New Shopping trolley everyday-carry form-factor
Context
As a Student Product Designer, I tried to solve the everyday carry of grocery goods issue. To do so I did a deep study analysis of the market products & and ergonomy solutions, user-tested multiple form factor prototypes and gathered design & usability feedback, until I came up with an end-product that made sense and solved most detected issues.
What is it?
It is a multi-function shopping trolley & bag, that adapts to the user's needs by changing its geometry to best fit the circumstances:
-
It mounts on a bike mount for easy travel
-
It can be carried like a shoulder bag for everyday usage
-
It unfolds to get more significant storage space out of it
-
It converts into a rolling trolley mode to carry heavy goods easily
How does it work?
This product is mainly made out of a plastic body. It used 2 retractable side panels linked with fabric boxes to the main body to provide retractable storage space. It has embedded wheels & telescopic handle.

Process
Problem
Most active citizens living in city center of towns and cities face the problem of carrying grocery store without a car to bring it back home. Most of this population uses their work-bag, or some extra bags that can easily get heavy on the way home.
Hypothesis
Re-modernizing the shopping trolley could be the solution to this every-day pain, by making it more modern, adapted to new usages, and easy to carry even when not used.
Solution & Validation
I analysed the shopping trolley market and realized the form factor hadn't changed in the past 70 years.
​
I ran a research survey study with 20 participants to understand how they individually perceive the shopping trolley, and how they solve the grocery goods carrying issue.
​
I started ideating around the detected user needs, which included the ability to transport grocery goods on new transportation methods, including the bicycle.
I built 3 concept cardboard mockups to user test with 7 persons and gather usability feedback on multiple form factors & sizes.
​
With this feedback, I 3D modelled & engineered a fully fletched-out solution.
​
This concept received positive feedback but required a major investment to be properly tested, which I didn't do.
However, it would require some more tests:
-
Usability test to validate the product's end-usability
-
Concept validation test to validate user interest in the product & its pricing strategy.
