What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

About

Do you know anyone who never struggles opening a jar? We're still looking for him/her...

We've tried every jar opener available on the market, but none of them worked really well. That is because these tools:

  • Provide grip on the lid, but you still need to hold the jar
  • Still require you to use a lot of force to unscrew the lid
  • Can only open jars with vacuum

The solution

We introduce the Quopener - the new effortless way to open jars. It is designed to open any shape or size of jar, with or without vacuum. And most importantly: You don't need to hold the jar or the lid!

The Quopener offers all essential jar opening features combined.

Easy to use, regardless of age or ability

The Quopener helps anybody to be independent in the kitchen and is very easy to use:

     1. Place the Quopener on a jar

     2. Push the handles

     3. With very little effort the jar opens and you can remove the lid

Place, Push, Open

Technology

After placing the Quopener on a jar and pushing the handles, several things happen in a matter of seconds.

The small push force from the hands is translated to a much larger clamping force on the lid and the jar. When this clamping force is high enough, the friction between grips, jar and lid is sufficient to avoid slippage. The preload of the spring ensures that no rotation will happen before that time. After applying a bit more force, the spring begins to elongate. This spring elongation allows the two clamping parts to rotate relative to one another, also rotating the jar and lid in the opposite direction and opening the jar.

Design

The Quopener features a minimalistic design that will fit every kitchen, and has been nominated for the 2019 German Design Award. At first, we will offer the Quopener in one color configuration. We will let our backers vote for the first color configuration. If we reach our stretch goal, we will be able to manufacture extra colors for you to choose from!

Designed and manufactured in Europe

The design has been a process of many years research and development, and many design iterations. Since the early plywood prototypes, the Quopener has evolved into a product that we are now ready to present to the world. Over the years new technologies have become available to us, such as 3D-printing, which have rapidly improved the design process in the final stages of productdevelopment. We've always been searching for the best possible ways to bring our ideas to life, resulting in lots of experiments with different materials and production methods.

The production version will be made by injection molding. We've selected an experienced manufacturing partner in the Netherlands who will optimize the design for mass production, fabricate the molds and handle the production and the final assembly. The custom-made spring will also be produced in the Netherlands.

Rewards

You can order various Quopener packages. We'd really like to encourage you to select one of the very attractive multipacks. Why? Because you probably know people around you who will be very happy with a Quopener too. It makes a great gift! And...the product and shipping rates are so much better for the gift packs.

To make the project fly, we will initially offer the Quopener in a standard color combination, but we really would like to offer more color options. So once we reach the stretch goal of 90.000 Euros we will be able to offer more color combinations.

About us

We, father and son, have joined forces to create what we believe is the best jar opener in the world. Both of us have an engineering background (mechanical, industrial design & biomedical engineering) and we love to create and do all kinds of DIY projects.

Our interest in engineering, design and product development has brought us to a stage where we now want to share our invention with the rest of the world. 

Since we started this project, we have learned something new every day. From using sophisticated design tools, to the secrets of injection molding. From cost estimating to video making. It has been a super exciting journey. And we are not there yet. To really bring this project to the next level we will have to work hard to expand our knowledge in areas such as marketing, communication and retail. We can't wait!

Timeline

Risks and challenges

After putting our project online, a new and exciting phase will start (we hope...first we have to reach our target).

We are fully aware that we have a big responsibility towards all our backers to make this project a success. But, like all other projects, there are always some risks. Typical risks that you see in projects:

- The project takes longer than expected.
- The quality of the product is not good

Although we can't rule everything out, we have made conscious choices to reduce these risks. Unlike many projects, we will not produce in low-wage, low quality countries. The entire design, production, assembly and shipment will be done in the Netherlands. Our manufacturing partners are very experienced companies who produce the best quality products. Because everything will be done in the Netherlands, communication and logistics between ourselves and the supply chain will not be a problem.

Our prototypes have been thoroughly tested and function exactly as desired. However, there are always some uncertainties when you move from prototype to real product. Some final choices still need to be made, e.g. material selection, but all this is part of the normal manufacturing design process that we will kick-off as soon as we reach our funding goal.

We are committed to make this project a great success and we are looking forward to get your valuable input and support!

Many thanks!
