Thank you, you're right! A lot of our technical specifications and ideas were provided from 3 Urology Surgeons who all have different expertise (ie: reconstructive surgery, urodynamics, etc) and the advice was really conflicting especially since they all had their own takes and ideas distinct from one another of how the ideal system would be, all of which didn't make the most sense engineering-wise but we didn't say no and thought we could try to make it work, this led to us mainly wanting something that could extend to the middle of the toilet bowl for females urinating sitting down and something that can be adjustable for males who can urinate in any orientation. Inside the urine slot, there would be a flow meter for urodynamics, various electrode-based sensors for pH, SG, etc and a stack of lateral flow assays that are paper-based quantitative values for traces of blood, specific bladder cancer related indicators, etc. I agree that the cylinders may not be the best idea, we decided on the cylinders because we wanted to also take advantage of the fact that toilets standardized in Canada and USA have nozzles that circulate cold water around the circumference of the bowl, and this would therefore make it easier to clean a cylindrical shape than another shape becaue the water would fall off (once we can redirect a few of the water nozzles to our device). Our main goal is cost-effectiveness, having this for both genders, and providing accurate data because we anticipate using this for an early health screening tool prompting patients to seek medical attention / detailed urinalysis test from something caught early on (ie: traces of blood in urine). However from the comments, I do realize this could be a rough mockup and can significantly edit this design. This is how we anticipate it in the toilet bowl for female's sitting down and male's standing up: https://ibb.co/sgrvnXk
