Solution Overview
Problem
Current single-point drive mechanisms in solar tracking systems are prone to twisting and resonance under strong winds, leading to deformation and damage, and are unable to achieve multi-point locking, which limits their wind resistance and stability.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If single-point drive mechanism is used, then device complexity is reduced, but wind resistance and stability deteriorate due to free long cantilever twisting and resonance
Solution Approach 1:
The patent divides the single drive point into multiple drive points distributed along the cantilever structure. Each drive point is equipped with its own drive mechanism, segmenting the long cantilever into shorter segments with fixed locking points. This segmentation prevents the formation of a free long cantilever, thereby eliminating twisting and resonance issues while maintaining reasonable device complexity.
2Reliability
If multi-point locking is implemented, then wind resistance and stability are improved, but device complexity increases due to additional drive mechanisms
Solution Approach 1:
The patent merges multiple drive mechanisms into a coordinated system where multiple drive points work together to achieve synchronous locking. By combining the functions of multiple drive mechanisms and coordinating their operation, the system achieves multi-point locking with enhanced wind resistance and stability while managing the complexity through integrated control.
3Device complexity
If single solar tracking system is used, then device complexity is reduced, but productivity is limited to only three 1500V photovoltaic strings
Solution Approach 1:
The patent designs the multi-point parallel synchronous drive device to serve multiple functions: it provides drive functionality for multiple photovoltaic strings simultaneously, enables multi-point locking for enhanced stability, and maintains a unified system architecture. This multi-functionality allows a single system to handle more than three 1500V photovoltaic strings while keeping device complexity manageable.
