Solution Overview

Problem

Existing diving regulator mouthpieces require users to bite and tighten their teeth to retain the device, which can strain masticatory muscles and affect breathing efficiency, and customizable mouthpieces often require the same user to mold them, limiting reuse and precision.

Innovation Solution

A mouthpiece with a tubular connection and a bite portion that supports the entire upper dental arch, featuring a U-shaped cross-section and a hollowed central portion with a protruding border, allowing it to be securely wedged in the mouth without requiring biting, and can be customized using dental molds and 3D printing techniques.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the mouthpiece is retained by biting on lateral portions of dental arch, then the mouthpiece can be held in place, but masticatory muscles are strained and breathing efficiency is affected

Engineering Contradiction:
Improvemouthpiece retentionVSAvoidmasticatory muscle strain
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The mouthpiece is divided into distinct functional zones: a wide central portion that contacts the entire upper dental arch for primary retention, and lateral portions that extend toward the molars for secondary stabilization. This segmentation allows different regions to perform different retention functions, eliminating the need for masticatory muscle engagement while maintaining secure positioning.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The retention mechanism transitions from a one-dimensional lateral bite contact to a two-dimensional broad contact surface across the entire upper dental arch. The central portion's width and curvature are designed to engage multiple teeth simultaneously, distributing retention forces across a larger area and eliminating the need for vertical biting forces that strain masticatory muscles.

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

2Adaptability or versatility

If customizable mouthpieces are molded by the same user, then the mold can be permanent or deletable, but the process requires user precision and limits reuse

Engineering Contradiction:
ImprovecustomizabilityVSAvoiddental impression accuracy
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The mouthpiece is pre-formed with a deletable mold structure that can be easily reset. The deformable material is prepared in advance with specific thermal or mechanical properties that allow it to be softened and remolded multiple times. This preliminary preparation eliminates the need for users to achieve high precision during each molding attempt, as the material itself compensates for minor variations in user technique.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The mold's physical parameters (temperature, hardness, deformability) are changed to enable easy resetting. By controlling the material's thermal or mechanical state, the mold can transition between a rigid permanent form and a soft deletable form, allowing multiple customizations with consistent precision without requiring advanced user skill.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If the bite portion has a U-shaped cross section wrapping the teeth, then the mouthpiece gets stuck to the entire dental arch, but the structure becomes more complex

Engineering Contradiction:
Improvemouthpiece retentionVSAvoidbite portion geometry
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The U-shaped cross-section design merges the central portion and lateral portions into a single continuous structure that wraps around the entire upper dental arch. This unified geometry creates multiple contact points simultaneously, enhancing retention reliability without requiring separate components or complex assembly procedures.

Inventive Principle:
Principle #5Merging (Combining)
