Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If calibration is performed for each optical element when tip unit is replaced, then measurement accuracy is improved, but measurement process complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-storing calibration parameters for each optical element in a database before actual measurement. When a tip unit is replaced, the system automatically retrieves the corresponding calibration parameter based on identification information, eliminating the need for real-time calibration procedures and simplifying the measurement process while maintaining accuracy.
2Measurement precision
If calibration parameter is obtained every time tip unit is replaced, then measurement accuracy is improved, but measurement time increases
Solution Approach 1:
The patent applies preliminary action by pre-storing calibration parameters for each optical element in a database before actual measurement. When a tip unit is replaced, the system automatically retrieves the corresponding calibration parameter based on identification information, eliminating the need for real-time calibration procedures and reducing measurement time while maintaining accuracy.
3Measurement precision
If individual calibration for each optical element is performed, then measurement accuracy is improved, but device operation complexity increases
Solution Approach 1:
The patent applies self-service by enabling the main body unit to automatically identify the attached tip unit through identification information and autonomously retrieve the corresponding calibration parameter from the database. This automated process eliminates manual calibration operations, allowing users to simply attach the tip unit and start measurement without complex procedures.
4Reliability
If tip unit is made detachable for sterilization, then hygiene reliability is improved, but system complexity increases
Solution Approach 1:
The patent applies universality by designing the tip unit with integrated identification information that serves multiple functions: enabling sterilization through detachability and facilitating automatic calibration parameter retrieval. This multi-functional design allows the same identification mechanism to support both hygiene requirements and measurement accuracy without adding separate systems.

AI summary
An object is to provide a dental measurement apparatus, a tip unit of the dental measurement apparatus, and a dental measurement system, which make it possible to obtain an accurate measurement value in consideration of an influence of each individual optical element. A probe (10) is provided with identification data (15), and a reading unit (32) of an optical measurement unit (30) reads the identification data (15) and a control unit (42) of a control device (40) reads management data (330) corresponding to the identification data (15) from a server (300). The control unit (42) calibrates an actual measurement value based on calibration data (331) of the management data (330).
