Lime Slicing Juicer

A Bartender’s Tool

Principal Design

A product idea by an international entrepreneur’s dream to launch a new product


Lime Slicing Juicer solves a simple problem by offering the convenience of slicing the citrus fruit as it is being squeezed, and allows the user to eject the spent rind halves with a tip of the thumb. This project sponsor is a seasoned entrepreneur who decided one day to become and inventor.

A prize for any casual cocktail artist or professional mixologist, the simple slicing juicer enables efficiency, reduces clutter and the need for knives and cutting boards, and features integrated and modular zesting tools. This is a great example of how to launch a product from a simple idea.

Concept Development

Inspired by the Inventor, “a hand squeeze juicer that cuts and juices limes at the same time”, the challenge to design the best solution drove qualitative research with lead users.

Functional Analysis

Establishing the basic specifications having ranked the value of feature-sets as dictated by quantitative analysis, we set off to sketch the possible futures within our framework. Our goal was to effectively launch a product.

Prototyping and Testing

Finally, we built, tested, and refined successive prototypes to test functionality, user impact, and the potential material performance of both plastics and metal. To launch a product like this we focus on the end user and the geographic market.

While the product development process can be customized to apply effectively to the needs of the customer and adapt to changing business objectives, Principal Design’s 5 step process is a framework to launch a product guided the design team and encouraged communication and innovation.

design process

The success of our product design process for product development and ultimately to launch a product depends on a purposeful, user-centered design approach. Principal Design’s methods reduce risk while balancing exploration with execution with the goal of achieving innovation and intellectual property protection. Our creative strategy is divergent to leverage resources and discovery, and convergent to select for the best opportunities. Each stage of the process is an opportunity to reflect on and refine the design and specifications of a new product launch for the greatest impact.
