Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aircraft landing platforms on boats are unstable due to hull oscillations, making landing maneuvers difficult and dangerous, especially in adverse weather conditions or when exposed to external disturbances.
Innovation Solution
A mechanical self-leveling and active platform with a grid of upper plates controlled by a central management unit, which continuously adapts to external phenomena, maintaining the landing platform in a horizontal position and stabilizing roll, pitch, and heave movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the platform is stably fixed on the boat, then the structural integrity is improved, but the landing maneuver difficulty increases due to hull oscillations
Solution Approach 1:
The platform transitions from a static fixed structure to a dynamic self-leveling system with active stabilization. The platform uses level sensors to detect tilt angles and hydraulic actuators to actively adjust its orientation, maintaining a stable landing surface despite boat hull oscillations. This dynamic adaptation resolves the contradiction by providing both structural integrity through robust mounting and ease of operation through active stabilization.
2Device complexity
If the platform uses classic fixed structure, then the device complexity is reduced, but the stability during oscillation increases
Solution Approach 1:
The platform incorporates self-leveling capabilities through integrated sensors and actuators that automatically detect and correct tilt without external intervention. The system uses level sensors to monitor its orientation and hydraulic actuators to self-correct positioning, providing stable landing conditions while maintaining relatively simple overall structure. This self-service mechanism resolves the contradiction between structural simplicity and oscillation stability.
3Ease of operation
If the platform is designed for short-time stability, then the ease of operation is improved, but the reliability under adverse conditions deteriorates
Solution Approach 1:
The platform implements continuous feedback control through level sensors that monitor tilt angles and provide real-time data to the control system. The hydraulic actuators respond to this feedback by adjusting the platform orientation to maintain horizontality. This closed-loop feedback mechanism ensures both ease of operation through stable landing surfaces and reliability under adverse weather conditions by continuously counteracting oscillations.
4Stability of the object's composition
If the platform uses active stabilization system, then the stability during oscillation is improved, but the device complexity increases
Solution Approach 1:
The platform uses hydraulic actuators to provide active stabilization, leveraging fluid power to counteract oscillation forces. The hydraulic system offers high force output with relatively compact components, achieving stable platform positioning during boat oscillations while keeping the overall system complexity manageable. This hydraulic approach resolves the contradiction by providing effective stabilization without excessive system complexity.
