Solution Overview
Problem
Existing water analysis submersible probes with air flushing mechanisms have complex structures, making maintenance and repair expensive due to the need for disassembly and assembly, while also facing issues with fouling and clogging of electrodes.
Innovation Solution
A water analysis immersion probe design featuring a separate protective cap with an air outlet nozzle that sweeps over the electrode, allowing for simplified disassembly and assembly, and a detachable sensor cartridge for easy replacement of electrodes and consumables, utilizing a small annular and axial air duct system to minimize water ingress and facilitate maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air flushing is implemented to prevent fouling and clogging of electrodes, then electrode performance is maintained, but device complexity increases
Solution Approach 1:
The probe is divided into separable modules: a sensor cartridge containing the electrodes and a separate air flushing assembly. This segmentation allows the air flushing system to be independently attached and detached, reducing overall device complexity while maintaining electrode performance through continuous air flushing that prevents fouling and clogging.
Solution Approach 2:
The air outlet nozzle is extracted as a separate component from the main probe body, allowing it to be positioned optimally for sweeping air flow over the electrodes without integrating complex internal air channels into the probe housing. This extraction simplifies the main probe structure while preserving the anti-fouling function.
2Ease of repair
If the probe structure is simplified for easier maintenance, then ease of repair improves, but protective function may be reduced
Solution Approach 1:
The sensor cartridge is designed as a separable module that can be easily removed from the probe body without disassembling internal components. This segmentation enables quick replacement of electrodes and consumables, significantly improving ease of repair while the separate air flushing assembly maintains protective function by continuously clearing contaminants from the electrode surface.
Solution Approach 2:
The sensor cartridge with electrodes is designed as a replaceable unit that can be quickly swapped out when degraded, avoiding the need for complex maintenance procedures. This disposable-like approach to the sensor module simplifies repair operations while the durable probe body and air flushing system provide ongoing protection.
