OATS VENDING MACHINE

REDESIGN OF OATS VENDING MACHINE

OVERVIEW -

To study the Godrej prima oats vending machine and then to redesign the front fascia of the machine. The idea is to bring newness, intuitiveness, via clean and safe design. The design process involves studying human-machine interaction, product study, observation, interviews, ideations, prototyping, experimentation and application of required outcomes at the end. The project took four months to complete. 

Human - Machine Interaction / Empathy

Users are observed while interacting with machine. The observations lead to understand their behaviour, points of contact and their problems related to machine. Various activities were noted down to enhance the user's experience with the machine.

Product Study

The existing oats vending machine was opened. Various parts inside fascia were examined and recorded. The activity helps to understand the various  components that need to be take care of while redesigning the fascia.

Interviews / Analysis / Brainstorming

Users were observed and interviewed during the trials of existing machine. It helps us to get better understanding of their behaviour and thoughts related to the existing machine. After analysing their responses/feedbacks, the idea/architecture of new machine was brainstormed.

Brainstorming Structure / Architecture 

Experiments / Testing 

Number of experiments were done on the machine to eliminate the major problem of spillage. The spillage was caused mainly because of the placement of cup or position of cup with respect to the funnel. At the end, the experiments lead to the new design of funnel. Followed by the testing, the design of cup tray was finalised too.

Result : Maximum allowable dislocation of cup from the centre is 10 mm.

Prototyping / 3D printed Models 

Prototype was built followed by small 3D printed models. The prototype was then used to observe people's interaction with the machine. Keeping it simple, a user has to keep the cup and hit the oats icon on the screen to get the oats.
