Here’s a clear, step-by-step product development process from my perspective as expert of Mersain Innovation – designed for clients new to hardware creation, for your reference only:

1. Concept & Feasibility Study (2–4 Weeks)
Goal: Align on your vision and technical reality.
Tasks: Market research, rough sketches, basic technical analysis.
Deliverables: Mood boards, feasibility report, target cost/BOM estimate.
"We ensure your idea is both innovative and manufacturable."

2. Industrial Design (ID) (3–6 Weeks)
Goal: Transform your idea into an ergonomic, user-friendly form.
Tasks: 2D/3D styling, color/material studies, user experience mapping.
Deliverables: 3D renderings, physical appearance model, CMF (Color/Material/Finish) report.
"You’ll see and feel your product before engineering begins."

3. Mechanical Engineering (4–6 Weeks)
Goal: Make the design functional and durable.
Tasks: 3D CAD modeling, material selection, mechanism design, DFM/DFA analysis.
Deliverables: Engineering drawings (GD&T), 3D STEP files, FEA simulation reports.
"We engineer every part for easy assembly and low-cost production."

4. Electronics & Firmware (6–12 Weeks)
Goal: Build the "brains" and functionality.
Tasks: Circuit Design: Select sensors, motors, chips.
PCB Layout: Design circuit board layers/routing.
Firmware: Write code for controls/logic (e.g., motor timing).
Deliverables: Circuit schematics, PCB Gerber files, firmware source code.
"We handle complex electronics so you get plug-and-play intelligence."

5. Prototyping (2–4 Weeks)
Goal: Test real-world performance.
Tasks: 3D-printed/custom parts assembly, basic functional tests.
Deliverables: Working prototype units, test video, improvement plan.
"Touch and test a real version – no more guessing."

6. Debug, Test, Certify (4–8 Weeks)
Goal: Refine reliability and pass safety standards.
Tasks: Fix hardware/software bugs.
Stress-test components (e.g., 50,000 motor cycles).
Pre-certify for UL/CE/FCC.
Deliverables: Test reports, certification roadmap, refined prototypes.
"We break it so your customers won’t."

7. Manufacturing Ramp-Up (8–12 Weeks)
Goal: Seamlessly transition to mass production.
Tasks: Tooling (molds, jigs) creation.
Pilot runs (EVT/DVT/PVT) with factory.
Quality control system setup.
Deliverables: Golden samples, assembly SOPs, QC checklists, ready-to-order status.
"We deliver turnkey production – you receive shipment-ready goods."

Total development time: ~6–12 months (flexible for complexity).
We manage the tech – you focus on your brand and customers.
Let’s build something great together!
