At the point of finishing this project, I would like to express my sincere thanks to all those who have lent hands for me.

First of all, I would like to take this opportunity to show the sincere gratitude to Dr.Xu Sun and Dr.Bingjian Liu, who have tried their best to support students engaging in such an exciting project. They provided great help in the darkest time at the end of the semester. I would also like to express my sincere appreciation for Mr.Luis Moreno Leyva who inspired me to explore deep into the meaning of the design which leads me to a higher level of products semantics and social values. These experiences will definitely be the most unforgettable memories I have been through.

Secondly, I’d like to express my gratitude to my roommates who always listen to the childish design ideas during the semester despite of how silly those thoughts were. Without your guidance, I could never imagine I can push this project into this new level.

Last but not the least, I would like to thank those industrial consultants, classmates and technicians. Thank you for your most generous supports which leads me to the final.



The design starts from the attempt to redesign the current medical device market for kids with asthma symptoms.
It follows an innovative solution to eliminating the traditional semantics associated with inhaler but enhancing the importance of communication with the acceptance for inhaler design for children.

Combing with the app to record and monitoring the peak flow data, this design forms a holistic view of monitoring and the conditions for pre school age children with asthma symptoms.
