TECHNICAL REPORTS:

A series of reports and exercises that explore product design essentials, such as materials, manufacturing techniques, structural mechanics, and physical computing.

Exercise 1: Materials & Manufacturing – Hair Dryer

It’s important that any product designer has an understanding of materials and manufacturing techniques that are available/ The choice of materials and manufacturing technique not only affect the aesthetic of the object, but also the durability, cost and recyclability.

In this report, I’ve broken down an object – in this case a hair dryer – to understand the role of materials and manufactuirn gin product design. This report consts of:

1. A highly accurate 1:1 carbon copy model of the object.
2. Exploded view of all components
3. Analysis of manufacturing techniques
4. Resin Casting

Exercise 2: Structural Mechanics – Mechanical & Physical Properties

In this exercise, I’m a part of a design team responsible for the design of a pick-up truck’s chassis. The document below briefly descirbes each of the following properties will be in th ematerial selected for the chassis.

• Density
• Young’s modulus
• Yield strength
• Ultimate tensile strength
• Toughness
• Fatigue strength

Exercise 3: Structural Mechanics – Cantilever Beam

In this exercise, I designed, built, and tested a cantilever beam. The aim was to make the beam as light as possible and deflect as little as possible when loaded with a standard load at the free end.

This goal could be achieved by taking into consideration materials and the structural choices of the beam’s design. My design was made with lightweight MDF, laser-cut with a honey-comb structure.

Exercise 4: Physical Computing – Smart Object

In this group project, we designed a presence notification system which is shared amongst shared flats up to four people.

Some students living together use systems to let each other know who is present or absent in the flat, mainly for safety reasons. This project modernized this indirect interaction between flatmates to make it effortless.

The presence notification system is made up of two artefacts: a smart shoe-rack, and an accompanying presence status display box.
