Solution Overview

Problem

Patients post-oral surgery face discomfort and increased infection risk due to pain from contact with surgical sites during oral hygiene, which discourages adherence to necessary hygiene practices.

Innovation Solution

An oral shield system comprising a contoured molded body with extending wings and a flexible handle, allowing for adjustable positioning to prevent contact with surgical sites during brushing and flossing, featuring a detachable shield retainer assembly for versatile placement and easy replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If patients perform oral hygiene (brushing and flossing) to maintain good oral health and reduce infection risk, then oral hygiene quality improves, but pain and discomfort increase due to contact with surgical sites

Engineering Contradiction:
Improveoral hygiene adherenceVSAvoidpain from contact with surgical site
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The oral shield device serves as an intermediary barrier between the toothbrush/toothpick and the surgical site. The shield's contoured body with curved lower surface and extending wings physically blocks contact between hygiene tools and the vulnerable extraction area, allowing patients to continue oral hygiene routines without direct contact pain while maintaining hygiene effectiveness.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The oral shield is designed as a segmented protective structure with a main contoured body and separate extending wings that can be positioned between teeth. This segmentation allows the shield to fit into specific anatomical spaces and provide targeted protection at the surgical site while leaving other areas accessible for normal oral functions.

Inventive Principle:
Principle #1Segmentation

2Object-affected harmful factors

If patients avoid contact with surgical sites during oral hygiene to reduce pain, then pain decreases, but oral hygiene quality deteriorates

Engineering Contradiction:
Improvepain during oral hygieneVSAvoidoral hygiene maintenance
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The shield acts as a mediator that enables hygiene activities to proceed without compromising either pain reduction or hygiene quality. By positioning the shield before hygiene tools can reach the surgical site, patients can brush and floss other areas normally while the shield prevents harmful contact, maintaining both comfort and hygiene standards.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The shield introduces a spatial dimension to the oral hygiene process by creating a physical barrier in three-dimensional space. The contoured body and extending wings occupy specific volumetric space that blocks the path of hygiene tools, allowing hygiene to continue in other dimensions while protecting the surgical site.

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

3Object-affected harmful factors

If a protective barrier device is introduced to prevent contact with surgical sites, then protection from pain and infection improves, but device complexity increases

Engineering Contradiction:
Improveprotection from contact painVSAvoidoral device structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The oral shield utilizes a thin, flexible contoured body made from materials like silicone or thermoplastic elastomer. This flexible shell design provides effective protection while maintaining simplicity in structure and ease of insertion/removal. The thin-film nature reduces complexity compared to rigid multi-component systems while achieving the same protective function.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The shield employs a contoured body with a curved lower surface and arcuate wings that follow the natural curvature of the oral cavity. This spherical/curved geometry simplifies the design by using continuous surfaces rather than angular joints or multiple flat panels, reducing manufacturing complexity while providing optimal fit and protection.

Inventive Principle:
Principle #14Spheroidality (Curvature)

4Object-affected harmful factors

If a contoured shield structure is used to effectively block contact with surgical sites, then protection effectiveness improves, but manufacturing precision requirements increase

Engineering Contradiction:
Improveprotection effectivenessVSAvoidcontoured surface accuracy
Core Design Contradiction:
Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

The shield design uses parameter variations in the contoured body geometry, such as adjusting the radius of curvature of the lower surface and the angle of extending wings, to optimize protection effectiveness. These parameter changes are implemented through standard molding variations rather than requiring ultra-precise manufacturing tolerances, maintaining effectiveness while managing manufacturing complexity.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

By using flexible materials for the contoured body, the design tolerates moderate variations in manufacturing precision. The material flexibility allows the shield to conform to individual anatomical variations, compensating for minor dimensional tolerances in the molded shape while maintaining effective protection.

Inventive Principle:
Principle #30Flexible shells and thin films
