:
The patent replaces the mechanical weight-based stabilization system with a magnetic anchoring system. Instead of relying on the ARC's weight to prevent being blown away, ferromagnetic anchors embedded in the panel interact with magnetic parking arms on the ARC, providing wind resistance through magnetic attraction rather than gravitational force.
2Reliability
If a magnetic anchoring system is used to prevent ARC dislodgement in high wind, then wind resistance and stability are improved, but the device complexity increases due to additional anchoring components
Solution Approach 1:
The magnetic anchoring system serves multiple functions: it provides wind resistance during cleaning operations, enables secure parking at docking stations, and facilitates precise positioning. The ferromagnetic anchors are embedded in the panel structure, serving both as structural elements and anchoring points, reducing the need for separate anchoring components.
Solution Approach 2:
The ARC's own weight and structure contribute to the anchoring system. The ferromagnetic material in the ARC's base interacts with the anchors, and the ARC's weight provides additional downward force that enhances magnetic engagement. The system uses the ARC's existing properties rather than requiring entirely separate anchoring mechanisms.
3Ease of manufacture
If the ARC is made lighter to reduce production costs and avoid surface damage, then cost effectiveness and surface safety are improved, but the ARC may fall off or be blown over more easily in high wind conditions
Solution Approach 1:
The patent replaces weight-based wind resistance with a magnetic anchoring system. The ferromagnetic anchors and magnetic parking arms create a magnetic attraction force that provides wind resistance independent of the ARC's weight, allowing lightweight construction while maintaining reliability in high wind conditions.
Solution Approach 2:
The system changes the physical parameter used for stabilization from mass (weight) to magnetic field strength. By using ferromagnetic materials and magnetic actuators, the ARC achieves wind resistance through magnetic force rather than gravitational force, enabling lighter construction without sacrificing reliability.
