Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple frame structure with transverse belts is used for the solar panel array, then the device complexity is reduced and ease of manufacture is improved, but the structural strength and resistance to wind stress deteriorate
Solution Approach 1:
The solar panel array structure is segmented into multiple functional components: parallel trusses for primary support, C-shaped transverse profiles for panel mounting, sliding profiles for adjustment, and reinforcement brackets for strengthening connections. This segmentation allows each component to be optimized independently while maintaining overall structural integrity and ease of assembly.
Solution Approach 2:
The structure employs composite construction combining different profile types (C-shaped profiles, square sliding profiles, tubular trusses) and connection methods (inverted U-clamps, tamper-proof screws, reinforcement brackets) to achieve both simplicity of assembly and high structural resistance to wind and weight stresses.
2Reliability
If reinforcement brackets and rings are added to the connection between the bushing and horizontal tube, then the strength and stability of the connection are improved, but the device complexity increases
Solution Approach 1:
Reinforcement brackets are pre-attached to the horizontal tube, and rings are pre-installed on the tube before assembling the bushing connection. This preliminary preparation ensures that when the bushing is mounted, the reinforcement elements are already in position to provide immediate structural support, reducing assembly complexity while maintaining high connection reliability.
Solution Approach 2:
The reinforcement strategy operates in multiple spatial dimensions: reinforcement brackets provide lateral strengthening, rings provide circumferential support, and the bushing provides central anchoring. This multi-dimensional reinforcement approach achieves high connection stability without requiring an overly complex single-dimension solution.
3Measurement precision
If linear actuators with electric motors are installed in the articulated connections for pivoting, then the measurement precision and control accuracy for solar tracking are improved, but the device complexity and cost increase
Solution Approach 1:
The patent replaces complex mechanical pivot control systems with linear actuators driven by electric motors. This substitution provides precise, programmable control of the pivoting assembly's inclination angle, enabling accurate solar tracking while simplifying the control mechanism compared to traditional mechanical systems with multiple linkages and manual adjustment points.
4Ease of operation
If sliding profiles with open grooves and tamper-proof screws are used to fasten panels, then the ease of operation and assembly are improved, but the manufacturing complexity of the profiles increases
Solution Approach 1:
The sliding profiles feature open grooves that allow panels to be slid into position dynamically during assembly, rather than requiring precise pre-alignment. The tamper-proof screws provide secure fastening while preventing unauthorized removal. This dynamic assembly approach simplifies installation while the profile geometry, though complex, can be manufactured using standard extrusion processes.
