Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple holders are produced for different frame geometries, then each holder is optimized for its specific geometry, but production complexity and costs increase
Solution Approach 1:
The holder is designed with a universal base plate and receiving elements that can accommodate multiple frame geometries through adjustable support surfaces. The support surfaces can be positioned at different locations and angles to match various frame configurations, allowing a single holder design to serve multiple functions for different solar module types.
Solution Approach 2:
The holder incorporates adjustable and movable support surfaces that can be repositioned to adapt to different frame geometries. This dynamic adjustment capability allows the holder to transform its configuration to match various solar module frame shapes, eliminating the need for multiple fixed holder variants.
2Adaptability or versatility
If multiple holders are produced for different frame geometries, then each holder fits its specific geometry precisely, but production costs and inventory requirements increase
Solution Approach 1:
The holder is designed with a universal base plate and receiving elements that can accommodate multiple frame geometries through adjustable support surfaces. The support surfaces can be positioned at different locations and angles to match various frame configurations, allowing a single holder design to serve multiple functions for different solar module types.
Solution Approach 2:
The holder is divided into modular components including the base plate, receiving elements, and adjustable support surfaces. This segmentation allows the support surfaces to be independently positioned and adjusted to accommodate different frame geometries, simplifying manufacturing while maintaining versatility.
3Reliability
If traditional mounting methods are used, then solar modules can be securely fixed, but mounting time and complexity increase
Solution Approach 1:
The holder features self-aligning receiving elements with slots that automatically guide the frame legs into the correct position during insertion. The inclined support surfaces automatically orient the solar module at the desired angle, eliminating the need for complex alignment procedures and reducing mounting time while maintaining secure fixation.
Solution Approach 2:
The holder is pre-configured with receiving elements and support surfaces positioned to automatically guide and secure the solar module frame. The slots and inclined surfaces are designed in advance to perform the alignment and positioning functions that would otherwise require manual adjustment during installation.
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
Enables the production and use of a single holder for multiple frame geometries, simplifying production and mounting, ensuring secure and stable solar module installation with reduced costs and effort.
Implementation Method 1
The proposed pointed protrusions serve to perforate a coat of paint or anodic coating or some other coating provided optionally on the leg, such that electrical contact is established between the holder and the frame. This allows undesired static charges to be conducted from the frame to ground via the holder.

AI summary
A holder for a solar module has a rectangular frame which has a peripheral side wall from at least one side of which there extends a leg that is directed toward the frame interior. The holder has a base plate with two receiving elements extending therefrom for receiving the leg. Each receiving element is assigned at least one support surface, attached to the base plate, for supporting the side wall, the spacing of said support surface from the receiving element being variable.
