Solution Overview

Problem

Dental light irradiation devices with integrated cameras face challenges in providing user-friendly operation for both curing and visualization functions, particularly in environments without a display, and existing devices often require complex user inputs or restrict functionality based on mode selection.

Innovation Solution

A dental light irradiation device with a first light source for emitting blue light, a camera, and detectors that allow operation in both camera and non-camera modes, enabling optional camera activation via user input, and featuring a sleep mode that activates non-camera mode upon inactivity, with customizable cure operations and image capture instructions for real-time or frozen image transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a camera is integrated into the dental light irradiation device, then visualization function is improved, but device complexity increases

Engineering Contradiction:
Improvevisualization functionVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device integrates multiple functions (curing and visualization) into a single dental light irradiation device, allowing the same device to serve both as a light source for hardening dental materials and as an imaging device for capturing intraoral images, thereby improving versatility without proportionally increasing complexity

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

2Adaptability or versatility

If camera mode is always activated, then visualization is always available, but battery power is consumed continuously

Engineering Contradiction:
Improvevisualization availabilityVSAvoidbattery power consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The device dynamically switches between camera mode and non-camera mode based on user input and operational context, allowing the camera to be activated only when needed for visualization while remaining deactivated during curing operations to conserve battery power

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The camera function is activated periodically or on-demand rather than continuously, with the ability to switch between modes based on operational requirements, reducing overall energy consumption while maintaining visualization capability when needed

Inventive Principle:
Principle #19Periodic action

3Loss of energy

If camera mode is restricted to specific conditions, then battery is conserved, but user flexibility is reduced

Engineering Contradiction:
Improvebattery conservationVSAvoiduser flexibility
Core Design Contradiction:
Loss of energyVSEase of operation

Solution Approach 1:

The operational modes are dynamically adjustable based on user input, allowing the device to adapt between camera mode and non-camera mode freely without rigid restrictions, providing both battery conservation and user flexibility through on-demand mode switching

Inventive Principle:
Principle #15Dynamics

4Adaptability or versatility

If user input is required for mode switching, then camera activation is controlled, but operation complexity increases

Engineering Contradiction:
Improvecamera activation controlVSAvoidoperation simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The device automatically determines when to activate camera mode based on detected operational context, reducing the need for explicit user input while maintaining controlled camera activation through intelligent detection of curing versus visualization scenarios

Inventive Principle:
Principle #25Self-service

AI summary

A dental light irradiation device has a first light source for emitting blue light, a camera and at least a first detector. The device is operable in a camera mode in which the camera is activated and in a non-camera mode in which the camera is deactivated. In the non-camera mode a user input on the first detector activates the camera mode. The dental light irradiation device helps facilitating the proper curing of a dental material in a patient's mouth.
