Abstract:
1. A designing method of a wiper strip, the wiper strip including a contacting portion adapted to engage a wiping surface through a liquid film, the designing method comprising: selecting a maximum thickness of the liquid film (h obtaining a maximum pressure gradient value in the pressing pressure profile based on the following equation: setting design factors of the wiper strip based on the maximum pressure gradient value to achieve the maximum pressure gradient value in the pressing pressure profile at the contacting portion of the wiper strip at the time of wiping the wiping surface with the wiper strip, the setting of design factors including at least one of selecting and modifying at least one of a material of the wiper strip, a shape of the contacting portion of the wiper strip, and a size of the contacting portion of the wiper strip; and forming the wiper strip with the set design factors.
