Production Technology

Ztraw is manufactured with injection molding; after the polypropylene component is solidified, it is then placed in another mold to inject thermoplastic elastomers for the soft joint of Ztraw. We have to make sure the placement is precise or it will affect the vacuum suction experience of the product. For the pouch, we have laminated two types of materials together, PU and PEVA to make the internal wall of the pouch waterproof and not affect the appearance of the pouch. However, the PEVA makes it hard to attach the magnet and we have to figure out a way to secure it. So we found a special glue and a vacuum-formed plastic case to secure the magnet. Making sure the case has enough surface area and looks good on the pouch.

Design Challenge

Since the shape and folding methods of Ztraw is very hard to achieve without using actual production methods. In order to finetune ZTRAW's design throughout our journey, we have to build a new injection molding mold for each correction, which is a very expensive but accurate development process. Therefore, we have joined Kickstarter, hoping to gain more support to our journey in discovering the most convenient reusable straw in the world. Since Ztraw is a foldable straw that can be unfolded flat, it is very hard to create an airtight structure to have a similar user experience as a normal straw. We have tested so many prototypes with less than 1mm difference to achieve that and it requires high precision during production to minimize any percentage error.

Project Duration

The idea came to us in 2018 January and we have officially launched it on Kickstarter on 2020 March. The production begins in June in our chinese factory and then sent to Hong Kong to be assembled by St. James' Settlement sheltered workshop. The product starts sending out to buyer in 2020 July.

Operation Flow

Ztraw comes in a flat pack packaging to minimize the the carbon footprint during transportation and limit unnecessary use of extra materials. To use Ztraw, first you fold up Ztraw according to the vertical line along the body. Then you can fold it up into a triangular shape so that the first and last sections overlap to secure the flat surface into a drinkable straw. To carry it around, simply unfold the straw to wipe with towel/tissue and fold it in half and put Ztraw in the pouch provided.

Research

We have done research online on existing problems with reusable straw and we have tested out quite a few different designs from the market. The most common problem with existing design is that they are hard to clean and will trap molds on the internal walls. So we looked at existing reusable straw that can be popped open and found out that in order to counteract the possibility of air leakage with an open structure, they are mostly bigger in size with hard material to create a stronger structure or uses soft rubbery materials to conceal the opening but making the straw less sturdy. We also found out that a lot of people think green products lack style. In the age where aesthetics is everything, green products do not stand out like other products at first sight. Therefore, we found a market gap for Ztraw where there are no sturdy but compact straw that can be opened up for easy cleaning. It's hard for people to take the first step and begin a sustainable lifestyle because it looks hard to approach and it lacks user experience. So we have created Ztraw with these in mind.

Inspiration

At least 37 countries are planning to restrict the use of single-use straw, which leads to the popularity of reusable straw. However, reports have shown problems with reusable straws from hurting people physically to trapping mold and causing sickness. This results in a market gap where people need straw but they are worried about the quality of the straw they were given. We wanted to change the belief that it is hard to maintain a green lifestyle by making our product simple and user-friendly.
