Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hydraulic cylinders are used to adjust platform position, then the platform can be tilted to compensate for terrain unevenness, but the system becomes complex and prone to stress-induced damage
Solution Approach 1:
The patent replaces the hydraulic cylinder system with an electric motor-driven screw-nut transmission system. This substitution eliminates the complexity of hydraulic components (cylinders, fluid lines, seals) while maintaining the platform position adjustment capability through a more reliable mechanical-electrical system that is less prone to stress-induced damage.
Solution Approach 2:
The patent divides the platform support system into modular components: electric motors, screw-nut transmission units, carriages, and push rods. Each component performs a specific function and can be independently adjusted or replaced, reducing overall system complexity while maintaining adaptability for terrain compensation.
2Manufacturing precision
If rigid connection between screw and vertical guide is used, then precise linear displacement is achieved, but the system becomes vulnerable to stress damage from misalignment
Solution Approach 1:
The patent introduces a carriage as an intermediary component between the screw-nut transmission and the vertical guide. The carriage contains a sliding element that moves along the vertical guide, providing a flexible connection that accommodates minor misalignments while maintaining precise linear displacement. This intermediary protects the screw-nut system from stress damage caused by rigid misalignment constraints.
3Manufacturing precision
If parallelism between screw and vertical guide is strictly maintained, then accurate platform movement is achieved, but manufacturing and assembly difficulty increases
Solution Approach 1:
The carriage acts as a mediator that decouples the strict parallelism requirement from the overall system. The sliding element within the carriage can accommodate minor angular deviations between the screw and vertical guide, allowing assembly with relaxed tolerances while still achieving accurate platform movement through the guided motion of the carriage itself.
4Speed
If quick spatial stabilization is implemented, then platform positioning speed increases, but system complexity and potential failure points increase
Solution Approach 1:
The patent replaces slow-responding hydraulic systems with electric motor-driven mechanisms that can be rapidly controlled and adjusted. Electric motors provide quick response times for platform stabilization while maintaining simpler, more reliable adjustment mechanisms without the complexity of hydraulic control systems, valves, and fluid management.

AI summary
The invention relates to the design of mobile platforms for vehicles used mostly for agricultural purposes. The rotary support includes a platform mounting attachment in the form of a gimbal, whose flanges enable its attachment, respectively, to the vehicle support structure and the lower surface of the platform, and two platform position adjusters located on said support structure. Therein, each platform position adjuster includes an electric drive with a linear displacement unit based on screw-nut transmission and a carriage configured to move along a vertical guide and connected to the linear displacement unit with a pin joint. The support shelf of the carriage bears a push rod made in the form of struts ending with supports and having swivel joints between said supports and struts. Therein, the push rod supports are configured for mounting them on the support shelf of the carriage and on the platform, in this latter case eccentrically to the rotation axes of the gimbal. Thus, the reliability of the structure and the speed of platform stabilization in space are improved.
