Solar Module Holding Device with Opposing Stop Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solar module attachment systems on building roofs and facades face challenges in securely fastening solar modules, leading to potential lifting or instability, especially under wind forces and uneven surfaces.
Innovation Solution
A holding device with opposing surfaces and stop surfaces is designed to securely mount solar modules on a carrier, utilizing a base element and stop elements that can be plugged together, with deformable sections to create a secure surface profile, allowing for efficient and stable attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional clamping elements with web and head elements are used to secure solar modules, then the solar modules can be mounted to support profiles, but the modules remain vulnerable to lifting forces and instability under wind loads
Solution Approach 1:
The holding device is divided into two separate stop surfaces positioned on opposite sides of the solar module. Each stop surface independently restrains the module in opposite directions, creating a segmented restraint system that effectively counteracts lifting forces while maintaining structural simplicity
Solution Approach 2:
The holding device uses symmetric stop surfaces that mirror each other on opposite sides of the solar module. This copying approach creates balanced restraint forces that effectively counteract asymmetric wind loads and lifting forces without requiring complex asymmetric结构设计
2Area of stationary object
If solar modules are mounted with adequate spacing for stability, then the modules remain secure, but the area utilization is reduced
Solution Approach 1:
The holding device transitions from conventional single-side clamping to a dual-side restraint system. By positioning stop surfaces on both sides of the solar module, the device creates restraint forces in multiple dimensions, enabling closer module spacing while maintaining stability through balanced opposite-direction forces
3Adaptability or versatility
If holding devices are designed to accommodate various roof types, then the system becomes versatile, but the device complexity increases
Solution Approach 1:
The holding device uses universal stop surfaces that can function on various roof types including flat and pitched roofs. The simple opposing stop surface design provides adaptive restraint without requiring roof-specific configurations, achieving multi-functionality through geometric simplicity rather than complex adaptation mechanisms
