Solution Overview
Problem
Current dental light irradiation devices lack the ability to independently adjust and maintain optimal positioning during the hardening process of dental materials, leading to potential inconsistencies in material hardening quality and durability.
Innovation Solution
A dental light irradiation device equipped with sensing means, such as photo diodes or cameras, to detect position changes and an indicator system, like vibrating alerts or visual feedback, to ensure consistent light exposure by alerting the user to reposition the device if necessary, thereby minimizing exposure time and intensity variability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual operation of the light device is used without position sensing, then the device is simple to operate, but the positioning precision and light exposure consistency deteriorate
Solution Approach 1:
The patent implements feedback by using sensing means (such as accelerometers or gyroscopes) to detect the position of the light device during operation, and using an indicator to provide real-time feedback to the user about position changes. This closed-loop feedback system enables precise positioning control without requiring complex manual operation, resolving the contradiction between measurement precision and device complexity.
2Manufacturing precision
If automatic position control is implemented, then the light exposure consistency is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent applies self-service by enabling the light device to automatically monitor and indicate its own position status through integrated sensing means. The device serves itself by detecting position changes and providing feedback without requiring external monitoring equipment or complex control systems, thus maintaining ease of operation while improving light exposure consistency.
3Reliability
If position sensing and indication systems are added, then the quality and durability of hardened dental materials is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical positioning systems with electronic sensing means (such as accelerometers, gyroscopes, or position sensors) that can detect and indicate position changes more reliably. This substitution reduces the mechanical complexity while improving the reliability of light exposure, thereby enhancing the quality and durability of hardened dental materials without proportionally increasing device complexity.
