Solution Overview

Problem

Existing bottle tank cleaning tools, such as swabs and brushes, face inefficiencies due to their bulky design, limited access through the narrow opening of bottle tanks, and the need for multiple types adapted to different bottle geometries, leading to imperfect cleaning and storage issues.

Innovation Solution

A compact, flat, and flexible swab design with a thin volume of cleaning elements arranged in a U-shaped configuration, allowing for easy insertion and effective residue removal, and a modular structure for easy storage and versatility across various bottle sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional swabs or brushes are used for cleaning bottle tanks, then cleaning action is provided, but the bulky design limits access through narrow openings and creates storage problems

Engineering Contradiction:
Improveaccess through openingVSAvoidswab volume
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The invention transitions from a three-dimensional radial brush structure to a two-dimensional flat cleaning element structure. The cleaning elements are arranged in a substantially planar configuration that can be easily inserted through narrow bottle openings and flattened for compact storage, directly resolving the contradiction between access ease and volume.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The cleaning elements are designed as flexible, thin structures that can bend and conform to the bottle interior surfaces while maintaining a compact form factor. This flexibility allows the flat cleaning element to navigate narrow openings and adapt to curved surfaces without requiring bulky three-dimensional structures.

Inventive Principle:
Principle #30Flexible shells and thin films

2Ease of operation

If the base volume is reduced to pass through bottle necks, then access is improved, but the number of tufts is limited making cleaning inefficient

Engineering Contradiction:
Improvepassage through neckVSAvoidcleaning efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The invention redistributes cleaning elements from a three-dimensional radial arrangement constrained by base volume to a two-dimensional flat arrangement. This dimensional change allows significantly more cleaning elements to be packed into a thin profile that easily passes through bottle necks while maintaining high cleaning efficiency through increased element density in the planar configuration.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If multiple types of brushes are provided for different bottle geometries, then cleaning effectiveness is improved, but device complexity and storage requirements increase

Engineering Contradiction:
Improvecleaning effectivenessVSAvoiduniversal applicability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The flat cleaning element design serves as a universal solution that can effectively clean various bottle geometries and sizes. The two-dimensional configuration and flexibility allow it to adapt to different curvatures and dimensions without requiring multiple specialized brush types, thereby achieving both cleaning effectiveness and universal applicability.

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

Solution Approach 2:

The cleaning elements are designed to be flexible and dynamic, allowing them to adapt their shape and orientation to match different bottle geometries during use. This dynamic adaptability eliminates the need for multiple rigid brush types designed for specific bottle shapes, simplifying the overall system while maintaining cleaning effectiveness across various configurations.

Inventive Principle:
Principle #15Dynamics

4Ease of manufacture

If bristles are repeatedly contacted during transport, then storage is simplified, but the bristles become flattened and lose effectiveness

Engineering Contradiction:
Improvestorage simplicityVSAvoidbristle effectiveness
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The flat cleaning element structure is inherently resistant to permanent deformation from compression during transport. The thin-film design allows it to be flattened for compact storage and then easily rebound to its functional shape upon use, maintaining bristle effectiveness while enabling simple storage in bags with other utensils.

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

The invention relates to a brush (1) including a gripping handle combined with a cleaning head (3), the cleaning head including: a base (5) forming an extension of the handle, including a peripheral wall and an end wall (10), the latter being located opposite the handle; and cleaning elements (7) in the form of hairs attached onto the base. The base is, for example, substantially planar and has a rectangular cross-section, the hairs only being arranged on two opposite sides of the base and at the end thereof, i.e. in the same plane as the base.
