Innovation Solution
A sensor mounting system with a pot-like end section for secure sensor retention, wireless communication for power and data transmission, and retaining means to prevent accidental detachment, reducing manual handling and ensuring a sealed environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensors are mounted in immersion assemblies with detachable cables, then cable replacement is possible, but the assembly becomes complex and requires complicated dismantling procedures
Solution Approach 1:
The immersion assembly is divided into separate functional components: a sensor holder unit that remains fixed in the basin and a sensor unit with cable that can be independently removed and replaced. This segmentation allows cable replacement without dismantling the entire assembly, reducing complexity while maintaining adaptability.
Solution Approach 2:
The cable and sensor unit are extracted as a separate removable component from the immersion assembly. The sensor holder remains in the basin while the sensor unit can be detached for maintenance or replacement, simplifying the overall assembly structure while enabling cable replacement capability.
2Device complexity
If sensors are mounted in immersion assemblies with fixed cables, then assembly complexity is reduced, but cable replacement becomes impossible
Solution Approach 1:
The immersion assembly is segmented into a permanent sensor holder and a removable sensor unit containing the cable. This allows the assembly to maintain simplicity in installation while enabling cable replacement through the removable sensor unit design.
3Ease of repair
If manual handling of contaminated assemblies is required for sensor maintenance, then sensor replacement is possible, but infection risk and cleaning complexity increase
Solution Approach 1:
The sensor unit is extracted as a self-contained removable component that can be easily detached from the immersion assembly. This allows rapid removal and replacement of sensors without complex dismantling procedures, minimizing manual handling time and reducing infection risk while maintaining ease of repair.
4Reliability
If the assembly is sealed only when sensor is installed, then fluid-tight connection is achieved, but the interior can become contaminated when sensor is removed or incorrectly installed
Solution Approach 1:
The sensor holder is pre-configured with sealing elements and retaining structures that automatically create a fluid-tight seal when the sensor unit is inserted. The sealing action occurs before the sensor is fully operational, ensuring contamination prevention from the moment of installation. The retaining means pre-prepared in the sensor holder ensure proper positioning and sealing.
5Ease of repair
If the cable needs to be bent to install or remove sensor from assembly, then sensor replacement is possible, but cable damage and wear increase
Solution Approach 1:
The sensor unit with cable is extracted as a complete removable assembly. The cable is routed and secured within the sensor unit housing, allowing the entire sensor-cable assembly to be removed as one unit without bending or stress on the cable. This maintains cable durability while enabling easy sensor replacement.
