Gimbal Rocker Control for Precise One-Hand Optical Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gimbals used in video shooting, photo taking, and surveillance often have poor hand feel and are inconvenient to operate due to the use of multiple keypads or remote controllers for controlling optical devices, leading to low accuracy and requiring multiple persons for handheld operation.
Innovation Solution
A gimbal system featuring a rocker with a potentiometer assembly and keypad for easy operation, allowing single-person control with improved hand feel, utilizing a controlling device that sends control instructions to a performing assembly to manage pitch and rotation actions of optical devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple keypads or remote controller are used to control the optical device, then the control coverage is improved, but the operation convenience deteriorates
Solution Approach 1:
The patent combines multiple control functions into a single integrated controlling device with a unified operation interface. Instead of using separate keypads or remote controllers, the invention integrates pitch control, rotation control, and mode switching into one device that the operator can handle with one hand, thereby maintaining full control coverage while significantly improving operation convenience.
2Measurement precision
If multiple keypads are used to control pitch and rotation, then the control precision may be improved, but the hand feeling deteriorates
Solution Approach 1:
The patent merges pitch control and rotation control into a single integrated controlling device. The operator holds one device with both controls, maintaining precise control over pitch and rotation angles through well-positioned control elements, while achieving excellent hand feeling and operational comfort that multiple separate keypads cannot provide.
3Adaptability or versatility
If remote controller is used for wireless control, then the operation flexibility is improved, but the system complexity deteriorates
Solution Approach 1:
The patent extracts the wireless communication functionality from the controlling device, incorporating a transmitter that can operate independently without requiring a separate receiver unit. This extraction eliminates the need for paired receiver-transmitter systems, reducing overall system complexity while maintaining wireless operation flexibility.
4Reliability
If multiple persons are required to operate the gimbal, then the operational reliability may be improved, but the ease of operation deteriorates
Solution Approach 1:
The patent combines all necessary control functions for pitch, rotation, and mode switching into a single handheld controlling device that can be operated by one person. The integrated design ensures that all control elements are within easy reach and can be operated simultaneously or sequentially by a single operator, maintaining full operational reliability while enabling single-person operation.
