Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If needle tips are manufactured as separate disposable products for hygiene, then hygiene is guaranteed, but efficient management of needle tips becomes difficult
Solution Approach 1:
The patent applies the copying principle by implementing an NFC chip that creates a digital copy/representation of the needle tip's identity and information. The NFC chip stores unique identification information that replicates the physical needle tip's characteristics in a manageable digital format, allowing the handpiece to read and manage needle tip information without physical complexity
Solution Approach 2:
The patent replaces manual management mechanisms with an automated NFC-based identification system. Instead of physically tracking or manually recording needle tip information, the system uses wireless NFC communication to automatically read and manage needle tip data, substituting mechanical management processes with electronic automation
2Adaptability or versatility
If multiple types of needle tips are manufactured for different treatment purposes, then treatment versatility is improved, but inventory management becomes more complex
Solution Approach 1:
The NFC chip creates a digital copy of each needle tip's specification and type information, allowing the handpiece to instantly identify and manage different needle tip varieties. This digital representation enables efficient inventory tracking of multiple needle tip types without increasing physical management complexity
Solution Approach 2:
The system implements feedback by having the handpiece read NFC chip information and automatically manage needle tip inventory based on the retrieved data. The handpiece receives feedback about needle tip type and status, enabling automated inventory management that adapts to the specific needle tip being used
3Ease of operation
If needle tips are detachably mounted on handpiece, then needle tips can be replaced and mounted as needed, but authentication of genuine products becomes difficult
Solution Approach 1:
The NFC chip stores a digital copy of the needle tip's authentication information and unique identity. When the needle tip is detachably mounted, the handpiece reads this digital copy to verify authenticity, maintaining security despite the ease of physical replacement
Solution Approach 2:
The NFC chip is pre-loaded with authentication information before the needle tip is used. This preliminary action of embedding verification data allows the handpiece to authenticate the needle tip immediately upon mounting, ensuring genuine product verification is performed in advance before treatment begins
