Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a magnetic proximity sensor-based monitoring system is implemented, then remote monitoring capability and reliability during power outages are improved, but device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical float indicators with magnetic proximity sensors that detect liquid levels through magnetic fields. This substitution enables remote monitoring capabilities and maintains functionality during power outages, as the magnetic sensing mechanism operates independently of electrical power requirements for the core detection function.
Solution Approach 2:
The patent introduces magnetic fields as an intermediary between the liquid level and the sensing mechanism. Magnets are positioned at specific levels within the container, and magnetic proximity sensors detect their positions to indicate liquid levels. This intermediary approach enables non-contact, remote monitoring while maintaining system reliability.
2Ease of operation
If magnetic proximity sensors are used for remote monitoring, then ease of operation for distant observation is improved, but manufacturing complexity increases
Solution Approach 1:
The patent divides the monitoring system into separate functional components: magnets positioned at specific liquid levels within the container, magnetic proximity sensors for detection, and indicator mechanisms for remote observation. This segmentation allows each component to be manufactured independently using standard processes, reducing overall manufacturing complexity while enabling remote monitoring functionality.
Solution Approach 2:
The magnetic proximity sensor system serves multiple functions: it detects liquid levels, provides remote monitoring capability, and maintains operation during power outages. By using a universal sensing mechanism that combines these functions, the patent reduces the need for multiple separate systems, thereby simplifying manufacturing requirements.

AI summary
An apparatus for monitoring of a level of a liquid within a container, the apparatus comprising: at least one permanent magnet embedded within an attachment band disposed on the exterior wall of the container, or in a float disposed within said container and free-floating or immersed on said liquid, an electric circuitry comprising an electric power source, alarming device and at least one magnetic proximity sensor embedded respectively into the float disposed within said container and free-floating or immersed in the liquid or in the attachment band. The float moves laterally and vertically into and out of proximity of the attachment band, with variance of the level of the liquid, wherein the proximity of the float to the attachment band is sensed by the at least one magnetic proximity sensor, when the float is in close proximity to the attachment band, thereby activating the alarming device to notify a user/caregiver about possible depletion of liquid within the container.
