2. PROJECT: OUTDOOR-BRAAI
COMPANY: MAJONI DESIGNS
START:
I’ve working as a Design Engineer at Hydrofire for nearly 2
years now and I decided to put my skills into something I can
call my own. Starting a brand of my own as I work for the
near future when I decide to make it into an Agency.
End:
After putting my skills to the test, I came up with the design
above. Everything that is made of steel is fully
manufacturable not just for illustration. I launched my design
on YouTube and so far I’ve gotten 3 customers with it.

3. PROJECT: STAINLESS STEEL-ASH CAN
COMPANY: HYDROFIRE
START:
We had a growing issue of ash burning our plastic bins as some of
the ash would retain its heat, without noticing would cause
unwanted holes in the bins, so to combat this issue I was tasked with
developing an anti-rust and heat resistant bin.
End:
I decided to use 304 Stainless Steel for its anti-rust properties and
made it a 30-liter capacity bin as we don’t really always have much
ash to throw away. I made it under the supervision of my Manager
with our CNC machines after I had designed it. The project was an
operational success.

4. PROJECT: STAIRS DEVELOPMENT
COMPANY: HYDROFIRE
START:
As stated before, the building had to be
renovated to meet our operational standard. The
current staircase proved to be too steep for
continuous use and so a new staircase that would
solve the “too steep” issue was needed. I was
tasked with its development and design.
END:
I designed the stairs in Autodesk: Inventor to be as
gentle as possible as the users will be on a daily basis
going up and down carrying loads that vary in weight
using my knowledge in Strength of Materials and
Structures, so by making the stairs not as steep as ones
before I was avoiding any future accidents that might
have resulted from the stairs being too steep. The new

5. PROJECT: COVERPLATE FOR FIREPLACE
COMPANY: HYDROFIRE
Start:
At Hydrofire we sell fireplaces. However, these fireplaces aren’t always
in great shape when we receive them so they need correctly by either
replacing a component inside too costly to import from suppliers or
updating/improving the current design of any component inside, which
End:
On a daily basis, I design and operate the machines used to laser
cut, bend, and assist In the installation of my designs. Above is an
example of this, it is called a coverplate, which is used to cover
space left in the fireplace area as seen in the picture on the right.

6. PROJECT: L&R BRACKETS
COMPANY: HYDROFIRE
Start:
At Hydrofire, flues are a major component of the business and so
having the most efficient and structurally stable installation is of
the utmost importance. There was a recurring problem of the
wind continuously blowing some of the flues/cowls off balance,
and I was tasked with developing something that’d solve the
problem.
End:
After some research, I came to the conclusion seen above. Draw it up
in AutoDesk: Inventor and proceeded to fabricate it under the
supervision of my manager. The final product was an operational
success.

7. PROJECT: PEGBOARD
COMPANY: HYDROFIRE
Start:
We needed the most efficient way possible to store our brackets, and I
was tasked with finding the solution the matter. After a bit of research,
I came to the conclusion that a Pegboard would be the best.
End:
I designed the above 2 Pegboards using Autodesk: Inventor and
proceeded to make them myself using our bending machine for the
handles and CNC for the sheet metal part under the supervision of
my manager. The project was an operational success.

8. PROJECT: PACKAGING CRATES
COMPANY: HYDROFIRE
START:
The crating used for courier used to be made on demand, until
I was tasked with finding a standard size that’ll accomodate
most if not all of the Fireplaces that require crating.
END:
I was able to achieve my goal and the Ops. Team ended
up using far less planks than they had been using before
the standardization which helped the company save
money on buying planks.

9. PROJECT: PUMPS AREA-CLOSE
COMPANY: FREELANCE
START:
I had a client who needed their heating pump area closed up
as his children would constantly play around there. To avoid
any future accidents he came to me to design something
that’ll keep the kids out but also be able to access the area
when he needs to.
End:
I came up with the design illustrated above and proceeded to
procure the tubing and wood required for the project,
enlisted the help of my contractor welder to assist in the
installation of the tubing and wood, welding where required.
The project was an operational success.

10. PROJECT: MEZZANINE DEVELOPMENT
COMPANY: HYDROFIRE
START:
I was tasked with developing and design the
mezzanine of both building A&B of
Hydrofire. The aim was to use my designs to
ensure the technical team had all the data
they needed to aid them in the installation
of the mezzanine.
DURING:
During the development, my main
responsibility was to weld, cut and
bolt down the I-Beams and
Channels together and assist with
the supervising tasks as I was the
one who designed it, so I had more
knowledge than the rest of the
technical team on the job.
END:
During the near end of the project,
had a meeting with all my
stakeholders to discuss the life cycle
of the project, as well the project
success. Long story short, all
objectives were met.

11. PROJECT: MUNYA CHIPUNZA FLOORPLAN
COMPANY: FREELANCE
Mr Chipunza was planning on building his dream home.
However, lacked sufficient data to make an informed RFQ to
an Architect, and so he came to me with a concept of how he
wanted his house to be. He needed the exact dimensions of
each and every room seen in the picture about put into
floorplan.
The floorplan took me above my average time to
construct in AUTOEDESK: INVETOR but was able to
complete it in time. Mr Chipunza was impressed enough
to tip me a relatively great amount of money and
assured me he would recommend me to his friends and
fellow managers in the company.

12. PROJECT: BUILDING 3D-MODELING
COMPANY: HYDROFIRE
START:
When the company purchased a new building. They needed
a digital 3D-model of the building to help visualise the
renovations that were to be undertaken to ensure the
building met the requirements needed for our operations.
END:
The new 3D- model proved to be essential to
the planning and development of projects that
came afterwards, such as the aforementioned,
mezzanine development.

13. PROJECT: LISEO OPERATIONS-STORAGE DEVELOPMENT
COMPANY: HYDROFIRE
START:
Hydrofire Operations Dept. required a detailed and
operational storage planning, which I was tasked with
developing and implimenting. After a few consultations with
the Ops. Team, we came to the solution above.
END:
The plan was an operational success with all
stakeholders happy with the end result.

14. PROJECT: WAREHOUSE STORAGE DEVELOPMENT
COMPANY: HYDROFIRE
START:
Due to moving to a new building with a
different size and layout than the one that
had been in use, a new layout of the stock
had to be developed. I was tasked with
working with the Operations Manager to
develop the best layout to optimize the
dispatching of the products in storage.
DURING:
Assisted in overseeing the
construction of the layout myself
and the Operations Manager, to
ensure it was according to the plan
we had devised.
END:
The Operations team that dispatch the
products was happy with the end result
that ensured maximum space
optimization. The project was an
operational success.
