Persona

James, 26

Seattle, WA

Likes to ride his bike to work and for other errands. In the winter it gets dark around 3:30, and he won’t be leaving the office until 5:00. James also likes to use his phone to navigate while he rides. Cyclo Charge offers James a trust worthy bike light and phone charger that comfortably displays information and never runs out of battery.

Look after the bicycle and the bicycle will look after you_.jfif

How it Works:

A magnet on the spokes passes by a sensor on the fork of the bicycle, and with each rotation sends charge to the phone and headlight

Feature Decisions

Proof of Concept

A company named arara has created a spoke mounted, battery free light that is charged by induction. The magnet continuously passing by the sensor on the fork charges the light. I used this same principle in my design.

Initial Ideation

With these sketches, i was deciding on how the product would generally look, and how the phone might be secured.

Securing the phone

Types of Securement (Chart)

I made this matrix to compare all of the ways phones can be secured to surfaces, and this helped me to decide on which securing system to use.

Secondary Ideation

Deciding Size (Chart)

I started by recording the sizes of all of the iPhones that have wireless charging capabilities.

I did this so I knew how large I had to make my models.

Mockups

Six initial forms for the bicycle mount, based on my initial sketches.

Refined Mockups

I started playing around with this shape because I found it to be clean and versatile for many bicycle styles. These mockups determined the shape of my final model.
