Virtual Inventions

This essay is about a suggested student project in Java programming. This essay gives a rough overview of how it might work. It does not describe an actual complete program. I have no source, object, specifications, file layouts or anything else useful to implementing this project. Everything I have to say to help you with this project is written below. I am not prepared to help you implement it; I have too many other projects of my own.

I do contract work for a living, which could include writing a program such as this. However, I don’t do people’s homework for them. That just robs them of an education.

You have my full permission to implement this project any way you please.

The ideas in this essay are not computer projects, but ideas for inventions. You are free to run with them.

Writing on Polyethylene

You may have noticed there is problem with labelling objects made of polyethlene and similar plastics such as bottles and cleaning product sprayers. Paper labels come off. Embossed writing is almost impossible to read. The surface is slippery so inks, even permanent markers won’t stick to it. My solution to the problem is inspired by Cloisonné. You mould the white bottle with relatively deep wells for the lettering. Then you fill the wells with red liquid plastic, allow to harden, then polish to expose the precise well boundaries. The trick is to figure out how to make the process cheap and fast. You might just specialise in one thing, e.g. the little cap on a sprayer bottle you twist to various angles for spray, dribble and off and sell caps to all the big cleanser companies.

Sink Cleaning Supply Basket Basket

This is simply a basket with feet to raise it slightly out of pooled water. It has many small holes to drain. You can use it to store sponges, scrubbers etc beside the kitchen sink.

Self-Draining Counters

Kitchen counters are typically flat. If water spill on them, it just sit there until someone wipes it up. They should have a slight slope so they tend to drain into the sink. Further there should be no lip around the sink to block that flow, perhaps assisted by a sponge wiping.

Decent Dish Pan

Rubber Maid dish pan (aka dish tub, aka sink liner) have flat bottoms. This blocks the drain. They should have feet on the bottom to raise them us so they don’t block the drain. Rubber Maid sink tubs come only in white and cream. This mean they show every little stain. They could come in a variety of colours including very dark ones. In the meantime I added some feet from Canadian Tire (the local hardware store) for mine. The feet have adhesive which is amazingly strong. A also applied feet to the containers that sit on the counter to raise them a bit out of any spilled water.

Smart Toilet

The tank is mounted flush against the ceiling to get maximum head pressure.
The bowl is shaped to swirl the water in such a way as to scrub the sides of the bowl when it flushes.
There is a tiny camera and crude vision computer that monitors the contents of the bowl. It avoids using any more water than necessary to get the job done.
A small motor lifts and lowers the seat intelligently, depending on how the person approaches the toilet.
You might tackle the problem of how the toilet could detect when it needed cleaning, and what it could do to clean itself.
It is fail safe in case you lose AC power.
You might get some ideas from the public toilets used in airports.
