Solution Overview
Problem
Existing winch designs face difficulties in efficiently reversing the rotating direction to manage counter-rotation when dealing with reverse drag, limiting their applicability and operational efficiency.
Innovation Solution
A brake winch structure with a housing, rotating disk, main shaft, screw adapter, driving screw, and clamping plate, allowing for a temporary release mode that enables contra-rotation by aligning the stud section with the thread groove, enhancing operational efficiency and maintaining safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the trip is arranged to chuck the mechanism of unidirectional ratchet gear wheel for the rotating disk in one direction, then the rotating disk only rotates in one direction and operational safety is improved, but the ability to reverse rotation and meet multiple application requirements deteriorates
Solution Approach 1:
The patent introduces a dynamic switching mechanism between two operational modes: a first mode where the trip chucks the rotating disk for safe unidirectional rotation, and a second mode where the trip releases the rotating disk to enable reverse rotation. This dynamic transition allows the system to adapt between safety priority and versatility priority based on operational needs.
Solution Approach 2:
The patent changes the operational parameter of the trip mechanism from a fixed chucking state to a switchable state between chucking and releasing. By controlling the trip's engagement and disengagement states, the system can transition between restricting rotation direction and allowing reverse rotation, thus resolving the contradiction between safety and versatility.
2Adaptability or versatility
If the trip must be switched to release mode to rotate the rotating disk in opposite direction, then reverse rotation capability is improved, but the operational complexity and difficulty to meet multiple application requirements deteriorates
Solution Approach 1:
The patent merges the trip switching operation with the crank handle operation. The trip switching mechanism is integrated into the crank handle assembly, allowing the user to switch between chucking and releasing modes simply by operating the crank handle in different ways, rather than requiring separate switching operations. This reduces operational complexity while maintaining reverse rotation capability.
3Reliability
If the only way to accelerate contra-rotation is to reverse the crank handle, then safety is maintained, but the working efficiency and productivity deteriorates
Solution Approach 1:
The patent enables preliminary action by allowing the user to pre-position the trip in releasing mode before needing to perform rapid reverse rotation. This preliminary switching to the appropriate operational mode eliminates the need to repeatedly reverse the crank handle during acceleration, thereby improving working efficiency while maintaining safety through controlled trip engagement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient counter-rotation without compromising safety, improving working efficiency and meeting multiple application requirements by allowing rapid release of the rope without reversing the crank handle, thus enhancing the practicality and industrial use of winch products.
Implementation Method 1
The clamping plate is configured with several unidirectional ratchets arranged annularly at intervals. A unidirectional chucking piece is assembled in the auxiliary accommodating space and adjacent to the clamping plate. The unidirectional chucking piece elastically abuts on the corresponding unidirectional ratchet of the clamping plate in normal state, so that the clamping plate only rotates in one direction, its reverse rotation will be chucked.
Implementation Method 2
an elastic underpropping component is assembled between the pressure flange of the driving screw and auxiliary bracket part, the pressure flange is elastically pushed towards the screw adapter in normal state, with the assistance of the elastic underpropping component, the driving screw elastically abuts on the screw adapter in normal state, so that the stud section can be easily screwed in the thread groove
Implementation Method 3
A screw adapter is screwed on the second side wall of the housing. The screw adapter includes an inner connection end and an external end, wherein the inner connection end forms a sleeve joint part which is assembled with the second end of the main shaft to form synchronous rotation. The external end is configured with a thread groove.
Implementation Method 4
A friction driving means is provided, making the pressure flange of the driving screw. The clamping plate and the screw adapter in a tightly synchronized state when the driving screw is displaced towards the screw adapter.

AI summary
Disclosed is a brake winch with reverse release and self-locking functions. The brake winch has a housing with first and second side walls, an accommodating space, and an auxiliary bracket part. A rotating disk is screwed in the accommodating space. A main shaft is screwed on one side of the rotating disk in an interlocking manner. A screw adapter is screwed on the second side wall, and includes an inner connection end that is assembled with the main shaft, and its external end has a threaded groove. The axial displacement of a driving screw, which is screwed on the auxiliary bracket, is matched with the difference of forward and reverse rotation to form a screwing transmission or release mode between the stud section and the thread groove. A friction driving mechanism must prompt the drive screw, the clamping plate and the screw adapter to be in a tightly synchronized state.
