First of all, this is a graduation work, so the design and rendering are not very mature. I hope you can give me your advice. Most of the time, the minute hand and the second hand keep turning will affect my concentration, so I hope to design a desktop clock that allows me to focus on what I am doing now. So the three-sided clock was designed with the pyramid as the prototype to extract the shape. The three pointer systems are disassembled into three different planes for independent display. When using, I only need to turn to the required surface and face myself, so I can't see the pointer influence of other surfaces, thus avoiding the anxiety caused by pointer rotation. As for the design of the dial, the traditional dial design (as shown in the figure) was originally used, but later I felt that it was somewhat out of touch with the whole design, leaving only the red indications of 11 o'clock and 6 o'clock. 11 and 6 correspond to the east longitude of my hometown Tiananmen Square in Beijing at 116 degrees. This may be a little hometown sentiment of overseas students. I hope I can learn from foreigners to control foreigners. I can Do not forget your initiative mind. The hour hand dial I changed the traditional clock gear structure to seek the hour hand to turn only once an hour. The 60-degree gear transmission angle from the power system to the three-sided display system is the most troublesome part for me. Since no one has designed the three-dimensional clock mechanical structure, the difficulty of the whole work lies in the gear system calculation and space utilization of the three-dimensional mechanical structure. I hope everyone likes this work.
