Hey guys it's me Eshvin. Unfortunately, this will be my last blog related to ICPDššš
I have thoroughly enjoyed blogging about my journey in ICPD and I am grateful that I can share it with my viewersšš
Although this is my last blog, this blog will be one of the most interesting experiences I had as I am going to walk you guys through my journey in making the PROTOTYPE OF MY CHEMICAL DEVICE!!!š„³š„³
DOES IT ALREADY SOUND EXCITING????š
For this week's blog, I will be talking about the theory related to Design Specifications & Prototyping which led to making my group's prototypeš š
Design Specifications A specification is a set of documented requirements to be satisfied by a material, design, product, or service. It is a common preliminary part of any engineering design and product development process.
Design specifications provide product design teams with the informationš they need to build out new features or functionality of a product.
Good design specifications allow product designers to answer the following questions,
- What are we building?
- What should the final build achieve?
- How do we measure successš?
Type of Specifications at the preliminary design stage relevant to product design;
Material Specification
Physical (dimension, weight, the voltage required, etc)
Functional/Performance Specifications
e.g. Acceleration from 0 to 100 km/h in 8 sec, 50m Water resistance
CA2 Report Part 5: Design Specifications Table
my group was tasked to create a design specifications table for my groupās chemical product which will be shown when I am going through my journey in prototyping ā¬ļøā¬ļø
What we have so far... ⢠A device idea based on chemical engineering principlesā ⢠A preliminary idea of what this device should be in terms of functionality and look (qualitative and quantitative specifications)ā ⢠Some idea on how the parts should come together and what mechanism is needed.ā
Prototypeš¦
Prototyping is an ESSENTIAL part of product design that comes after ideation, where the team has created and selected ideas that can solve usersā needs.
A prototype is a simple experimental model of the proposed product to check how well it matches what users want through the feedback to help guide development.
Why do Prototyping?š¤Ø
It allows the designer to:
Adapt to changes early thereby avoiding commitment to a single, falsely-ideal version and later incurring heavy costs due to oversights.
Show the design to the users to gather feedback to help pinpoint which elements/variants work best and whether an overhaul is required.
Improve time-to-market by minimizing the number of errors to correct before product release
Prototype Fidelity
Fidelity refers to the level of detail and functionality that is included in the prototype. The level of fidelity should be appropriate for presenting to users in user testing so they can give focused feedback.
Low-fidelity Prototype (e.g. cardboard) is fast and cheap to make. They are also easy to make changes. However, low-fidelity prototypes lack realism and hence may be difficult for the users to give feedback. They are usually very basic and lack interactivity, making it difficult for the user to imagine how they would use the product.
Now I will be going through the journey of creating this prototype!!!!!

Design Notes & Sketches
the sketch below was my group's rough idea of how the butter maker would look like

the sketch below shows the prototype of the butter maker my group made

1. Motor
2. Cover - T: 1cm, D: 14cm
3. Panel
4. Inner Cylinder - T:1.6cm, H: 15.5cm, D: 8cm
5. Baffles
6. Heating Element (Coil) - D: 11cm, H: 11cm
7. Thin Mesh
8. Outer Cylinder - T: 1cm or more, H: 17.5cm, D: 14cm
9. Cone
10. Solenoid Valve - L: 2cm, B: 2cm, H: 2cm
11. Base Cover - T: 1cm, D: 14cm
12. Outlet For The Pure Butter After Solenoid Valve - L: 2cm, D:2cm
13. Power Source/Plug

Photos & Videos of the Fabrication Process
the making of the different parts of the prototype
the printing of the cone
the cone is used for the butter to flow out through the square opening

the printing of the coil
the coil acts as a heating element to melt the butter

How the Product Works with the Use of its Mechanism & Operating Principles
Modifications of the device š”
The design to be able to remove easily like the cover and the inner surface of the cup to be able to wash and clean
The equipment to purchase is not that far; it can be easily accessed online and some shops in the convenience store that sell electricity for the sensor and solenoid valve.
Uses the non-toxic product
The product can last very long as it runs on a battery/ switch which also saves power and is energy efficient.
Operating Principles š
The device consists of a sensor, solenoid valve, filter/mesh, and a rounded shape compartment with a red coil around it. The mesh can separate the clarified butter or infuse clarified butter from the water and milk solids that will occur at the top of the procedure. By having a solenoid valve connected to a density/color sensor that is connected to a switch it will be able to drain out the product which is pure butter from the water and milk solids content without pouring or tilting it. The filter/mesh at the base separates the pure butter from the water and milkās solid content so the outcome will just be pure butter without any residue. The red coil around the compartment acts as a heating element.

Presentation
My group and I decided to use the Netflix Theme as our presentation as it will make the presentation less dull and we thought that it will attract our classmates to pay even more attention to usšš»
SUMMARISING THE WHOLE PROCESSš®āšØš®āšØ
Last but not least, I really appreciate the fact that I got the chance to work with Valerie, Asraf, and Insyirah šš.I know how strongšŖš» we are as a group and how fun𤪠of a group we are. This whole ICPD journey has been the most memorable one with them and hopefully, we get to work with each other in the other semesters š„ŗ.
just the hyper 4vengers peacing outš

That is it for my blog! Hope that you enjoy reading it!
My Journey for ICPD has officially come to endš©š©
Hopefully, I have inspired people along the way to try things like 3D printing or invent something that makes people's life easierš
It has been a great oneš„²š
