Solution Overview

Problem

Current mouthguards are expensive, unpleasant to wear, difficult to breathe through, and can be aesthetically displeasing, leading to reduced usage and increased risk of mouth injuries.

Innovation Solution

An interchangeable mouth shield design comprising a lip-anterior portion and a teeth tray that can be easily coupled and decoupled, allowing users to replace individual components, features customizable panels, and includes vents for easier breathing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional mouthguard is used to protect teeth and mouth area, then protection is provided, but the cost of replacement is high and aesthetic appearance is poor

Engineering Contradiction:
Improvemouth protectionVSAvoidreplacement cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The mouthguard is divided into two separate components: a lip-anterior portion and a teeth tray. The lip-anterior portion includes a shield and panel that can be detached from the teeth tray through a coupling mechanism. This segmentation allows users to replace only the lip-anterior portion when damaged or worn, rather than replacing the entire mouthguard, thereby reducing replacement costs while maintaining protection.

Inventive Principle:
Principle #1Segmentation

2Reliability

If a traditional mouthguard is used to protect teeth and mouth area, then protection is provided, but the taste is unpleasant and breathing is difficult

Engineering Contradiction:
Improvemouth protectionVSAvoidbreathing ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The lip-anterior portion includes a panel with multiple vents positioned at specific locations to facilitate breathing. The panel can be customized with different vent configurations, shapes, and decorative features. This local quality approach allows the mouthguard to provide protection while enabling users to breathe easily through the vents, addressing the breathing difficulty issue.

Inventive Principle:
Principle #3Local quality

3Reliability

If a traditional mouthguard is used to protect teeth and mouth area, then protection is provided, but the aesthetic appearance is poor causing embarrassment

Engineering Contradiction:
Improvemouth protectionVSAvoidaesthetic appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The lip-anterior portion is designed as a separate, detachable component that can be customized independently from the functional teeth tray. The panel can feature various shapes, team logos, animal profiles, text, and decorative elements. Users can choose different styles and designs to match their preferences, reducing embarrassment and increasing willingness to wear the mouthguard while maintaining protection.

Inventive Principle:
Principle #1Segmentation

4Reliability

If a traditional mouthguard is used to protect teeth and mouth area, then protection is provided, but the unpleasant taste and thirst are frequent

Engineering Contradiction:
Improvemouth protectionVSAvoidtaste comfort
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The lip-anterior portion includes a panel with specific surface characteristics that can be designed to reduce unpleasant taste and thirst. The panel material and surface treatment can be optimized locally to improve comfort during wear, while the teeth tray provides the primary protection function. This localized quality enhancement addresses taste comfort without compromising protection.

Inventive Principle:
Principle #3Local quality
