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

VSEngineering 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

Engineering Contradiction:
Improvesuitability for specific cleaning applicationsVSAvoidnumber of carts required
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

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

Inventive Principle:
Principle #15Dynamics

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improvesimplicity of cart designVSAvoidsuitability for different working environments
Core Design Contradiction:
Device complexityVSAdaptability or versatility

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

Inventive Principle:
Principle #15Dynamics

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

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improveadaptability to different spacesVSAvoidstructural complexity of the frame
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
Improveversatility for different cleaning applicationsVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

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

Inventive Principle:
Principle #15Dynamics
