Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gimbal devices are limited to two-axis motion, which is insufficient for multi-angle and multi-direction adjustments, and requires users to manually adjust the target device, making them inconvenient to use.
Innovation Solution
The gimbal device incorporates a lifting module, a horizontal rotating module, a pitch module, and a swing module, enabling four-axis motion through interconnected gear racks and synchronous pulleys, allowing for vertical movement, horizontal rotation, front-rear pitching, and left-right swinging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional gimbal devices are designed with only two-axis motion (horizontal rotation and pitch rotation), then the device structure remains simple, but the motion forms are limited and cannot meet multi-angle and multi-direction adjustment requirements
Solution Approach 1:
The gimbal device is divided into four independent modules: lifting module (vertical movement), horizontal rotating module (horizontal rotation), pitch module (front-rear pitching), and swing module (left-right swinging). Each module can be adjusted independently, enabling multi-angle and multi-direction motion while maintaining modular structure that simplifies the overall design complexity
Solution Approach 2:
The patent transitions from conventional two-axis motion to four-axis motion by adding vertical movement (lifting module) and left-right swinging (swing module) dimensions. This dimensional expansion allows the gimbal to achieve multi-angle and multi-direction adjustment capabilities, transforming the motion space from 2D to 4D
2Ease of operation
If conventional gimbal devices are designed with limited operation angle, then the device structure remains compact, but users need to adjust the target device relying on their own motion, making the device inconvenient to use
Solution Approach 1:
By segmenting the adjustment functions into four separate modules, each module can operate within its own optimized range while contributing to the overall large adjustment capability. This segmentation allows the device to achieve large effective operation angles without requiring a single oversized component
Solution Approach 2:
The four modules are nested or interconnected in a compact arrangement where the lifting module, horizontal rotating module, pitch module, and swing module are integrated in sequence. This nesting allows the multi-axis adjustment mechanism to achieve large operation angles while maintaining a compact overall device volume
