Abstract


Stand Mixer design for the company Jambo in Ningbo. The stand mixer is for small scale commercial use and domestic use.

While the internal components of the stand mixer adhere to the company's specifications, the primary focus of my efforts lies in enhancing the external aesthetics of the product. The client's key directive is to elevate the uniqueness of the product's appearance.

Research


1. Brand Analysis






2. Market Analysis


The Jambo mixer, characterized by its substantial size and precision in speed levels, appeals to a niche market with a strong emphasis on quality. The relatively higher price positions it for users who prioritize performance in their culinary pursuits.

Potential users include cooking enthusiasts with big families or small-scale pastry and dessert businesses. The mixer's attributes, such as a sizable bowl and exact speed control, cater to the demands of those who seek both efficiency and excellence in their culinary endeavors.


3. Mixer Component Study


Through disassembling sample mixers and watching videos, I was able to understand how the stand mixers function.


4. User Research


I proactively reached out to several local bakeries and coffee shops, securing permission to enter their kitchens for insightful interviews. I was also able to observe the wear of paint on the frequently used machines to see which parts are frequently bumped and touched.

Mechanism---Rotating-Sliding-Swinging








Modelling and Manufacturing












Design Features


1. Environment


I used basic geometries and warm lightings to simulate a kitchen environment at dusk, which shows how the machine will look like when people return home from a whole day’s work and start prepare meals for family.


2. Shape and Form


3. Material Choice


Die casting (pressure die casting) will be used for most components.

4. Top Screen Interface


A touch screen was placed on the top casing of the machine. is on a surface slightly inclined towards users. It shows common guidelines (what speed should be used for making doughs/ cream/ milk cover, what are the ingredients and proportions of ingredients…), current rotating speed and timing. This screen is commonly used before starting to prepare food and after the mixing begins.

5. Speed Control Slide




6. Power Switch


7. Lock Handle


The handle controls the locking of the head’s position. It is connected to an oval shaft that goes through the hinge. The shaft is made of stainless steel as it undertake load, the visible part is covered with a layer of soft rubber.

8. Intuitive Design


9. Rubber Feet


In observations, when bakers take out the bowl, the machine slips on the table thus making it harder to take out the bowl. Therefore, it is necessary for the design to stay fixed.

10. Tilt Head


The machine kept the tilt head design as it is commonly known to most users. The angle of tilting is limited by the hinge, which is 30 degrees. This degree is stable, and the bowl can be taken out without having to remove the whisk.

11. Logo Placement


The logo is placed on the left side of the top casing. The font is kept the same as requested. The background is removed to provide a minimal, elegant and high-end feeling

12. Internal Assembly


There are 21 components in total in this design.
