Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current handheld dental drills lack pressure indicators, leading to practitioners relying solely on experience to determine appropriate pressure, resulting in adverse consequences such as tooth breakage, pulp necrosis, and tool breakage during procedures.
Innovation Solution
A rotary instrument pressure indication system that includes a pressure sensor to monitor force applied and a feedback indicator to notify the user when the applied pressure reaches or exceeds a predefined threshold, providing visual, audio, or tactile feedback to prevent excessive pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If practitioners rely solely on experience to determine pressure, then device complexity is reduced, but manufacturing precision and reliability deteriorate due to lack of pressure control
Solution Approach 1:
The patent applies feedback by implementing a pressure sensor that continuously monitors the force applied through the rotary instrument and provides real-time feedback to the practitioner through visual, auditory, or tactile signals when a predefined pressure threshold is reached. This resolves the contradiction by maintaining simple device operation while achieving precise pressure control through automated feedback mechanisms.
Solution Approach 2:
The patent replaces the purely mechanical/experiential pressure determination method with an electronic sensing and feedback system. The pressure sensor electronically detects applied force and converts it into actionable feedback signals, substituting the practitioner's subjective experience with objective electronic measurement and control.
2Reliability
If pressure monitoring and feedback systems are added, then manufacturing precision and reliability improve, but device complexity increases
Solution Approach 1:
The feedback mechanism provides real-time pressure threshold alerts through multiple modalities (visual, auditory, tactile), enhancing procedural reliability by preventing excessive pressure application while maintaining a relatively simple device architecture through modular sensor and indicator components.
Solution Approach 2:
The pressure indication system is designed to be universally applicable across different rotary instruments and procedures. The feedback mechanism can operate through multiple channels (visual, auditory, tactile), allowing a single system to serve multiple functions and enhance reliability without proportionally increasing complexity.
3Productivity
If excessive pressure is applied, then productivity increases through faster tissue removal, but object-affected harmful factors worsen due to tissue damage and tool breakage
Solution Approach 1:
The pressure feedback system prevents excessive pressure application by alerting practitioners when the predefined threshold is reached, thereby avoiding tissue damage and tool breakage while maintaining optimal productivity through controlled pressure application throughout the procedure.
Solution Approach 2:
The system applies preliminary anti-action by establishing a predefined pressure threshold before the procedure begins and providing advance warning when this threshold is approached or exceeded. This preventive approach counteracts the tendency to apply excessive pressure for increased productivity before damage occurs.
4Loss of information
If pressure threshold alerts are implemented, then loss of information is reduced through better pressure awareness, but device complexity increases due to additional sensors and indicators
Solution Approach 1:
The feedback system eliminates loss of pressure information by providing real-time alerts when the predefined threshold is reached. The sensor and indicator components work together to convey critical pressure information to the practitioner, reducing information loss while maintaining manageable device complexity through targeted monitoring.
