Solution Overview

Problem

Conventional cleaning sponge roller cores experience nonuniform fluid distribution and slow fluid replacement due to small hole openings, leading to uneven cleaning fluid supply and prolonged fluid changeover times.

Innovation Solution

A cylindrical core with a bore diameter of 10 mm or more and small holes with diameters of 2.5 mm or more, where the total cross-sectional area of the holes is larger than the bore area, allowing for even fluid distribution and quick replacement, with holes distributed in both axial and circumferential directions and grooves to manage fluid flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If small holes with small opening areas are used in the core, then the structural integrity and support are improved, but the fluid distribution becomes nonuniform and fluid replacement becomes slow

Engineering Contradiction:

Improvestructural integrityVSAvoidfluid replacement speed

Core Design Contradiction:

StrengthVSProductivity

Solution Approach 1:

The patent changes the critical parameter of hole opening area from small to large (2.5mm or more diameter). This parameter change resolves the contradiction by enabling both adequate structural support and rapid fluid replacement, as the larger openings allow cleaning fluid to quickly enter and replace fluid in the sponge roller while maintaining sufficient wall thickness for strength.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent segments the fluid distribution system into multiple large holes distributed across the core surface. This segmentation approach allows fluid to be supplied uniformly across multiple locations simultaneously, improving both fluid distribution uniformity and replacement speed while maintaining structural integrity through distributed load bearing.

Inventive Principle:

Principle #1Segmentation

2Strength

If small holes with small opening areas are used in the core, then the structural integrity is improved, but the cleaning fluid supply becomes nonuniform

Engineering Contradiction:

Improvestructural integrityVSAvoidfluid distribution uniformity

Core Design Contradiction:

StrengthVSManufacturing precision

Solution Approach 1:

The patent changes the hole opening area parameter to be large (2.5mm diameter or more), which fundamentally alters the fluid flow characteristics. This enables uniform fluid distribution across the sponge roller surface while maintaining structural integrity, resolving the contradiction between strength and manufacturing precision.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent applies local quality by distributing multiple large holes across different locations on the core surface. Each local region receives fluid through its own large opening, ensuring uniform overall distribution while each location maintains adequate structural support.

Inventive Principle:

Principle #3Local quality

3Device complexity

If small holes are used for fluid supply, then the core structure is simplified, but the fluid changeover time is prolonged

Engineering Contradiction:

Improvecore structure simplicityVSAvoidfluid changeover time

Core Design Contradiction:

Device complexityVSLoss of time

Solution Approach 1:

The patent changes the hole size parameter to large dimensions (2.5mm or more diameter) while maintaining the simple core structure. This parameter change enables rapid fluid changeover through the simplified structure, resolving the contradiction between device complexity and time loss.

Inventive Principle:

Principle #35Parameter changes

4Loss of energy

If cleaning fluid is supplied through small holes, then the pressure loss is reduced, but the localized fluid flow is prevented

Engineering Contradiction:

Improvepressure lossVSAvoidfluid flow distribution

Core Design Contradiction:

Loss of energyVSManufacturing precision

Solution Approach 1:

The patent changes the hole opening area parameter to large dimensions, which simultaneously reduces pressure loss and prevents localized fluid flow. The large openings allow fluid to distribute evenly across the sponge roller surface rather than concentrating in localized areas, resolving both issues at once.

Inventive Principle:

Principle #35Parameter changes

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Ensures uniform fluid supply over the sponge roller surface and rapid fluid changeover, reducing pressure loss and preventing localized fluid flow, thereby enhancing cleaning efficiency and reducing fluid change time.

Implementation Method 1

the cleaning fluid is introduced at one end of the core and then supplied into the sponge roller through holes communicating between the hollow portion and the outer surface of the core, and then flows out onto the outer surface of the sponge roller

AI summary

A core for a cleaning sponge roller and a cleaning sponge roller set include a core and a cleaning sponge roller mounted on the core. The core for the cleaning sponge roller is in a substantially cylindrical shape including a bore extending in an axial direction and a plurality of small holes communicating between the bore and a circumferential outer surface of the core. The diameter of the bore is 10 mm or more. The diameter of the small holes is 2.5 mm or more. A total of cross-sectional areas of openings of all the small holes is larger than a cross-sectional area of the bore.
