Arm-Mounted Aircraft Control Stick With Split Transmitter Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for radio-controlled aircraft are heavy, causing neck and arm fatigue, and do not accurately simulate cockpit controls, limiting operation to large, obstruction-free areas.
Innovation Solution
A control system with a main unit attached to the operator's arm, featuring a control stick with sensors and a separate auxiliary unit containing the transmitter, allowing for comfortable operation and line control in confined spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the battery and transmitter are integrated into the remote control unit, then the control system is compact and easy to manufacture, but the weight increases causing neck and arm fatigue
Solution Approach 1:
The control system is divided into two separate units: a main unit containing the control stick and sensors, and an auxiliary unit containing the battery and transmitter. This segmentation allows the heavy components to be separated from the control interface, reducing the weight burden on the operator's arm while maintaining system functionality through wireless communication.
2Device complexity
If the joysticks are positioned close together, then the control unit is compact, but the operating arrangement becomes unnatural and uncomfortable
Solution Approach 1:
The control interface is segmented into a main unit with the control stick and a separate auxiliary unit. This allows the control stick to be positioned optimally for natural hand operation rather than being constrained by the need to fit multiple components close together, significantly improving ergonomic comfort while maintaining a compact overall system through wireless separation.
3Device complexity
If the control system uses traditional remote control, then it is simple to implement, but it requires large obstruction-free areas for operation
Solution Approach 1:
The traditional mechanical line-control system is replaced with a wireless radio-frequency transmission system. The control stick generates control signals that are transmitted wirelessly to the aircraft, eliminating the need for physical lines and large obstruction-free areas while maintaining simple implementation through standard wireless communication protocols.
4Ease of manufacture
If the control system integrates all components in one unit, then manufacturing is simpler, but arm strain and fatigue increase
Solution Approach 1:
The control system is segmented into a main unit (control stick with sensors) and an auxiliary unit (battery and transmitter). This segmentation reduces the weight that must be supported by the operator's arm, significantly reducing strain and fatigue during operation, while the separate units can be manufactured independently using standard processes and assembled together.

AI summary
A control system for an aircraft includes a main unit and a separate auxiliary unit in communication with the main unit. The main unit includes an arm support allowing attachment to an arm of an operator. The main unit also includes a control stick supported by the structural element and movable in a plurality of directions. The main unit further includes sensors for sensing movement of the control stick. The auxiliary unit includes a transmitter for sending a transmitter signal encoding the movement of the control stick to the aircraft.
