To use the subject attachment method, you must first determine the purpose of the subject attachment. You can comprehensively analyze the shortcomings of the subject through the shortcomings enumeration method, then use the hope point enumeration method to list various hopes, and then determine a certain hope as an additional purpose. Secondly, determine the additional items based on their additional purpose. The creativity of the subject attachment method largely depends on whether the choice of attachments enables the subject to generate new functions and values ??to increase its practicality.
For example: a fan plus a timer, a refrigerator plus a temperature display, a remote control attached to a color TV, a pencil with an eraser tip, food containing trace elements, etc., and a white bar plus a traffic light was patented.
Pang Yingchao from Changshu Middle School in Jiangsu Province invented a traffic light that can be recognized by color blindness. It adds some white regular-shaped graphics to the current pure red and green lights. For example, add a horizontal white bar in the middle of a red circle, and add a vertical white bar in the middle of a green circle to allow color blindness to identify. "Our current traffic lights are all red and green, and those with color blindness cannot distinguish these two colors, which brings great inconvenience to their lives." To prove how big this inconvenience is, Pang Yingchao Cited a data: color blindness accounts for 5.6% of the world's population. "Once, I saw a traffic policeman arresting a person who ran a red light. It turned out that he was color blind and couldn't distinguish between traffic lights, so I came up with the idea of ??making this traffic light."
Example: The cup is made of Used to hold water and drink water. So can cups be revolutionized? An engineer invented the magnetized cup using the main body addition method. He added a magnet to the bottom of the cup and a magnet to the cup lid. After the water in the cup was magnetized, its solubility and dissolved oxygen content were increased. When people drink magnetized water, it is beneficial to the dissolution and discharge of circulatory system obstacles in the body, promotes human metabolism, and thus has health care functions. After the inventor of the magnetized cup applied for a patent, he used a loan of 10,000 yuan and a "factory building" of 10 square meters to set up the Harbin Magnetizer Factory. The factory developed rapidly and finally became a nationally famous enterprise.
