#2758: Vectairing

I have a very limited understanding of rules in general. Formula 1 rules are a particular mystery, and yet it’s often by bending these that teams win. Sometimes a tiny change can have a large effect.

Today’s invention is a subtle change which might give someone a worthwhile advantage (and which may only be allowed in certain forms of motor racing).

As the green car travels around the grey curve, its air intake (blue, towards the back of the car) is at a slight angle to the direction of motion (red).

Having an intake which can swivel automatically, so as to continually align with the direction of motion would give a very small, but perhaps important, increase in airflow and thus performance.

#2757: TyRetread

The McLaren formula one team apparently takes a 3D printer with them to the trackside during races.

This is supposed to allow the creation of replacement parts during the race (although I’m not sure about how the F1 rules people regard that).

Today’s invention is inspired by that idea, but for a much more prosaic purpose.

In order to extend the life of everyone’s car tyres, imagine a small 3D printer that fits inside a car’s wheel arch and delivers a very fine layer of rubber onto the surface of a tyre, in the correct tread pattern.

A car, parked on say a Quickjack, might have four of these operating, perhaps every night, scrubbing and rotating each wheel whilst providing a nice, new, vulcanised rubber surface by morning.

#2755: Fillipuzzle

If I want a picture than I will paint one. That’s why I don’t understand the attraction of jigsaw puzzles. That and the fact that there is always a piece missing.

Today’s invention offers a way to deal with the latter problem.

When you have assembled your jigsaw and found that a piece is awol, simply use your phone to photograph both the gap and the overall image.

When these are sent to an image database, the overall scene is identified and a new piece made with the correct image on it (by eg printing onto a laser cut piece of cardboard).

If the overall scene can’t be identified, then the new piece is made by interpolating the colour and texture around the edges of the missing piece, in a way that is similar to how the blind spot fills in perceptual content.

This would work very well for maybe 90% of jigsaw pieces, since they are designed to have hard-to-recognise, ie featureless, textural regions.

If you wanted a solution the same day, without having to wait for postal delivery of your piece, it might even be 3D printed in your home.

#2754: TideRider

It takes the moon about 27 days to orbit the earth.

Today’s invention is a ship which rides on the tide which results from this movement and can thus circumnavigate the world using zero fuel (or nearly so).

It would have to travel roughly along a single route, but that may not be as important as the fuel saving…especially if the ship was very large.

#2752: MouseRehouse

Many people don’t like mice in their homes, but don’t want to kill them.

They therefore use humane traps and then have to move a live mouse to some distant location.

Today’s invention is a discreet way to trap a mouse and then covertly release it somewhere else during a walk away from home.

It consists of a humane trap which can be attached to the end of a walking stick.

You attach the trap, with mouse in, to the stick, go for a walk and then press a catch in the handle to allow the mouse a new lease on life.

(An alternative would be to attach the trap to a remotely controlled vehicle which would be preprogrammed to scuttle off to a distant location and then open the door before returning home).

#2751: BellShells

Today’s invention is a set of physically large kettlebell-shaped shells made of stretchy foam rubber.

These are designed to have a slit in the top so that even a large kettlebell can be placed inside. The shells have no external markings.

The shells are all the same size and may accommodate conventional kettle bells of any weight, so that people aren’t
a) tempted to show off with weights that are too heavy or
b) embarrassed by using very small weights when beginning exercise.

#2750: Officerifle

I’m given to understand that officers in modern warfare often have to carry a rifle they’ll never use, in order not to be seen as a priority target by eg enemy snipers.

Today’s invention is therefore an imitation rifle which is super lightweight and which can be carried, on a strap, by officers just to help them avoid being singled out.

This could be hollow, in order to hold securely any lightweight, loose items that an officer needed to carry.

It would be marked so that anyone close by could see it was fake and not attempt to use it for self defence.

#2749: ScreenSucker

Somebody invented a new way to harrass thoughtless motorists…a suction device that attaches to the windscreen of a badly parked car in order to make it undriveable.

So, in order to further the fight against officialdom, I just invented the obvious countermeasure.

It’s a (small) suction clamp that I leave attached to my screen, which prevents their barnacle clamp from ever being attached. A sign would say ‘Do not attempt to remove’. The lever arm would be lockable, when the sucker was in place.

(I might couple that to a dash camera so that any attempts to remove my sucker would be recorded for use in court, if my vehicle got damaged).
