While maintaining the original weight, the ratchet's engagement surface area (relative to a system with the "same tooth count") has been increased by approximately 20%. This significantly improves the load-bearing capacity of the planetary gear system, resulting in more stable and reliable power transmission. Furthermore, the larger engagement area provides a higher degree of redundancy for the ratchet's engagement state, thereby significantly enhancing operational stability. This guiding design enables the pawl to engage with the gear more smoothly and precisely, resulting in a faster engagement process, significantly reduced backlash, and a more direct power response.
