Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a mechanical contact-based measuring system is used, then measurement can be performed, but the measured object and/or measuring instrument become contaminated with bacteria or other contaminants
Solution Approach 1:
The patent replaces mechanical contact-based measurement systems with optical measurement technology. The optical measuring instrument uses light to measure the inner diameter of the catheter without physical contact, thereby eliminating contamination while maintaining measurement capability.
Solution Approach 2:
The patent introduces light as an intermediary between the measuring instrument and the measured object. The optical measuring instrument emits light that reflects off the catheter surface, allowing measurement without direct mechanical contact and preventing contamination transfer.
2Measurement precision
If a mechanical measuring instrument is used, then measurement can be performed, but the measuring instrument itself becomes contaminated and requires cleaning or sterilization
Solution Approach 1:
The patent replaces mechanical measuring instruments that require cleaning and sterilization with optical measuring instruments. The optical system does not contact the measured object, eliminating the need for cleaning or sterilization procedures while maintaining measurement functionality.
3Object-affected harmful factors
If a non-contact optical measuring instrument is used, then contamination is avoided, but the instrument is more sensitive to environmental factors such as temperature, humidity, and pressure
Solution Approach 1:
The patent employs temperature compensation mechanisms that detect temperature changes and adjust measurement parameters accordingly. This allows the optical measuring instrument to maintain measurement accuracy despite environmental temperature variations, reducing the impact of environmental sensitivity.
4Object-affected harmful factors
If a non-contact optical measuring instrument is used, then contamination is avoided, but the device complexity increases
Solution Approach 1:
The patent designs the optical measuring instrument to perform multiple functions: measuring inner diameter, compensating for temperature effects, and potentially measuring other geometric parameters. This multi-functionality justifies the increased complexity by providing comprehensive measurement capabilities in a single device.
