“…what inspires me is the creation of designs which really do make the world
a better place”.
From an early age I have always been captivated by engineering and design and the mechanics of how things fuse together to create
works which are both aesthetically pleasing and highly functional. It was this passion which saw me undertake a tertiary education in
Mechanical Engineering and then pursue a career the field.
In 2008 I joined a sheet metal fabrication, manufacturing and design company in Cape Town which offered both a position of
responsibility and exposure to clients which enabled me to become a highly capable and proficient designer, engineer and
draughtsman.
Understanding the needs of a client and being able to produce both the design and manufacture to suit has given me great satisfaction
and has increased my hunger to make my next move to the next challenging position to demonstrate my abilities.
Outside of the workplace I have sought sanctuary from my interest in engineering from cars and remote controlled hobbies; not only
have I completely rebuilt the engine on my car and serviced and upgraded many of the parts but I have also serviced and repaired
friends cars, installed countless car radio and sound systems and assisted a friend on a project Caterham kit car. I have also had a
great interest in radio controlled hobbies (Planes, helicopters and cars) and have worked for a year and a half in the industry and have
had many models my own recreation and repairing.
I think what inspires me is the creation of designs which really do make the world a better place, things which you can really can get
excited about. It is these world changing designs, designs such as the internal combustion and jet engine; bullet train and maglev
train; to the Millau Viaduct bridge, which inspires me to progress further in my field of engineering design to be in a position to create
or be apart of such a design myself.
Over the next fourteen pages you will get a taste of the projects that I have worked on over
the last three years, which I hope will demonstrate my abilities.
Martin A. Nilsson
Client: BP and Wild Bean Café
Brief: To design a wall mounted illuminated flex-face sign for Wild Bean Café – a café which operates out of all BP service stations in and around South Africa.
Final Product
I initially designed this sign to be illuminated via a string of LED lights to provide an efficient whole life cost, however through a Value Management exercise the client wanted the most economic solution; I redesigned the sign to be illuminated with eight fluorescent tubes to fulfil the clients requirements. Other challenges included designing a quick release front panel to replace burnt out tubes and designing brackets to hold the ballasts. Since the initial project, BP Garages increased their order to have the sign rolled out to all new and refurbished Cafes across South Africa.

Client: BP
Brief: To design an aerofoil profile shaped sign to be placed at the entrance to the BP Technology Centre in Kyalami Johannesburg.
The first challenge I had with this project was the time given by BP to design and complete the sign which had to be ready for the ribbon cutting opening ceremony of the new Technology Centre which the sign would be in full view of all the top BP directors.
Even though the final size, shape and finish of the sign was critical it was left up to me to design the sign cost effectively and within a tight deadline which meant it also had to be easy to manufacture. I designed this one-off bespoke sign to consist of: • a bolt cage; which is
submerged in concrete underground.
• an inner frame; to give it rigidity, and
• outer cladding; to create the final aerofoil shape.

Client: BP
Brief: To work in a team of 4 to design a 14 meter and 7 meter high BP Pylon with LED Pricing panels
Final Design and Installation The design started with the division of tasks; I decided on taking up the task of designing the ‘BP express’, ‘BP Ultimate’, and ‘Wild Bean’ panels of the pylon. The challenge in this project was matching the design of the panels to fit the frame - which was still in the design process - and the attachment brackets to the frame. The 14 meter pylon was designed first because this project unfortunately was also to be designed to a tight schedule before the opening of a new station along the national N2 highway near Sir Lowry’s Pass in the Western Cape.
The design took longer than expected leaving an almost impossible manu-facturing time. This is when I took on the role of fabricator/ assembler/ manufacturing manager in the workshop for a couple of weeks to ensure the manufacture and delivery of this project on time.
Local Newspaper Clipping
Client: Cape Winelands District Municipality
Brief: To design an internet
kiosk for the Cape Winelands District municipality aimed at providing internet facilities to the underprivileged farm workers of the
District community.

I was initially briefed in this project by being given samples of the various computer components that were going to be used in the kiosk, and was asked to design a free standing kiosk to accommodate these components. Continued….
Client: Cape Winelands District Municipality
Brief:. To design an internet

