Electrical Product Design Review: Laptops

1st January 2013

Through product-breakdown, WRAP has identified a number of cost savings and design improvements that can increase durability, reduce return rates and prolong product lifespan.

Overview

Overview

The case studies below describe how simple design changes and better customer information can achieve a net-positive result for businesses bottom-line.

Lightweight notebook laptop

Based on 100,000 unit sales per annum, savings were estimated to be:

~ £200,000 per annum

~ 373.3 tonnes of CO2e per annum

~ 167.8 tonnes of material per annum

Improvements Identified

During the teardown the following key areas were identified that would benefit from design and/or manufacturing changes: 

1.

Simplify design with fewer components and screws to reduce assembly and disassembly times.

2.

Avoid the use of adhesive to facilitate recycling by using reversible fixtures such as snap-fits.

3.

Change the manufacturing process to reduce the need for machining and waste of materials

4.

Avoid unnecessary moving parts to reduce risk of mechanical failure.

Top end business laptop

This case study describes the design review of a business laptop that has been cleverly designed with sustainability criteria at the forefront. This laptop has a number of features that facilitate component reuse, repair and segregation at end of life.

Improvements Identified

During the teardown the key positive design features were identified: 

1.

The most commonly replaced parts were easily accessible from the underside of the laptop, (i.e. battery, hard drive and CD/DVD drive);

2.

The back cover was clearly marked PC ABS FR40, and has achieved the desired strength and rigidity without using a magnesium alloy.

3.

The fan assembly is well-designed and securely mounted.

4.

All internal wiring has been kept to a minimum length and connectors are fixed firmly in place.

5.

The hinge design is excellent and well secured using brass inserts and heat stakes

6.

The LCD screen can be easily accessed once the front bezel has been unclipped.
