Panel member securing structure and panel member securing tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing panel member securing tools for solar battery modules on roofs face challenges in height adjustment after installation and risk deformation due to load transmission through multiple components, leading to increased weight and cost.
Innovation Solution
A securing structure with a base member and a tool that includes a stand, a lower holder moving up and down along the stand, an upper holder, and a shaft with an external thread, where the shaft is restricted in the axial direction and the force of the bolt is transmitted directly to the base member, reducing loads on components and allowing height adjustment without detaching the panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bolt force is transmitted through multiple components (lower bracket, helical drive, tooth grooves, stanchion), then the panel member can be secured, but the components are at risk of deformation and damage due to loads
Solution Approach 1:
The patent extracts the load transmission path from the traditional multi-component chain and redirects it directly to the base member. The bolt force now acts directly on the base member without passing through the lower bracket, helical drive, tooth grooves, or stanchion, thereby eliminating the risk of deformation and damage to these components while maintaining securing reliability.
Solution Approach 2:
The base member serves as an intermediary that directly receives and bears the bolt force. By positioning the base member to directly support the panel member and receive the fastening force, it acts as a mediator that protects the other components from excessive loads while ensuring secure attachment.
2Strength
If the components are increased in thickness to increase mechanical strengths, then the risk of deformation is reduced, but the securing tool is increased in weight and cost
Solution Approach 1:
The patent removes the unnecessary load-bearing function from the securing tool components (lower bracket, helical drive, tooth grooves, stanchion) by redirecting the force transmission path to the base member. This extraction of the load-bearing function allows these components to be designed with reduced thickness, thereby decreasing the overall weight and cost of the securing tool while maintaining sufficient strength for their actual functions.
3Ease of operation
If the panel member is detached for height adjustment, then the height can be adjusted, but the construction efficiency is lowered
Solution Approach 1:
The patent implements preliminary action by providing adjustable spacers that can be pre-positioned between the base member and the panel member before final securing. This allows height adjustment to be performed during the initial installation process without requiring detachment later, thereby maintaining construction efficiency while achieving the desired height adjustment capability.
4Adaptability or versatility
If a single tool type is used for panels of varying heights, then cost-effectiveness is improved, but the tool must accommodate different heights
Solution Approach 1:
The patent applies dynamics by making the tool configuration adjustable through interchangeable spacers and adjustable bracket positions. The lower bracket can be positioned at different heights, and spacers of varying thicknesses can be used, allowing a single tool type to adapt to panels of different heights without requiring multiple specialized tool variants, thus improving cost-effectiveness while managing complexity through modular adjustability.

AI summary
A panel member securing tool includes a stand holding a shaft with an external thread in a state of restricting movement in the axial direction, a cylindrical portion through which the stand is inserted, a lower holder having installation surfaces extending to both sides outward from the cylindrical portion, a flat plate portion through which a bolt hole portion and a tool hole portion are formed, an upper holder having panel pressing portions extending to both sides outward from the flat plate portion, a bolt inserted through the bolt hole portion and screwed with a first threaded groove formed in the stand, a second threaded groove formed in the cylindrical portion screwed with the external thread, and a hole or a space formed in the stand on an extended line of a center axis of the shaft between a tool engaging portion of the shaft and the tool hole portion.
