Innovation Solution
An integrated structure of a steel frame assembly and a steel support for a solar photovoltaic power station, featuring long-side and short-side steel frames connected through angle codes, with specific designs such as zero-gap folding edges, anti-rotating bumps, and D-shaped riveting points, and U-shaped purlines for secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If steel frames with sides A are used to connect photovoltaic modules, then the connection strength is improved, but dust accumulation on the photovoltaic module surface increases
Solution Approach 1:
The steel frame is divided into two types: steel frames with sides A (for connection strength) and steel frames without sides A (for dust prevention). By segmenting the frame structure into different configurations at different locations, the patent simultaneously achieves both strong connections and dust-free surfaces where needed.
Solution Approach 2:
Different parts of the steel frame structure are given different properties: some frames have sides A for connection strength, while others are designed without sides A to prevent dust accumulation. This local differentiation allows each part to optimize for its specific function.
2Ease of manufacture
If traditional mounting modes with ordinary hexagon bolts are used, then the assembly process is simple, but the mounting structure becomes unstable and easy to loose and fall
Solution Approach 1:
The patent introduces angle codes as intermediary components that mediate between the steel frames and photovoltaic modules. These angle codes provide specialized connection structures (with holes and positioning features) that enhance stability while maintaining assembly simplicity, acting as a bridge between the frame and module.
Solution Approach 2:
The angle codes are pre-designed with specific hole patterns and positioning features that enable stable connections. By preparing these connection elements in advance with optimized geometries, the system achieves both ease of assembly and mounting stability without requiring complex on-site adjustments.
3Ease of operation
If photovoltaic modules are assembled with traditional purlines, then the assembly process is straightforward, but the modules are easy to slide and positioning is unavailable
Solution Approach 1:
The patent replaces traditional friction-based or simple mechanical positioning systems with a more advanced mechanism involving angle codes with specific hole patterns and positioning features. This substitution provides positive mechanical interlocking through the angle code geometry, preventing sliding while maintaining assembly straightforwardness.
Solution Approach 2:
Angle codes serve as intermediary components between the purlines and photovoltaic modules, providing specialized positioning features and connection holes. These intermediaries enable accurate module positioning and prevent sliding, while the overall assembly process remains straightforward due to the standardized nature of the angle codes.
4Reliability
If steel frames are connected through angle codes with riveting point connection, then the connection is firm and reliable, but the mounting time increases and working progress slows down
Solution Approach 1:
The angle codes are pre-designed with optimized hole patterns and positioning features that enable rapid alignment and connection. By preparing these connection elements in advance with standardized geometries, the system achieves both reliable connections and improved mounting efficiency, reducing the time penalty associated with complex connections.
Solution Approach 2:
The patent optimizes the geometric parameters of the angle codes, such as hole diameter, hole pattern, and positioning feature dimensions, to balance connection reliability with mounting speed. By carefully selecting these parameters, the system achieves firm connections without excessive mounting time, improving overall productivity.
