Securing fixture for photovoltaic cell module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing securing fixtures for photovoltaic cell modules are ineffective in positioning and fixing modules on the upstream side, leading to reduced working efficiency and potential durability issues of the trestle due to water ingress when installed on flat or ground-based systems.
Innovation Solution
A securing fixture comprising a first frame member and a second frame member forming a corner portion, with an abutting part fixed to the trestle and a holding part that includes a protrusion to position and fix the photovoltaic cell module on the upstream side, preventing water ingress and enhancing working efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the securing fixture is installed on the downstream side to position and fix the photovoltaic cell module, then the module can be fixed securely, but rain water flows down into the trestle reducing its durability
Solution Approach 1:
The patent inverts the conventional installation position from downstream side to upstream side. The securing fixture is now installed on the upstream side, which prevents rain water from flowing down into the trestle while still maintaining secure fixation of the photovoltaic cell module through the corner portion structure
2Ease of manufacture
If the securing fixture is installed on the downstream side, then the existing configuration can be used, but the photovoltaic cell module cannot be positioned and fixed on the upstream side reducing working efficiency
Solution Approach 1:
The patent changes the installation position from downstream to upstream side. The corner portion structure enables the securing fixture to effectively position and fix the photovoltaic cell module on the upstream side, improving working efficiency while maintaining ease of installation through the simple corner portion configuration
3Reliability
If a securing fixture is arranged on the downstream side, then the module can be fixed, but rain water may flow down the securing fixture into the trestle
Solution Approach 1:
The patent inverts the position from downstream to upstream side. By installing the securing fixture on the upstream side, the structure naturally prevents rain water from flowing down into the trestle, thereby extending the trestle's service life while maintaining effective fixation capability
Solution Approach 2:
The corner portion structure acts as an intermediary element that achieves both fixation and water prevention functions. The corner portion's geometric structure naturally redirects rain water away from the trestle while providing secure attachment points for the photovoltaic cell module

AI summary
A securing fixture for a photovoltaic cell module that includes a first frame member that extends in a first direction; and a second frame member that extends in a second direction and is adjacent to the first frame member, the second direction being orthogonal to the first direction, the securing fixture being enclosed by a frame member having a corner portion formed by the first frame member and the second frame member. The securing fixture includes an abutting part that is fixed to a trestle and abuts on the trestle; and a holding part that holds the photovoltaic cell module, including a first protrusion that protrudes in a direction opposite to the abutting part, and abuts on an inner surface of the corner portion of the frame member, and a placing part on which the second frame member is placed.
