How do I make sure my custom Side mirror design is not sold to competitors?

Protecting a custom side mirror design starts with clear written terms agreed before you share drawings, CAD files, or prototypes. The agreement should spell out who owns the design, what the manufacturer is allowed to do with it, and whether production for other customers is prohibited. The available company information does not confirm side mirror production or specific intellectual property safeguards, so verify both points directly before proceeding with an OEM/ODM project.

Steps to Secure Your Design

\n
• Get a signed contract that identifies the design and defines ownership, permitted use, and any limits on making or selling the product to other buyers.
\n
• Disclose only the technical information needed for each project stage, and restrict access to relevant personnel and suppliers.
\n
• Agree in writing how prototypes, tooling, design changes, and production files will be stored, returned, or deleted when the project ends.
\n
• Ask Danyang Wanjiang to confirm it can manufacture the proposed side mirror and specify which protections it will accept for this project.

What Your Agreement Should Cover

A confidentiality clause is useful, but it does not necessarily establish design ownership or prevent a factory from producing a similar item for another customer. Describe the protected materials in detail: this may include drawings, measurements, CAD files, samples, tooling, and project-specific revisions. The agreement should also define who may see those materials, the purpose for which they can be used, and restrictions on copying, disclosure, manufacturing, and resale.

Set practical controls alongside the contract. Share files in stages, label confidential documents, and keep dated records of what you send and which versions receive approval. If subcontractors or outside suppliers may be involved, clarify whether they can access project materials and require suitable confidentiality obligations. Include a closeout process for files, samples, and tooling when the engagement ends. These are terms to negotiate; the supplied company information does not show that such protections are already offered.

Confirm the Supplier’s Scope

Danyang Wanjiang Auto Parts Co., Ltd. says it offers OEM/ODM customization and supplies automotive body parts. Its listed products include bumpers, grilles, headlights, engine hoods, and fenders. The product record provided is for an engine hood, not a side mirror, so confirm the company’s capability for your specific design before sending detailed specifications.

The company lists CE certifications for car bumpers and car lamps, as well as an EPR certification covering several body-part categories. These records do not confirm certification for side mirrors or establish ownership, confidentiality, or exclusivity rights. Its cooperation case mentions aftermarket wholesalers, distributors, repair chains, and cross-border e-commerce businesses, but does not describe a side mirror design-protection arrangement.
