Automated tool bit selection by scanning the head of a screw or bolt

Problem 1. Traditionally, the user of a tool has to manually select the appropriate tool bit for the head that they are trying to turn. Where the user has a requirement to turn multiple heads in succession, where each head differs from the other (eg. 5mm hex bolt vs 5mm torx), the user must swap the tool bit prior to the turning of each individual head. This process of swapping can be slow and cumbersome wasting the time of the user. Problem 2. If the head is difficult to see due to it being in an awkward place, it may not be an option for the user to identify the correct tool bit prior to usage potentially resulting in a damaged head. Problem 3. An inexperienced user may accidentally select the incorrect tool bit eg. 4mm hex vs 5mm hex and cause damage to the head before realising that they had selected the incorrect tool bit. Problem 4. Visually impaired users may be unable to accurately determine the appropriate tool bit by touch alone.

    This invention solves these problem by putting the onus of the tool bit selection on the tool itself meaning that as the user offers it up to each head, the tool automatically selects and augments the tool bit such that it is ready for use with no delay or user intervention.


A camera

A computer running image pattern matching software

A tool with features that allow the selection of tool bits such as the one mentioned in "US 2014/0329654 A1"

Arrangement The proximity sensor and camera are housed on the front of the the tool such that they are in alignment with the axis of the tool bits. As the user of the tool offers it...
