Solution Overview
Problem
Existing photovoltaic supports fail to automatically adjust the angle of photovoltaic components according to external environmental conditions, such as wind intensity, and are often costly and complex, making them difficult to maintain and apply extensively.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If axis tracking-type photovoltaic supports are used to automatically adjust the inclination angle according to external environment, then the photovoltaic component can be adjusted in time, but the structure becomes complicated and the cost increases
Solution Approach 1:
The photovoltaic support structure uses wind pressure itself as the driving force to trigger automatic adjustment. When wind blows against the support, the wind pressure directly acts on the movable connecting pieces to change the inclination angle, eliminating the need for external sensors, motors, or control systems. The system serves itself by using the environmental factor (wind) that needs to be responded to as the actuating mechanism.
Solution Approach 2:
The patent replaces complex electromechanical tracking systems with a pure mechanical passive response mechanism. Instead of using motors, sensors, and control electronics to detect wind and adjust the angle, the design uses wind pressure directly acting on mechanical elements (movable connecting pieces, springs, dampers) to automatically change the inclination angle through mechanical means alone.
2Device complexity
If fixed-type photovoltaic support is used, then the structure is simple and maintenance is convenient, but the photovoltaic component cannot be adjusted and is easily damaged in bad weather
Solution Approach 1:
The patent transforms the fixed support structure into a dynamic one that can automatically adapt to changing wind conditions. The movable connecting pieces allow the support structure to change its configuration in response to wind pressure, enabling the photovoltaic component to adjust its inclination angle dynamically rather than remaining fixed, thus improving damage resistance while maintaining structural simplicity.
Solution Approach 2:
The support structure changes its geometric parameter (inclination angle) in response to wind conditions. By allowing the inclination angle to vary dynamically through the movable connecting pieces rather than remaining fixed, the system improves its ability to withstand bad weather while keeping the overall structure simple and easy to maintain.
3Device complexity
If manual adjustment-type photovoltaic support is used, then the structure is simple, but it is limited by human factors and cannot rapidly and accurately respond to disasters
Solution Approach 1:
The system eliminates human intervention by using wind pressure itself to trigger and drive the adjustment mechanism. When wind blows against the support, the wind pressure automatically acts on the movable connecting pieces to change the inclination angle, enabling rapid response without waiting for human detection and manual operation.
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated mechanical response system driven by wind pressure. Instead of requiring human operators to detect wind conditions and manually adjust the support, the design uses wind pressure directly acting on mechanical elements to automatically and rapidly change the inclination angle through pure mechanical means.

AI summary
A photovoltaic support includes a first vertical upright column (110) and a second vertical upright column (120) on a foundation, and a beam (10) respectively hinged with a first end of the first vertical upright column (110) and a first end of the second vertical upright column (120). The photovoltaic support further includes a first movable connecting piece (140) provided on the foundation and connected with a second end of the first vertical upright column (110). The first movable connecting piece (140) is automatically adjusted according to the wind intensity, such that the first vertical upright column (110) moves in a vertical direction to adjust an inclination angle of the beam (130). The photovoltaic support can adjust the angle adaptively in the case of a strong wind, and restore automatically after the strong wind has passed. The photovoltaic support has a simple structure and is convenient to maintain, does not require manual adjustment or a complex electrical control system, and solves the problems in which a related photovoltaic support fails to automatically adjust the angle of a photovoltaic component and recover automatically and has high costs.
