Summary of the Inventive Concept

Retrofittable sensor units tailored for high-security, disaster relief, and extreme weather conditions, enabling optimal detergent dosing in specialized washing machines.

Background and Problem Solved

The original patent disclosed a retrofittable sensor unit for controlling a dosing device in a cleaning machine. However, this invention had limitations in addressing the unique requirements of high-security, disaster relief, and extreme weather conditions. The present inventive concept adapts the original sensor unit to cater to these niche markets, providing enhanced security, reliability, and energy efficiency.

Detailed Description of the Inventive Concept

The inventive concept comprises retrofittable sensor units with tailored components and configurations for high-security, disaster relief, and extreme weather conditions. For high-security environments, the sensor unit features a detection area conforming to a recess in the housing, accommodating microcameras and a viscosity sensor, and transmits dosing commands via a secure communication protocol. For disaster relief washing machines, the sensor unit is powered by an energy harvesting system adapted for extreme weather conditions and transmits dosing commands based on the captured condition of the washing solution. For extreme weather conditions, the sensor unit features a weather-resistant housing, a viscosity sensor, and a turbidity sensor, and transmits dosing commands via a satellite communication system.

Novelty and Inventive Step

The inventive concept's novelty lies in its adaptation of the original sensor unit to address the specific requirements of high-security, disaster relief, and extreme weather conditions. The inventive step resides in the tailored components, configurations, and communication protocols that enable optimal detergent dosing in these niche markets.

Alternative Embodiments and Variations

Alternative embodiments may include sensor units with additional sensors for measuring thermal variables, calorific measurement variables, or other parameters relevant to the specific application. Variations may also include different communication protocols, energy harvesting systems, or housing designs to suit specific operational environments.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the specialized washing machine market, particularly in high-security facilities, disaster relief operations, and extreme weather conditions. Target industries may include government agencies, disaster relief organizations, and companies operating in extreme weather environments.
