Root Canal Treatment Unit with External Diagnostic Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional treatment units for medical and dental purposes are oversized and heavy due to their complex structure, which impairs operability and increases the footprint, making them less efficient for medical care.
Innovation Solution
The treatment unit offloads diagnostic functions to an external unit, with diagnostic information displayed on the same display as driving information, using a simplified structure and lightweight display technologies like liquid crystal, organic EL, or electronic paper to reduce size and weight, allowing for flexible operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If diagnostic functions are integrated into the treatment unit, then diagnostic capability is improved, but device complexity and size increase
Solution Approach 1:
The system is divided into two independent parts: a treatment unit for curative treatment and an external diagnostic unit for diagnosis. The treatment unit includes a treatment tool and control unit, while the diagnostic unit separately performs measurements and transmits data. This segmentation allows each unit to be optimized for its specific function without the complexity burden of integrating all functions into one device.
Solution Approach 2:
The display unit serves multiple purposes: it displays driving information about the treatment unit itself and simultaneously displays diagnostic information received from the external diagnostic unit. This multi-functionality allows comprehensive information presentation without adding separate display devices, maintaining simplicity while achieving versatility.
2Adaptability or versatility
If all functions are integrated into one unit, then functionality is improved, but weight increases
Solution Approach 1:
The diagnostic functions are extracted from the treatment unit and placed in a separate external diagnostic unit. This extraction removes the weight of diagnostic components from the treatment unit, making it lighter and more suitable for handheld operation, while the treatment unit still provides comprehensive functionality through integration with the external unit.
3Loss of information
If multiple display devices are used for different information, then information presentation is improved, but device complexity and size increase
Solution Approach 1:
The display unit combines multiple information streams into a single display interface. It simultaneously presents driving information about the treatment unit and diagnostic information from the external diagnostic unit, eliminating the need for separate display devices and reducing overall system complexity while maintaining comprehensive information availability.

AI summary
A treatment unit includes: a communication part that receives through a communication cable information about a root canal length acquired by a root canal length measuring unit as an external diagnostic unit; a display device on which the information about a root canal length is displayed; and a treatment unit body to which a file for root canal enlargement is attached. The treatment unit body forms a holding part held by a user. The display device is provided on the outer circumference of the holding part. The user can visually recognize a root canal length displayed on the display device while performing root canal enlargement with the treatment unit held by the user.
