Cordless Drill Spare Tire Tool for Strain-Free Winch Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spare tire handling systems require significant manual effort and strain, especially for users of all ages, to lower and raise spare tires stored under vehicles, as they often necessitate the use of bulky and cumbersome crank handles.
Innovation Solution
A tool kit comprising a tubular rod with a male connector for a cordless drill and a tip connector that inserts into a vehicle's winch tube, allowing the cordless drill to rotate the rod and lower the spare tire without manual cranking, providing a portable, sturdy, and customizable solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a winch-type mechanism with manual crank is used to lower spare tire, then the spare tire can be lowered from under vehicle, but significant manual effort and strain is required especially for users of all ages
Solution Approach 1:
The patent replaces the manual mechanical crank system with an electric motor-driven system. The motor automatically rotates the winch drum to lower and raise the spare tire, eliminating the need for users to manually rotate a bulky crank handle, thereby significantly reducing manual effort and strain.
Solution Approach 2:
The winch mechanism is designed to operate automatically through electric motor activation. The system serves itself by using the motor to perform the work of rotating the drum, rather than requiring external manual intervention from the user to crank the mechanism.
2Ease of operation
If a bulky and long detachable hand crank is used to rotate the winch, then the spare tire can be lowered, but the device becomes difficult for women and elderly people to operate
Solution Approach 1:
The patent substitutes the bulky mechanical hand crank with a compact electric motor assembly. The motor integrates the driving function into a smaller, more manageable unit that can be easily attached to and removed from the winch drum, reducing device complexity and improving ease of operation for all users.
Solution Approach 2:
The system is divided into separable components: the winch drum, the electric motor, and the connecting mechanism. This segmentation allows the motor to be detached and stored when not in use, reducing the perceived bulkiness and complexity during operation while maintaining full functionality.
3Productivity
If manual labor is required to rotate the crank handle, then the winch can be operated, but overexertion and strain are placed on the user
Solution Approach 1:
The patent replaces the manual labor-intensive mechanical cranking system with an electric motor that automatically performs the rotation. This substitution eliminates overexertion and strain on the user while maintaining or improving the speed of spare tire lowering, as the motor can rotate the drum more quickly and consistently than manual cranking.
Solution Approach 2:
The electric motor acts as an intermediary between the user's activation input and the mechanical winch operation. Instead of the user directly applying force to rotate the crank, the user simply activates the motor, which then mediates the conversion of electrical energy to mechanical rotation, eliminating direct physical strain on the user.

AI summary
The present invention relates to a vehicle's spare tire tool used for lowering down a spare tire stowed underneath of a vehicle, such as pick-up truck, SUV or any other off-road vehicle. The tool can also be used for stowing the tire back to the bottom of the vehicle. The tool kit features a 13″ tubular rod, that is designed to fit into a cordless drill, using an integrated male connector for rotating the rod. The rod also accommodates a connecting tip for hooking into a winch system of the vehicle. The rod with the attached connecting tip is inserted into an access hole at the rear of the vehicle and is rotated by the cordless drill. The tool kit enables users of all ages to easily dismount spares without overexertion or strain.
