G-Spot RX: Adult Product Design and Engineering
Start a project

Published August 10, 2026
Adult product design is a mechatronics problem: a patented motion mechanism, PCB programming, body-safe silicone overmolding, and a prototype convincing enough to fund a crowdfunding campaign — all inside a three-month window.
For G-Spot RX our mechanical and electrical engineers collaborated on 3D printing, PCB programming, and silicone rubber molding to deliver a working prototype of a patented motion unlike anything in the category. The Indiegogo campaign raised over $50,000, major retailers took notice, and the product is selling today.

Product development at a glance
| Scope | Ergonomics, industrial design, CAD, prototyping, DFM |
|---|---|
| Considerations | Body-safe materials, cleanability, sealed assembly, discreet packaging |
| Deliverables | Production CAD, prototypes, molding package, packaging |
| Typical timeline | 6-12 months |
Confidential categories still need rigorous engineering
Personal products carry the same requirements as any regulated consumer good: materials that are safe in prolonged skin contact, seams that can be cleaned, and assemblies that stay sealed. Add discretion in packaging and shipping, and the design constraints are tighter than most housewares.
How we handled the project
Work was run under confidentiality from the first meeting. We developed the form around ergonomic use, specified medical-grade silicone and compatible substrates, and detailed parts for sealed molded assembly with no crevices that trap residue. Packaging was designed to be plain in transit and branded only inside.
Frequently asked questions
Do you sign NDAs?
Always. Confidentiality is standard on every project, and sensitive categories can be kept off our public portfolio entirely.
Which materials are appropriate?
Platinum-cure silicone and compatible rigid substrates, chosen for skin contact and cleaning cycles.
Can you source manufacturers for this category?
Yes. We coordinate with factories experienced in body-safe molded products and review first articles.
Capabilities used on this project
Rapid prototyping services
3D printing, CNC machining, urethane casting and functional prototype builds with published materials, tolerances and lead times.
Electronic design and PCB engineering
Schematic capture, PCB layout, firmware and electromechanical integration for connected hardware.
Design for manufacturing
Molding-ready geometry, tolerances, production drawings, assembly documentation and DFM review with the tooling vendor.
The adult product development playbook
A patented motion, not another shape
Category products differ by color and contour. Gene Allen's patent covered a motion distinctly similar to the human touch — which meant the engineering, not the styling, was the product.
Mechanical and electrical in the same room
The motion mechanism and the PCB programming had to be developed together. Our engineers worked as one team, contributing design improvements beyond the original brief.
Silicone molding for body-safe production
Silicone rubber molding techniques produced parts suitable for the category's material expectations while carrying the internal mechanism — texture, safety, and mechanics in one part.
Prototype to crowdfunding in under three months
The full prototyping cycle ran in fewer than three months. The working prototype exhibited at a trade show, earned industry press, and anchored an Indiegogo campaign that raised over $50,000 — well past its goal.
| Challenge | Approach | Outcome |
|---|---|---|
| Novel motion | Patented mechanism developed by combined ME/EE team | Category-distinct function, not just form |
| Body-safe materials | Silicone rubber molding | Production-appropriate surfaces |
| Electronics | In-house PCB programming | Motion control integrated with mechanism |
| Funding | Trade-show-ready working prototype | Over $50K raised on Indiegogo, plus retail and press attention |

Talk to an engineerHow much does sex toy design and prototyping cost?
A mechatronic adult product of this class typically runs $15,000 to $50,000 through working prototypes, depending on mechanism complexity and electronics scope.
How long does it take to prototype an adult product?
G-Spot RX went from brief to working prototypes in fewer than three months, including 3D printing, PCB programming, and silicone molding.
Is discretion part of the service?
Yes. Adult product projects are handled under NDA like everything else we do, and the category is treated with the same engineering rigor as any medical or consumer device.
Do I need a patent before starting?
It helps. G-Spot RX's patented motion defined the engineering target. We can also help you reach patent-pending status before detailed development begins.
