Background
The foot button has the same function as the button, is mostly circular, can be operated by tiptoes or soles and is often operated in a standing posture. Suitable for both hands full or for distribution of upper and lower limb loads. Due to the poor sensitivity of the foot, it is often used for non-critical or infrequent operations. For example, foot-operated buttons are commonly used for controlling machine tools and medical equipment, and some household floor switches also take the form of foot-operated buttons.
For the foot pedal, the two most important force parameters are the maximum force parameter and the appropriate actuation force range. The maximum force refers to the maximum force which can be applied by the legs of the human body in a static state, the maximum force parameter is an important parameter which needs to be referred to for designing the foot-operated control device, and the operating force of the foot-operated control device cannot exceed the maximum force which can be applied by the human body. The proper operating force is measured by the endurance time of the tested object under a certain force, and the selection of the proper operating force is directly related to whether the user can safely and comfortably complete the operation. In the prior art, designers usually set the stroke and the operating force of the foot button according to experience, however, the parameters set according to the experience may not be suitable for the requirements of most users.
