Product design services
Co-developing new products with you: industrial and appearance design, and function and user experience design with PCB.

What we offer
A new product succeeds when how it looks and how it works are designed together. JIN INTER partners with customers to develop new water and home appliance products, through two groups of design services: industrial design and product appearance, and function and user experience (UX) design, including the PCB that delivers it.
Service 1
Industrial design and product appearance

Example: concept sketches of a water appliance.
JIN INTER provides industrial design and product appearance design with its own in-house design team, and with leading product design companies in Korea that we have a good working relationship with. Depending on the project, we assemble the right team for your product, from a refreshed look for an existing model to the appearance of an all-new product.
Concept ideation
Brainstorming and rapid 2D / 3D sketching to explore how a new product looks, works and feels.
Form, colour and finish
Shape, colour, material and graphics chosen to suit your brand and your target market.
Usability and ergonomics
Human factors checked early, with sketches and study models, so the product is comfortable to use.
3D models and renderings
Computer-aided 3D models and photo-realistic renderings to review the final appearance before tooling.
Design for manufacturing
Volume, cost and manufacturing method are considered from the start, so the design can be produced.
Brand identity
A product look that is consistent with your brand identity across a product range.
Service 2
Function and user experience (UX) design
Our team has long experience in R&D of water purifiers and household appliances. We apply it to the functions and the user experience of your new product, develop new display and control features on the PCB, and supply high-quality PCBs from Korea to put them into production.
Function definition
We define which functions your new product needs, starting from how people will use it.
User experience (UX) design
How the user operates the product: display, buttons, indicators, icons and the flow between them.
New display and control features
We develop new display and control features on the PCB, to match the experience we design.
High-quality PCBs from Korea
We supply high-quality PCBs made in Korea, built to your functions and your quality requirements.
Water appliance know-how
Our team has R&D experience in water purifiers and home appliances, including water quality display, filter exchange and cleaning functions.
Testing and validation
PCB samples are tested with your product, so the functions work as designed before production.

Example: display and touch interface of a water appliance.
