 And then coming back to a box, what are the critical issues of who collects letters from these boxes? We need to understand that person who collects letters because I am working on a letter box and we found out that it is the lowest division clerk, he is the lowest division in the whole post office circle and they go to collect the letters and they are very, very ingenious in finding out ways when the boxes are bad, when the locks do not open and we come down to those. Are you going to see why are the boxes different? Each country has a different box, a different requirement. Can you also check up the level of development in the country with the type of box they have? Could be, look at each of them, some of them are pedestals, some of them on the floor, some of them on legs, some of them have a single pedestal, some of them have double pedestals. Look at the last one, Hungary, they have the cast iron legs. Look at the other countries, Indonesia, then Italy, some of them are all uniform, one single monolith and they could be old. Look at Nepal, isn't it interesting? Concrete, quite nice. Each of them is very good, let them be older new because of the issue of their requirements, their current conditions and the type of vision the particular aspects have. Japan, that's not the right slide, I have the new box in Japan, maybe it's old, but they're old and new all put together, Spain, a round box still, this Spain and Europe you saw, most of them are similar to UK, their boxes are very, like, you know, very similar, that round pillar post box. So, understanding all this also gives us a lot of insights on what the country needs, so post boxes for the country. It also reflects your development, it also reflects whatever materials you're using, it also reflects your identity, because India post is part of the ministry, so you have a bigger mandate. So, we started with saying maintenance fee post box and now where have we reached? We reached the level of country saying that the identity of the country is at stake if you design a bad box, but this is important for us to understand the total gamut of the context from the users to the level of the government, to the level of the offices, to the level of people collecting the letters, so all those become our context. Now look at the product specific insights which I'll show you one by one. If you have a flat top, water will stay there and you will be having rusting. So, it's rusting, it leaks inside and the tags are all rusted. Look at the other aspects of the typical letter box, you know, the life is not even more than three years and when you paint some box like this again, you paint on top of the rust, so actually the rusting is happening inside and leakage is happening and even the installation processes are very, very tough. So, your installation costs are very high, the painting cost of the maintenance is very, very costly, so that also has very important bearing. And watering grace, look at this very, you know, ingenious postman, he actually put a gunny bag inside so that the letters don't get wet. Look at this, you know, water on the floor. Look at the other person where he's been a small hole over there, so the water goes and stays there rather than stay in the box. So, these are all the conditions of the post boxes. You'll have to ask me, did you solve all this? You'll have to be very smart now, you please keep observing all the problems and when we show you the ideas and the concepts, you people have to become critic and tell, ask me, is that solved? Okay, so that's the challenge. And look at the manufacturing effects. Can you see that edge which is open on the side? So, how do you manufacture? What are the details which you use for manufacturing? So, manufacturing plays a very vital role. So, from each of these insights, we're getting new, you know, aspects. Look at this design. They have a sheet on the top which is weak. So, it bends and that sheet, you know what's supposed to say? Anybody can guess? What's that sheet on the top which is bent is supposed to say? Direction to the post office and then they got themselves so confused that their post boxes came so many locations that finally that has been eliminated now. On the post box, we don't put direction of post box anymore. And look at this again, because the bottom is getting wet, the postman put a lot of sticks and wood so that the letter falls, it falls on those sticks so that you don't get, the letters don't get wet and look at the other problem. People putting cigarettes and stones inside. How do you prevent that? You can prevent all this. This is another big challenge. You have grass growing all around the post box. Your building is coming up next to your post box. So, what do you do in this cases? We're trying to make our box more and more better because we are studying all these aspects. Then look at this wall which has come next to the post box. So, what should I do with the post box and there's a wall like that next to it? I need to replace it and to put in a new location in a corner which is better. But now this can't be done because in this case, the post box is actually embedded 3 feet into the soil. I'll show you that design problem, installation issues. Look at that cage. All the cages inside, the soil, it's also again a formula for rusting. You put some mild steel inside soil, humidity and it can rust severely. Here you see people put a lot of posters on your boxes. How can you prevent that on your box? And what can you learn? There should be no projections because this electrical junction boxes is a projection which hurts people when they're walking on the street corners. So, a lot of these interesting things you see from other products can teach you what to do with your product.
