Aircraft Control Stick Base Alignment for Ergonomic Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aircraft control devices face limitations in ergonomics and compatibility between control sticks and bases, affecting the usability and adaptability of joystick systems.
Innovation Solution
A base system for aircraft joysticks featuring a pipe-shaped absorption and a socket nut with a radial outer thread, along with safety segments and a grip adapter plate, enhances ergonomics and compatibility by providing adjustable alignment and secure attachment options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a control stick is mounted on a base with fixed geometry, then the structural simplicity is maintained, but the ergonomics and compatibility with different aircraft cockpits are limited
Solution Approach 1:
The base system incorporates adjustable alignment mechanisms that allow the control stick to be positioned at different angles and orientations. The base flange can be rotated and adjusted to achieve optimal ergonomic alignment with the pilot's seating position, transforming a static structure into a dynamically adjustable one.
Solution Approach 2:
The base is divided into separate functional components including a base flange, alignment elements, and mounting structures. This segmentation allows each component to be independently adjusted and configured, enabling compatibility with different control stick types and cockpit configurations without redesigning the entire base structure.
2Ease of operation
If control sticks with different orientations are used, then the ergonomics are improved, but the alignment precision and secure attachment become more difficult to achieve
Solution Approach 1:
The base flange is pre-configured with multiple alignment elements and reference features that guide the positioning of the control stick. These pre-built alignment mechanisms ensure that even when adjusting to different orientations, the control stick maintains precise alignment with the aircraft's control axes, eliminating the need for complex post-installation adjustments.
