People's choices will favor cost-efficiency, circular economy, and renewable natural materials. Whether purchasing themselves, OR having food delivered, e.g. groceries, an ice cream cake, or hot take out dinner, people will like a multi-purpose (cold, hot, or ambient) carrier bag for food transport and delivery. When quality lightweight insulation is proven to maintain inner temperature in such a bag, it WILL be chosen over more expensive, power-consuming "active cooling" delivery options.
A Helios bag's superior insulation lets it maintain inner temperature for 12-18 hours. It's multilayer shell incorporates recyclable moisture-block nanoengineered bioplastic, insulation of cellulose (bamboo/plant origin), and a puncture-proof exterior from recycled Kevlar vests or Tyvek. Travels well hand-held or shoulder-slung. Has a self-retracting cable lock that allows pass-through and securing to doors, doorknobs, etc. Has a slide compartment that fits chilled balls, for longer cold times.
Conventional hard-body cold boxes may have a higher empty weight, are often inconvenient to walk with, and can be a trip hazard if left at a doorstep, especially in a narrower corridor. They often use plastics or insulation that are environment-unfriendly.
When the bag is being filled with items, the shopper can put water-filled chilled or frozen balls (cryoballs) into the adjacent slide compartment. Cryoballs may also be put in later, before a bag is delivered to a doorstep. The bag and the main compartment's zipper are secured by the cable lock.
A Helios bag's flexible, multilayer walls minimize heat leakage, as well as moisture entry, air passage, etc. Cryoballs can be slid in or out, without opening the bag's inner space. Eyelets in the bag, the zipper, and the cable lock help keep the bag and its contents secure.
Cryoballs may be dropped directly into the bag from the freezers/dispensers. "How many balls?" depends on the anticipated duration items shall be in the bag, temperature recommended, the prevailing local temperature, etc. Once emptied, bags may be returned at the next delivery event, or to stores.
Hi Sarkar, different temperature boxes in the same device is a good solution. waiting for more details about handling, safety... etc. Good luck :)
Hi there, I can only agree with mentioned, putting everything in one box may not be ideal due to different temperature requirements. Looking forward to see how you'll develop it.
good luck
Dear Sarkar,
Congratulations for being the second one to submit in this challenge! I understand that your idea and concept is work in progress, including the product (I am assuming the image you've used is just a placeholder, right? because this is also a product design challenge)?
I like the courage of your concept: "from the distribution point to the delivery chain and all the way to the kitchen, where products can be transferred to fridge, freezer or countertop/floor as appropriate. " - so this is a one solution fits all, right? I understand the objective. The actual solution needs work now.
Good luck & have fun! Diana
