Digital Component in Craft Trades [Part II]

In the previous part of this series of articles, we presented the analysis phase and initial digital concept approaches. With the concept approach of a sensor-based drilling machine, we are now entering the ideation phase. We ask ourselves how holes can be drilled safely and com­fortably with consis­tent quality using just a few tools. This helps us to sharpen our vision.

The sensor technology could support or take over several steps of the drilling process:

• The bit is detected by an optical sensor when inserted

• Material scan before drilling – radar and capacitive sensor tech­nology

• Automatic speed and mode adjustment depending on the type of drill bit

• Depth limit and drilling aid adjust­ment

• Position sensor helps as an alignment assis­tant for precise 90° drilling

• Visual and haptic feedback in case of danger or changes

The number of useful features seems enormous. The user can place a drill against the wall, which auto­matically scans the sub­strate and lights up red if there are any elec­trical cables, or suggests the optimal drilling depth for the sub­strate in other places. The smart drill can think for itself and provide safety without the need for additional devices.

In the ideation phase, we work out how the special features of the sensor tech­nology can be high­lighted functionally and aesthe­tically in the design of the machine. We also develop ideas on how to distin­guish between a support mode and manual ope­ration.

We initially sketched two different sensor conc­epts: a modular sensor ring and a digital pencil. The con­cepts differ in the shape and hand­ling of the sensors and illustrate possible diffe­rences in the design of the machine. They served as a basis for deciding on the more detailed version—a smart drill with a sensor ring at its heart.

Based on the decision to use a drill concept with a sensor ring, our team can develop a creative product design. Storyboards are used to refine design features and ease of use. Sketches are used for visua­lization. AI-generated images can also be helpful at this stage of the process. This approach allows fea­tures to be deve­loped and a user inter­face to be designed that enables inter­action with the machine. Color schemes, comple­mentary gadgets, and inter­actions are all part of the ideation process.

In a third article, we show how we make the tool concept tangible with the help of story­telling and provide an outlook on the steps that can be taken to further develop the design concept.
