Lok Helmet Lockable bicycle helmet for students

A bicycle helmet developed for the student population that tackles two prominent issues. Firstly, users are frustrated about what to do with the unwieldy helmet when they reach their destination. Second, there is a conflict between the sporty, aggressive aesthetics of the helmets currently on the market and the fashion sense of today’s urban student.

This is a group project with team members Sandhya Kumar and Casper Sudak. All renders and sketches are my own.

Whirl! A fun waterbottle for kids

The Whirl! is a fun water bottle for kids that has a water wheel in it that spins as the child drinks. Children often lose water bottles, but rarely lose sight of their favourite toys. Adding a playful feature to a water bottle greatly lowers chances of the bottle getting lost.

The water wheel comes off with the lid for easy cleaning. The bottle will be made out of blow molded PETE and the Lid/ wheel component out of injection molded PP.

Tippo A quirky watering can for you garden.

The Tippo is a watering can designed for people who enjoy elements of humour or quirkyness in products they purchase.It has a form reminiscent of an elephant or a pig that that is subtley comical.

The design will need to be rotomolded out of Polypropylene plastic for the desired surface finish and durability.

Beluga An intuitive sampler for beginner musicians

The Beluga is an electronic instrument that has a simple, intuitive interface. It resembles a maracca, an instrument many inexperienced musicians gravitate towards, and functions similar to one. The beluga has an authentic ‘weight’ to it and also has its own uniqu acoustics thanks to the sound box. Most electronic instruments on the market do not have these attributes.

Thank you for your time! There are three traits that I have always had that led me to industrial design. I like working with my hands, I like figuring out how things work, and I like figuring out people.

Good design begins with empathy and ends in a thoughtful and effective product with a definable character (fun, ordinary, whimsical, etc.) Designers must be willing to step into their users’s shoes and understand where they are coming from and their specific requirements. Communication is key and the act of finding the problem should be treated like a design problem.
