Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld controllers for remotely controlling mechanisms like unmanned vehicles are inflexible, bulky, unintuitive, difficult to upgrade, and consume significant power, lacking the high-level functionality of larger non-handheld controllers.
Innovation Solution
A handheld device with sensors, processing capabilities, and wireless communication that translates user maneuvers into vector commands to control mechanisms, allowing intuitive operation without the need for extensive finger movement or network connectivity, and enabling gesture and speech recognition for control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional non-handheld OCUs are used for controlling mechanisms, then high-level functionality and control capability are improved, but device weight, bulk, and power consumption increase significantly
Solution Approach 1:
The patent replaces traditional mechanical control interfaces (buttons, switches, physical controls) with gesture-based control and speech recognition. The handheld device uses sensors to detect hand gestures and voice commands, translating them into control signals for the mechanism, thereby eliminating the need for bulky mechanical control components while maintaining high-level functionality.
Solution Approach 2:
The patent introduces a wireless communication intermediary between the handheld device and the mechanism. The controller transmits control commands wirelessly (via Bluetooth, Wi-Fi, or other wireless protocols), eliminating the need for heavy wired connections and physical control linkages, thus reducing device weight and bulk while preserving control capability.
2Weight of moving object
If traditional handheld controllers are designed for better form factors, then portability and ease of carrying are improved, but functionality is reduced to mere repackaging of traditional interfaces
Solution Approach 1:
The patent implements a universal control system that can operate multiple types of mechanisms (drones, robots, vehicles, etc.) through a single handheld device. The device supports multiple control modes including gesture recognition, speech recognition, and traditional button controls, making it adaptable to various applications while maintaining a compact form factor.
Solution Approach 2:
The patent employs dynamic control interfaces that adapt to different operating conditions and user preferences. The system can switch between gesture-based control, voice commands, and traditional button interfaces depending on the situation, providing high-level functionality in a compact device without being limited to a single control mode.
3Measurement precision
If traditional controllers are designed with extensive physical interfaces, then control precision is improved, but intuitiveness and ease of use deteriorate
Solution Approach 1:
The patent replaces complex mechanical control interfaces with intuitive gesture-based and voice-based controls. Hand gestures naturally map to desired mechanism movements (e.g., pointing direction corresponds to movement direction), and voice commands provide direct verbal control, both maintaining precision while dramatically improving intuitiveness compared to traditional button and switch interfaces.
