In your report, you are expected to mention the following points: o Importance of the topic and why you chose it (e.g. I chose digital keyboard keys because I need to fix my brothers keyboard and trying to find cheapest and best performing material, or every year this many people dying from heart disease so I chose heart stent material etc.).

QUESTION

In your report, you are expected to mention the following points:

o Importance of the topic and why you chose it (e.g. I chose digital keyboard keys

because I need to fix my brothers keyboard and trying to find cheapest and best

performing material, or every year this many people dying from heart disease so I

chose heart stent material etc.). Your chosen topic has to have a meaning for you.

If your topic is not original and no purpose is clearly stated in choosing that topic,

I will cut marks.

o Properties you are looking for in that component (e.g. it has to absorb energy, it

has to be strong and stiff, but it has to be cheapest or environmentally safest

option, etc.) You need to prepare the table for the translation step.

o Your approach to the material selection problem, your material indices (don’t

need to show derivation), the material selection charts you chose to apply your

material indices, and candidate materials. If you choose wrong material indices or

missing material indices, you will lose significant points.

o Supporting information from literature to support your material of choice (e.g.

after my material selection procedure I chose carbon-carbon composites to be the

best option and my literature review shows that this indeed is the commonly used

material for this application). I’ll ask you information to check if you did literature

review and if you cannot answer my question, you will lose points.

o How you chose to process your material of choice using process selection charts

and literature information supporting that process.

o You will need to generate the charts yourself using the software. I won’t accept

print out charts. Be creative and generate desired charts for your own problem.

Your report might cover the following titles (minimum 4 pages):

ü Introduction

o The reason you chose this topic, and the importance of it etc.

ü Required properties for the component

o Summarize all the properties that your material should have for that application

supporting with the literature (e.g., non-toxic, strong, high fracture toughness,

high fatigue life, high service temperature etc. together with reasons behind it.)

ü Materials selection procedure

o Design requirements in a table (function, objective, free variables, etc.)

o Material index and its derivation or refer to appendix for the correct index

o Application of material indices on charts

o Candidate materials and literature support

ü Processing selection

o Use process selection charts in order to make your process selection

Cost and environment

o Talk about the cost of your material and compare it with other possible candidates

using cost charts or literature findings.

o Talk about the environmental effects of choosing this material. e.g., Is it

recyclable?

o Use embodied energy charts or embodied energy data from appendix to rank

materials

ü Conclusion

o A paragraph of summary

• The report should be based on properly applied material selection procedure and

conducted literature search.

• All students are required to list references for the information provided.
• Format is not important but it should not be sloppy and each section is clearly separated

with a title.

• Show your work on the material selection charts.
• Apply your knowledge from lectures and homeworks to your project.
• Copying and pasting from your presentation and submitting it as a report is not

acceptable. If you copy exactly your slides, you will get low score. The content of

presentation and report are the same but report should include extra information

whereas presentation should just be the summary of your report.

• Some important point about the print out material selection charts is that when you apply

your material index to the chart, the best material for example can be composites. But

charts don’t specify what type of composite it can be so you will do literature search and

support your finding and at the same time you can find a more specific name to your

composite material selection such as Kevlar fibers in epoxy etc. Or charts might guide you

to Ti alloys but with literature search you can find a specific Ti alloy.

Material Selection for Digital Keyboard Keys: A Comprehensive Analysis

Introduction

The purpose of this report is to outline the material selection process for digital keyboard keys. The significance of this topic lies in the need to identify the most suitable and cost-effective material for repairing keyboards, ensuring optimal performance and longevity. By undertaking this study, we aim to address the key challenges associated with material selection, considering various properties, cost factors, and environmental considerations.

Required Properties for the Component

In order to select the most appropriate material for digital keyboard keys, several properties must be considered. These properties include durability, wear resistance, elasticity, and cost-effectiveness. Additionally, the material should possess good tactile feedback, be non-toxic, and exhibit high fatigue life. Through an extensive literature review, we will explore the importance of these properties in relation to the performance and longevity of keyboard keys.

Materials Selection Procedure

To approach the material selection problem, we will employ a systematic procedure that involves identifying the design requirements, deriving relevant material indices, applying material selection charts, and evaluating candidate materials. A table will be constructed to summarize the design requirements, including the function, objective, and free variables associated with the keyboard keys (Goh et al., 2017). The material indices, which have been derived specifically for this application, will be utilized to evaluate potential materials.

Supporting Information from Literature

We will gather information to support our material selection process through an extensive literature review. By reviewing existing studies and industry practices, we aim to determine the commonly used materials for digital keyboard keys and examine their performance characteristics (Nowell et al., 2017). This literature review will provide empirical evidence and insights to support our material choice, ensuring that our selection aligns with established best practices.

Processing Selection

After identifying the most suitable material for digital keyboard keys, we will determine the appropriate processing method. This decision will be guided by process selection charts and supported by literature information. By considering factors such as manufacturing feasibility, cost, and material properties, we will select a processing method that optimizes the desired characteristics of the chosen material.

Cost and Environment

An analysis of the cost and environmental implications of the selected material will be conducted. This will involve comparing the cost of the chosen material with alternative options, utilizing cost charts or relevant literature findings (Bayram & Greiff, 2023). Additionally, we will assess the environmental impact of the material, focusing on its recyclability and embodied energy. Embodied energy charts or data will be utilized to rank the materials based on their energy consumption during production.

Conclusion

In conclusion, this report outlines the material selection process for digital keyboard keys, considering various properties, cost factors, and environmental implications. By systematically evaluating design requirements, deriving material indices, applying material selection charts, and conducting a thorough literature review, we aim to identify the most suitable material and processing method for keyboard key repair. The incorporation of cost and environmental considerations ensures a comprehensive analysis, leading to an informed and optimal material selection decision.
