Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flight simulation control systems lack an efficient mechanism to generate realistic operating reaction forces, leading to reduced realism and stability in aircraft simulation training, particularly in VR environments.
Innovation Solution
The flight simulation control apparatus incorporates a reaction force generator with a tension spring and a dual-arm mechanism that deforms when rotated, providing a more realistic operating reaction force and allowing for reduced size and complexity, while also enabling precise neutral position detection and trim adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional single-axis spring mechanism is used to generate operating reaction force, then the structure is simple, but the realism and stability of the simulation are insufficient
Solution Approach 1:
The control mechanism is segmented into two independent arms (first arm and second arm) that can rotate about different axes (second axis and third axis). Each arm independently deforms the elastic structure when rotated, allowing bidirectional rotation of the operator about the first axis while maintaining simulation stability through distributed elastic force generation.
Solution Approach 2:
The elastic structure serves multiple functions: it generates operating reaction forces during rotation, provides neutral position detection capability, and enables trim adjustments. The transferer mechanism also serves dual purposes by transferring rotation to either the first arm or second arm depending on the rotation direction, consolidating multiple functions into a unified system.
2Reliability
If a dual-arm mechanism with transferer is implemented for realistic reaction force generation, then the realism and stability improve, but the device size and complexity increase
Solution Approach 1:
The transferer merges the functionality of two separate rotation transfer mechanisms into a single component. When the operator rotates in one direction, the transferer directs the motion to the first arm; when rotating in the opposite direction, it directs to the second arm. This merging approach generates realistic bidirectional reaction forces while minimizing the overall volume by sharing common components.
3Ease of operation
If the elastic structure is deformed through arm rotation to generate reaction force, then the operating experience realism improves, but the mechanism requires precise neutral position detection
Solution Approach 1:
The system incorporates neutral position detection that provides feedback to the trim adjustment mechanism. When the operator releases the control stick, the detection mechanism identifies the neutral position where the first arm and second arm return to their initial positions. This feedback enables automatic trim adjustments to maintain accurate neutral positioning, enhancing operating realism while ensuring measurement precision through continuous monitoring and adjustment.

AI summary
A simulation control apparatus includes a control stick that rotates about an axis X1 in both directions, and a reaction force generator including a tension spring that is deformed by rotation of the control stick and generates an operating reaction force of the control stick. The reaction force generator includes a transferer that is connected to the control stick and rotates together with the control stick, a first arm that rotates about an axis X2 and deforms the tension spring when rotation of the control stick in one direction is transferred to the first arm through the transferer, and a second arm that rotates about an axis X2 and deforms the tension spring when rotation of the control stick in another direction is transferred to the second arm through the transferer.
