Nail Clipping Device with a Warning Module

Abstract

A nail clipping device with warning functions is disclosed, including: a nail clipper with arc-shaped cutting edges; a capacitive sensing module, located below the arc-shaped cutting edges of the nail clipper, enables measurement of the distance between the arc-shaped cutting edges of the nail clipper and the flesh below the nail; a warning module, located above the arc-shaped cutting edges of the nail clipper; and a control module, located at the lower portion of the device, and coupled to the capacitive sensing module and the warning module, capable of pre-setting a warning distance and comparing its corresponding reference voltage with variable sensing voltage, the control module amplifies and filters the output signal from the capacitive sensing module after voltage comparison, driving the warning module to emit a warning signal when the distance between the arc-shaped cutting edges of the nail clipper and the flesh below the nail is shorter than the warning distance.

Description

TECHNICAL FIELD[0001]The present invention relates to nail clippers, especially to a nail clipping device with warning functions.BACKGROUND[0002]During the human growth process, as nails often grow rather fast, there may be safety and hygiene issues associated with skins being scraped by nails and dirt hidden underneath the nails, making it essential to trim nails frequently. However, it is very difficult to trim children or babies' nails with common nail clippers, as they would often wiggle or resist, making it hard to align the nail clipper with the nails. Misuse of nail clippers when trimming a baby's short and delicate nails may result in accidents involving the flesh being cut, and this unhappy experience may lead the baby to further resist nail trimming thereafter, causing more difficulties and inconveniences for the parents in the future.[0003]The existing capacitive sensing technology has been developed to become a rather matured technology, which may be applied to thousands...

Benefits of technology

[0007]More specifically, the present invention provides a nail clipping device with warning functions, the device comprises: a nail clipper with arc-shaped cutting edges; a capacitive sensing module, located below the arc-shaped cutting edges of the nail clipper, enables measurement of the distance between the arc-shaped cutting edges of the nail clipper and the flesh below the nail; a warning module, coupled to the capacitive sensing module and located above the arc-shaped cutting edges of the nail clipper for providing warnings; and a control module, located at the lower portion of the nail clipping device, and coupled to the capacitive sensing module and the warning module. The control module is capable of pre-setting a warning distance and comparing its corresponding reference voltage with variable sensing voltage. The control module amplifies and filters the output signal from the capacitive sensing module after voltage comparison, driving the LED indicators on the warning module to go from green to red, or causing the speaker to produce warning noises as a warning signal when the distance between the arc-shaped cutting edges of the nail clipper and the flesh below the nail is shorter than the warning distance. This serves to prevent clipping accidents from happening, and when the distance between the arc-shaped cutting edges of the nail clipper and the flesh below the nail is greater than the warning distance, the control module turns the LED indicators on the warning module back to green.

Problems solved by technology

During the human growth process, as nails often grow rather fast, there may be safety and hygiene issues associated with skins being scraped by nails and dirt hidden underneath the nails, making it essential to trim nails frequently.

However, it is very difficult to trim children or babies' nails with common nail clippers, as they would often wiggle or resist, making it hard to align the nail clipper with the nails.

Misuse of nail clippers when trimming a baby's short and delicate nails may result in accidents involving the flesh being cut, and this unhappy experience may lead the baby to further resist nail trimming thereafter, causing more difficulties and inconveniences for the parents in the future.
