Solution Overview

Problem

Existing hand-held cleaning and polishing tools lack a convenient and leak-proof mechanism for housing and applying both cleaning solutions and shoe polishing compounds efficiently, often resulting in unwanted leakage and inefficient application.

Innovation Solution

A hand-held applicator with two reservoirs, each containing a fluid conducting fiber, where one reservoir holds a cleaning solution and the other a shoe polishing compound, with modular designs and secure cap mechanisms to prevent leakage and ensure efficient application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing hand-held cleaning and polishing tools are used, then they can perform basic cleaning functions, but they lack a convenient and leak-proof mechanism for housing and applying both cleaning solutions and shoe polishing compounds, resulting in unwanted leakage and inefficient application

Engineering Contradiction:
Improveleak-proof mechanismVSAvoiddual reservoir structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The applicator is divided into two separate reservoirs (first reservoir for cleaning solution, second reservoir for polishing compound) with individual cap mechanisms. Each reservoir-cap assembly functions as an independent leak-proof unit, allowing the complex dual-functionality to be managed through modular, manageable segments rather than a single complex system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cap structures are designed to nest over the reservoir openings, with the cap body forming an outer shell that contains sealing elements. The seal engages with the reservoir opening to create a nested, leak-proof configuration that integrates multiple protective and sealing functions within a compact hierarchical structure.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If existing tools are used, then they are simple in structure, but they result in unwanted leakage and inefficient application of cleaning solutions and polishing compounds

Engineering Contradiction:
Improveefficient applicationVSAvoidcap and seal mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cap mechanism incorporates an integrated seal that automatically engages with the reservoir opening when the cap is placed on the reservoir. This self-sealing action eliminates the need for separate manual sealing steps, allowing users to simply cap the reservoir to achieve a leak-proof configuration. The spring-loaded or elastic seal components automatically adjust to ensure proper sealing without requiring user intervention.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If existing tools are used, then they can hold single substances, but they lack the capability to house and apply both cleaning solutions and shoe polishing compounds efficiently

Engineering Contradiction:
Improvedual substance capabilityVSAvoiddual reservoir system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The applicator device is designed with universal functionality to handle both cleaning solutions and polishing compounds through its dual reservoir system. Each reservoir is equipped with identical cap and seal mechanisms, allowing the same structural design to serve multiple purposes. The device can be used for both cleaning and polishing operations, making it a multi-functional tool that replaces the need for separate single-purpose applicators.

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