District community.
First Prototype
Final Production
The client gave me a lot of flexibility in the design of this kiosk as they were not set on the ‘look’ of the final product. After a couple of sketches, the design you see here was approved and 25 of these kiosks were installed in and around the Cape Winelands District area.
Final Prototype
The components which I had to design this kiosk around included a stainless steel waterproof keyboard and touchpad mouse, a 15” Samsung flat screen, a small computer casing which housed a dual core processor and modem and a UPS battery pack. Using these components, it was important that the design of the free standing kiosk was ergonomically suited to accommodate both a person of average height as well as a wheel chair bound individual.
Client: ACSA
Brief: To design an illuminated
advertising board for
Airports Company South
Africa (ACSA) to be placed
in all airports around
South Africa.
Final Product
3D design and exploded View
The criteria for this sign were that it had to be illuminated and accommodate an A0 aluminium advertising snap frame. In the design I wanted to stay away from welding and fabricating as much as possible to keep the overall assembly time of the final product to a minimum, this also resulted in a more cost effective method which the client was very appreciative of.
The final sign was a bolt together design. All the bolt-together components were also symmetrical from left to right reducing the parts list and easing assembly.
Client: Exel Service Station
Brief: To design a brushed
stainless steel ‘pump
island surround’ for all
the new Exel Service
station sites ,as well as
refurbished sites, in and
around South Africa.
Final Product
Computer Design
I had to design the pump island surround according to the Exel specifications. The concept was to lay the surround on the site and fill it with concrete creating the surround on which the pump will be placed. The challenge with the project was that the finished component was seven meters in length and there was a fear of it warping under the weight of the concrete. It therefore needed sufficient supports which would not interfere with the inner workings of the pump. I created a design which incorporated strategically placed triangular supports on either end to overcame this.
Client: In House Design
Brief: Completely redesign the cool drink can dispenser and modify the design of the refrigeration unit of the 3rd prototype vending machine, a machine designed and built at SPT to be their flagship
product.
This project was started in 2007 as an internally developed vending machine to approach the vending machine market as the only vending machine designed and built in South Africa. The design brief was to create a state of the art refrigerated vending machine that could vend cans of cool drinks as well as confectionaries, able to accept bank notes as well as currency, have GSM capabilities so the machines owner could check stock with a mobile phone and the final machine was to compete pricewise with the Chinese and Italian vending machine market - where majority of the South African Vending machines being sold in South Africa were coming from.

Client: In House Design
Brief: Completely redesign the cool drink can dispenser and modify the design of the refrigeration unit of the 3rd prototype vending machine, a machine designed and built at SPT to be their flagship
product.
I took over the role of design engineer two years into the project before the 3rd prototype was built. As there were glitches in the soft drink can dispensing units and the Refrigeration unit, it was my task to redesign, build and test these components until they ran perfectly for the 3rd prototype machine. The new redesigned can-dispensing unit was a completely new and bespoke design that basically used 3 main sheet metal components pop riveted together resulting in a component that was 5 times less expensive and more reliable with than the dispenser unit on the 2nd prototype.

3rd Prototype
Client: In House Design
Brief: To design a confectionary, wall
mounted vending machine for
use in venues with limited
electricity supply.
I based the design on the theory of taking the dispensing spirals, already in use in the confectionary trays of the large main vending machine, and attaching them to mechanical rotary coin acceptors (in use with bouncing ball or gum ball vending machines) thereby allowing the dispense of products only after the correct amount of change was inserted in the coin acceptor. I then designed a wall mounted lockable display cabinet with a coin box and product dispensing chute that housed 5 of these spirals allowing the dispense of 5 different products.
This machine could then be placed almost anywhere vending products at a fraction of the price to the owner than the standard vending machine, but its limited to ambient temperature confectionary
Computer Design
Client: City of Cape Town
Brief: To design an illuminated
sign for Cape Town’s new
IRT (Integrated Rapid
Transit system) Bus
Stations. The signs were
to be placed at all the
new bus stations in and
around Cape Town.
Computer Design and colour scheme
Shield Design I had to design a sign made of sheet metal cladding to cover existing poles already designed by architects and already installed on 14 sites. The challenge with this project was the fact that after the design of the sign was finished to a tolerance of 2 or 3mm, it was found that the architects had as much as a 20 millimetre tolerance in some of the critical sign attachment points over the 14 sites that were measured. Continued…

Municipality
Brief: To design an illuminated
sign for Cape Towns new
IRT (Integrated Rapid
Transit system) Bus
Stations . The signs were
to be placed at all the
new bus stations in and
around Cape Town.
Final Product
The brackets holding the sign in place had to therefore be a lot more adjustable with large slotted holes in order to overcome the large tolerance, and filler plates had to be designed to fill gaps cause by this excessive adjustment therefore making each sign fit each pole uniquely.
Client: Drew for my own interest in my own time.
Brief: Drew a working 3D model of the Wankel Rotary Engine in Solid Works 2010.
But after a couple of weeks of modelling I got a bit carried away and ended up modelling everything from the stationary gear to the inlet ports, exhaust ports, spark plugs and water jackets in the casing to the seals, bearings and gear in the rotor all the way to the eccentric shaft and flywheel.
I sketched and modelled this rotary engine to better understand the Wankel rotary internal combustion cycle and better understand the drawing of the rotary casing using an Epitrochoid curve.
