A safe solution for defending against mosquitoes by harnessing the power of air
A safer solution for defending against mosquitoes outdoors
Mosquitoes can be eliminated by swinging the device on target like a conventional zapper racket. However, it is considerably safer as it does not employ high voltages across exposed meshes.
Physics is the enemy of mosquitoes
Air expelled by a fast-spinning impeller attracts mosquitoes to the target surface through the Coanda effect. The device’s aerodynamics has been tested through numerous iterations of computational fluid dynamics (CFD) and physical prototyping.
Appotek - Intelligent pill dispenser
Appotek is an IoT-connected pill dispenser that tracks and streamlines the managing, taking, and restocking processes of medications. It features a water dispenser, audio reminders, and fingerprint-secured inventory access.
Cranky ball thrower
In this purely mechanical squash ball launcher, the ball is propelled by the fast-spinning rubber-padded flywheels which are driven by a crank through a 1:29 ratio compound gear train.
3D-printed garment steamer wall mount
A 3D-printed wall mount for a handheld garment steamer that includes a cable tidy. The Voronoi structure was generated in Grasshopper 3D.

With a focus on safety, this portable device enables outdoor goers to actively eliminate attacking mosquitoes without employing chemicals and high voltages. When targeted, mosquitoes are guided by the generated airflow into a sticky collection chamber, which can be ejected to clean out the captured insects.
As somewhat of a hybrid between an industrial designer and design engineer, Hoyin strives to create beautiful forms and is guided by his curiosity in intricate mechanisms. With experience in designing and CAD modelling complex surfaces and production-ready parts, he is confident to take on projects that are aesthetically-focused or technical in nature. Hoyin is always eager to develop new skills in a team to advance their creative endeavours.
