Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed sensor mount is used for pipes, then the sensor can be securely attached, but it cannot accommodate pipes of varying diameters
Solution Approach 1:
The sensor mount incorporates a dynamic bracket with adjustable positioning mechanisms that can adapt to different pipe diameters. The bracket includes movable components that allow the sensor to maintain secure contact with the pipe surface regardless of the pipe size, transforming a static fixed mount into an adaptable dynamic system.
Solution Approach 2:
The mount design allows for parameter changes in the bracket positioning and sensor orientation to accommodate varying pipe diameters. By adjusting geometric parameters such as bracket angle, distance from pipe surface, and sensor orientation, the system maintains reliable attachment across different pipe sizes without requiring multiple specialized mounts.
2Measurement precision
If the sensor is inserted into the pipe to measure fluid temperature, then accurate fluid temperature measurement is achieved, but potential leaks in the pipe are created
Solution Approach 1:
The sensor mount acts as an intermediary device that enables temperature measurement without direct sensor insertion into the pipe. By positioning the sensor on the external pipe surface through the bracket mechanism, the system mediates between the need for accurate fluid temperature measurement and the requirement to maintain pipe integrity, eliminating leak risks while preserving measurement capability.
Solution Approach 2:
The invention replaces the mechanical insertion method (which compromises pipe integrity) with a non-invasive external measurement approach. The sensor is mechanically positioned on the pipe exterior through the adjustable bracket, substituting the intrusive insertion mechanism with an external contact system that maintains pipe sealing while achieving temperature measurement through thermal conduction across the pipe wall.
3Reliability
If the sensor is positioned away from the pipe surface, then leak risks are reduced, but thermal coupling and measurement accuracy deteriorate
Solution Approach 1:
The bracket mechanism provides dynamic adjustment capability that allows the sensor to be positioned at the optimal distance from the pipe surface. This dynamic positioning ensures sufficient thermal coupling for accurate measurement while maintaining the safety margin needed to prevent leaks, adapting the distance parameter based on specific measurement requirements without compromising either reliability or precision.
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
The device provides precise temperature measurements by maintaining consistent contact pressure across varying pipe diameters, preventing leaks and ensuring accurate thermal coupling without direct contact between the sensor and the pipe, thus enhancing measurement accuracy.
Implementation Method 1
an elastic element (10), in particular a spring, is provided at the base of the bracket which exerts contact pressure on the tube (2, 3)
Implementation Method 2
the sensor is not inserted into the container of the medium, but only brought up to the outer surface of the container... to ensure good thermal coupling between the probe and the measurement object
