Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional surgical devices (burs and saws) are used for bone cutting, then bone removal capability is achieved, but sound and vibration signals are uncontrollable and imprecise
Solution Approach 1:
The patent applies mechanical vibration by integrating a vibration generator that produces controlled vibrational signals during bone cutting. This allows the system to generate precise, controllable sound and vibration signals for analysis, transforming the previously uncontrollable vibration into a useful measurement tool for detecting breakthrough events and characterizing bone properties.
Solution Approach 2:
The patent implements feedback by using the generated sound and vibration signals to monitor the bone cutting process in real-time. The signals provide information about the cutting status, bone layer transitions, and potential breakthrough events, enabling the system to feedback control the cutting process and alert the surgeon to adjust parameters or stop cutting to prevent tissue damage.
2Ease of operation
If bone cutting is performed to remove bone, then surgical access is achieved, but soft tissues may be damaged due to limited visual access
Solution Approach 1:
The patent uses sound and vibration signals as feedback to monitor the cutting depth and bone layer transitions. When the cutting tool approaches soft tissues or enters bone channels, the signal characteristics change, providing real-time feedback to the surgeon to adjust or stop cutting, thereby preventing soft tissue damage while maintaining surgical access.
Solution Approach 2:
The patent introduces sound and vibration signals as an intermediary between the cutting tool and the surgeon's decision-making process. These signals serve as a mediator that provides information about the cutting status and tissue boundaries, enabling the surgeon to navigate safely through bone structures without direct visual access to the cutting zone.
3Productivity
If conventional devices are used, then bone cutting is achieved, but transient and multi-factor-dependent signals are produced
Solution Approach 1:
The patent generates controlled mechanical vibrations through an integrated vibration generator, producing stable and reliable sound and vibration signals during bone cutting. This controlled vibration approach ensures consistent signal production regardless of cutting speed or bone density variations, improving signal reliability while maintaining cutting efficiency.
Solution Approach 2:
The patent changes the parameters of signal generation by using a controlled vibration generator with adjustable frequency and amplitude. This allows the system to produce standardized signals that are not dependent on cutting parameters or bone properties, ensuring reliable and reproducible measurements throughout the surgical procedure.
