Scientific and technological creative works and boutiques 5, innovative scientific and technological

The works of scientific and technological invention are as follows:

The small scientific and technological productions invented by primary school students include vehicle overload alarms, multi-functional windproof drying racks, automatic water feeders, ball pickers, sound and light baby urine reporters, and simple mouse traps. Although it looks a little simple, it contains the wisdom of the children, and Butong feels that it is quite practical and practical.

Automatic water feeder.

First, the working principle uses atmospheric pressure to automatically control the water output, so as to achieve the purpose of automatic water supply.

Second, the production method.

1. Material preparation: one 1000ml cola bottle, one mineral water bottle, 40 cm diameter plastic tube.

2. Assembly steps:

1) Drill 2 cm diameter holes in the cap of the mineral water bottle.

2) Cut the plastic pipe into a length of 30 cm for positioning the water pipe, and 10 cm for the water supply pipe, respectively, insert one of the long ones into the bottom of the bottle, and the other one to the mouth of the bottle.

3) Take the bottom 10 cm of the cola bottle and cut it out as a water basin, and drill a hole with a diameter of centimeters on the top and bottom of the water basin.

4) Insert the water supply pipe into the lower hole, and position the water pipe into the lower hole.

5) Use iron wire to connect the water bottle and the basin.

3. How to use.

1. Twist the orange and open the lid of the water bottle and pour it back with water, and pour an appropriate amount of water into the basin.

2. When the water in the basin is lower than the water line, the water in the water bottle will flow out. When the water in the basin is above the water level, the water bottle stops supplying water again.

Fourth, the scope of application: to feed small animals with water.

Scientific and technological works refer to the development of products with creative thinking based on the concept of science and technology or advanced science and technology.

The characteristics of small production of science and technology are rich in science and technology, simple structure, easy to find materials, easy to process, less cost, can be completed independently, etc., especially suitable for students, can cultivate students' creative ability, thinking ability and hands-on ability. Teachers can appropriately inspire students to create high-quality small productions.

The types of small scientific and technological productions can be divided into two types: imitation type and creative type according to the different ways of thinking about small scientific and technological production.

Features of small production of technology:

1) Simple structure. Generally, you only need to make a few parts and assemble them.

2) The material is easy to find. Many materials can be found at home, such as empty cartons, toothpaste skins, styrofoam, canning cylinders, waste ballpoint pen refills, broken toys, iron wire, iron sheets, etc.

3) Easy processing. Most of the projects have low technical requirements and can be mastered by primary school students.

4) Spend less. Some programs can even cost nothing and do not add to the burden on the family.

5) Many projects can be completed in just one day or half a day, which is in line with the psychology of children and is easy to popularize.

It is very inconvenient to use ordinary protractors, first, there are many steps to measure and draw angles; The second is that it has two circles of scales inside and outside, which is easy for beginners to make mistakes; The third is that when measuring the angle of the shorter edge, it must be extended before it can be read.

In view of the above shortcomings, we have designed a new type of protractor, which is easy to use, and the angle measurement and angle painting can be done in one go.

Rivete two identical protractors at the center of the circle and rotate them flexibly, and make a gap of l centimeters long along the right end of the upper protractor (as shown in the figure). When measuring an angle, let its opening coincide with the two sides of the angle to be measured, and the scale indicated by the notch is the degree of this angle; When drawing the corners, first align the notch with the specified scale, and then draw two rays along the opening. This protractor can also measure the angle of three-dimensional objects such as nuts.

Because this kind of protractor resembles a scissor when used, we call it a "scissor protractor".

It is a toy made of a drink bottle and a bamboo tube. When the water bottle is filled, it squirts out water and rotates to form a curtain of water. It's very pretty, can you do it with me?

1 Prepare an empty plastic bottle for drinks and a bamboo tube with a diameter of 20mm and a length of 250mm.

When making, first see two saws in the middle of the two ends of the bamboo pipe according to the figure, and then use a knife to cut off the upper half (pay attention to safety when operating with a knife!). ）。

2 Then drill a 5mm hole at both ends of the bamboo pipe in the opposite direction slightly above the bamboo joint, and then make two rubber or cork cork seals.

3 Unscrew the cap, drill a 2 mm diameter hole in the cap, thread a 500 mm long nylon rope, and wrap a bamboo skewer with a diameter of 4 5 (mm) and a length of 15 mm (Figure 2).

4. Drill a round hole with a diameter of 20mm on both sides of the lower end of the beverage bottle, and insert the bamboo pipe into the two holes according to Figure 3, and then pour paraffin (or glue) to block the interface to prevent it from leaking.

Two little ideas, quite simple. The owner of the watchtower adopts the post-scoring !!

Very creative product designs include cat dryers, hidden folding chairs, pet pools, tape cutters, abs bread.

1. Cat dryer

Bathing a pet is a troublesome thing, blowing dry thick hair for pets is a headache, the designer designed this machine that can dry pet cats, I believe it will be loved by shovelers.

2. Hidden folding chairs

Chairs often take up a lot of space, and it seems like a good idea to hide them on the ground when not in use.

3. Pet pool

Stray cats, dogs and wild animals can be seen everywhere, they may not have drunk a sip of water for a long time, this pool is designed to wash hands with a faucet above, and a basin below to collect the water for washing hands, so that stray animals also have water to drink. Number of rocks.

4. Tape cutter

Tape is an indispensable tool in our lives, but cutting tape is a troublesome thing, many times we tear the tape, but can not find the cutting tool, can only use their own teeth to bite it off, bite off but find that the hand is stuck with the tape, people are very mad, this creative machine cutting tape may be able to solve this problem.

5. Abdominal muscle bread

In order to attract customers to buy, the bakery has designed a lot of creative breads, such as animal-shaped bread, landscape bread, etc., and this bread modeled after human abs seems to be very popular.

Jon's industry design is still good. It can be said that it is a better industrial design company in Taizhou. **The service has nothing to say.

The very creative product design is as follows:

1. The table lamp can be changed at will according to the need, and the shape looks like a cute stickman.

2. The folding reclining chair that is perfectly combined with the floor by the pool is the floor when not in use.

3. Stacked together is a decorative bowl, I believe no one will refuse such a creative kitchenware.

4. The solitaire with a simple interface makes people feel individual.

8. The small coffee table in the shape of a hippo, the glass on it makes the hippopotamus look like it is soaked in water, which is a perfect combination of nature and creativity.

Product design

Product design is a series of technical work from the formulation of new product design instructions to the design of product samples. Its work content is to formulate the product design task book and implement the project requirements in the design task book, including the performance, structure, specification, type, material, internal and external quality, life, reliability, use conditions, technical and economic indicators that should be achieved, etc.
