Adjustable Auto Parts Cart for Secure Panel Transport and Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing auto parts transport carts are inadequate for securely storing and transporting large panels and various-sized parts, lack adjustability, and occupy excessive space when not in use, limiting efficiency and safety in auto body repair processes.
Innovation Solution
A versatile auto parts cart with independently adjustable legs, cantilevered shelves and baskets, elongate support arms, and cushioned leg extensions that allow for secure storage and transport of large panels, and nesting capabilities to reduce space usage, featuring elastic cords and S-hooks for versatile part suspension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a prior art wheeled cart with fixed shelves is used, then the cart structure is simple, but it cannot accommodate parts of various sizes and lacks adjustability
Solution Approach 1:
The patent implements adjustable shelves that can be repositioned vertically along the cart frame, allowing the storage configuration to dynamically adapt to different part sizes and shapes. This resolves the contradiction by providing versatility without requiring multiple fixed-configuration carts.
Solution Approach 2:
The cart is divided into modular components including adjustable shelves, baskets, and removable panels that can be independently configured. This segmentation allows flexible adaptation to various storage needs while maintaining a relatively simple overall structure.
2Reliability
If large panel parts are transported on a prior art cart, then the cart can carry large items, but the panels swing about the cart during transport causing damage risk
Solution Approach 1:
The patent incorporates panel retainers and securing mechanisms that prevent panels from swinging or shifting before transport issues can occur. This preliminary restraint action eliminates the damage risk associated with unsecured panel transport.
Solution Approach 2:
The cart design includes pre-positioned support structures and adjustable restraints that are ready to secure panels before transport begins. This preliminary preparation ensures panel stability throughout the transport process.
3Area of stationary object
If a prior art cart is used when not in use, then the cart is available for use, but it occupies a large footprint space
Solution Approach 1:
The patent designs the cart with nested components including removable shelves, baskets, and panels that can be stored within the cart frame or nested together when not in use. This nesting capability significantly reduces the footprint occupation while maintaining full functionality when needed.
4Productivity
If multiple trips are made from parts department to work site, then the repair worker can collect necessary parts, but time is lost due to multiple trips
Solution Approach 1:
The patent enables the consolidation of multiple parts collection trips into a single trip by providing a cart with sufficient capacity to carry all necessary parts, tools, and equipment. This merging of multiple trips into one significantly improves repair efficiency and reduces time loss.

AI summary
An improved utility cart for use in auto body repair facilities. The cart includes an upright frame from which one or more shelf or basket members extend generally horizontally. Extensions on the spaced apart legs of the cart include at least two elongate upright posts which are spaced apart sufficiently to receive a thin auto body part such as a hood panel or windshield. Elongate support arms may be attached to the upright members of the frame by inserting tabs of the arms into slots in the upright members. The shelf and basket members are supported on a pair of side brackets which have tabs which are received in slots in the upright members. The legs may be adjusted from a parallel position to one which has the legs diverging. The legs are supported by casters mounted at the ends of the legs and at the ends of the leg extensions. A small parts drawer may be carried in a drawer support which can be suspended from either a shelf or a basket member. S-hooks and elastic cords may be attached to cross bars separating the upright members, or from the elongate support arms or the side brackets of the shelf or basket members.
