Cleaning Cart Linkage Layout for Compact Stable Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning carts have large dimensions, leading to instability and the risk of utensils protruding over the edge, potentially damaging walls or furniture, and are cumbersome to maneuver in smaller spaces.
Innovation Solution
A cleaning cart design featuring a base plate and working plate connected by non-parallel struts, providing additional space for utensils while maintaining stability and allowing for easy assembly and disassembly, with the struts arranged trapezoidally to enhance stability and create space for utensils on both sides.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If cleaning carts are designed with large dimensions to accommodate all cleaning utensils, then the cleaning cart can hold more utensils, but the cleaning cart becomes unwieldy and may damage walls or furniture
Solution Approach 1:
The patent introduces a vertical dimension by stacking the working plate above the base plate at a vertical distance, connected by linkages. This three-dimensional arrangement allows utensils to be stored in multiple levels (on base plate, between plates, and on working plate) without increasing the horizontal footprint, thus accommodating more utensils while keeping the cart compact and preventing damage to surrounding structures.
2Quantity of substance
If cleaning carts are designed with large dimensions to accommodate all cleaning utensils, then the cleaning cart can hold more utensils, but the cleaning cart becomes cumbersome to maneuver in smaller spaces
Solution Approach 1:
By utilizing vertical space through stacked plates connected by linkages, the design accommodates more utensils without increasing horizontal dimensions. This vertical stacking approach maintains a compact footprint that enhances maneuverability in confined spaces while still providing sufficient storage capacity for all necessary cleaning tools.
3Quantity of substance
If cleaning utensils are fastened to the cleaning cart on the outside, then all utensils can be accommodated, but the cleaning cart becomes even more unwieldy and utensils may protrude over the edge
Solution Approach 1:
The patent employs a nested arrangement where the working plate is positioned within the vertical envelope defined by the base plate and linkages. Utensils are stored in nested configurations between and on the plates, with the linkage structure itself providing support and containment. This nesting approach maximizes storage capacity while keeping the overall external dimensions compact, preventing utensils from protruding beyond the cart's boundary.

AI summary
A cleaning cart has a base plate and a working plate arranged at a vertical distance above the base plate, wherein the base plate and the working plate are connected to each other by a linkage arranged in the vertical distance. The linkage is formed by at least two struts extending non-parallel to each other.
