Solar Cell Panel Securing Structure with Threaded Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solar cell panel securing structures face challenges in easy operation and fine height adjustment, particularly on uneven roof surfaces, where traditional methods require multiple operators and are not efficient for repeated installation and removal without compromising mechanical strength.
Innovation Solution
A solar cell panel securing structure featuring first frames with slits and securing tools with a movable holder and shaft, allowing for easy alignment and fine height adjustment of solar cell panels on various installation faces, including inclined roofs, by using a base member, stand, and holder with internal and external threads for precise positioning and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional securing tools are used to secure solar cell panels to installation faces, then the panels can be fixed in place, but the operation becomes complex and requires multiple operators when fine height adjustment is needed on uneven surfaces
Solution Approach 1:
The holder is designed to be movable relative to the stand along the shaft, allowing dynamic adjustment of the frame height. The holder can slide up and down the shaft and be fixed at any position using the locking member, enabling flexible adaptation to uneven installation surfaces without requiring complex multiple-operator coordination
Solution Approach 2:
The securing tool is divided into separate components: a base member, a stand, a holder, and a locking member. This segmentation allows independent adjustment of each component, particularly the holder's position on the shaft, facilitating easy height adjustment while maintaining overall system simplicity
2Adaptability or versatility
If solar cell panels are repeatedly detached and secured again, then panel exchange becomes possible, but the mechanical strength of the securing structure is lowered due to repeated hole boring
Solution Approach 1:
The base member with fastening members is designed to remain permanently secured to the installation face, while the stand and holder can be repeatedly detached and reattached. This allows panel exchange without re-boring holes in the installation face, preserving mechanical strength while enabling adaptability
Solution Approach 2:
The separable connection between the base member and stand, and between the stand and holder, enables dynamic reconfiguration. The stand can be detached from the holder to remove solar cell panels and reattached to secure new panels, allowing repeated operations without compromising the permanently fixed base member's strength
3Manufacturing precision
If spacers are used for height adjustment, then the height of solar cell panels can be changed, but fine adjustment is difficult and multiple operators are required
Solution Approach 1:
The holder can continuously slide along the shaft to achieve fine height adjustments at any position, rather than being limited to discrete spacer thickness increments. The locking member allows the holder to be fixed at any precise position along the shaft's length, enabling fine adjustment with a single operator
Solution Approach 2:
The height adjustment mechanism changes from discrete spacer thickness selection to continuous positional adjustment along the shaft. The holder's position can be varied continuously along the shaft's length, providing fine-grained height control without the limitations of fixed spacer dimensions
4Ease of manufacture
If securing tools are fixed at predetermined positions, then installation is simplified, but adaptation to uneven roof surfaces and repeated installation/removal is compromised
Solution Approach 1:
The holder's position on the shaft is made adjustable rather than fixed, allowing the frame height to be changed to adapt to uneven roof surfaces. The locking member enables the holder to be secured at any position along the shaft, combining ease of installation with adaptability to various installation conditions
Solution Approach 2:
The separable design of the securing tool components allows the holder and stand to be adjusted or replaced independently while keeping the base member fixed. This segmentation enables adaptation to different installation conditions without requiring complete reinstallation, simplifying both initial installation and subsequent modifications

AI summary
In a securing unit including first frames for holding the end sides of a solar cell and a securing tool, the securing tool includes a base member that is secured to an installation face, a stand that is erected from the base member, a shaft that has an external thread and is held by the stand in a state in which a movement in the axial direction is restricted, and a holder that holds the first frame by inserting a lateral side extended portion into a slit of the first frame and moves up and down relatively to the stand by screwing internal threads formed in the holder together with the external thread of the shaft.
