Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional rotating mast with pivot mechanisms is used to orient solar panels, then panels can track sun movement, but the assembly thickness increases and wind resistance increases
Solution Approach 1:
The orientation system is divided into two independent rotational movements: azimuth rotation (horizontal tracking) and elevation adjustment (vertical angle). This segmentation allows each component to be optimized separately, with the elevation mechanism using a compact helicoidal link that minimizes thickness and wind exposure while maintaining full sun tracking capability.
Solution Approach 2:
The patent transitions from a single vertical mast structure to a two-dimensional rotational system where the panel assembly can rotate horizontally (azimuth) and adjust vertically (elevation) independently. This dimensional change allows the panels to track the sun's movement across the sky while keeping the support structure's thickness minimal, reducing wind resistance significantly.
2Ease of operation
If traditional pivot-based orientation mechanism is used, then panels can be oriented towards sun, but the system becomes fragile and requires significant maintenance
Solution Approach 1:
The patent replaces traditional pivot-based mechanical orientation with a helicoidal link mechanism that converts rotational motion of the actuator into precise angular adjustment of the panel assembly. This substitution eliminates fragile pivot points and complex bearing assemblies, resulting in a more reliable system with fewer moving parts that require maintenance.
Solution Approach 2:
The helicoidal link mechanism provides inherent mechanical advantage and self-locking properties, where the threaded geometry naturally maintains the panel position without requiring additional locking mechanisms or complex control systems. The system serves itself by using the actuator's rotation to automatically adjust and secure the panel orientation.
3Productivity
If traditional mast structure with high mounting is used, then panels can achieve good sun exposure, but installation becomes difficult and requires strong anchoring
Solution Approach 1:
The patent employs dynamic, adjustable support structures rather than fixed high masts. The elevation-adjustable frame allows the panel assembly to be mounted at various heights and angles, enabling installation on diverse surfaces (ground, roofs, walls) without requiring uniform high anchoring. This dynamic adaptability simplifies installation while maintaining optimal sun exposure through adjustable positioning.

AI summary
A system for generating electrical energy is proposed, comprising a mast intended to be anchored to the ground, at least one solar panel fixed by its edges within a steerable frame to form a flat surface, and a means for orienting said frame to point said panels in a predetermined direction. This orienting means comprises a base that rotates around the vertical mast by means of a first actuator. The frame is pivotally mounted on the rotating base. The frame includes a worm gear driven by a second actuator. The worm gear has a nut secured by a pivot to one end of a connecting rod. The other end of said connecting rod is pivotally mounted on the rotating base. The movement of the nut along the worm gear by the rotation of the second actuator changes the tilt of the frame. In this way, the elements for orienting the solar panels are more compact and offer less wind resistance.
