Was es macht
OnePot enables easy cooking at high pressure. Pressure cookers can cook at temperatures over 100°C, saving energy, time and water. Compared to other devices, this concept enables simple, transparent and safe operation.
Deine Inspiration
The problem that I have identified is the low level of acceptance and use of the pressure cooker principle in society, especially among young people. Pressure cookers offer immense advantages over normal cooking pots. The high internal pressure means that higher boiling temperatures of up to 120°C can be achieved. This reduces cooking time, energy consumption, water consumption and retains more vitamins. However, many people are afraid of pressure cookers because of the complicated operation, the "hissing blackbox" and the (supposedly) low level of safety. I have tried to solve this problem.
So funktioniert es
Pressure cookers generate high pressure inside the pot, which increases the boiling temperature. This means that water does not boil at 100°C but at 120°C. Cooking is faster. This saves energy, time and water. Important elements when it comes to climate protection. The OnePot concept stands out due to its simple, transparent and safe operation. A safety mechanism and the optimal use of plastic and metal reduce the risk of burns. touch plastic, avoid metal. For the first time, a viewing window has been integrated into a pressure cooker. This allows the user to see the food being cooked and better understand the cooking process. Special glass withstands the pressure. A kind of magnetic windshield wiper, which is linked to the digital control element, prevents condensation. The highlight is a digital control element, which is controlled by a rotary knob. By entering the food to be cooked, the time, pressure and temperature are automatically set. User-friendly.
Designprozess
This project was my master's thesis at the Magdeburg-Stendal University of Applied Sciences in cooperation with the company WMF in Geislingen near Stuttgart. The design process began with a lot of research on the subject of pressure cookers. I wanted to understand why so few young people use pressure cookers. Through various surveys, I learned about various points of criticism and decided to focus on them for my master's thesis. The focus of my work was therefore user-friendliness and safety. I then developed initial sketches and drafts. The drafts were quickly expanded into three dimensions. My professor from Magdeburg near Berlin was able to give me design feedback. I was able to ask the engineers at WMF in Stuttgart about how pressure cookers work. To ensure good user-friendliness, I really wanted to open the "black box". The user should see what happens inside a pressure cooker. This is how the idea of a viewing window came about, which brought with it a lot of problems that I spent a long time solving. I developed various mockups and a prototype. Using 3D printing, I was able to adjust ergonomic details. After 6 months I finished my work.
Warum es anders ist
The user researches on the Internet at what time and pressure he needs to cook potatoes, for example. The user fills the pressure cooker with water and potatoes and switches on the stove. The user then has to stop the time on an external device, such as a smartphone. The user cannot see the contents of the pot. It is a black box. After the time on the smartphone, the pressure is released and the potatoes may be ready. A complicated process that puts off many users. My concept solves many of these problems. A digital control element allows the food to be set. Potatoes again. The user confirms this and a timer starts automatically. The pressure and temperature inside the pot are set automatically. The user does not have to do anything else. During the cooking process, the user can look into the pressure cooker through a viewing window. The design is coordinated so that the pot takes up less space in the kitchen cupboard and is more ergonomic and easier to carry.
Pläne für die Zukunft
After my master's thesis, I realized how important pressure cookers are, especially in poorer regions, where energy and water are limited. My current concept aims to be as user-friendly as possible. It is technically feasible, but very expensive. Even too expensive for my cooperation partner at the time, WMF. In the future, I personally plan to pursue this idea without a cooperation partner and revise various aspects of the concept and adapt them for a low-budget target group. One idea was to replace the digital, magnetic anti-condensation wiper with a mechanical version.
