Modular Baker's Dolly with Coupled Rolling Racks

Solution Overview

Problem

Current baker's dollies are limited in transporting larger loads and lack mechanisms to easily roll single or stacked racks, restricting the versatility and efficiency of load transportation.

Innovation Solution

The design incorporates universal mounts for casters and coupling members that allow racks to be coupled and rolled in a common horizontal plane, enabling modular configuration and easy movement with a handle, enhancing the ability to transport multiple loads without the need for direct pushing or pulling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If baker's dollies are configured to transport loads stacked on top of one another, then multiple loads can be transported, but the ability to transport bigger loads is limited

Engineering Contradiction:

Improvenumber of loads transportedVSAvoidability to transport bigger loads

Core Design Contradiction:

Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The dolly system is divided into multiple independent racks that can be used separately or combined. Each rack can transport loads individually, or multiple racks can be coupled together to transport larger or heavier loads, providing both quantity capacity and adaptability for different load sizes

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Racks are designed to nest within one another when not in use, allowing compact storage. When needed, racks can be coupled together in various configurations (side-by-side, stacked, or combined) to create larger transport capacity for bigger loads

Inventive Principle:

Principle #7Nested doll (Nesting)

2Quantity of substance

If baker's dollies are provided with multiple levels of racks, then many loads can be transported with one dolly, but mechanisms to easily roll single racks or stacks of racks are lacking

Engineering Contradiction:

Improvenumber of loads transportedVSAvoidease of rolling racks

Core Design Contradiction:

Quantity of substanceVSEase of operation

AI summary

A baker's dolly includes a plurality of racks and at least one coupling member. The racks each include a shelf portion and a plurality of casters coupled to the shelf portion. The racks include a first rack and a second rack. The coupling member couples the first rack to the second rack in order to allow each of the first and second racks to each be rolled in a common horizontal plane.
