Ergonomics and Cost Effectiveness
Accumulators with a high capacity inevitably weigh a lot. Especially in professional use, battery operated handtools quickly reach their limits. Alternatively, there are line-operated devices, although freedom of movement and comfort are thus limited.
[1] The energy source is separated from the handtool - The heavy rechargeable battery and the drive unit are carried comfortably around the waist.
[2] A torsional wave transmits the energy over the shoulder to the hand set
[3] The weight of the hand set is reduced to a minimum
The system is composed of a drive unit, carrying system and hand set.
Different hand sets can be operated by the drive unit. The more handsets that can be operated by the same drive unit, the more economical the purchase of the entire tool system gets.
Function and design study
The carrying system is developed in collaboration with Mammut Sports Group. These prototypes serve as technical evaluation and field tests.
Insight into the development
A successful partnership begins between the product development branch of the ETH Zurich and the Industrial Design section at the Zurich University of the Arts.
The rights to the new tool system are patented worldwide by the BOSCH company.
The project was awarded the top prize by the Dyson Student Award.
Below you get an insight into the project.
As a first step market research, consumer surveys and monitoring are carried out.
Ideas and solutions are collected.
The team discusses and evaluates the solutions.
As soon as the basic composition of the system is defined, the design process can start.
The drafts are assembled with CAD and critical elements are checked by a FEM-Simulation.
On the basis of the CAD data, prototypes are constructed and the fit of the component parts is tested..
The prototypes are used to validate the ergonomics of the system.
Eventually, the individual components are assembled and the electronics soldered.
The performance data is determined in laboratory tests.
