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 the wind pressure force itself to drive the adjustment mechanism. When wind blows, the force directly pushes the beam to rotate around the hinge point, automatically adjusting the inclination angle without external control systems. The structure serves itself by converting the harmful wind force into a useful adjustment mechanism.
Solution Approach 2:
The patent replaces complex electronic control systems, sensors, motors, and power supplies with a pure mechanical solution. The hinge connection and wind pressure force substitute for electronic actuators, achieving automatic adjustment through mechanical means only, thereby reducing device complexity and cost.
2Device complexity
If manual adjustment-type photovoltaic supports are used, then the structure remains simple, but the photovoltaic component cannot rapidly and accurately respond to disasters in time
Solution Approach 1:
The support structure automatically responds to wind disasters without human intervention. The hinge connection and wind pressure force work together to automatically adjust the beam angle, enabling rapid response to environmental changes while maintaining structural simplicity.
Solution Approach 2:
The patent transforms the static fixed support into a dynamic adjustable structure. The hinge connection allows the beam to rotate dynamically in response to wind pressure, enabling real-time adaptation to changing environmental conditions while keeping the overall structure simple.
3Device complexity
If fixed-type photovoltaic supports are used, then the structure is simple and convenient to maintain, but the photovoltaic component cannot adjust the angle according to external environment
Solution Approach 1:
The patent converts the static fixed support into a dynamic structure that can adapt to environmental changes. The hinge connection enables the beam to rotate and adjust its inclination angle in response to wind pressure, providing adaptability while maintaining structural simplicity.
Solution Approach 2:
The support structure automatically adjusts itself in response to wind conditions without external control. The wind pressure force directly drives the hinge mechanism to change the beam angle, enabling environmental adaptability through self-service operation.
4Productivity
If axis tracking-type photovoltaic supports are used to adjust inclination angle in time, then the conversion efficiency is improved, but the cost becomes high and maintenance becomes difficult
Solution Approach 1:
The patent replaces expensive electronic control systems with a simple mechanical hinge mechanism. The wind pressure force directly drives the adjustment, eliminating the need for sensors, motors, and control electronics, thereby reducing cost and maintenance requirements while maintaining the ability to adjust for optimal efficiency.
Solution Approach 2:
The support structure automatically adjusts itself using wind pressure, eliminating the need for external power sources and control systems. This self-service mechanism reduces operational costs and maintenance requirements while enabling the photovoltaic component to maintain optimal angles for conversion efficiency.

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.
