End-to-end
product development
We handle the entire journey — from first sketch to mass production.
Our NPI process
At OPD, we guide products from concept to mass production using a structured NPI methodology.
Instead of treating design, engineering, prototyping, and manufacturing as separate tasks, we integrate them into one streamlined process. As a result, we reduce risk, improve manufacturability, and shorten time-to-market.
Moreover, by factoring in production requirements from day one, our team helps you turn ideas into launch-ready products — faster and with far greater confidence.
What is NPI Process
Proof of concept
We turn ideas into clear, actionable product directions.
First, we conduct user research, market analysis, and a technical feasibility review. Then, we define the product positioning, functional scope, and development roadmap. In short, this phase answers one question: is the product worth building — and how do we build it?
Involved Service Modules:
Engineering validation test
We transform the validated concept into a working product prototype.
Building on the POC results, our team develops the industrial design, mechanical structure, electronics, and software in parallel. Next, we produce functional prototypes to test core features, system stability, and user experience. This step also surfaces key technical risks — so we can address them early, before tooling begins.
Involved Service Modules:
Design validation test
We fine-tune every subsystem and confirm the product is production-ready.
At this stage, we optimize the mechanical structure, electronic hardware, and software together — not in isolation. Meanwhile, we run reliability tests and stability checks across all operating conditions. As a result, the product meets every requirement for function, performance, and manufacturability before we move forward.
Involved Service Modules:
Production validation test
We verify the full assembly line and prepare for mass production.
Now we run small-batch trial production to validate the complete assembly process — including PCB mounting, system integration, and firmware flashing. At the same time, we set up quality-control checkpoints and finalize packaging, labeling, and branding materials. In other words, everything the factory needs is locked in before volume production starts.
Involved Service Modules:
Mass production
We scale up production and keep optimizing based on real-world feedback.
We manage the transition from trial runs to full-scale manufacturing. Throughout this phase, we monitor quality metrics, coordinate with suppliers, and roll out software updates as needed. Moreover, we continuously incorporate market feedback — so the product keeps improving long after the first unit ships.

NPI development capabilities
Featured projects
Smart Comb
A smart scalp-care comb with a built-in misting system. We designed the ergonomic grip, fluid reservoir, and outer shell for everyday comfort and salon-grade performance.
Anti-Choking Device
A home-use Heimlich maneuver device developed based on the principles of the Heimlich maneuver.
Anti-hair loss shampoo
A complete brand and packaging system for SLEK Group's anti-hair-loss shampoo line. We delivered bottle design, visual identity, and retail-ready packaging in one integrated project.
Self-Service Checkout System
Core terminals for the unmanned retail environment. We designed the hardware enclosure, user interface layout, and scanner integration to speed up checkout and reduce queue times.
leaPower
A consumer battery brand built around the idea of portable energy for everyday life. We created the brand name, logo, packaging system, and product-line visual identity.
Sci-fi style electric ceramic stove
A spaceship-inspired electric ceramic stove that brings a modern, futuristic aesthetic to the kitchen. We designed the outer shell, control panel, and heat-dissipation structure.
Children's KTV
A kids' karaoke system that combines singing, learning games, and parental controls in one friendly enclosure. We designed the hardware, UI, and playful industrial form factor.
AI interactive terminal
An AI-powered terminal that identifies NFC chips and plays IP-specific audio content — enabling personalized, one-tap interactions. We handled the industrial design, software integration, and user flow.
From consumer electronics startups to Fortune 500 companies, we have partnered with over 100 clients across industries including personal care, home appliances, retail technology, and education. What they have in common: a need for a single team that can take a product from rough idea to shipped units — without handoff gaps or communication delays.
