Design Situation (GIVEN)

In the EcoBreeze Fusion challenge, craft the ultimate DIY portable handheld fan, seamlessly merging technology, individuality, and environmental consciousness. Your mission is to design a fan that not only delivers a refreshing breeze but is a personalized statement of innovation and sustainability. Unleash your creativity, explore eco-friendly materials, and showcase the future of cool in a single handheld device. The challenge is not just to stay cool – it's to be cool, uniquely and environmentally conscious.

Design Brief (GIVEN)

Design and make the ultimate DIY portable handheld fan, fusing technology, individuality, and environmental consciousness.

*FUN FACT*

After identifying a design opportunity, you need to write the design brief.

A design brief is a clear statement of the design task and its requirements.

Act 3. 1 Design Considerations

Design Considerations	Questions?	Response
Functions	What are some other functions i want for my portable fan? In what ways can I use my portable fan? Where are some locations i can place my portable fan?
Aesthetics	What are some interesting designs and shapes I can shape borrow for my portable fan?
Ergonomics	What are some of the ergonomics factors I need to consider to ensure comfort, usability, and efficiency when using my portable fan?
Anthropometry	What are some of the human measurements I need to consider in the design of my portable fan?

Act 3. 1 Design Specifications

Design Consideration	Design Specifications	Evidence
Functions
Aesthetics
Ergonomics
Anthropometry

*FUN FACT*

A design specification is a more detailed listing of the requirements, setting out exactly what the product must do and the limits within which it should be designed.

Act 3.4 Research on 3 Existing Portable Fans for inspiration (SAMPLES)

*FUN FACT*

Sources of research

Primary research will yield information that comes directly from experimentation or contribution from other people through discussions and surveys.

•Information that is extracted from existing publications or databases is called secondary research.
