Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If known mounting systems are used, then structural stability is achieved, but device complexity increases due to numerous components
Solution Approach 1:
The patent combines multiple separate components (coupling element, locking element, and profile) into an integrated mounting system where the coupling element and locking element work together as a unified attachment mechanism. This merging reduces the number of separate parts while maintaining structural stability through the coordinated action of the clamping coupling element and the locking element with positioning section.
Solution Approach 2:
The mounting system is designed with universal applicability through the profile that can accommodate different module sizes and roof types. The coupling element with its clamping design and the locking element with positioning section create a multi-functional system that can be adapted to various installation conditions without requiring specialized components for each module type.
2Stability of the object's composition
If known mounting systems are used, then mounting stability is achieved, but quantity of components increases
Solution Approach 1:
The patent merges the coupling and locking functions into a coordinated system with fewer components. The coupling element encompasses the frame element while the locking element provides securing, replacing the need for multiple separate fastening components in traditional systems.
Solution Approach 2:
The system segments the mounting function into three key components: the profile for structural support, the coupling element for frame attachment, and the locking element for securing. This segmentation allows each component to perform its specific function efficiently while reducing the total quantity of components compared to integrated multi-component systems.
3Stability of the object's composition
If known mounting systems are used, then structural stability is achieved, but adaptability to different module types decreases
Solution Approach 1:
The profile and coupling element are designed with universal characteristics that allow them to work with framed photovoltaic modules of various dimensions and designs. The clamping coupling element can accommodate different frame sizes, and the locking element with its positioning section can adapt to different installation conditions, providing both structural stability and versatility.
4Reliability
If known mounting systems are used, then mounting security is achieved, but ease of operation decreases due to installation complexity
Solution Approach 1:
The coupling element is designed to be pre-assembled with the profile before module installation. This preliminary assembly simplifies the installation process by reducing the number of steps required during mounting, while the locking element ensures secure attachment once installed.
5Stability of the object's composition
If known mounting systems are used, then structural stability is achieved, but loss of time increases due to time-consuming installation
Solution Approach 1:
The profile and coupling element are pre-assembled before module installation, which significantly reduces on-site installation time. The locking element is designed for quick engagement, allowing rapid securing of modules while maintaining structural stability.
Solution Approach 2:
The segmented design with distinct profile, coupling element, and locking element allows for efficient assembly sequences that reduce installation time while ensuring each component is properly secured for structural stability.
6Stability of the object's composition
If known mounting systems are used, then mounting stability is achieved, but object-generated harmful factors increase due to damage to roof covering
Solution Approach 1:
The profile acts as an intermediary between the mounting system and the roof structure, distributing loads and preventing direct contact that could damage the roof covering. The coupling element with its clamping design provides secure attachment without requiring invasive modifications to the existing roof.
