Innovative Outdoor-Ready Manual Coffee Grinder...using this as an example create one of a hair blow dryer

roblem Statement for a Manual Coffee Grinder

Hario Skerton Plus Ceramic Coffee Grinder is designed for coffee enthusiasts who value the freshness of

hand-ground beans, especially in outdoor settings like camping or hiking. While it is admired for its portable

size and manual operation, eliminating the need for electricity, the grinder has several design vulnerabilities

when it comes to outdoor utility.

Key components of Hario Skerton Plus are displayed in Figure 1, showcasing its current design. It features a

cylindrical body made from materials like ceramic for the burrs and a combination of steel and glass for the

rest of the structure. Despite these sturdy materials, the grinder’s construction presents issues during transport;

its components are sensitive to damage, and the grinding mechanism is prone to wear, resulting in reduced

reliability over time.

To ensure the grinder is up to the task of frequent use in various environments, the following design objectives

have been established:

- Design for Longevity (Priority: 5/5): Emphasise enhancing the grinder's resilience against the wearand-tear of outdoor activities.

- Design for Dematerialisation (Priority: 3/5): Aim to minimize the grinder's volume without sacrificing

its capacity.

- Design for Reliability (Priority: 3/5): The grinding mechanism should be overhauled to prevent loose

and rattling issues that suggest premature wear.

- Design for Aesthetic (Priority: 2/5): Enhance the visual appeal of the grinder to complement its

functional improvements.

These objectives are aimed at transforming Hario Skerton Plus into a more rugged and efficient tool for coffee

lovers on the go, ensuring that it stands up to the rigours of travel without compromising on the quality of the

grind. The redesign should be sympathetic to the grinder’s original aesthetic and operational principles while

introducing innovative solutions to enhance its sustainability and durability.

Portfolio Item 2 - Mind Map

Helps expand thoughts during the design process. It is a brainstorming session on paper that is used to visually

outline the design framework. It is generally created around a single objective (node) to which further

concepts/implications of your design are added around that. Each node on the mind map is one of the main

design objectives e.g. Design for Disassembly, Design for Longevity, Design for Reusability, Design for

Component #3:

Component #4: Ceramic

Ground Mechanism

Component #5: Ground

Coffee Reservoir

Component #1:

Component #2: Crank Arm

Component #7:

Component #6:

Dematerialisation, Design for Manufacturing, Design for assembly, aesthetic and further details or branches

around each node provide information about how to address that design objective. Note that the developed

mind map should clearly show the design considerations/directions for the whole product or main components

of the artefact with references to various features/parts of the artefact.

Tip for Mind Map Submission:

To ensure clarity and readability of your mind map, which is crucial for full comprehension and to secure all

possible marks, please adhere to the following guidelines:

• Mixed Page Sizes in a Single PDF: While your report should generally be formatted in A4 size, the page

containing your mind map could be set to A3 size within the same PDF document. Change the layout of

the page where your mind map is located to A3 size before you insert the mind map. Ensure that this A3

page is oriented in landscape format to maximise the use of space. This approach allows for a detailed

and expansive presentation of your mind map without compromising the continuity of your report.

• High-Quality Image: If you choose to submit an image of your mind map, ensure it is of high resolution

and clarity. Each element should be legible, and the overall presentation should be well-organised.

• Supplementary List: Alongside your mind map image, you are encouraged to provide a typed list of

ideas. This should be structured using headings and subheadings to reflect the hierarchy and connections

within your mind map. Refer to Sample Submission #2 for Portfolio item 2 in this guide for formatting.

Portfolio Item 3 - Concept Development and Visualization of Ideas

It requires a deep connection between your mind map (Item 2) and your concept sketches. It is essential to

create designs that are directly informed by your mind map's ideas. For each of your concept sketches, provide

a narrative that traces the journey from the mind map to the sketch. Explain how elements of your design were

conceived from the mind map and annotate these elements directly on your sketches. This will clarify your

thought process and demonstrate a strategic approach to design, showing that each feature has been carefully

considered and serves a purpose rooted in your initial brainstorming.

Your portfolio should feature a comprehensive suite of 2 to 4 concept sketches. These sketches are integral as

they transform your initial ideas from the mind map (Item 2) into tangible design propositions. Ensure each

concept sketch adheres to the following:

• Direct Correlation to Mind Map: Illustrate a clear trajectory from the mind map to each sketch. A

narrative should accompany every sketch, detailing the evolution of ideas from the mind map to the final

design features.

• Annotated Design Elements: Use concise and clear annotations on your sketches to spotlight the unique

aspects of each design. These annotations should clarify the function and rationale behind each feature,

guiding the viewer through your design process.

• Significant Design Variations: Display substantial differences between each concept sketch, such as

altering fundamental components or overall design structure, to showcase a breadth of innovative

solutions.

• Multiple Views for Clarity: Where necessary, present your ideas from multiple perspectives to fully

communicate the design. Similar to Fig. 3, provide different views (e.g., front, side, top) to ensure all

aspects of the concept are understood.

• Page Layout Adjustment: Modify the page layout for the concept sketches to an A3 format within your

A4 document if required. This modification is to accommodate detailed annotations and comprehensive

visuals, facilitating a clear presentation within the constraints of a single PDF file.

You have two options for creation and submission. You can either hand-draw your concepts on plain white

paper and scan them, or you can use digital tools. If you prefer digital creation, you may use a digital pen or

the drawing feature in programs like Microsoft Word, and then directly incorporate these into your portfolio.

Sample Submission for Portfolio item 3:

Fig. 3 shows Concept 1where the frame has been lowered to allow for flat packing since the seat, wheels and

steering wheel column can be removed. There has been some reduction in materials used. The wheels are

narrower, with a larger hollow wheel rim. A bumper and tow bar has been added. The car is longer, with an

adjustable seat to increase the longevity of the product.

Portfolio Item 4 - Evaluation of Design Alternatives

The Concept Analysis task provides an opportunity to practice analysis used to make conceptual design

decisions. With 2-4 feasible designs in hand, you need to evaluate the design concepts and choose the “best”

or preferred design. The advantage/s of each design concept should be clearly shown. Simple analysis can be

used with appropriate discussions to support the rationale of the chosen concept. However, to receive the full

mark for this task, it is expected that the concepts were compared to each other by using a weighted-decision

matrix or an equivalent tool with appropriate discussions to support the rationale of the chosen concept. The

word limit for this task is 500.

The major aspects of this task are:

- Systematically compare alternative concepts for fulfilling the design objectives as defined in task 1.

- Select the most promising concept for the artefact supported by evaluation of the alternative concepts.

Note: The weights of design criteria should be assumed based on the importance of each design objective as

you have prioritised them in Task 1.
