Winch Rewind Adapter for Power Tool Strap Rewinding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rewinding straps on winches is a manual and time-consuming process, especially when multiple winches are used for securing large cargo items, and existing winch bars are not suitable for fast rewind.
Innovation Solution
A high speed winch rewind adapter that allows for actuation using a rotational power tool or socket wrench, featuring a drive connector and extension member to rotate the winch along its axis of rotation, enabling quick strap rewinding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual rewinding is used, then the winch can be operated without additional tools, but the rewinding process becomes time-consuming and labor-intensive
Solution Approach 1:
The adapter serves as an intermediary device that connects power tools or socket wrenches to the winch's annular end, enabling automated or assisted rewinding while maintaining compatibility with existing winch designs. The adapter includes a drive connector that interfaces with the annular end and an external profile that accepts standard power tool attachments.
2Force
If winch bars with long arms are used for tightening, then sufficient torque is achieved, but the device becomes unsuitable for fast rewind operations
Solution Approach 1:
The adapter enables dynamic operation by allowing the winch to be driven at high speeds using power tools or socket wrenches, unlike static winch bars designed only for manual tightening. The adapter's structure accommodates both high-speed rotation for rewinding and maintains torque transmission capability.
3Adaptability or versatility
If multiple winches are used for securing large cargo, then different fixation points are provided, but the total rewinding time increases significantly
Solution Approach 1:
The adapter enables self-service or assisted rewinding by allowing operators to use power tools or socket wrenches to quickly rewind multiple winches simultaneously or in rapid succession, reducing the time penalty associated with using multiple winches for cargo securing.

AI summary
This disclosure describes a high speed winch rewind adapter for quickly rewinding a loading strap. In one implementation, the adapter includes a body having a volume sized to at least partially surround an annular end of the winch. The annular end is coupled with a ratchet mechanism of the winch and having at least one hole for receiving a winch bar. A drive connector is positioned both within the volume of the body and external to the volume of the body, the drive connector external to the volume of the body having an external profile to receive a torque, and the drive connector within the volume of the body insertable into the annular end of the winch for alignment to the axis of rotation. A coupling mechanism synchronizes the drive connector to the annular end such that both the drive connector and the annular end rotate simultaneously.
