• Choose of material should be acoording to user segment. I can use metal bands like right under the interface, and make it continue as a frame. Which I like this idea, cause as Semih Hoca said its also solve problem of that door cant open because of fillet radius. I tried to make it smaller yet I dont like its aesthetic aspect. So I decided to make metal etc. bands near the door radius to make it smaller. Those bands also can use for sealing by adding silicone inside, to provide isolation.
• For the mechanism of the doors, dividing doors in a half logical. And it can be foldable mechanism which fold the doors that divided half horzantaly. And sliding folded doors in to the unit will be suit my product language and give user to work area.
• I shoul look IKEA products for connection part, for assembly inspirations. It shouldnt have to demontage easly.
• For water container it can be placed in the mid and it shouldnt be that wide, I should define its for according to detailed usage scenario. I will make one water container. Also we discuse about the problem that fixing water container and matching it to the connection part( to transpass gas) Little snapfit details, lock systems, press and pull systems, rail systems can be used. Form should be matched to put container easly, I will work on it and create a internal detail here.
• And about root container, it can be hold gap under the container to direct user, I also examine it while considering detailed scenario.
• For platform, current system looks good I can developed further.
• And for seperators I can providing sealing and divide leds and heaters two. And make system understand that, so work as it. Yet I figure out horizantel dividing kinda hard because I dont have enough space also for roots. And I should create a part with leds etc.
• For the interface I should definately create a flow chart and decide what to show on device and on app, let which controllers to the user, where should be the notifications etc. On unit maybe user can activate interface with tapping two, pressing button etc and see the controllers. Maybe he wants to set a date, look conditions etc. Definately I should give codes to the units for matching via app to makes user understand easly which unit is which. Also I should definately remember that user wants to know which plant is which and it can be hard to understand in the growing period.
