Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If thermocouples are installed in the hose wall to measure temperature, then temperature detection is enabled, but the installation becomes complicated and only point-specific measurements are obtained rather than averaging over the hose length
Solution Approach 1:
The patent combines multiple temperature sensing points into a single integrated sensor element that spans the hose length. The sensor integrates multiple thermocouple junctions along its length, allowing simultaneous measurement at multiple locations while providing an averaged temperature reading, thus eliminating the need for separate installations while improving measurement representativeness.
Solution Approach 2:
The integrated sensor serves multiple functions: it provides temperature measurement across the entire hose length, averages the temperature distribution, and can be installed as a single component. This multi-functional approach replaces what would otherwise require multiple separate sensors and complex installation procedures.
2Measurement precision
If RFID chips with temperature sensors are integrated into the hose wall, then temperature monitoring is enabled, but the integration becomes difficult and the chips represent weak points for cracks
Solution Approach 1:
The patent extracts the temperature sensing function from complex integrated circuits (RFID chips) and implements it using simpler, more compatible materials and methods. By using conductive elements that can be directly embedded in the hose matrix during manufacturing, the solution eliminates the need for post-manufacturing integration of complex electronic components.
Solution Approach 2:
The sensor material is selected to match the local properties of the hose wall, ensuring mechanical compatibility and structural integrity. The conductive elements are chosen to have similar mechanical properties to the surrounding material, preventing them from becoming weak points while maintaining temperature sensing capability.
3Measurement precision
If multiple temperature sensing devices are connected to different adapters, then temperature measurement is enabled, but the device complexity increases and operation becomes more complicated
Solution Approach 1:
The patent merges multiple temperature sensing functions into a single integrated sensor element that provides averaged temperature measurement across the hose length. This eliminates the need for multiple separate sensing devices and their corresponding adapters, simplifying both the hardware configuration and operational procedures.
