RU32404U1 - Mechanical Volumetric Puzzle - Google Patents

Description

The proposed utility model relates to the field of educational games, in particular, mechanical volumetric puzzles.

Currently, despite the wide development of the field of electronic educational games and puzzles, mechanical puzzles are still not one of the mass means of developing intelligence, inventive activity of the younger generation.

The most difficult, but also the most intelligent from the point of view of difficulty of solution are volumetric puzzles.

One of the directions of volumetric puzzles is puzzles in which the principle of determining the type and comparison of geometric shapes is widely used.

So, the puzzle / 1 / is known, in which there is a set of game bodies of different geometric shapes, placed in a collapsible hollow cube, in all six faces of which holes are cut that repeat the geometric shape of the bodies from the set.

Solving the puzzle, first by comparing, determines which of the set the geometric body must be taken in order to match the shape of the hole in

the corresponding face of the cube, and then insert the selected body through this hole.

The disadvantage of the puzzle is its low playfulness, due to the elementary level of the problem being solved.

There is a well-known puzzle / 2 /, which represents a hollow cube, the side faces of which are grated, the bottom is solid, and a hole in the form of a square is made in the upper / ceiling / face, the diagonal of which is equal to the size of the edge of the game element, made in the form of a tetrahedron, placed with the possibility of free move inside the cube.

The disadvantage of this puzzle is the only solution to the problem - to take the tetrahedron out of the cube through a single hole, which reduces the fun

puzzles.

The above puzzle is 111 and selected by the author as a prototype proposed, as closest to it in technical essence and the achieved positive effect.

The task that the author posed when developing the proposed puzzle was to increase the entertaining game of the puzzle by expanding the options for trying to solve it without significantly complicating the design of the puzzle.

This problem is solved in the construction of the puzzle, which is mainly a hollow cube with a game element in the form of a body, which is a combination of a tetrahedron and a ball with a common center and a diameter of the ball satisfying the expression:

where D is the diameter of the ball of the game element and A is the length of the edge of the tetrahedron of the game element, while at least one of the faces of the cube has a hole whose shape is a circle, a triangle or any projection of the game element, and the dimensions are not taken from the condition the passage of the game element through the selected hole.

New significant features in relation to the selected prototype are:

- the implementation of the game element in the form of a body, which is a combination of a tetrahedron and a ball with a common center and a diameter of the ball, satisfying the expression: g -D

where D is the diameter of the ball of the game element, and A is the length of the edge of the tetrahedron of the game element;

- making at least one of the faces of the cube of the hole, the shape of which is a circle, a triangle or one of the possible projections of the game element, with dimensions taken from the condition that the game element does not pass through the selected hole.

The proposed puzzle is presented in the drawing, where:

1- hollow cube;

2 - a square hole whose diagonal is equal to the size of the edge of the tetrahedron of the game element, and the side to the diameter of the ball of the game element;

3-7 holes in the faces of the cube in the form of a circle, a triangle and

projections of the game element with dimensions taken from the condition

not passing the game element through the selected

hole;

8 - game element in the form of a body, which is a

a combination of a tetrahedron and a ball with a common center and diameter of the ball,

satisfying expression: / t „A

where D is the diameter of the ball of the game element, and A is the edge size of the tetrahedron of the game element;

Work with the puzzle is as follows.

To solve the puzzle, the game element 8 must be inside the cube 1 with the possibility of free movement.

The task of the solving puzzle is to remove the game element 8 from the cube 1 through any hole in the side faces of the cube.

The visually square hole 2 in the cube is much smaller than the dimensions of the game element 8, so the solving puzzle begins to try to remove the game element 8 through holes 3 7.

But the holes are made so that, for example, the ball part of the game element 8 enters the hole 3, but the tetrahedron does not pass, the tetrahedron enters the hole 4, but the ball part of the element 8 does not pass, etc.

In connection with these circumstances, solving the puzzle becomes more entertaining, because there are more options for trying to solve.

But in fact, there is only one solution to the puzzle - through square hole 2 in the cube, because there is one position of the game element 8, when the ball and tetrahedron form a projection in the form of a square corresponding to the hole 2, and the game element 8 is removed from the cube 1.

The industrial implementation of the puzzle is not difficult, because the puzzle can be made of wood, plastic and other materials using technologies known in the art, using well-known equipment ..

 years

Currently, the author has made prototypes of the puzzle, the practice of testing which has confirmed a significant increase in the entertainingness of its solution.

A utility model is being worked on at one of the industrial development enterprises of the Moscow Region.
