Research, design and
commercial judgment.
As a product design studio in Hong Kong, we combine customer research with hands-on manufacturing experience. We also bring commercial judgment from building product businesses.
Industrial design studio: find the right product
First, understand where a product fits into everyday life. For example, consumer interviews and prototype testing informed the d.light S1 solar light. Ti then led the final product design while working in-house at d.light.
Product design studio: connect product and interface
Next, consider who makes decisions around a product. For example, AQUA IQ brings water-leak protection into a compact product with controls for installers and homeowners. Because both groups depend on the same system, product form and interface design need to work together.
Make production part of the design
Finally, develop the product around how it will be made and used. Lumina ONE, for example, integrates functions into three main parts to simplify assembly. Its architecture also considers use, repair and material separation. In contrast, Treecup shows another approach: a reusable cup range with adaptable branding and a bio-based material.
