Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing frame assemblies for solar modules on flat roofs require special profiles for fastening, which are not necessary over the entire module length or width and must be adapted to different module dimensions, leading to inefficiencies and increased complexity.
Innovation Solution
A frame assembly with flat, inclined frame sides and movably connected T-profile carrier elements that allow for length adjustment and flexible adaptation to various solar module dimensions, using simple profiles like angles or T-profiles, reducing material usage and eliminating the need for special profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If special profiles are used for fastening solar modules, then the fastening function is guaranteed, but the device complexity and material usage increase
Solution Approach 1:
The frame assembly is divided into separate functional components: simple frame sides (angle or U profiles) and separate carrier profile elements (T-profiles with box profile recesses). The carrier profile elements are only positioned at specific locations where fastening is needed, rather than requiring the entire frame to be a complex special profile. This segmentation allows simple profiles to be used for the frame structure while dedicated carrier elements provide the fastening function only where required.
Solution Approach 2:
The carrier profile elements serve multiple functions: they provide fastening points for solar modules, connect adjacent frame sides, and enable length adjustment of the frame assembly. The T-profile design with box profile recess accommodates both the frame side insertion and the fastening function. This multi-functionality eliminates the need for entirely different specialized profiles for each function.
2Adaptability or versatility
If frame assemblies are adapted to different solar module dimensions, then versatility is improved, but manufacturing complexity increases
Solution Approach 1:
The frame assembly incorporates movable and adjustable carrier profile elements that can be repositioned along the frame sides. The connection between carrier profile elements and frame sides allows for adjustment in position and orientation. This dynamic adjustability enables the same frame assembly design to accommodate different solar module dimensions without requiring custom-manufactured frames for each module size.
Solution Approach 2:
The frame assembly allows for parameter adjustments including the position of carrier profile elements, the effective length of frame sides (through movable connections), and the orientation of the assembly. These parameter changes enable adaptation to different module dimensions while maintaining the same basic frame structure and profile types, simplifying manufacturing.
3Reliability
If special profiles are used over the whole module length, then fastening is secured, but material usage increases by 50%
Solution Approach 1:
The fastening function is extracted from the continuous frame structure and concentrated into discrete carrier profile elements positioned only at necessary locations. Instead of using special profiles throughout the entire module length, the patent uses simple angle or U profiles for the frame and adds separate T-profile carrier elements only where fastening is required. This extraction reduces material usage while maintaining fastening security at critical points.
Solution Approach 2:
Rather than providing fastening capability along the entire length of the module (excessive action), the carrier profile elements are positioned only at specific points where fastening is actually needed (partial action). The T-profile elements with box profile recesses provide sufficient fastening security at these discrete locations without the material cost of continuous special profiling throughout the whole module length.
