Solution Overview

Problem

Intra-oral scanners face challenges in effectively cleaning their tips to prevent disease transmission between patients, as existing designs often require aggressive cleaning methods that can damage components, and permanent attachments make replacement of individual parts difficult.

Innovation Solution

A tip for an optical scanner featuring a framework with a releasable attachment mechanism for the optical element, utilizing magnetic interaction or mechanical constriction, allowing for separate cleaning and replacement of components without damaging the tip or main body, enabling more aggressive cleaning of the framework while using gentler disinfection for the optical element.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the optical element is permanently attached to the framework using aggressive cleaning methods, then the framework can be thoroughly disinfected, but the optical element may be damaged

Engineering Contradiction:
Improvedisinfection effectivenessVSAvoidoptical element integrity
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The tip is divided into separable components: the framework and the optical element. The holding means allows the optical element to be detached from the framework, enabling independent cleaning of each component. The framework can undergo aggressive disinfection while the optical element receives gentler treatment, resolving the contradiction between thorough disinfection and optical element protection

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The holding means acts as an intermediary mechanism between the framework and optical element. It provides a controlled attachment that allows for deliberate separation and reattachment, facilitating different cleaning protocols for each component without permanent damage

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the optical element is permanently attached to the framework, then the attachment is secure, but replacement of individual parts becomes difficult

Engineering Contradiction:
Improveattachment securityVSAvoidcomponent replacement
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The holding means provides a dynamic attachment system that transitions between secured and replaceable states. During normal operation, the optical element is securely held in position. When maintenance is needed, the holding means allows for easy removal and reattachment of the optical element or framework, enabling flexible repair and replacement without permanent bonding

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

By segmenting the tip into separable components (framework and optical element) connected through the holding means, the design enables independent replacement of faulty parts. This segmentation maintains operational security during use while facilitating easy maintenance and repair

Inventive Principle:
Principle #1Segmentation

3Reliability

If the entire tip is replaced when one part needs replacement, then the functional integrity is maintained, but the cost and complexity increase

Engineering Contradiction:
Improvefunctional integrityVSAvoidreplacement complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The tip is segmented into replaceable modules (framework and optical element) connected through the holding means. This allows selective replacement of only the defective component rather than the entire assembly, reducing waste and cost while maintaining functional integrity through proper reattachment

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design enables recovery and reuse of functional components. When one part fails, the other component can be recovered, cleaned, and reused by detaching the faulty part through the holding means, thereby reducing overall device complexity and cost

Inventive Principle:
Principle #34Discarding and recovering
