Product and interaction design

Prototyping

Challenge

This project was about learning to design the inside of a product to better understand the work of an engineer and to be able to apply that thinking to our designs.

At the start we got an existing IR-thermometer. The task was to disassemble it, redesign (both the inside and outside) of it and then place the components into a 3D-printed shell of the new design. 

Concept

The final outcome of the project was a new, branded design of a working IR-thermometer prototype.

I chose to brand it for Stelton and focused on simplicity, details and to create a functional design.

Change of battery

The battery can be changed by clicking on the black buttons as the same time as pulling down the lower matte part. That makes the battery visible and possible to be changed.

Repair a component

In case a component brokens or needs to be updated, the customer or technician can easily drag out the whole inner construction from the shell, by only unscrewing one screw. This makes all components released, which enables change of components.

All parts used

Manufacturing

While designing the IR-thermometer I have been thinking of the manufacturing process of it. I have added drafting angles, snap hooks and lips. The main body of the IR-thermometer would be molded with three movable cores and the inner construction with one movable core.

Redesigning an IR-thermometer within 19 hours

Tracking working time

Everyone in the class got a time sheet of our teacher where we had to write down the amount of working hours spent on each activity through the ideation.

My goal was to manage to finalize my design within the proposed 19 hours. To do that I hade to be efficient, take fast decisions and stop working when time is out.

I choose to work with the brand Stelton who does a lot of luxury kitchen products. The form language of Stelton is following the saying “less is more” and the products should have a design which makes the consumer leaving it in the front where it’s seen. My focus was on simplicity combined with iconic details and luxury material and finish.

6. Prototyping (25,5h)

 

Ideation process

I started out with sketching many thumbnail sketches to explore a lot of different shapes in an effective way. Then I marked out my favorites that I thought would fit best to the chosen brand, Stelton.

After the thumbnail sketch session I did some 1:1 scale sketches and perspective sketches of some of my ideas, before starting to explore the shapes in foam.

building a working prototype

 
We got an IR-thermometer each which we had to analyze and disassemble.

An overview of my work

From an existing product, through mock-ups and sketches to a working prototype.

The messy 1:1 sketches to the right on the picture were the underlays to my CAD and modeling work - a lot to consider.

Final concept

 
The usage for this IR-thermometer could be when cooking or baking.

Color material finish

As all other Stelton products, the IR-thermometer comes in different color variations. I chose to show three variations of colors that I found trendy, Scandinavian and that fits to the brand. I made the top (screen) part and the battery buttons black, inspired by the classic Stelton thermos. The finish of the main part of the product is glossy and the lower (battery cap) part and trigger button are made in a matte finish. The trigger is in another finish than the main part to make it easy to feel when using the product. I wanted the lower part to be divided from the main body to convey the function that it can be removed.

Learning outcome:

  • This was my first time to design the inside of a product which I learned a lot from. For example about drafting angles, ribs, assembling and disassembling components, screw holes and screw towers.

  • Manufacturing methods

  • Improved my Solid works skills

  • Interaction design - soldering all components together

  • Assembling parts and components and get it to work
