Solution Overview

Problem

Traditional methods for cleaning bottles, such as using liquid chemicals or physical brushes, struggle to effectively remove solid deposits and debris from the transition area between the sidewall and base of bottles, as existing devices often fail to properly orient their cleaning surfaces against these areas.

Innovation Solution

A brush assembly with a shaft assembly and cleaning assembly, featuring a slot in the second shaft to accommodate a cleaning assembly with bottom and side cleaning members, including retainers and paddles made of fibrous cloth, designed to extend beyond the shaft's diameter for thorough cleaning, anchored by retention pins and heat shrink materials for secure positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional liquid chemicals or steam are used for cleaning bottles, then the cleaning process is simple to operate, but they fail to effectively remove solid deposits and dried fluids from the transition area between sidewall and base

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidoperational simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The cleaning device is segmented into multiple cleaning members with different functions: a bottom cleaning member for the base surface and side cleaning members for the sidewall transition area. This segmentation allows each component to target specific difficult-to-clean areas, improving overall cleaning effectiveness while maintaining ease of operation through automated rotation

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from traditional single-plane cleaning to multi-dimensional cleaning by positioning cleaning members in both horizontal and vertical orientations. The side cleaning members extend radially outward to contact the transition area between sidewall and base, adding a new cleaning dimension that addresses previously inaccessible surfaces

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

2Reliability

If a physical brush is inserted into the container for cleaning, then solid deposits can be removed, but the cleaning surfaces fail to properly orient against the container walls, particularly at the transition area

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidcleaning surface orientation
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

Different parts of the cleaning device have specialized qualities tailored to their specific cleaning tasks. The bottom cleaning member features a flat or slightly curved surface optimized for the base, while side cleaning members have radially oriented surfaces specifically shaped to contact and clean the transition area between sidewall and base, ensuring proper orientation at each location

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The cleaning members are designed with curved surfaces that conform to the cylindrical geometry of the bottle interior. The side cleaning members have radially extending surfaces that match the curvature of the transition area, enabling effective contact and cleaning of the curved surfaces where straight-edged brushes fail

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Area of stationary object

If the cleaning assembly extends beyond the shaft diameter to reach transition areas, then cleaning coverage is improved, but the device complexity increases with multiple components

Engineering Contradiction:
Improvecleaning coverage areaVSAvoidstructural complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

Multiple cleaning functions are merged into a single integrated cleaning assembly that rotates as one unit. The bottom cleaning member and side cleaning members are positioned at different radial distances from the rotation axis but are rigidly connected, allowing simultaneous cleaning of multiple surfaces through a single rotational motion, thereby reducing operational complexity despite increased structural complexity

Inventive Principle:
Principle #5Merging (Combining)
