This concept is best because of the angle suit to the walking pattern, thus, people who push the stroller will not kick the basket. However, from this test, the basket needs handle to allow the user to grab it easily.
2. Push the baby stroller and pull the shopping trolley
4. Put the shopping basket on the baby stroller umbrella handle bars
5. Put the groceries on the baby stroller shelter
These are few mock ups 1:1 for the basket/ panniers for the baby stroller. The first basket picture (top left and right) is the same size as the shopping basket in Woolworth, however, it is too big for the baby stroller. Whereas, the middle pictures of the baskets are the closer size measurement of the stroller basket.
Before designing, I have to know roughly about the volume (weight and space) of the basket that parents need for the groceries. I went to Woolworth and assume groceries for two days.
The weight is about 7.57 to 8kg and the size of the basket is 43cm length x 29cm wide x 25cm depth. However, one basket is usually not enough for family grocery needs.
Baby nappies and tissue paper take a lot of space in the shopping basket.
