Construction truck cabin

User studies for designing a cabin for a construction truck

Problem

The majority of trucks on the market are targeted towards long transportation of gods. But some trucks are used for day to day construction jobs, such as gravel trucks, cranes, etc. The usage of these trucks is quite different from the long transportation drives.

The focus in this school project is to tackle how a truck cabin could be constructed in order to suite these trucks used in the construction industry. For consumer insight and usage feedback we worked close with the end user in this project. By using mock-ups we could understand their needs and verify our ideas. Scania lent us an entire truck cabin that we had in school and could rebuild and do tests on.

This project was made in collaboration with Calle Uggla.


User observation

The first thing we did was to observe the user by following a driver around for a full day, observing the behaviour and listening to his/her story.



 Needs Analysis

  • When dirty and wet, there is a need to be able to dry damp equipment like gloves and straps
  • There is no natural place for the tools and clothes
  • The light is insufficient for several tasks
  • There is a demand for the possibility to personalize the cabin

Outcome: Storage and Struckture


 Phase 1 – Ideation sketches


Phase 1 – mocups & testing with user


 Evaluate phase 1

After the first user test we came to the following conclusions:

  • The rail was greatly appreciated because of its flexibility.
  • We discussed the topic of dividing the cabin into two different zones, one where they could store all their damp and dirty items and one who could be an “office” work for recites and driving orders.
  • The topic of the absence of light in the cabin came up again. Many of the drivers had to install lights of their own in order to get the sufficient light.
  • It appeared that there was no actual need for a passenger seat since they very seldom have a passenger. This was often used as a storage space.

Outcome: Storage, structure and lighting


 Phase 2 – Testing the concept & building the final mock-up

For the last user test, we tried out the final concept with different proportions of the two areas and the best suitable materials.

  1. Testing different height of the back panel
  2. The size of the rough backpanel and what sort of things the driver would want to place there
  3. A place for the very important coffee cup
  4. The final mock-up

Final result – Two zones, Clean/Dirty

The cabin is now divided into two areas. Where the passengers stool used to be is now a bench covered in a rubber carpet. The area under the bench works as a drying cabinet that can be closed for better drying.

As for the “office” area there is a wooden plate that is used as a table to get a desk feeling. The rail is placed on two heights of the wall. They work as a holding structure for the different add-ons you can use to personalize the work area, a hook for your jacket at that very special placement or why not a clip for the COM radio or your mobile phone.

The lightning is divided in three levels: Driving, directional and work:

  • Driving is a soft coloured light behind the upper rail to make a pleasant illumination of the cabin when driving
  • Directional is made of a flexible arm with a light in the end to target special areas in the cabin
  • Work light is several lights in the roof that brightly lights the whole cabin
