Lug Nut Loosening Assembly Using Vehicle Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lug nut devices do not harness vehicle motion to facilitate loosening or tightening of lug nuts, requiring manual effort or power tools.
Innovation Solution
A coupler with an axle aperture and pair of wheels that transfers rearward vehicle motion into counter-clockwise rotation of a lug wrench to loosen lug nuts, and forward motion for tightening, eliminating the need for manual manipulation or power tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual effort or power tools are used to loosen lug nuts, then the lug nuts can be loosened, but user effort is high and power tools are required
Solution Approach 1:
The device allows the vehicle's own motion to perform the work of loosening the lug nuts. The vehicle moves itself through the mechanism, with the wheels and axle converting vehicle motion into rotational force on the lug wrench, eliminating the need for external power tools or manual effort
Solution Approach 2:
The device transforms the static application of force into a dynamic system that utilizes the vehicle's motion. The movable wheels and axle create a dynamic mechanism that converts linear vehicle movement into rotational motion of the lug wrench, making the loosening process more efficient
2Force
If a lever is used for loosening lug nuts, then mechanical advantage is gained, but the device cannot harness vehicle motion
Solution Approach 1:
The device serves multiple functions: it provides mechanical advantage like a traditional lever, harnesses vehicle motion, and can work with any vehicle that can roll forward. The universal design allows the same mechanism to convert vehicle motion into useful rotational force for loosening lug nuts on different vehicles
Solution Approach 2:
The axle and wheels act as intermediaries that transfer and transform the vehicle's linear motion into rotational motion of the lug wrench. This intermediary mechanism bridges the gap between the vehicle's forward movement and the rotational force needed to loosen the lug nuts
