Solar Module Mounting Crosspiece With Slidable Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional securing configurations for solar cell modules on roofs require precise alignment and a large number of crosspiece members, leading to increased installation costs and time, and are cumbersome due to the need for parallel cross formations, which complicates the installation process and compatibility with varying roof tile pitches.
Innovation Solution
A securing configuration that uses supporting members with plate-like pieces and crosspiece members with slidable fasteners, allowing the solar cell module to be secured at intersections, reducing the need for precise alignment and minimizing the number of parts required, while enabling installation on roofs with non-matching tile pitches and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mounting mount is formed in the form of parallel crosses using multiple crosspiece members, then the solar cell module can be securely mounted, but the number of parts increases and installation cost increases
Solution Approach 1:
The patent merges the functions of multiple crosspiece members into a single integrated crosspiece member. This single member includes multiple holding portions (first holding portions for first fastener members and second holding portions for second fastener members) that can secure the solar cell module at multiple points simultaneously, eliminating the need for multiple separate crosspiece members while maintaining mounting security
Solution Approach 2:
The single crosspiece member is designed with multi-functionality, serving as both a structural support element and a multi-point securing element. It incorporates multiple types of holding portions that can accommodate different fastening methods, allowing one component to perform the work of multiple components in conventional mounting systems
2Manufacturing precision
If the lateral crosspieces are mounted at an interval in accordance with the size of the solar cell module with high accuracy, then the solar cell module can be properly secured, but the installation work becomes troublesome and operation cost increases
Solution Approach 1:
The patent changes the parameter of crosspiece spacing from fixed precise intervals to flexible variable intervals. The single crosspiece member with multiple holding portions can be positioned at various intervals along the roof, and the holding portions can be activated selectively based on the solar cell module size and position, eliminating the need for high-precision interval control
Solution Approach 2:
The mounting system transitions from a static fixed-interval configuration to a dynamic adjustable configuration. The holding portions on the crosspiece member can be selectively engaged or disengaged, allowing the effective spacing and positioning to be adjusted during installation to match different solar cell module dimensions without requiring precise pre-calculation of interval positions
3Manufacturing precision
If the crosspiece members are mounted at an interval in accordance with the size of the solar cell module, then the solar cell module can be secured, but the work period is extended
Solution Approach 1:
The crosspiece member is pre-configured with multiple holding portions during manufacturing, so that during installation, the installer only needs to select and engage the appropriate holding portions rather than measuring and marking precise intervals on-site. This preliminary preparation of multiple engagement options eliminates time-consuming measurement and calculation steps during the actual installation process
4Adaptability or versatility
If supporting clasps are mounted on supporting tiles and the size of the solar cell module does not correspond to the laying pitch of the roof tiles, then the crosspiece members cannot be supported at the required interval, but the solar cell module cannot be installed on the roof member
Solution Approach 1:
The crosspiece member is designed as a universal component with multiple holding portions that can accommodate various solar cell module sizes and positions. This multi-functional design allows the same crosspiece member to be used regardless of the roof tile laying pitch, as the holding portions can be selectively engaged to match different module dimensions and positions, ensuring installation feasibility across different roof configurations

AI summary
A securing configuration of a solar cell module includes a plurality of supporting members which are mounted on roof members; a plurality of crosspiece members each of which is inserted between and supported by the supporting pieces of the plurality of supporting members, has first holding portions which hold first fastener members in a slidable manner on both side faces and a second holding portion which holds a second fastener member in a slidable manner on an upper face, and which are arranged at a predetermined interval in the roof lateral direction; and securing members which secure the solar cell module installed on the plurality of crosspiece members such that long sides of the solar cell module are intersected with the plurality of crosspiece members to the crosspiece members through the second fastener members held by the second holding portions.
