Helloo!! Welcome back to my blog👋. This is my last blog where I will be documenting every step of creating the product from preliminary ideation to prototyping.
So what is prototyping?
Prototypes are simple experimental models of a product that is scaled down and made from low-cost material such as cardboard and at the same time able to display their function and showcase the product on a physical 3D scale. This also helps the designers to have a better view of how the chemical device is going to be implemented.
Before moving on to the prototyping, we have to specify the design specifications so that the designers would be more clear on the functions of the chemical product. Design specifications is a set of documented requirements to be satisfied by a material, design, product, or service.
Needs Identification:
To start off, we decided to make a bathroom odour remover device mainly for household use because odour might be left lingering in the air for a long time after someone uses the toilet and it isn't nice when the next person uses the toilet and the smelly odour is still there. So to prevent that we need a device that is able to help remove the odour to prevent smelly toilets.
Design Specification:
Product: Bathroom odor remover
How it works: the gel is placed inside the container and over time it will absorb odors from the bathroom it is in.

Materials needed for the absorbing element include (side note: we are not going to make the gel absorber) :
Gelatine - to allow the mixture to harden to become a gel
Essential Oil - to provide scent
Table salt
Baking soda - main absorbing component
The operating principles of our chemical device is mainly on the gel where gas adsorption is used.
The gel is placed inside the container and over time it will absorb odors from the bathroom it is in.
Sketches and cutting process of our device:
Below is our first design which is basically just like a container with holes at the top to allow the gel to absorb the odour

This is the longer outer side of the container.
This is the shorter outer side of the container
The inner shorter sides of the container
The inner longer side of the container.
However, considering the sustainable design, we have implemented a slider to cover up the top holes when the gel absorber is not in use for example if we travel and the toilet is not in use, we can slide on the slider and cover up the holes so as to prevent the gel from drying up easily and can last longer.
This is the longer inner side walls with a space cut out so that we can fit in the slider.
Cutting off the space for the slider
Sketch of the slider
For the teeth of the gear and slider, we realized that we can actually use the flute of the corrugated cardboard to act as the teeth so that we do not need to cut the teeth of the gear and slider out one by one. So what we did was just to cut out a 15cm x 1cm strip of flute and glue it on the edge of the slider.
The inspiration on how to make the teeth of the gear came from this youtube video from 5:30 to 5:58
We have also included 2 gears as our mechanism at the inner side walls of the container so that we can roll the slider in.
We have cut out the 2 sides of the gear and we are going to wrap the strip of flute around the 2 pieces of circles to form the gear
This is the cover of the container with holes of 2.5cm in diameter
Cutting out the holes of the cover
Yayy!! we are done with all the cuttings and here are all the pieces:
Now, let's move on to the assemblingpart:
Assembly Process:
poking the toothpick through the walls of the container so that we can attach the gear to it
TADAAA!!! WE ARE DONEE!✌ Here's the final product look of our device

You can watch the video below to see how the gears work to turn the slider in and out of the box:

I had fun creating this prototype although it took me a lot of time to visualise how to design the device and also assembling the different parts together but creating this prototype allows me to understand more about the importance of us creating the prototype.
Overall I feel that throughout this module, I've gained a lot of new skills and knowledge about CADD drawings, 3D printing, and creating the different types of joineries using cardboards. These skills that we have learned allowed us to use them and make prototypes out of them🤡
SOo YEA! That's the end of my blog😞 I hope you guys enjoyed reading all my blogs. Thank you and byebye👋
