HALLO, I AM CHI-CHEN CHANG. short for 7J.
Look forward to Discovering, Never stop Tr ying, Love Designing!
About 7J, "Design for humans, for well-beings, for future."
Be open-minded as nothing remains the same. I found learning new thing s is a key to upgrading your way of thinking & working as well. Therefore, I enjoy self-learning par ts in every project very much.
As designers, we should design products based on a flow of human awareness in society, and we should make use of resouces, materials, structures to make a chang and an impact to our world!

"A new way of holding phone, A different experience of believing the case again."
Junior Independent Project Mobile accessory 3 months
Feel safe to possess mobile phone, but it is hard to hold tight. THE MORE WE RELY on mobile phone, THE MORE SAFTY CONCERN we care. No one can live comfortablely without cell phone, its existence has become more irreplaceable.
How can we balance function and visual satisfaction ?
Ideation Focus on more steady method to make mobile safe physically and mentally.

You need to have a 24.3Ă—11.8cm palm at least to operate cellphone with sigle hand.
FINDING SOLUTIONS
Due to the length limit of hands, phone-drop happens when people are holding phones but adjusting volume at the same time. And pressing the opposite button is also sometimes a blame of.

Recreate the relationship between phone case and hand gestures.
Define Shape and Mechanisim Make use of material to shape, borrow the idea from existing product.
M O U N TA I N S H A P E To mimic organic shape, I used oil-soil to outline. Based on model form, then I created a 3D model in Solidworks. It nearly took me five days to analyze section profiles and solve modeling problems.
ROLL MECHANISIUM The main structure applied with rolling motion is to simulate the workflow in mouse control.
Only took the rotating parts from mouse, I eliminated the electrical parts, then left space for mechnisium.

Senior Group Project / Industry-academia cooperation with EUPA HIGH SPEED BLENDER 3 months
Lean Product Development Lean Product Development is based on series of practical method for companies to rapidly understand the unsatisfied needs, which could help them to reduce neddless cost and shorten the product cycle period. A well-developed product improves the quality of human lives, in order to achieve that, it is challenging to precisely identify customer core values and offer a thoughtful solutions.
Development Process
Identifying user value Competitor analysis Discover trade-off points Hypothesis and testimony experiments Modeling and assembly
INDENTIFYING USER VALUE Interview Process
We found eight users to interview, most of them were housewives. We required them to make familiar dishes with their own High Speed Blenders.
STRATEGY
Thinking aloud test
All users were asked to speak out their thoughts in mind and steps while operating blenders; we stay silently beside them observing their behaviors.

The noise f rom High Speed Blender is an serious pain spot SHORT/LOW

HYPOTHESIS AND TESTIMONY EXPERIMENTS Noise Happens when...?
The shrillness in high-pitched noise happens under the mode for food break-up.
High speed scary motor
Test volume of motor independently.
Test how to get the lowerest noise combination.
Reduction f rom Source Though motor-independently noise test, there showed the best noise reduction when seperating the attatched fan blade; therefore, we tried to search a more effective way of heat release by designing the arrangement between motor and fan.

COLD AIR
Experiment showed that original order is the least eff icient on releasing heat, and even cause loud noise. Hot air and cold air from outside would generate tubulent flow, which create more noise.
In Lean Product Development, it is crucial to conduct quick and low-cost experiment to ensure the decisions were correct and verify the hypothesis for improved functionality. Therefore, we used simple way such as cardboard to simulate the studs and walls within architectural structure.

Experiment Method : Applied 3 different slopes to see the sizes of bubbles after operating with max speed. Use flour-water mix to simulate food mixture.
TEST RESAULT : We can see that 0° trough cup created more bubbles than 30° and 60° one, but there wasn't any big difference for the two.
Particle Retain Blade Diversity
Experiment Method : Applied 20mm, 10mm, 5mm clay ball with different blade to see the particle is broken up or not.
TEST RESAULT : Clay balls had not been fully broken-up by wider side of the blade, which means we can use reverse direction to retain some particles for a better taste.
