Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If trial-and-error medicament injection methods are used based on technician knowledge, then ease of operation is maintained, but manufacturing precision and measurement precision of medicament distribution deteriorate
Solution Approach 1:
The patent replaces manual trial-and-error injection methods with an automated system that uses imaging apparatus to visualize medicament distribution in real-time. The processing circuitry automatically calculates optimal injection parameters and controls the injection device, substituting human expertise with a systematic automated control mechanism that ensures precise medicament delivery to the tumor.
Solution Approach 2:
The system implements real-time feedback by using imaging apparatus to monitor medicament distribution during injection. The processing circuitry receives imaging data, compares it with the planned distribution, and adjusts injection parameters dynamically to achieve the desired medicament concentration in the tumor, creating a closed-loop control system.
2Device complexity
If trial-and-error medicament injection methods are used, then device complexity is reduced, but measurement precision and treatment planning accuracy deteriorate
Solution Approach 1:
The system integrates multiple functions into a unified platform: the imaging apparatus serves both for visualizing the tumor and monitoring medicament distribution, the processing circuitry performs both treatment planning and real-time control, and the injection device delivers both the medicament and provides feedback through integrated sensors. This multi-functional integration reduces overall system complexity while maintaining high measurement precision.
3Manufacturing precision
If personalized medicament administration plans are created using imaging data and processing circuitry, then manufacturing precision and treatment effectiveness improve, but device complexity and calculation requirements increase
Solution Approach 1:
The system segments the treatment process into distinct modular components: treatment planning module that creates the ideal medicament distribution, real-time control module that monitors actual distribution during injection, and adjustment module that modifies injection parameters on-the-fly. Each module handles a specific aspect of the complex task, making the overall system more manageable and less complex than a monolithic approach.
4Measurement precision
If real-time guidance for injection devices is provided, then ease of operation and measurement precision improve, but device complexity and operation time increase
Solution Approach 1:
The system performs preliminary treatment planning before the actual injection, where the processing circuitry calculates the optimal medicament distribution and determines the injection parameters in advance. This pre-planning phase creates a detailed roadmap that guides the real-time injection process, reducing the time and complexity required during the actual treatment execution.
