Dental Handpiece Controller Rotation Direction Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dental treating apparatuses face challenges in distinguishing between clockwise-rotating and counterclockwise-rotating cutting tools, leading to incorrect driving control and potential unsafe treatment procedures.
Innovation Solution
A dental treating apparatus with a controller that automatically sets the appropriate rotation direction for the cutting tool based on identification information, allowing the user to operate the tool without determining its rotation direction, ensuring safe and proper cutting regardless of the tool's orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both clockwise-rotating and counterclockwise-rotating cutting tools are held on the head unit, then the apparatus can accommodate different cutting tool types, but the user cannot easily distinguish between them leading to potential operation mistakes
Solution Approach 1:
The patent applies visual marking (color coding) on the cutting tools to indicate their rotation direction. Different colors or patterns are applied to clockwise-rotating and counterclockwise-rotating cutting tools, allowing users to quickly distinguish between them without confusion, while maintaining compatibility with both tool types.
2Reliability
If the user manually determines the rotation direction of the cutting tool, then the user can select appropriate driving control, but this requires additional time and increases the risk of incorrect identification
Solution Approach 1:
The cutting tools are designed with self-identifying visual markings that automatically indicate their rotation direction to the user. The markings are inherently part of the tool design, allowing users to identify the correct rotation direction without requiring additional time for determination or external assistance, thereby improving both reliability and efficiency.
3Productivity
If incorrect driving control is applied to a cutting tool, then the apparatus can operate, but unsafe treatment may occur due to wrong rotation direction
Solution Approach 1:
The patent implements preliminary preventive measures by providing clear visual markings on cutting tools before use. These markings serve as advance warning and guidance to prevent incorrect operation. The visual identification system acts as a preliminary anti-action that stops potential harmful effects before they can occur by ensuring the user selects the correct rotation direction from the outset.

AI summary
The present invention is directed to a dental treating apparatus including: a hand piece; a power source (micro motor); a driving unit (motor driver); and a controller. The driving unit drives the cutting tool so as to be switchable between first driving in which the cutting tool is driven clockwise and second driving in which the cutting tool is driven counterclockwise. When a rotation direction in which the cutting tool cuts an object to be cut is defined as normal rotation and a rotation direction opposite to the normal rotation is defined as reverse rotation, the controller sets the first driving as driving for the normal rotation when a first cutting tool rotated clockwise is held on the head unit, and sets the second driving as the driving for the normal rotation when a second cutting tool rotated counterclockwise is held on the head unit.
