Solution Overview

Problem

Existing devices for cleaning large-diameter balls, such as soccer balls, are expensive and inefficient, with previous methods failing to completely remove dirt from all surface areas due to limited cleaning mechanisms that often result in uncleaned strips and stress on the ball surface.

Innovation Solution

A device featuring a housing with rotating cleaning elements, covered with a segmented cleaning layer of bristle or microfiber material, which provides chaotic movement to ensure thorough cleaning, combined with injection nozzles for cleaning agents and a system for water management, allowing for effective cleaning of all ball surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If washing water emerges from nozzles or bores, then cleaning process is simple, but cleaning is insufficient and uncleaned strips remain on ball surface

Engineering Contradiction:
Improvecleaning mechanism simplicityVSAvoidcleaning completeness
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The cleaning layer is divided into multiple segments arranged around the cleaning element's circumference. Each segment can be independently positioned to create varying cleaning patterns as the cleaning element rotates, ensuring complete coverage of the ball surface without leaving uncleaned strips.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cleaning elements rotate around the ball in one dimension while the segmented cleaning layers create motion in another dimension through their radial positioning. This multi-dimensional cleaning action ensures all surface areas of the ball are cleaned effectively.

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

2Device complexity

If ball rotates evenly in two dimensions, then cleaning mechanism is simple, but uncleaned strips remain on ball surface

Engineering Contradiction:
Improvecleaning motion simplicityVSAvoidsurface coverage completeness
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The cleaning elements rotate at variable speeds rather than a constant speed. This dynamic rotation creates chaotic motion patterns that prevent uncleaned strips from forming, ensuring complete surface coverage while maintaining a relatively simple mechanical structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The cleaning elements undergo periodic rotation with varying speeds and directions. This periodic action ensures that different segments of the cleaning layer contact different areas of the ball surface over time, achieving complete cleaning coverage.

Inventive Principle:
Principle #19Periodic action

3Ease of operation

If traditional cleaning devices are used, then cleaning function is provided, but device cost is high and cleaning is insufficient

Engineering Contradiction:
Improvecleaning functionalityVSAvoiddevice cost
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cleaning system uses the ball's own rotation and the rotating cleaning elements to achieve cleaning without requiring complex external mechanisms. The segmented cleaning layers and variable speed rotation create effective cleaning action through the interaction between the ball and cleaning elements themselves.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The cleaning elements use replaceable cleaning layers that can be easily renewed rather than requiring expensive, complex mechanical structures. This approach reduces device cost while maintaining effective cleaning functionality.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
