Best Ideas 2020 features all the nominated entries submitted under ‘Submit your Idea’ category. All the entries consist of innovative solutions or propositions for an enterprise that champions the Sustainable Development Goals. They can be on the conceptual, planning, or start-up stage.
Ultrasonic sterilization of hospital rooms using optical droplet detection
Explain your idea in details:
The proposed idea aims in sterilizing the hospitals (not only in Corona pandemic but also in general terms) keeping in mind the parameters like accuracy, cost, efficiency, ease of usability and fabrication. Since experiments conduct shows that UV and liquid disinfectants are not efficient with Corona virus as it is not airborne. The above conducted activities helped us to know the demand and the unique value proposition of our product. The market segmentation helped us to know the competitors or our product and how we are different from them. Simulation results helped us to know the possible functionality of the product and the way in which we can improvise them. Some of the challenges and the ways we overcome that are listed below. 1. Ultrasonic is harmful:Ultrasonic above 120 decibels are only harmful. The product works only in the range of 80 to 85 decibels. 2.Technical issues:If the device crosses 120 decibels due to technical issues, the product operates on a tuner device and hence it will automatically shut down the device if the emitter crosses the threshold values. 3.Powering up and cost:Since the product is established through IOT concepts along with image processing and machine learning, the cost of sensors and powering them up are way too easier and cheaper. 4. How to know if the waves are getting generated or not? A simple ultrasonic detector will be implemented which can tell if the waves are generated or not. 5. Dissipation of rays:Ultrasonic rays are self dissipated once the power to the source is cut off. 6.How to know if the room is sterilized? If the thermal imager shows grey regions, it means there are contaminated regions. If the grey regions are turned to green, it means the waves have sterilized the regions.
Expected impact of your idea on sustainable development
We conducted silicone powder experiment to prove that ultrasonic waves are better than UV rays. We observed that the ultrasonic waves were able to agitate the silicone powders and they got destroyed in 5 femtoseconds. On the other hand, we used UV and found out that only 34 percent of the silicone powders got destructed. We target hospital and medical industries. We claim to have achieved success if the device is able to detect the contaminated droplets and agitate it effectively.
Plans for implementation and sustainability
Technical plan: Concept --> Functional prototype --> Minimum viable product --> Market viable product --> Testing --> Iterations Business plan: Franchises --> Medical industries --> Hospitals We are still looking for funding and grants to take this idea forward.
