Cordless Drill Adapter for Cargo Winch Collar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rewinding cargo winch straps by hand is a tedious and labor-intensive task that can cause muscle strain and cramping, especially when dealing with multiple straps.
Innovation Solution
A cordless drill with an adapter that automatically grips and releases the cargo winch collar when reversing and forwarding, utilizing pivoting jaws to securely engage and disengage the collar without manual alignment, facilitating efficient strap rewinding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a cordless drill with an adapter is used to rewind cargo winch straps, then productivity is improved, but device complexity increases
Solution Approach 1:
The adapter is designed to automatically grip and release the collar through pivoting jaws that self-engage when the drill rotates in reverse, and self-release when rotated forward, eliminating the need for manual alignment or operation of the gripping mechanism
Solution Approach 2:
The jaws are designed to pivot between open and closed positions dynamically based on the direction of drill rotation, allowing automatic engagement and disengagement of the collar without manual intervention
2Ease of operation
If manual alignment of adapter teeth with collar holes is required, then ease of operation deteriorates, but manufacturing precision can be reduced
Solution Approach 1:
The adapter automatically aligns its teeth with the collar holes through the pivoting jaw mechanism that self-engages when the drill rotates in reverse, eliminating the need for manual alignment by the operator
Solution Approach 2:
The pivoting jaws are positioned and oriented in advance to automatically find and engage with the collar holes when the drill is activated in reverse, preparing the alignment action before the actual gripping occurs

AI summary
A driver for rewinding a cargo winch strap includes a cordless drill and an adapter. The adapter fits into the chuck of the drill and has two movable jaws. The jaws close onto and grip the collar of the cargo winch as soon as the drill is placed into reverse and open to release the collar as soon as the direction of the drill is changed from reverse to forward.
