Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If temperature management therapy is delivered using multiple phases (induction, maintenance, rewarming), then the therapy can effectively control patient temperature, but the visualization of these phases becomes complex and difficult to analyze
Solution Approach 1:
The patent segments the temperature management therapy into distinct phases (induction, maintenance, rewarming) and visualizes each phase separately with uniform dimensions. This segmentation allows complex multi-phase therapy data to be broken down into manageable, comparable visual units that can be easily analyzed while maintaining complete therapeutic information.
Solution Approach 2:
The patent transforms the visualization from a traditional single continuous graph into a multi-dimensional layout where each phase occupies a separate uniform panel. This dimensional reorganization allows simultaneous presentation of multiple phases with equal visual weight, making it easier to compare and analyze different therapy stages without the complexity of a single overwhelming graph.
2Loss of information
If each phase of temperature management is visualized with different time scales to fit display, then the complete therapy timeline can be shown, but the phases cannot be easily compared
Solution Approach 1:
The patent applies local quality by allowing each phase panel to have its own optimized time scale while maintaining uniform overall dimensions. Each local panel can be tailored to best display its specific phase characteristics, yet the standardized layout enables easy comparison across all phases without sacrificing timeline completeness.
Solution Approach 2:
The patent changes the visualization parameter from a single continuous time scale to multiple discrete time scales, one for each phase. This parameter transformation allows each phase to be displayed with the most appropriate time scaling while the unified panel dimensions maintain ease of comparison across all phases.
3Duration of action of stationary object
If a single continuous graph is used to show the entire temperature management therapy, then the complete timeline is visible, but it becomes difficult to analyze individual phases
Solution Approach 1:
The patent segments the continuous therapy timeline into discrete phase panels (induction, maintenance, rewarming), each visualized separately but with uniform dimensions. This segmentation maintains complete timeline visibility while enabling focused analysis of individual phases without the overwhelming complexity of a single continuous graph.
Solution Approach 2:
The patent transitions from a one-dimensional continuous graph to a two-dimensional array of uniform phase panels. This dimensional change allows the complete therapy timeline to be preserved while organizing phases into a structured layout that facilitates easier detection and measurement of phase-specific characteristics.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables clear visualization of temperature management phases and power expenditure, facilitating optimized therapy delivery and post-case analysis, enhancing clinical decision-making.
Implementation Method 1
a heat exchange catheter is inserted into a blood vessel and a thermal exchange fluid is circulated through a heat exchanger positioned on the portion of the catheter that is inserted in the blood vessel. As the thermal exchange fluid circulates through the catheter's heat exchanger, it exchanges heat with blood flowing past the heat exchanger in the blood vessel.
Data Source
AI summary
In some implementations, data obtained by a temperature management system for delivering temperature management therapy to a patient is presented, within a single display region, as a graph of patient temperature over time representing the timespans of all phases of a multi-phase temperature management therapy. The graph may be fitted to present each phase separately in a manner that retains data complexity. The graph may include power data representing power output over time by a temperature management device. Data from other devices may be incorporated into the graph. A portion of the data may be patient temperature data and/or patient physiological data gathered during a time preceding temperature management therapy by the temperature management device.
