Adjustable Cleaning Cart Frame for Multi-Space Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning carts are often poorly suited for multiple working environments due to fixed sizes and arrangements, requiring multiple carts for different areas, which is inconvenient and costly to maintain and transport.
Innovation Solution
A cleaning cart with an adjustable frame that allows for varying lengths and heights, along with movable and rotatable receptacles, enabling adaptability to different spaces and applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple conventional cleaning carts of different sizes and arrangements are used for different working environments, then the suitability for specific cleaning applications is improved, but the cost of purchasing, owning, transporting, and storing multiple carts increases
Solution Approach 1:
The cleaning cart employs adjustable components including telescopic bars that can extend and retract to change the cart's length and width, and adjustable uprights that can be repositioned to change height. These dynamic adjustments allow a single cart to adapt to different working environments and cleaning applications, replacing the need for multiple fixed-size carts
Solution Approach 2:
The cleaning cart is designed with universal adaptability through its adjustable frame structure, multiple receptacle configurations, and reconfigurable components. This multi-functionality enables one cart to perform the roles of multiple specialized carts, reducing the total number of carts needed in the fleet
2Device complexity
If a single cleaning cart with fixed dimensions is used, then the simplicity of the cart design is maintained, but the suitability for different working environments and cleaning applications deteriorates
Solution Approach 1:
The cart incorporates dynamic adjustment mechanisms including telescopic bars with locking positions, adjustable uprights with multiple height configurations, and reconfigurable receptacles. These features add functionality while maintaining operational simplicity through intuitive adjustment mechanisms
Solution Approach 2:
The cleaning cart is divided into modular segments including separate bars, uprights, crossbars, and receptacles that can be independently adjusted and reconfigured. This segmentation allows flexible adaptation to different environments while keeping each individual component simple in design
3Adaptability or versatility
If the bar length is made adjustable to change the cart's length and width, then the adaptability to different spaces is improved, but the structural complexity of the frame increases
Solution Approach 1:
The bar structure incorporates telescopic mechanisms that allow length adjustment through extending and retracting segments. The bars can be locked at various positions to define different cart dimensions, providing spatial adaptability while using standardized mechanical components to limit complexity increase
4Adaptability or versatility
If the upright length is made adjustable to change the cart height, then the versatility for different cleaning applications is improved, but the manufacturing complexity increases
Solution Approach 1:
The uprights are designed with adjustable length capabilities through telescopic sections or repositionable segments that can be locked at different heights. This allows the cart height to be customized for different cleaning applications while using modular construction methods to simplify manufacturing processes

AI summary
A cleaning cart supports cleaning supplies and comprises a bar defining a length that is adjustable to change at least one of a length and a width of the cleaning cart, first and second wheels coupled to the bar and separated a distance that is adjustable by varying the length of the bar, an upright coupled to the bar and extending upwardly therefrom, and a receptacle coupled to at least one of the bar and the upright and adapted to hold cleaning supplies therein.
