1. Typically, the frame of my hand truck is quite small, making it very inconvenient-and unstable-when transporting large items. The frame could be improved by designing it to be freely extendable and retractable.
2. To ensure ease and minimize physical effort when pushing the cart, the push handle assembly could be designed to fold up and lock at a specific angle.
3. Pushing a cart downhill can be a very frustrating experience; one careless slip can easily result in the cart tipping over. This is a sentiment likely shared by anyone who has ever used a hand truck-particularly in crowded environments like train stations. To alleviate this stress, a braking mechanism could be added to the cart to provide greater control and safety during descents.
