Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote control systems require two hands or additional switches to achieve 3-D control, making it difficult to control remote-controlled devices like model airplanes or helicopters, and rely on visual feedback to adjust angles, increasing the risk of losing control.
Innovation Solution
Incorporating an acceleration sensing module in both the remote controller and the remote-controlled device, allowing the device to detect its own acceleration and synchronize its motion with a target motion signal from the controller, enabling one-handed 3-D control and reducing the need for visual feedback through a closed-loop real-time feedback system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a stick and variable resistor are used to generate control signals, then the control system can be simple in structure, but it requires two hands or additional switches to achieve 3-D control
Solution Approach 1:
The patent replaces the mechanical stick and variable resistor system with an acceleration sensing module that uses sensors (such as accelerometers) to detect motion in three-dimensional space. This substitution eliminates the need for manual manipulation of multiple controls while maintaining simple overall system structure, allowing one-handed 3-D control through natural hand movements.
Solution Approach 2:
The acceleration sensing module serves multiple functions: it detects acceleration in three dimensions, determines orientation, and provides control signals for all three axes of motion. This multi-functional component replaces what would traditionally require separate mechanical controls for each axis, simplifying the operation to a single handheld device.
2Device complexity
If the stick controls the rear fin angle directly, then the control signal generation is simple, but the user must use visual feedback to adjust angles which increases the risk of losing control
Solution Approach 1:
The patent implements a feedback mechanism where the acceleration sensing module continuously monitors the remote-controlled device's motion and orientation. The detected acceleration data is processed to determine the device's attitude, and this information is used to automatically adjust control signals. This closed-loop feedback system eliminates the need for visual feedback by the operator, as the system self-corrects based on sensor data, significantly improving control stability and reducing the risk of losing control.
