Solar Panel Clamp Fixing Through Slotted Rack Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional panel fixing devices for solar modules on roofs have poor workability due to the need to insert and slide them from the end of a rack member, making mounting and replacement inefficient.
Innovation Solution
A panel fixing device comprising a pressing tool, a fixing tool, and a fastening member that allows the fixing tool to be inserted from an opening in the rack member, rotated, and connected to the pressing tool to securely fix the panel without sliding along the rack member, enhancing workability by enabling diagonal insertion and rotation for easier installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fixing device is inserted from the end of the rack member and slid to the fixing position, then the panel can be fixed on the rack member, but the workability of mounting and replacing the panel deteriorates
Solution Approach 1:
Instead of inserting the fixing device from the end of the rack member and sliding it along the rack (conventional method), the invention allows insertion from any position through the opening portion of the rack member. This inverts the insertion direction and location, enabling the fixing device to be positioned directly at the desired location without sliding, thereby improving workability while maintaining fixing capability
Solution Approach 2:
The invention changes the insertion dimension from linear sliding along the rack member's length to direct insertion through the opening portion. By allowing the fixing device to be inserted from any position along the rack member through its opening, the system transitions from one-dimensional sliding insertion to multi-dimensional positioning insertion, significantly improving mounting efficiency
2Reliability
If the fixing device is inserted from the end of the rack member, then the panel can be fixed, but the complexity and effort required for installation increases
Solution Approach 1:
The rack member is pre-designed with an opening portion that allows direct insertion of the fixing device from any position. This preliminary structural preparation eliminates the need for complex insertion procedures from the end of the rack, reducing installation complexity while ensuring reliable fixing capability
Solution Approach 2:
The invention inverts the conventional insertion approach by allowing the fixing device to be inserted through the opening portion of the rack member from any position rather than from the end. This reversal simplifies the installation process by eliminating the need for long-distance sliding and complex positioning maneuvers

AI summary
A fixing device (1) according to a present invention includes a pressing tool (10) that abuts a part of a peripheral portion of a panel that is arranged on an upper surface portion of a hollow rod-like rack member (200) that has on the upper surface portion a slit-like opening portion extending along a longitudinal direction, a fixing tool (20) that abuts a back surface of the upper surface portion, the fixing tool configured insertable to the opening portion, and having in one direction a width wider than a width in a direction orthogonal to a longitudinal direction of the opening portion, and a fastening member (30) that integrally fixes the pressing tool (10) and the fixing tool (20) that abut a part of the peripheral portion of the panel and the back surface of the upper surface portion of the rack member (200), respectively.
