Designed a new refrigerator more accessible for people on wheelchairs (2020,  aged 16)

• The bottom of the refrigerator is recessed inward to allow wheelchair users to get closer.

• Items like frequently used bottles or beverages are placed upright in the lower part of the refrigerator for easy retrieval while sitting.

• When the refrigerator door is opened by a voice command, the shelf inside the refrigerator automatically slides out towards the user like a drawer, making it easy to retrieve items even while seated.

An Idea for troubleshooting inter-floor noise from musical instruments (2019, aged 15)

• Invention Abstract: To prevent inter-floor noise by measuring the loudness of musical instruments according to the time and space of musical instrument playing and notifying when the sound is loud.

• Target Problem: Musical instruments are often the cause of noise disputes between apartment residents. However, instrumentalists may not realize that they are playing louder when they are immersed in their performance.  Noise measurement apps are available on smartphones, but noise generators have no reason to use them often.

• Solution invented: The present invention adds a function to metronomes and guitar tuners, devices frequently used by instrumentalists, to warn them when their playing becomes too loud so that instrumentalists can naturally manage the sound of their playing.  (details omitted)
