Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional CT imaging systems use rotating gantries with tightly controlled x-ray sources and detector arrays, then imaging precision and reliability are improved, but system weight, size, and installation complexity increase significantly
Solution Approach 1:
The patent divides the conventional integrated CT system into separate modular components: stationary x-ray sources, stationary detector arrays, and independently movable patient positioning systems. Each module can be installed and adjusted separately, reducing the weight and complexity of any single component while maintaining overall imaging precision through coordinated operation of multiple modules.
2Measurement precision
If conventional CT imaging systems use rotating gantries with tightly controlled x-ray sources and detector arrays, then imaging precision and reliability are improved, but device complexity and installation difficulty increase significantly
Solution Approach 1:
The system is segmented into independent functional modules (x-ray source modules, detector modules, positioning modules) that can be configured and installed separately. This modular architecture reduces overall system complexity by allowing each module to be optimized and tested independently before integration.
Solution Approach 2:
The patent designs universal mounting structures and standardized interfaces that allow the same modular components to be configured for different imaging applications and patient positions. The stationary modules can serve multiple functions through software control and positioning adjustments, reducing the need for specialized complex hardware for each application.
3Adaptability or versatility
If conventional CT imaging systems use rotating gantries, then comprehensive angular imaging coverage is achieved, but portability and adaptability to challenging environments are reduced
Solution Approach 1:
By separating the x-ray sources and detectors from the rotating gantry structure, each component becomes lighter and more portable. The system can be transported in smaller increments and assembled in environments where a complete rotating gantry could not be moved or installed.
Solution Approach 2:
The patent transitions from a single rotating gantry system to a multi-dimensional array of stationary sources and detectors. Imaging coverage is achieved through multiple angles simultaneously captured by distributed detectors rather than sequential rotation, enabling deployment in space-constrained environments.
4Ease of operation
If conventional CT imaging systems use rotating gantries, then comprehensive angular imaging coverage is achieved, but ease of installation and operation are reduced
Solution Approach 1:
The modular segmented design allows installation teams to work on individual modules separately rather than coordinating the assembly of a complex integrated gantry system. Each module has standardized mounting procedures and can be installed by smaller teams with less specialized training.
Solution Approach 2:
The system incorporates self-aligning mechanical features and automated positioning systems that reduce the need for complex manual alignment procedures during installation. Modules automatically calibrate their positions relative to each other, minimizing the technical expertise required for proper system setup.
