AI Technical Summary

Technical Problem

Existing power bank charging cables are silent or lack rhythm when stretched, are bulky, and the use of metal materials for the central column increases costs, making it difficult to achieve longer cable storage within the same volume.

Method used

A travel charging module is designed by using a one-piece injection-molded central column and a high-elasticity spring, combined with a winding turntable and a start/stop lever. The high-elasticity spring reduces the volume of the winding turntable, enabling the data cable to be wound. A hammer and a toothed ring are set on the winding turntable to produce a clicking sound, improving the user experience.

Benefits of technology

It achieves cost reduction while shrinking the size of the central column, and can wrap longer data cables to improve the user experience, producing a rhythmic sound through the hammer and toothed ring.
