Winch Engaging Switch Auto-Reset via Planetary Gear Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing winch systems require manual toggling of the engaging-disengaging switch back to an engaged state, which is inconvenient when the user is far away or obstructed, affecting usability and efficiency.
Innovation Solution
An automatic resetting mechanism for a winch engaging-disengaging switch that uses a motor drive assembly to rotate the engaging-disengaging assembly, eliminating the need for manual toggling by automatically inserting the engaging-disengaging shaft into the gear ring locking portion of the planetary gear set.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual rotation resetting method is used, then the engaging-disengaging assembly can be switched between engaged and disengaged states, but the user needs to return to the winch to perform manual rotation resetting which is inconvenient when the user is far away or obstructed
Solution Approach 1:
The system uses the motor drive assembly to automatically reset the engaging-disengaging assembly without requiring user intervention. The motor drive assembly rotates the planetary gear set which through the resetting drive component automatically toggles the engaging-disengaging shaft back to the engaged state, making the system self-serving and eliminating the need for the user to return to the winch for manual resetting.
Solution Approach 2:
The patent replaces the manual mechanical operation with an automated motor-driven system. The motor drive assembly uses electrical motor rotation to drive the planetary gear set, which through mechanical transmission (resetting drive component) automatically performs the engaging-disengaging switching, substituting manual mechanical operation with automated electromechanical system.
2Ease of operation
If automatic resetting mechanism is implemented, then the user does not need to go back to the winch for manual toggling, but the device complexity increases with additional components like motor drive assembly and resetting drive component
Solution Approach 1:
The motor drive assembly serves multiple functions: it drives the planetary gear set for winch operation and simultaneously drives the resetting drive component for automatic engagement resetting. This multi-functionality reduces the need for separate dedicated resetting mechanisms, thereby limiting the increase in device complexity while achieving automatic resetting capability.
Solution Approach 2:
The patent merges the resetting function with the existing motor drive assembly and planetary gear set. The resetting drive component is integrated into the planetary gear set structure, and the motor drive assembly simultaneously performs both winch driving and automatic resetting functions, combining multiple functions into a unified system to minimize additional complexity.

AI summary
An automatic resetting mechanism for a winch engaging-disengaging switch includes a winch bracket, a motor drive assembly, a gear box, a drive shaft, a planetary gear set, and an engaging-disengaging assembly. At least one gear ring locking portion is disposed circumferentially on an outer circumferential wall of a gear ring of the planetary gear set. The engaging-disengaging assembly includes an engaging-disengaging seat, an engaging-disengaging shaft, and an engaging-disengaging toggle sheet. The engaging-disengaging seat is fixed on the gear box. A positioning step is disposed on the engaging-disengaging seat. The engaging-disengaging shaft is penetrated into the engaging-disengaging seat. An engaging-disengaging pin is disposed on a sidewall of the engaging-disengaging shaft. The engaging-disengaging pin is abutted against the positioning step. A resetting drive component in transmission cooperation with the engaging-disengaging toggle sheet is disposed on a planetary gear side plate of the planetary gear set.
