Light Guide Pain Reliever Vibration and Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pain relievers for dental procedures, which rely on nitrous oxide and oxygen mixtures or retractors with vibrators, are not universally applicable and may not be feasible for all dental clinics, as they require specialized equipment or are limited to oral edge traction, failing to address patient anxiety and pain reduction in all treatment areas.
Innovation Solution
A light guide type pain reliever with a hollow handle, battery, pushbutton, vibrator, and light-emitting device, featuring a light guide plate that can be pressed on the affected area for accurate medication injection and to transmit vibrating waves, providing illumination and pain reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If nitrous oxide and oxygen mixture supply equipment is used to reduce patient anxiety and pain, then patient comfort is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the essential pain relief function from complex nitrous oxide equipment by using a simple vibrator mounted on a retractor handle. This eliminates the need for bulky gas supply equipment while maintaining the core benefit of pain reduction through vibration therapy during dental procedures.
Solution Approach 2:
The invention replaces expensive, complex nitrous oxide equipment with a simple, inexpensive retractor-vibrator combination that can be easily disposed of or replaced. This single-use or limited-use device provides effective pain relief without the high cost and complexity of reusable gas equipment.
2Object-affected harmful factors
If a retractor with vibrator is used to reduce pain through vibration, then patient pain is reduced, but adaptability to different treatment areas is limited
Solution Approach 1:
The patent enhances the retractor's functionality by integrating multiple components: the original retraction function, vibration delivery for pain relief, and illumination capability. This multi-functional design allows the single device to be effectively used across various treatment areas and procedures, not limited to oral edge traction only.
3Measurement precision
If illumination is added to improve visibility during treatment, then treatment precision is improved, but device complexity increases
Solution Approach 1:
The patent merges the illumination function with the existing retractor-vibrator device by integrating an light source and lens system into the handle. This consolidation provides improved visibility for accurate medication injection without requiring separate illumination equipment, thereby limiting the increase in overall device complexity.
