Solar module bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solar module holders are not adequately stable to withstand the combined forces of snow load, wind, and temperature fluctuations over a long period, making them unsuitable for durable attachment to roofs.
Innovation Solution
A solar module holder design featuring a bracket section with multiple arms detachably connected to a base support, where the arms dissipate load evenly and prevent tilting, combined with sliding block connections and a U-shaped central area to encompass roof coverings, ensuring stability and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a single-arm bracket design is used, then the construction is simpler, but the stability and load-bearing capacity are insufficient to withstand snow load and wind forces
Solution Approach 1:
The bracket support is divided into multiple arms (at least two arms) that are detachably connected to the base support. Each arm independently bears a portion of the load from the solar module, distributing the stress and increasing overall load-bearing capacity while maintaining a relatively simple construction
2Stability of the object's composition
If the bracket is rigidly fixed to prevent any movement, then stability is improved, but the ability to compensate for thermal expansion and contraction is reduced
Solution Approach 1:
The connection between the arms and the base support is designed as a detachable connection rather than a rigid fixed connection. This allows the bracket to adapt to thermal expansion and contraction while maintaining stability during operation, and enables easy assembly and disassembly
3Strength
If multiple arms are used to distribute load, then load-bearing capacity increases, but the device complexity and manufacturing cost increase
Solution Approach 1:
The bracket support is segmented into multiple arms that can be detachably connected to the base support. This segmentation allows for simplified manufacturing of individual components that can be assembled together, reducing overall manufacturing complexity while improving load distribution capability
Solution Approach 2:
The arms are designed with a standardized detachable connection that can be universally applied to the base support and potentially different configurations. This multi-functionality simplifies manufacturing by using standardized components across different applications
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design provides enhanced stability and adaptability to temperature changes, allowing for secure and long-term attachment of solar modules to various roof types, effectively withstanding environmental forces.
Implementation Method 1
a plurality of arms prevent impermissible tilting of the bracket carrier, since the arms lying at a distance from one another create support points which lie at a distance from one another... the free ends of the arms are connected to the base support via sliding block connections
