Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional display devices are used in ventilators, then device complexity is reduced, but operator visibility and ease of operation deteriorate due to insufficient qualitative and quantitative measurement data availability
Solution Approach 1:
The patent transitions from conventional one-dimensional numerical displays to two-dimensional graphical representations. Measurement data are visualized using geometric elements (circles, squares, triangles) positioned in spatial relationships that represent physiological connections. This dimensional enhancement allows operators to perceive multiple parameters simultaneously with improved qualitative and quantitative visibility while maintaining comprehensive data availability.
Solution Approach 2:
The patent creates visual copies of physiological structures (lungs, airways) using geometric elements that replicate the anatomical relationships. These graphical copies allow operators to intuitively understand measurement data in the context of the actual physiological system, improving ease of operation without losing measurement data availability through enhanced visual representation.
2Ease of operation
If animated graphical representations are added to ventilator displays, then operator visibility and ease of operation improve, but device complexity increases
Solution Approach 1:
The patent implements animated graphical representations where geometric elements dynamically change position, size, and configuration based on real-time measurement data. The display automatically updates to reflect physiological changes, providing intuitive visual feedback that improves ease of operation. The animation complexity is managed through standardized geometric transformations rather than complex graphical processing.
Solution Approach 2:
The graphical display system serves multiple functions simultaneously: it visualizes multiple measurement parameters, represents physiological relationships, provides real-time monitoring, and alerts operators to abnormal conditions. This multi-functionality is achieved through a unified geometric element system that can represent different parameters using the same visual language, reducing overall device complexity despite the enhanced capabilities.
3Loss of information
If multiple measurement parameters are visualized simultaneously, then loss of information is reduced, but device complexity increases due to additional processing requirements
Solution Approach 1:
The patent segments measurement data into distinct geometric elements, with each parameter represented by a separate geometric shape or position. This segmentation allows multiple parameters to be visualized simultaneously without creating processing complexity, as each element can be independently generated and updated based on its corresponding measurement data stream.
Solution Approach 2:
The patent applies different visual properties (geometric shapes, positions, sizes) to different measurement parameters based on their local characteristics and physiological significance. This local differentiation allows the system to efficiently process and display multiple parameters simultaneously by tailoring the visual representation to each parameter's specific requirements rather than using a uniform display approach.
