Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If a fluid delivery system with fixed capacity reservoir is used, then the device can provide interproximal cleaning functionality, but fluid usage efficiency is poor and frequent replenishment is required

Engineering Contradiction:
Improveworking fluid usage efficiencyVSAvoidtreatment effectiveness
Core Design Contradiction:
Loss of substanceVSProductivity

Solution Approach 1:

The system uses intraoral image sensors to automatically detect and locate interproximal gaps, and the controller automatically controls fluid delivery to these detected gaps. This self-service automation eliminates the need for user manual operation and ensures precise fluid application only where needed, improving both fluid efficiency and treatment effectiveness.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical operation with an automated system comprising image sensors, a trained classification algorithm for gap detection, and a controller that integrates image data with device positioning. This substitution of mechanical user operation with automated optical and computational systems enables precise fluid delivery without waste.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If manual operation is relied upon, then the device structure can be simple, but treatment accuracy and reliability are limited

Engineering Contradiction:
Improveinterproximal gap detection accuracyVSAvoiddevice structure complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The oral treatment device integrates multiple functions into a single system: intraoral imaging, image processing for gap detection, device positioning tracking, and fluid delivery control. This multi-functional integration achieves high measurement precision while managing device complexity through unified system architecture.

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

Solution Approach 2:

The patent introduces intraoral image sensors as an intermediary between the user and the treatment delivery system. These sensors capture optical images of the oral cavity, which are then processed by a classification algorithm to detect interproximal gaps. This intermediary enables accurate gap detection without requiring direct manual manipulation or complex mechanical positioning systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Quantity of substance

If the fluid reservoir capacity is increased, then fluid availability is improved, but device size and portability are compromised

Engineering Contradiction:

Core Design Contradiction:
Quantity of substanceVSVolume of moving object

Solution Approach 1:

The automated gap detection and targeting system ensures that working fluid is delivered precisely only to detected interproximal gaps, eliminating waste and reducing the total fluid quantity needed. This precision delivery mechanism allows the device to maintain small size while providing sufficient fluid capacity for complete treatment sessions.

Inventive Principle:
Principle #25Self-service
