Electric Kettle Prototype (Pre-Mold Validation) for Design, Ergonomics, and Manufacturing Readiness

More Details

Why This Prototype Was Needed

Before investing in expensive tooling, the client needed a full-scale physical prototype to validate:

• Overall form and visual proportions
• Ergonomics of the handle (grip, comfort, safety)
• Structural layout and interference check
• Feasibility of soft-touch overmolding areas

👉 At this stage, mistakes are cheap to fix.
After tooling, they become expensive.

Core Engineering Questions

1. Ergonomics vs Heat Safety
   • Handle must be comfortable
   • But also:
     👉 Must isolate heat during boiling
2. Soft-touch Design vs Manufacturability
   • Rubberized grip improves user experience
   • But:
     👉 Adds complexity in overmolding or secondary processes
3. Integrated Structure vs Internal Layout
   • Compact design
     👉 Requires precise internal space allocation (heating system / wiring / insulation)
4. Appearance Intent vs Process Reality
   • Design shows clean matte finish
     👉 But actual production may differ depending on molding & coating

Why These Processes Were Used

• 3D Printing (SLA/SLS)
  • Fast geometry validation
  • Complex structure realization
  • Ideal for early-stage iteration
• Vacuum Casting
  • Small batch duplication
  • Better surface consistency than raw prints
  • Closer to production material feel
• Soft-touch Simulation (TPU / Silicone)
  • Mimics overmolded grip
  • Enables real ergonomic testing

👉 Result: A near-production-like prototype without tooling investment.

FAQs

Q1: Is this prototype functional for heating?
No. This stage focuses on structure and design validation, not full heating performance.

Q2: Can you simulate rubber overmolding?
Yes. We use TPU or silicone to replicate soft-touch areas.

Q3: How close is this to final production?
Visually and structurally close, but not identical to injection-molded parts.

Q4: Can this be used for client presentations?
Yes. These prototypes are often used for investor demos and approvals.

Q5: What’s the next step after this prototype?
DFM optimization → tooling → injection molding → pilot production.
