Design Background

1. Professional musician

2. Want to promote Taiwanese traditional music

3. Try to blend traditional instruments into modern music

Moon Guitar is one of the unique traditional musical instruments in Taiwan. It used to be seen everywhere, but now it has gradually declined because it can not keep up with the changes of the times. People are united and great because of their culture. Only by understanding our own culture can we truly understand ourselves and promote ourselves without forgetting our roots.

Goal

-Increase the visibility of Moon Guitar

-Awaken local awareness

-Revive traditional culture

The temperaments between East and West are different.

When playing with western instruments, it is often stuggle to express the characteristics of the Taiwan instrument.

“Revolution of Traditional Moon Guitar

Under the impact of various foreign music, our traditional music is gradually lost. In order to prevent it from being lost, we need to find a way to bring Moon Guitar back to the eyes of the public.

1 Can perform Moon Guitar features with modern bands.

2 More convenient to cooperate with western instruments.

3 Attract attention of young people and keep traditional instruments alive.

- Ehance the charm of the stage

Development

Before starting the design, we decided to think about various possibilities divergently, and use the mind map as a divergent tool to really analyze the points that need to be considered when redesigning a new Moon Guitar.

The picture above is an interview with the teacher of the Taiwan Smile Folksong Group.

We understand that the Moon Guitar had been a popular instrument in Taiwan, but it has gradually declined due to the impact of contemporary foreign culture and the suppression of policies in the early government of Taiwan.

Design Concept

Developed play action with strong stage effect and shape with oriental imagery.

In order to attract the attention of the public, we must have novel shapes and distinctive stage charms, but at the same time we do not want to lose the traditional charm of Moon Guitar.

Remove the strings

Attract the audience

Modeling test

Change the temperaments

Taking the crescent moon as the main axis element as the focus of the stage charm.

In addition to retaining the shape of the traditional Moon Guitar, we also create with oriental elements as the main axis.

Intended to use plastic and silicone to create a light and novel style and make pressure sensing more sensitive

Intergrated temperament and Emphazied traditional fingerstyle

The shape of the crescent moon will gradually light up as the mode is switched, adding a little flavor to

Userbility Test

After digitization, we can freely convert the 6 eastern scales into the western 12 scales, and remove the strings and replace them with pressure-sensing buttons and micro-switch wave plates.

Developed more type of traditional Taiwanese musical instruments to build a performance system

Through the usability test with moon guitar teachers, they consider that the function not only meets the needs, but also expands the form of performance. Teachers also look forward to redesigning more instruments to create a complete performance systemental image.

Through arduino to achieve electronic and combined with UI interface, integrate and develop a set of apps to allow musicians to input the desired tone on the mobile phone in advance, and only need to easily rotate the handle on the stage to quickly change it.

Through arduino programming combined with midi music, the experts recorded the basic sound and adjusted it by the music producer and converted it into midi music for playing.

Redefine the style of outdoor camping

'' tentagon'' is a two-person lightweight tent with an inflatable frame, mainly for beginners in camping. Compared with the inflatable tents on the market, tentagon is lighter and more technical. It adopts innovative three-axis air column technology, which subverts the previous one-axis technology on the market, so that the overall tent frame has a better supporting structure. It is also made of environmentally friendly fabrics.

Better Class

Teach for the better tomorrow

Better Class is a teaching aid that combines software and hardware. It uses full-seat projection technology to transform complex abstract concepts or 2D planes into simple, intuitive and easy-to-understand 3D three-dimensional shapes. The current trend of smart digital aids in class allows teachers to have more diverse teaching methods and enhances students' lack of spatial cognition. After investigation, it is found that although spatial cognition is not specifically listed as a course, it is widely used in Among them, we designed Better Class in order to allow students to better understand and enhance students' interest in class.

Design Background User Analysis Interview

According to the interview results, children in grades 5 and 6 may use abstract concepts or problems involving space in their classes, such as nature classes, mathematics classes, etc., and children will find it difficult to understand only through 2D pictures content. And according to the above chart, it is known that students have extreme differences in spatial cognition during this critical period.

Enhance students' spatial cognition

Every time I encounter abstract and difficult problems in class, 2D pictures may not make me understand, and the teacher's courses will always make me unable to get excited.

Pain point

1.class is boring.

2.Can't understand abstract questions.

3.2D graphics are sometimes more confusing.

Needs and Target

Create a new teaching mode

New ways of teaching and better ways to answer the questions I do not understand.

Although there are teaching materials provided by the manufacturer, it is very troublesome to prepare. Sometimes the students' questions are difficult to use words to make the younger students understand.

Pain point

1.Teaching materials are limited but it takes too much time to prepare by yourself.

2.Individual differences among students gradually emerge.

Needs and Target

I need new teaching aids that don’t take too much time to prepare so that I have more choices in teaching and help students better.

Problem Define

It is found that portability is not the key point and it is not cost-effective to need too many institutions to achieve.

Human factors need to be reconsidered to define product size.

The interface functions are too complex and should be more linear.

The key point is to synchronize the screens of the tablet and the projector, and let the teacher arrange the timing for the children to interact. With the simple and intuitive tablet interface, the children can easily control the 3D projection through the handle, so as to achieve active exploration and The purpose of multi-angle learning.

Modular Outdoor Wedding Banquet Chair

Design Background

Investigating the layout of Taiwanese weddings in the market today, from the perspective of the industry, the services provided are too similar and the competition is fierce. From the perspective of the guests, there are too few choices or the styles are polarized.

Design Goal

Enhance the texture of the wedding

Make good use of modularization

Designed for both business and customers

As a wedding banquet business owner, I will contract a lot of fabric content. How to provide customers with diverse choices to attract consumption while saving unnecessary expenses and costs has always been my goal.

Pain points

Needs and Target Persona

“Modularization to meet various needs”

Because there are no chairs specially designed for setting, no specificity leads to fierce competition.

Good-looking chairs always sacrifice flat design for styling, which leads to higher shipping costs.

If you want to meet the needs of customers, you need a variety of tables and chairs, but usually these tables and chairs do not have a flat design, which leads to increased transportation costs.As a business owner, we want to provide customers with a more complete experience and at the same time try our best to reduce costs.

Design Concept

First think about various possibilities divergently, then find the direction from them, and then search the image board from the selected direction to have more specific elements that can be taken and gradually optimized.

The variability is good

But the shape does not match The shape is a bit smoother Integrate reference elements better

Design Description

Sort and stack chair backs and chair bodies

Upside down to choose a style After choosing a style , just assemble it

The flat design makes it different from traditional outdoor wooden chairs. It can be dismantled and disassembled, greatly reducing transportation costs and handling labor.

Decorate him with cloth as you like

Using a specially designed mechanism to allow the back of the armrest to be loosened and turned over greatly reduces the difficulty of operation and also increases the result of its multiple properties when synchronizing time.

The chair back that can be turned over and has multiple empty spaces allows people to choose the atmosphere they want according to the situation and it is easier to use cloth to decorate.

Foode

Make meals both beautiful and delicious

With the popularity of social networks, the public began to love to share various things on social platforms, most of which are food. In addition to the basic recipes and steps, we found that the final presentation effect has become the most important part of people today. In addition to adding the design teaching of the plate, it also makes their choices more free and changeable. Instead of succumbing to rigid rules, recipes pay more attention. The final visual presentation effect is used to make choices, and various filters are provided at the end. In addition, a platform function has been added to allow users to share their favorite works and communicate with each other.
