Solar Cell Module Securing Structure With Abutting Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solar cell module securing structures face challenges in securely fastening solar cell modules onto installation faces, particularly on inclined roofs, as the modules can shift and detach during the securing process, leading to difficulties in maintaining proper alignment and stability.
Innovation Solution
A solar cell module securing structure featuring frames with slits and a securing tool with extending portions that prevent movement in orthogonal and upward directions, ensuring stable alignment and secure fastening by engaging with the frames' slits and abutting surfaces, allowing for easy adjustment and high workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional securing structures with slits are used, then the securing tool can be easily positioned and adjusted along the slits, but the solar cell module moves and detaches during the securing process
Solution Approach 1:
The patent applies preliminary action by providing abutting surfaces on the frames that contact the solar cell panel before the securing tool is fully installed. These abutting surfaces preliminarily position and stabilize the solar cell module in the correct orientation and location, preventing movement during the subsequent securing operation. The abutting surfaces are positioned to engage the panel edges, ensuring the module remains stable throughout the fastening process.
2Productivity
If the securing tool is inserted into the slit from the lateral direction, then the solar cell modules can be secured in order in one direction, but the module may detach in the direction orthogonal to the slit extension
Solution Approach 1:
The patent applies preliminary anti-action by designing abutting surfaces that preemptively counteract potential detachment forces. The abutting surfaces are positioned to prevent movement in directions orthogonal to the slit extension before detachment can occur. By providing these preventive contact surfaces, the system counteracts the tendency of the module to detach during the sequential installation process, maintaining alignment stability throughout.
3Ease of operation
If only slits are used for positioning, then the securing tool can slide easily, but the securing strength may be insufficient
Solution Approach 1:
The patent merges multiple functions into a unified structure. The abutting surfaces are integrated with the frame members, combining the positioning function (providing contact surfaces) with the structural support function (increasing securing strength). This merging eliminates the need for separate positioning mechanisms, as the same frame structures that provide sliding guidance also provide stabilizing contact surfaces that enhance overall securing strength.

AI summary
Provided is a solar cell module securing structure in which a first extending portion of one securing tool is inserted into a slit of one of the adjacent solar cell modules and a second extending portion of the same securing tool is inserted into a slit of the other of the adjacent solar cell modules, lower abutting surfaces of both of the solar cell modules are installed on an upper surface portion of the same securing tool, a projecting portion projects from the upper surface portion under the second extending portion at the inner side relative to the lower abutting surface, and a distance between the projecting portion and an end of the second extending portion is set to be larger than a distance between a lower end of an opening edge of the slit and the lower abutting surface.
