Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional mounting structures are used, then modules can be mounted on buildings, but space utilization is not maximized and installation is complex
Solution Approach 1:
The frame is divided into modular components including a base portion with mounting features, legs, and panel support portions. This segmentation allows for simplified assembly and maximizes space utilization by enabling precise positioning of modules on building surfaces.
Solution Approach 2:
The frame structure incorporates multiple functions: the base portion provides mounting attachment, the legs provide structural support and spacing, and the panel support portions secure the photovoltaic panels. This multi-functionality reduces the need for separate mounting structures, simplifying installation while maximizing space utilization.
2Reliability
If complex mounting structures are used, then secure attachment is achieved, but installation time increases and equipment requirements increase
Solution Approach 1:
The frame includes pre-configured mounting features such as mounting holes, attachment points, and integrated fastening mechanisms that are prepared in advance during manufacturing. This preliminary action eliminates the need for complex field assembly operations, reducing installation time while maintaining secure attachment.
Solution Approach 2:
The frame structure incorporates self-aligning and self-securing features that reduce the need for specialized installation equipment and complex procedures. The modular design allows for tool-free or minimal-tool assembly, enabling quick and secure mounting without extensive installation time.
3Ease of operation
If minimal equipment is used for installation, then installation simplicity is improved, but mounting precision may be compromised
Solution Approach 1:
The frame incorporates localized precision features at critical mounting points, such as pre-drilled holes with precise tolerances, integrated alignment features, and precision-machined attachment surfaces. These local quality enhancements ensure mounting precision is maintained at key locations while the overall structure remains simple to install with minimal equipment.

AI summary
A frame for a photovoltaic module may include: a base portion having an outer lip and a bottom surface while also defining an opening configured to receive a first mounting element therein; at least one leg extending from the base portion; and a panel support portion extending from the at least one leg and configured to secure a solar panel therein. The outer lip and the at least one leg may define a cavity.
