Flight Kinesthesia Simulator with Dual-Axis Swing and Flip Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current kinesthetic devices simulating flight require multiple actuators, leading to increased complexity, cost, and difficulty in control, while failing to accurately replicate the kinesthesia of ascending and descending motions.
Innovation Solution
A kinesthetic device with a reduced set-up space and simplified control system, utilizing two swing support structures and a flip unit with motors and push-and-pull rods to simulate flight kinesthesia, where the swing and flip units operate independently to mimic ascension, descending, forward falling, and backward lifting motions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If six sets of actuators are used to simulate flight kinesthesia, then the simulation accuracy is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts and eliminates redundant actuators from the traditional six-degree-of-freedom system. By analyzing the specific flight kinesthesia requirements (ascending, descending, forward falling, backward lifting), the invention identifies that only two actuators are needed: one for swing motion (ascending/descending) and one for flip motion (forward falling/backward lifting), thereby reducing complexity while maintaining simulation accuracy
Solution Approach 2:
The swing actuator performs multiple functions: it controls both the swing support structure's angular position and indirectly influences the riding seat's orientation. The flip actuator similarly controls the riding seat's flipping angle. This multi-functionality reduces the need for separate actuators for each degree of freedom, achieving flight kinesthesia simulation with fewer components
2Measurement precision
If multiple extendable rods are disposed alternately between platforms, then the flight simulation is improved, but the action of one rod affects other rods, increasing control difficulty
Solution Approach 1:
The patent segments the flight simulation into two independent motion components: swing motion (ascending/descending) and flip motion (forward falling/backward lifting). Each component is controlled by a separate actuator system, eliminating the coupled interference present in traditional six-degree-of-freedom systems where extendable rods affect each other. This segmentation simplifies control while maintaining simulation accuracy
Solution Approach 2:
The patent introduces intermediate pivot points and support structures (swing support structure pivoted at the base seat, riding seat pivoted at the swing support structure) that mediate between the actuators and the riding seat. These intermediaries isolate the control actions, allowing the swing actuator to control swing motion independently from the flip actuator's control of flip motion, thereby reducing control difficulty
3Measurement precision
If extendable rods are extended or compressed significantly to simulate plane kinesthesia, then the simulation accuracy is improved, but the setup size and part dimensions increase
Solution Approach 1:
The patent employs dynamic pivot points and rotational joints that allow compact motion simulation through angular displacement rather than large linear extensions. The swing support structure pivoted at the base seat and the riding seat pivoted at the swing support structure enable flight kinesthesia simulation through rotational movement, eliminating the need for significantly extended or compressed rods and reducing overall setup size
