Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motion sensing control methods for movable platforms, such as drones, are inadequate in dangerous flying scenarios, increase user operation burden in normal scenarios, and limit maneuverable range due to insufficient attitude initialization and lack of guidance, leading to suboptimal user experience and safety concerns.
Innovation Solution
A control method and motion sensing remote controller that utilize attitude sensors to generate control commands based on user posture, employing different control strategies in fully locked, semi-locked, and unlocked states to enhance user experience and safety, including specific control logic for various flight scenarios and modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If motion sensing control is used for movable platforms, then user experience is improved through intuitive control, but operational safety deteriorates in dangerous flying scenarios
Solution Approach 1:
The patent implements dynamic control strategies that adapt to different flight scenarios. The system transitions between fully locked state (high safety, low maneuverability), semi-locked state (balanced safety and maneuverability), and unlocked state (high maneuverability, lower safety) based on real-time flight conditions, resolving the contradiction between ease of operation and operational safety
Solution Approach 2:
The system changes control parameters dynamically by adjusting the locking state of the motion sensing remote controller based on flight scenarios and modes. This parameter change allows the system to optimize both user experience and safety by selecting appropriate control sensitivity and responsiveness levels for different operational contexts
2Reliability
If traditional joystick control is used, then operational safety is maintained through direct control, but user experience deteriorates due to inability to directly perceive operation direction
Solution Approach 1:
The patent replaces traditional mechanical joystick control with motion sensing technology that detects user posture and movement. This substitution maintains operational safety through controlled states while dramatically improving user experience by enabling intuitive control where the user's natural movements directly correspond to platform operations
3Device complexity
If motion sensing control with limited attitude initialization is used, then device complexity is reduced, but maneuverable range deteriorates
Solution Approach 1:
The system performs preliminary attitude initialization before flight operations begin. By pre-configuring the control system with proper attitude references and calibration data, the system enables full maneuverable range without increasing operational complexity during flight, as the initialization work is completed beforehand
