Solution Overview

Problem

Securing a high-quality scan with intraoral scanners is time-consuming due to the need for preparing the dental cavity before scanning, which can be inefficient and cumbersome for dental professionals.

Innovation Solution

A dental unit that provides an intraoral scanner with pressurized fluid, such as compressed air or water, to prepare the scanning area without the need for a multifunction syringe, enhancing scan quality and reducing process time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If intraoral scanner is used without integrated pressurized fluid delivery, then device complexity is reduced and ease of operation is improved, but scan quality deteriorates due to inability to effectively prepare the scanning area

Engineering Contradiction:
Improvescan qualityVSAvoidsystem complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent combines the intraoral scanner with integrated pressurized fluid delivery capabilities by incorporating fluid channels, nozzles, and control systems directly into the scanner housing. This merging allows the scanner to simultaneously perform scanning and fluid delivery functions, enabling effective preparation of the scanning area (drying, cleaning, or applying impression material) without requiring separate equipment, thereby improving scan quality while maintaining relatively simple operation through unified control.

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If traditional multifunction syringe is used to prepare the scanning area, then device complexity remains low, but process time increases and productivity decreases

Engineering Contradiction:
Improveworkflow efficiencyVSAvoidpreparation time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The integrated pressurized fluid delivery system performs preliminary preparation actions (drying, cleaning, or applying material) to the scanning area before the actual scanning process begins. The fluid can be delivered under pressure to quickly remove moisture or debris from tooth surfaces, ensuring the area is ready for scanning without requiring prolonged manual preparation with traditional syringes, thereby reducing preparation time and improving workflow efficiency.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system enables continuous useful action by allowing fluid delivery and scanning to occur in a more integrated and seamless manner. The pressurized fluid can be delivered continuously or in controlled bursts during the scanning process, eliminating the need to stop and switch between separate instruments, thereby maintaining continuous workflow and improving productivity.

Inventive Principle:
Principle #20Continuity of useful action

3Ease of operation

If pressurized fluid delivery is integrated into intraoral scanner, then ease of operation is improved by eliminating need for separate syringe, but device complexity increases

Engineering Contradiction:
Improveuser-friendlinessVSAvoidscanner complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The intraoral scanner is designed with multi-functionality by integrating pressurized fluid delivery capabilities into the existing device. The scanner can perform both scanning and fluid delivery functions through a single instrument, eliminating the need for dental professionals to switch between separate syringes and scanners. This universal design improves ease of operation and user-friendliness, allowing one device to handle multiple tasks that were previously required separate instruments.

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