Nesting Utility Cart Wheel Recess Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rolling carts lack compact stackability, stability, and transport stability, leading to inefficiencies in loading and unloading products from trailers, which results in increased labor and time in distribution centers and retail stores.
Innovation Solution
The Nesting Utility Cart (NUC) design features a cart deck with specific wheel and orifice configurations that allow for secure and compact stacking, enabling efficient nesting and disassembly, facilitating high-density storage and easy transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional rolling carts are used for product transport, then labor productivity is improved through easy on/off-loading, but stackability and transport stability deteriorate
Solution Approach 1:
The cart deck is designed with recesses that receive wheels from overlaying cart decks, creating a nested configuration where multiple cart decks stack vertically with wheels protruding below the bottom surface. This nesting arrangement enables compact storage while maintaining structural stability through interlocking wheel-recess connections between stacked carts.
2Ease of operation
If conventional rolling carts are used for product transport, then ease of operation is improved through maneuverability, but storage volume efficiency deteriorates
Solution Approach 1:
The cart deck incorporates recesses positioned to receive wheels from overlaying decks, allowing cart decks to nest vertically in a stacked configuration. This nesting reduces the overall storage volume required by enabling compact vertical stacking, while the wheels that protrude below the bottom surface maintain the cart's maneuverability when deployed.
3Ease of operation
If conventional rolling carts are used for product transport, then ease of operation is improved through on/off-loading capability, but transport stability deteriorates
Solution Approach 1:
The cart deck is designed with recesses that interlock with wheels from overlaying cart decks in a nested stacking arrangement. This interlocking wheel-recess connection provides transport stability by mechanically securing stacked carts together, preventing shifting during transit while preserving the ease of on/off-loading capability when carts are deployed individually.

AI summary
A nesting utility cart is disclosed comprising wheels fixed to a cart deck. The cart decks may stack on top of each other such that at least a portion of the wheels of an overlaying similar cart deck may protrude below the bottom surface of the cart deck that it overlays. The protrusion of wheels through the cart deck may lock all of the stacked cart decks together. Tubing and netting may be fixed to the cart decks to form side walls securing cargo on the nesting utility cart.
