Solution Overview

Problem

Current oral care implements, such as toothbrushes, are inadequate in effectively removing bacteria and microdebris from the tongue's soft tissue surfaces due to limitations in design and manufacturing, particularly in reaching tight spaces and providing comfort during use.

Innovation Solution

An oral care implement with multiple soft tissue cleaners of different densities, hardness, colors, and materials, including conically shaped nubs and elongated strips, strategically positioned on the head to cover various oral surfaces, providing enhanced cleaning and sensory responses, and manufactured using injection molding techniques to accommodate multiple components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a single elastomeric soft tissue cleaner is applied to the head, then manufacturing is simplified, but cleaning effectiveness in tight spaces and recesses is limited

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidcleaning effectiveness
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The soft tissue cleaner is divided into multiple separate components (first cleaner, second cleaner, third cleaner) that can be independently molded and then assembled on the head. This segmentation allows each component to be optimized for specific cleaning functions while maintaining manufacturing efficiency through modular production.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the head are equipped with cleaners having different properties (density, hardness, material composition) tailored to specific cleaning needs. For example, softer cleaners for sensitive areas and harder cleaners for tougher deposits, with each cleaner optimized for its specific location and function.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If multiple soft tissue cleaners with different properties are incorporated, then cleaning versatility and effectiveness are improved, but manufacturing complexity increases

Engineering Contradiction:
Improvecleaning versatilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cleaner system is segmented into multiple independent components that can be manufactured separately using standard injection molding processes, then assembled on the head. This reduces the complexity of any single manufacturing step while achieving overall system versatility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The head structure is designed with universal features (multiple injection ports, standardized mounting locations) that can accommodate different types of cleaners with different properties. This universal design allows a single head platform to support multiple cleaner configurations for different cleaning needs.

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

3Reliability

If cleaners with different densities and hardness are used, then cleaning effectiveness on various oral surfaces is enhanced, but material selection and manufacturing precision requirements increase

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidmaterial specification precision
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

Each cleaner component is assigned specific material properties (density, hardness, elastomer type) optimized for its particular location and function on the head. This local optimization allows different materials to be used in different regions without requiring uniform high-precision manufacturing across all components.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The invention utilizes variations in material parameters (density, hardness, elastomer composition) as the primary means of differentiation between cleaners. By controlling these material parameters during standard injection molding processes, the system achieves functional diversity without requiring complex manufacturing precision.

Inventive Principle:
Principle #35Parameter changes
