Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If RFID technology is implemented to authenticate staple cartridge compatibility, then reliability is improved, but device complexity increases

Engineering Contradiction:

Improvecompatibility verification reliabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces manual verification methods with RFID technology, using electromagnetic fields to automatically detect and verify staple cartridge compatibility. The RFID scanner reads the unique identifier from the RFID tag embedded in the staple cartridge, eliminating the need for mechanical or manual compatibility checking mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The RFID tag in the staple cartridge automatically provides its identification information when queried by the scanner, enabling self-verification of compatibility without requiring external intervention or complex verification procedures by the user.

Inventive Principle:

Principle #25Self-service

2Reliability

If RFID tags and scanners are integrated into surgical instruments, then operational failures are prevented, but manufacturing complexity increases

Engineering Contradiction:

Improveoperational reliabilityVSAvoidmanufacturing ease

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The system is divided into separate functional modules: an RFID tag component that can be embedded in the staple cartridge during its manufacturing process, and a scanner component integrated into the surgical instrument. This segmentation allows each component to be manufactured independently using existing processes, reducing overall manufacturing complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The RFID scanner is designed to be a universal component that can be integrated into various surgical instruments, allowing the same scanning mechanism to verify compatibility across different device types. This multi-functionality reduces the need for custom-manufactured components for each specific instrument variant.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method for authenticating the compatibility of a staple cartridge with a surgical instrument is disclosed. The method can comprise inserting a staple cartridge into a surgical instrument, receiving a first signal from a first RFID tag on a first component of the staple cartridge with an RFID reader system, receiving a second signal from a second RFID tag on a second component of the staple cartridge with the RFID reader system, comparing the first signal and the second signal to stored data for a compatible staple cartridge, and locking a staple firing system of the surgical instrument if the first signal and the second signal do not match the stored data for a compatible staple cartridge.
