Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gimbal motors are limited in rotation angle and application scenarios due to mechanical limits imposed to prevent wire twisting or short circuits, which restrict the rotation of the gimbal.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical limits are added to prevent wire twisting or short circuits, then wire safety is improved, but motor rotation angle is limited
Solution Approach 1:
The patent extracts the wire connection from the rotation system by using a conductive post that rotates with the motor shaft, separating the electrical connection function from the mechanical rotation constraint. This allows the motor to rotate freely without wire twisting while maintaining electrical connectivity through the rotating conductive post structure.
Solution Approach 2:
The conductive post is nested within the motor shaft hollow structure, with the conductive post rotating together with the motor shaft. The insulating layer is nested between conductive parts on the conductive post. This nested arrangement allows multiple functional elements to coexist in a compact space while enabling unrestricted rotation.
2Device complexity
If traditional wire connections are used, then electrical connection is simple, but motor rotation is restricted
Solution Approach 1:
The patent transforms the static wire connection into a dynamic structure where the conductive post rotates together with the motor shaft. The conductive post includes insulating layers and conductive parts that maintain electrical connection during rotation, enabling the motor to achieve unlimited rotation angles while maintaining reliable electrical connectivity.
3Length of moving object
If conductive post with insulating layers is used, then unrestricted rotation is achieved, but device complexity increases
Solution Approach 1:
The patent merges the electrical connection function with the mechanical rotation function by integrating the conductive post (with insulating layers) directly onto the motor shaft. This combined structure eliminates the need for separate wire connections and rotation mechanisms, achieving unrestricted rotation while maintaining relatively simple overall device structure.
