Abstract
Description
[0001] In supermarkets and shops, you often see people bending over their shopping cart, working through their digital shopping list on their mobile phone.
[0002] After quickly memorizing most of the remaining items, the phone disappears back into the (trouser) pocket. Then the game starts all over again: phone out, item memorized, phone away.
[0003] Since my shopping list is exclusively digital due to technical kitchen aids, and I am often in this situation myself, I have been thinking about how I can attach my mobile phone to the shopping cart.
[0004] I had the idea to design an adapter that would be inserted into the horizontal coin slot of the cart and simultaneously unlock the cart from the other carts.
[0005] This adapter is screwed to a holder that allows you to adjust the angle of the smartphone on the cart. This way you can walk through the store with the cart, The phone remains on the cart during this time, and you can check off all items placed in the cart on your phone by tapping or swiping.
[0006] The holder is also a practical help at the checkout, as many people use apps or payment methods that are stored on the mobile phone.
[0007] Therefore, the mobile phone always remains within the user's field of vision and control panel.
[0008] The mobile phone holder for the shopping cart is customer-specific. It is not an object that is already permanently attached to the shopping cart.
[0009] Inserting the coin adapter unlocks the shopping cart, which then serves as a mobile phone holder for the customer.
[0010] After the cart is taken to the collection point, the mobile phone holder is removed from the coin slot. The customer then takes the phone holder back.
[0011] The prototype of the coin adapter is final. The phone holder is universally compatible with all phones, with or without a case, but can still be modified. Description of the parts shown in the pictures Image 1 - Coin adapter in 4 views, which is inserted into the designated slot on the shopping cart.
