Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If radiographers rely on subjective experience for positioning operations, then the operation process can be performed manually, but there is a lack of objective evaluation and measurement tools leading to potential positioning errors
Solution Approach 1:
The patent introduces a camera as an intermediary device to capture the positioning state of the patient, and a processor as an intermediary system to analyze the captured image and calculate positioning parameters. This intermediary measurement system provides objective evaluation without requiring complex manual measurement tools, resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The patent replaces manual mechanical positioning evaluation with an automated image processing system. Instead of relying on radiographers' subjective experience and manual measurement, the system uses camera imaging and automated image analysis to objectively measure positioning parameters, thereby improving measurement precision while keeping the added complexity manageable through software-based solutions.
2Adaptability or versatility
If there are a large number of body positions requiring positioning, then comprehensive positioning coverage can be achieved, but it becomes difficult for radiographers to ensure all aspects meet positioning standards
Solution Approach 1:
The patent implements a feedback mechanism where the system captures the patient's positioning state via camera, processes the image to determine positioning parameters, and provides real-time feedback to the radiographer. This feedback loop enables radiographers to quickly verify and adjust positioning for various body positions, making comprehensive positioning coverage achievable while maintaining operational ease through automated guidance.
Solution Approach 2:
The patent develops a universal positioning evaluation system that can handle multiple body positions and imaging types through a single integrated platform. The system uses generic image processing algorithms and a unified camera-based approach that works across different examination scenarios, thereby achieving comprehensive versatility without proportionally increasing operational complexity.
3Reliability
If positioning requirements are strictly enforced to prevent incomplete coverage or excessive radiation, then imaging quality and patient safety improve, but the complexity of ensuring compliance increases
Solution Approach 1:
The patent enables the positioning system to self-evaluate and self-verify compliance with positioning standards. The camera captures the positioning state, the processor automatically calculates positioning parameters, and the system compares these against required standards to determine compliance. This self-service capability improves reliability of positioning standard compliance while avoiding the need for complex external verification systems.
