Saturated market

Different settings aren't always understood by the avergage user.

The market for cordless screwdrivers is hightly saturated. To stand out from the market, an innovation must be created.

Development of a compact cordless screwdriver along the design language of the brand "Gardena" and targets users who value a functional and efficient tool in the garden.

Development of a compact cordless screwdriver along the design language of the brand „Gardena“

We aimed to achieve a professional appearance with each lamp we crafted, striving to surpass the typical student-made aesthetic using our existing skillset.

As a group, we leveraged skills in woodworking, metalworking, powder coating, and various other processes, allowing us to prioritize quality and cost-effectiveness by focusing on our strengths.

01
Concept

Basic equipment with a special focus on a housing shell that is as closed as possible to prevent foreign bodies and dust from entering the interior.

02
Concept

This concept aims in particular at simplifying operation. The otherwise separate functions of gear shifting and torque adjustment are combined into one operating element.

Design Development

Ergonomic study

With the help of grip clay models, a comfortable grip shape was developed. The prototypes were tested and evaluated with hands of different sizes.

Prototyping

First Premodell

Prior to CAD design, a preliminary model was made from lightweight foam. The knowledge gained from this was taken into account in the CAD design. Using pre-models of the initial CAD data, the proportions were checked and adjusted.

Realistic final model

In model construction, all the different materials and colors had to be produced separately. Mainly, the model was produced using the resin 3D printing process. Only the two rubber halves were produced using the CNC milling process.

Technical Feature

The special feature of this cordless screwdriver is the technical concept of combining the torque adjustment and the gear shift function.

Illumination of the work area

To ensure a well-lit environment at every work station, the cordless screwdriver is equipped with a light below the drill chuck.

Components and technical data

The cordless screwdriver comes with a 12 volt rechargeable and replaceable battery.

The market for cordless screwdrivers is sufficiently saturated. To stand out from the market, an innovation must be created.

Ideally, the cordless screwdriver should always be within reach between jobs to ensure the most efficient work possible.

Development of a compact cordless screwdriver along the design language of the brand „Gardena“ and targets users who value a functional and efficient tool in the garden.

In order to gain a deeper understanding of the technical structure of a cordless screwdriver, a device was unscrewed. All parts were exactly reconstructed in CAD. The insights gained in this way, together with the findings from the market analysis, were recorded in the form of potential fields and finally in the form of concepts. After consolidation, the design was developed.
