A floating water quality measuring device that addresses the inability to move flexibly in response to changes in water levels and currents in sewage treatment plants, the risk of overturning and resulting accelerated sensor failure, and maintenance due to foreign substances attaching and adhering to the upper surface of the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the measuring device is fixed to a railing in the reaction tank, then the device structure is simple and easy to install, but the device cannot move flexibly in response to water level changes and water currents, causing overturning risk
Solution Approach 1:
The device transitions from a fixed structure to a dynamic floating structure that can move with water level changes. The floating body rises and falls with water levels, eliminating overturning risks while maintaining measurement accuracy.
Solution Approach 2:
A cable connection system acts as an intermediary between the floating body and the railing. The cable allows the floating body to move freely vertically while maintaining a connection to the fixed structure, enabling both adaptability and structural simplicity.
2Ease of repair
If the device is fixed in position, then installation is simple, but maintenance is difficult when foreign substances adhere to the upper surface
Solution Approach 1:
The floating body can be easily moved vertically along the cable to access different positions. For maintenance, the device can be raised to the surface where foreign substances can be removed, then lowered back to the measurement position.
Solution Approach 2:
The floating design allows the device to be easily accessed by operators who can manually remove foreign substances from the upper surface when the device is at the water level, enabling simple self-maintenance without complex retrieval mechanisms.
3Reliability
If the sensor is exposed to air due to overturning, then the device structure is simple, but the sensor fails more quickly
Solution Approach 1:
The floating body maintains a stable upright position dynamically through buoyancy forces, preventing overturning. The sensor remains continuously submerged and protected, ensuring reliable operation without exposure to air.
Solution Approach 2:
The floating design preemptively prevents overturning by allowing the device to move with water currents rather than resisting them. This eliminates the risk of the sensor being exposed to air before it can cause damage.
4Adaptability or versatility
If the device uses a floating structure, then the device can adapt to water level changes, but the device may be affected by water currents
Solution Approach 1:
The cable connection acts as a mediator that allows the floating body to move vertically with water levels while the railing provides lateral stability. This combination enables water level adaptability while mitigating water current effects through the anchored cable system.
