The following is an example of passing a club patent.
Fig. 1 is a schematic view of a golf club head, and fig. 2 is a sectional view of fig. 1 along line 2-2. The improvement of this technical scheme is to increase the main groove 2 1 and the undercut groove 22 extending back and forth, so that the parts 24 and 25 protrude backward, thus improving the torsion resistance when hitting the ball.
Using the 40 principles of invention in TRIZ theory, we can dig out more patent application schemes. For example, we try to get a new scheme by using the principle of invention No.2 (extraction principle). The principle of extraction is to extract parts or attributes that can have negative effects from objects, or only extract necessary parts or attributes from objects. In this scheme, it is necessary to simplify the structure of the club and ensure the torsion resistance of the club when hitting the ball. The grooves 2 1 and 22 of the ball head can be removed by the extraction principle, and the structures of the back convex part 24 and the rest 25 can be improved, thus obtaining the modified technical scheme, as shown in the following figure.
For another example, the shaft of each club has an optimal impact point, which can collide with the ball to produce the most "sweet" feeling, which is also called "sweet zone" in golf terminology. The "sweet zone" is mostly located at 1/3 below the club head, and the area varies from club to club. Many players prefer clubs with big "sweet zones", so how to increase the "sweet zones"? From the initial core improvement, we can try to get a solution by principle No.4 (adding asymmetry principle): add flange 50 to the structure of the club to get a new and improved patented technical solution, as shown in the following figure.
For example, when the club collides with the golf ball, it will produce a loud sound. How to reduce this sound? After skillfully applying 40 invention principles, we will think of the invention principle of 17 of "replacing single-layer structure with multi-layer structure", that is, the principle of spatial size change, and improve it: the original damping plate 450 is configured as a multi-layer structure, including adhesive layer 45 1a and thin layers 45 1b and 45/kloc-0 on both sides.
In addition to the above examples, there are many improvement directions waiting for us to explore, such as using the principle of 3 1 bar to reduce the weight of clubs, which can be used as peripheral improvement patents to enrich core patent applications.
