PROBLEM:

Many space heaters project heat ineffectively and have ambiguous controls.

GOAL:

 

1. Design a compact space heater that can disperse heat over a wide area. 

 

2. Create a simple UI with tactile and visual user feedback.

CONCEPTUALIZATION

VERSION 1

My ideas for the overall shape can be broken down into two broad versions. Shown below, the first uses a disproportionate hexagon-shaped footprint to project heat through three different channels, using three different heating elements.

I ultimately pulled the plug on this version because of its boxy aesthetics and over-designed shape. While well integrated, the handle is far behind the center of mass, and would cause the box to swing when picked up. In addition, the excess of internal components add weight and cost.

VERSION 2

Here I tried to minimize design while focusing much more intensely on the elements of the shape that represent the human interfaces, such as the handle.

Instead of using three different air channels to spread warm air over a wide projected arc, I decided to use a diffuser instead, similar to those used at the ends of air ducts. In order for this to be possible, the grille had to wrap around the sides of the heater.

In these cross-sections, the motor, heat element and diffuser are visible from back to front respectively. The diffuser is suspended by two struts with a welded connection to avoid contact with the grille.

There are three buttons, each with extruded icons for tactile feedback. There are two settings for fan speed (high/low) indicated by white LEDs, and three settings for heat (high/low/off) indicated by red LEDs positioned next to each button.
