The Unbent is modeled after the familiar granny cart that many elderly citizens find quite useful in a range of situations. Wu Yun-Ci and Lin Chi-Hung recognize the convenience of such an object, but they realized that it could be greatly improved upon to enhance practicality for the aged.
There is an unexpected mechanism worked into this shopping trolly that comprises an elevating base, a pumping foot pedal and a release button in the retractable handle. When one's grocery-buying begins, the inner tray can be lifted, affording the easy placement of items. Gradually, this can be let down as the Unbent shopping cart fills. While passing through the checkout, simply raise base of the basket to empty it without straining your back.
