Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current kinesthetic devices simulating flight in six degrees of freedom are not realistic enough, require complex control systems, and are costly due to the need for multiple actuators, which increases setup size and difficulty.
Innovation Solution
A kinesthetic device comprising a base unit, a swing unit with two equal and parallel swing support structures, and a flip unit, controlled by a kinesthetic controller to simulate the kinesthesia of flight using a swing actuator and flip actuator, reducing the number of actuating parts and simplifying control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If six sets of actuators are used to simulate flight in six degrees of freedom, then the kinesthesia simulation capability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent divides the flight simulation into two separate functional units: a swing unit that handles ascension and descending motions, and a flip unit that handles pitching motions. This segmentation allows each unit to use fewer actuators (two swing actuators and two flip actuators) while collectively achieving the desired flight simulation effect, thereby reducing the total number of actuators from six to four.
Solution Approach 2:
The swing support structures serve multiple functions: they provide structural support for the riding seat, enable swing motions for ascension/descending simulation, and work in conjunction with the flip support structures to achieve comprehensive flight simulation. This multi-functionality reduces the need for separate actuators for each degree of freedom.
2Manufacturing precision
If six sets of actuators are used to simulate flight, then the motion simulation accuracy is improved, but the setup size and difficulty increase
Solution Approach 1:
By separating the simulation functions into swing and flip units with dedicated support structures, the patent simplifies the control system and reduces setup complexity. Each unit can be calibrated and adjusted independently, making the overall system easier to manufacture and set up compared to a fully integrated six-actuator system.
3Reliability
If extendable rods are disposed alternately between platforms to simulate flight, then the basic motion simulation is achieved, but the use size and setup size increase
Solution Approach 1:
The flip support structures are nested within or integrated with the swing support structures. The flip actuators are positioned within the swing unit structure, allowing the flip function to be embedded within the swing framework. This nesting reduces the overall footprint and setup size while maintaining both swing and flip simulation capabilities.

AI summary
A kinesthetic device that simulates flight includes a base unit and a swing unit. The base unit includes a base seat; whereas, the swing unit includes a swing seat, two swing support structures pivoted between the base seat and the swing seat, and a swing actuator used to control the swing positions of the two swing support structures. The two swing support structures are equal in length and parallel to each other. A fixed baseline is formed between two junction points between the two swing support structures and the base seat, a swing baseline is formed between two junction points between the two swing support structures and the swing seat, and the fixed baseline and the swing baseline are equal in length. The two swing support structures, the fixed baseline and the swing baseline form a parallelogram, allowing the swing support structures to swing stably the base seat.
