Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If manual desensitization therapy is performed according to the 3-bag 12-step protocol, then the therapy can be administered, but nursing personnel are exposed to toxic drugs during dilution and replacement operations
Solution Approach 1:
The patent introduces an automated injection device as an intermediary between the toxic drug and the nursing personnel. The device performs all dilution and injection operations automatically, eliminating direct human contact with the toxic substance while maintaining the ability to execute the complex 12-step protocol.
Solution Approach 2:
The patent replaces manual mechanical operations with an automated pump-based system. The injection pump automatically performs dilution by controlling fluid flow rates and mixing ratios, eliminating the need for manual dilution operations that expose personnel to toxic drugs.
2Measurement precision
If manual adjustment of pump speed is performed to increase dose at each stage, then the injection rate can be controlled, but the operation is time-consuming and prone to errors
Solution Approach 1:
The automated injection device performs self-adjustment of injection rates through programmed control. The system automatically increases the dose at each stage according to the predetermined 12-step protocol without requiring manual intervention, thereby eliminating time loss and human error while maintaining precise control.
Solution Approach 2:
The patent implements automatic parameter changes in the injection rate according to the desensitization protocol. The control system dynamically adjusts pump speed and injection rate parameters at each of the 12 stages, transitioning from manual adjustment to automated parameter modification based on pre-set protocols.
3Loss of information
If manual recording of injection rate changes is performed, then the history can be documented, but the burden on nursing personnel increases
Solution Approach 1:
The automated injection device incorporates feedback mechanisms that automatically monitor and record injection rate changes at each stage. The system continuously tracks the injection history and stores it in memory, providing automatic documentation without requiring nursing personnel to manually record data, thereby eliminating the burden while preserving complete information.
4Manufacturing precision
If dilution is performed manually in a 3-bag system, then the protocol can be followed, but the concentration control accuracy is limited due to catheter volume and discharge line characteristics
Solution Approach 1:
The patent extracts the dilution function from the traditional 3-bag manual system and integrates it into a single automated injection device. By taking out the dilution operation and performing it internally within the device using precise pump control, the system achieves accurate concentration control while simplifying the overall setup and eliminating the need for multiple bags and manual mixing.
