Payload Stabilization Platform That Avoids Gimbal Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multidimensional gimbal systems are susceptible to gimbal lock, which deteriorates control and reliability, and there is a need for a stabilization platform that can change orientation without disturbing the payload's orientation and achieve compact or spread-out geometry configurations.
Innovation Solution
A stabilizing platform with a frame assembly and handle assembly that allows for switchable orientations, featuring motors that control movement about different axes depending on the handle assembly's orientation, and sensors to detect orientation changes and adjust motor control accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a multidimensional gimbal system is used to stabilize a payload, then the payload can be stabilized in a coordinate system, but the system may encounter gimbal lock which deteriorates control and reliability
Solution Approach 1:
The patent applies dynamics by making the gimbal system configurable between different operational modes (first mode with initial axis orientations, second mode with different axis orientations). This allows the system to dynamically adapt its geometry to avoid gimbal lock conditions while maintaining payload stabilization capability.
Solution Approach 2:
The system changes geometric parameters by switching between different operational modes where the axes have different orientations. This parameter change allows the system to escape from gimbal lock configurations by altering the spatial relationships between rotational axes.
2Adaptability or versatility
If the handle assembly is made switchable between different orientations, then the system can achieve compact or spread-out geometry configurations, but this increases device complexity
Solution Approach 1:
The handle assembly is designed with multi-functionality to serve different purposes: it can be held horizontally for one-handed operation, vertically for two-handed operation, or at intermediate angles. This universal design allows a single component to fulfill multiple operational requirements without requiring separate mechanisms for each configuration.
Solution Approach 2:
The handle assembly is made dynamically reconfigurable rather than fixed, allowing it to switch between different orientations during operation. This dynamic capability enables the system to adapt its geometry for different operational scenarios while using a single mechanical structure.
