Plate Module Securing Member to Prevent Rattling and Sliding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional securing members for plate-like modules, such as solar cell modules, face issues with rattling and sliding due to dimensional tolerance and lack of versatility, requiring specific modules with engaging portions for inclined installations, which complicates installation and increases costs.
Innovation Solution
A securing member design featuring an upper piece, a shaft portion, and a lower piece with an abutment portion and mounting hole, allowing the module to be securely sandwiched between the upper and lower pieces, supporting loads evenly and accommodating both inclined and flat installations without the need for engaging portions, thus enhancing versatility and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the frame body is inserted only between the base portion and to-be-bonded portion, then the securing member can be mounted on the module, but the module rattles and slides due to dimensional tolerance
Solution Approach 1:
The base portion is divided into two separate components: a U-shaped base body that provides lateral support, and a separate abutment portion that prevents sliding. This segmentation allows each component to perform its specific function effectively, eliminating rattling and sliding while maintaining ease of mounting.
Solution Approach 2:
The abutment portion acts as an intermediary element between the frame body and the mounting target. It provides an additional contact point that prevents the module from sliding, thereby enhancing stability without complicating the mounting process.
2Reliability
If a claw-like to-be-engaged portion is used to support load on inclined roofs, then the module can be secured on inclined surfaces, but the securing member lacks versatility when modules without engaging portions are used
Solution Approach 1:
The U-shaped base body serves multiple functions: it provides lateral support for modules with engaging portions, prevents sliding for modules without engaging portions, and maintains structural stability on both inclined and flat surfaces. This multi-functionality makes the securing member universally compatible with different module types.
Solution Approach 2:
Instead of relying on the module to provide engaging portions for load support, the invention inverts the approach by having the base portion itself provide the supporting structure through its U-shape configuration. This allows the securing member to support loads independently of whether the module has engaging portions.
3Reliability
If the base portion is enlarged to prevent sliding, then the module stability improves, but the mounting hole positioning becomes more complex
Solution Approach 1:
The base portion is segmented into a U-shaped base body and a separate abutment portion. This segmentation allows the mounting hole to be positioned simply on the base body without complicating the overall structure, while the abutment portion provides the necessary sliding prevention function.

AI summary
Provided is a securing member which can secure a plate-like module reliably and has high versatility. A securing member includes an upper piece that extends in a right-left direction, a shaft portion that extends downward from the upper piece, a lower piece that extends to both sides from a lower end of the shaft portion so as to be larger than the upper piece and has a curved bottom surface, and a mounting hole that penetrates through the lower piece at one side. The lower piece is mounted on a mounting target through the mounting hole in a state where a side surface of a plate-like module is made to substantially abut against the shaft portion so that the upper piece is lowered to abut against the upper surface of the plate-like module and the lower piece abuts against the lower surface of the plate-like module.
