Meet “Lock & Roll”. It is the world’s first smart locker that revolutionizes the timeworn retail experience.
While interviewing store managers and customers alike, we discovered a discrepancy between the customer’s need to touch and try a product before buying and the convenience of home delivery that online shopping provides, and smaller stores in particular can’t match.

Our idea aims to bridge that gap. By making it possible to deliver anything you put in the locker to your doorstep, you do not need to carry your heavy shopping bags around in the city or your big suitcase home when travelling.

All you need is a smartphone and our App and an account which holds the information about your address as well as your bank account for a fast and easy payment. The App is very easy to use as it guides you through every step of the process. Just by standing next to one of our lockers, it will use your current position to tell you how many vacant lockers are located nearby. After clicking „Open a Locker“, you are asked to choose between four possible locker sizes. Next it is possible to either select „Pick up Later“ or „Deliver it to me“. When the second option has been chosen, one of our Lock & Roll employees will deliver your belongings right to your doorstep just a few hours later.

After our video-prototype, the next steps are a field test to get more informations and data about the needs and problems our future customers will have.


Concept – Group 6

Concept, Group 06, WS1819

During our user research we discovered that many people like ordering online, because it is more convenient for them to have it delivered to their doorsteps. Still, many people also prefer going to the store to get consulting and to be able to see and touch the product before buying it.

We wanted to come up with a solution that would draw people that order online – because of convenience reasons – into retail stores, while also making it more convenient for people to buy more in one go when going to the city.

Our solution is called “Lock&Roll” and we offer lockers that are placed nearby malls, shopping centers or in the downtown. Users have the ability to lock their purchases away so they have their hands free to shop more. But most importantly, we also offer a delivery service for a small fee. Users can simply lock away all their shopping bags, can walk home with free hands, and have all their bags delivered to them when they arrive home.

User Research in Retail – Big and Small

Customer Interview in the bookstore Buch und Bohne


Our first interview was at “Zweirad Stadler”, a large bike shop that offers bikes for testing in the shop before purchasing. The interview revealed that this field needs local stores, and combining them with digital offers can present a great benefit.
The bookstore “Buch und Bohne” is in a similar position. We observed a very personal relationship with customers, which is an integral part of the “café meets bookstore” concept. Contrary to logistics, for example, personal advising of customers can only be digitalized to a certain degree.
Similarly, a small vinyl shop called “Best Records” focuses on personal advice and the owner does not deem digitizing anything beyond his basic web presence relevant.

In contrast, “Sportscheck” and “Sport Förg” have long digitized all processes concerning e.g. logistics, warehouse management, cash registers and customer acquisition – every customer has his own unique account, collecting relevant data. All staff has access to these accounts, enabling ideal advising of the customer. Sport Förg also offers workshops, discount campaigns, and a ski simulator to attract customers.
