I am developing a new spectacle frame and need a product designer who can balance engineering accuracy with eye-catching style. Both the mechanical function and the overall look carry equal weight for this project, so I’m counting on you to finesse every detail—from hinge geometry to surface curves—until the piece is production-ready and commercially appealing. READ BELOW- DESIGN WILL BE OF 2 PARTS - 1 FRAME - THIS ALLOWS LENS TO BE LOCKED INTO IT WITH HANDS 2- LENS FRAME - USED TO FIX LENS IN IT AND THEN IT GOES INTO THE FRAME TO BE LOCKED. THERE NEEDS TO BE A SEMI PERMANENT LOCKING MECHANISM. Key design parameters • Material: the frame will be injection-moulded in PC or TR90. Every feature must respect the flow, draft and wall-thickness constraints typical of these plastics. • Primary objective: robust mechanical performance. The temple mechanism, lens retention groove and nose-bridge stress points must all be proven durable while keeping the frame lightweight and comfortable. Deliverables • Full 3D CAD model (SolidWorks, Inventor or comparable) ready for tool-maker hand-off • 2D manufacturing drawings with tolerances, draft angles and material call-outs • Exploded views or animation highlighting hinge action and lens insertion • Renderings that clearly communicate colour, finish and brand language Acceptance criteria 1. All contact points survive a virtual drop test and meet standard eyewear flex tolerances. 2. Draft analysis shows zero under-cuts or gating conflicts for single-shot moulding in PC/TR90. 3. Aesthetic proposal matches contemporary lifestyle eyewear trends while keeping SKU cost competitive. If you have a track record in eyewear, consumer electronics casings or similar injection-moulded products, I’d love to see examples and discuss how you would approach this frame in detail.

Hello, I can design your injection-molded spectacle frame system (frame + lens frame) with a semi-permanent locking mechanism, ensuring durability, comfort, and clean aesthetics. Deliverables: • 3D CAD (SolidWorks/STEP) ready for tooling • 2D drawings with tolerances, drafts, material specs • Exploded view/animation (hinge + lens locking) • High-quality renders Design will follow PC/TR90 DFM rules (draft, wall thickness, no undercuts). Do you prefer a snap-lock or cam-lock mechanism for lens retention? Portfolio: https://www.freelancer.com/u/mayank0752 Best regards, Mayank

I propose developing your spectacle frame as a precision-engineered, modular eyewear system that merges industrial-grade mechanical reliability with modern lifestyle aesthetics. The design will focus equally on structural integrity, manufacturability, and visual identity, ensuring it is both production-ready and commercially competitive. This project will be approached as a functional product system rather than a simple frame design, ensuring your eyewear concept is both mechanically robust and visually distinctive in a competitive market. I would be glad to begin with initial concept sketches and locking mechanism prototypes before moving into full CAD development.

Hello, Thank you for sharing the project details. The spectacle frame design is interesting because it requires both a strong mechanical solution and a clean, modern appearance. I can work on this in SolidWorks and develop a practical design focused on: * a 2-part frame system, * a semi-permanent locking mechanism for the lens frame, * proper draft and wall thickness considerations for PC / TR90 injection molding, * strong and comfortable hinge / nose-bridge geometry, * and a visually appealing result ready for presentation and manufacturing review. My proposal is: * Full 3D CAD model in SolidWorks * Exploded view or simple assembly animation * Basic manufacturing drawings with tolerances and material callouts * Renderings to support the concept and brand look I work carefully to keep the design functional, manufacturable, and attractive, while maintaining clear communication throughout the process. Best regards.

I will engineer your two-part spectacle frame to ensure a perfect balance between mechanical locking precision and contemporary styling. I specialize in designing for PC and TR90 injection moulding, and I will develop a robust, semi-permanent snap-fit mechanism that allows for secure lens-frame integration while maintaining sleek surface curves. My process includes detailed draft and wall-thickness analysis to ensure the design is optimized for single-shot tooling without undercuts or gating conflicts. I will deliver a complete SolidWorks/Inventor CAD package, including 2D technical drawings with precise tolerances and high-resolution renders for your brand presentation. I will also provide exploded views to demonstrate the assembly and hinge geometry, ensuring the frame meets eyewear flex tolerances and drop-test durability. I am ready to apply my experience in precision plastic components to make this frame production-ready. Thanks, Muhammad Mohid Ahmed
