Solution Overview
Problem
Existing mechanical tool trays and creepers lack a reliable, portable, and compact solution for securely holding tools and providing sufficient, stable illumination under vehicles, especially when the vehicle is not fully raised.
Innovation Solution
A mobile tool caddy with inbuilt LED lights, a rechargeable battery, and a magnetic sheet for secure tool holding, designed for easy movement and compact storage, providing instant, stable, and shadowless illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mechanic uses a cordless utility light while working under a vehicle, then the light can be positioned freely, but the light becomes cumbersome to position and the electrical cord trails and gets in the way
Solution Approach 1:
The patent combines the utility light with the creeper assembly by integrating the light housing into the creeper frame structure. The light is powered by a battery mounted on the creeper, eliminating the need for a trailing electrical cord. This merging of the light system with the creeper provides hands-free illumination without cord interference while maintaining positioning flexibility.
2Ease of operation
If tools are placed on a rolling creeper, then mobility is improved, but tools or parts may be displaced from one position to another during rolling
Solution Approach 1:
The patent divides the creeper surface into multiple segmented trays or compartments that are recessed into the creeper frame. Each tray is designed to hold specific tools or parts in designated positions. The segmentation creates physical barriers that prevent tools from sliding or displacing during creeper movement, while the overall assembly maintains full mobility on wheels.
3Illumination intensity
If best garage lighting is used, then illumination is improved, but shadows are thrown under the cars/vehicles
Solution Approach 1:
The patent uses the creeper assembly as an intermediary platform to position the light source directly at the work area under the vehicle. By mounting the light on the creeper frame near the illumination point, the system eliminates shadows that would be cast by overhead lighting. The light follows the mechanic's position, providing consistent shadow-free illumination wherever work is being performed.
4Illumination intensity
If a creeper assembly is extensive to include LED lights, then illumination capability is improved, but the assembly becomes bulky and not portable
Solution Approach 1:
The patent integrates the LED light housing within the existing creeper frame structure, nesting the illumination system inside the hollow spaces of the frame. The battery, light source, and mounting components are arranged to utilize the internal volume of the creeper frame rather than adding external bulk. This nesting approach provides effective illumination while maintaining a compact, portable creeper assembly.
