Industrial Design / Mechanical Engineering RFQ – Clamshell Gaming Handheld I'm looking for a mechanical designer/product engineer to assist with the design of a clamshell handheld gaming device. There is no need to do any software development or PCB electrical design for this project. Scope of Work Mechanical Housing Design [login to view URL] * Design and refine the top and bottom housing assemblies that already exist in [login to view URL] * Create manufacturable 3D CAD models suitable for prototyping and eventual production, ideally on a CNC machine for prototyping * Consider assembly, serviceability, and manufacturing constraints throughout the design. Display Integration * Integrate a 4.16" 1920×1080 LCD display into the bottom housing using supplied display datasheets. * Integrate a 6.0" 1920×1080 OLED display into the top housing using supplied display datasheets. * Design mounting features, retention methods, cable routing, and display protection. Hinge Design * Integrate an existing hinge solution (currently based on Nintendo 3DS XL hinges) or propose an improved alternative to open and close the top display * Ensure adequate opening angles, durability, cable routing, and user experience - either by suggesting the use of a flex cable (design required) or some alternative cable, such as an off the shelf eDP cable Controls * Integrate: * Analog trigger mechanisms with spring return. * Digital shoulder buttons. * Face buttons (A/B/X/Y). * D-pad. * Start/Select/Home buttons as required. * Preference for off-the-shelf button components and membranes where practical. Thermal Design * Design an active cooling solution including: * Heat spreader and/or heat pipe for SoC * Heatsink. * Fan integration. * Airflow path and vent placement. * Cooling solution should be suitable for a modern mobile SoC. PCB Outline Design (no electronics work) * Create mechanical PCB outline DXF files for: * Mainboard. * Controller boards. * Power/volume button boards. * Any additional daughterboards. * Electrical design is not required. * PCB outlines should be exportable to DXF for import into KiCad. External I/O Integration * Integrate housing cutouts and mounting provisions for: * 2 × USB-C ports. * Mini or Micro HDMI port. * 3.5 mm headphone jack. * MicroSD card slot (if space permits). Battery Integration * Integrate battery pack(s) totaling: * Minimum capacity: 6000 mAh. * Preferred capacity: 7000–8000 mAh. * Consider safety, mounting, serviceability, and weight distribution. Size will be up to the developer, as long as sourceable. To work together with the creator to find the right size Deliverables * Complete 3D CAD assembly. * STEP files. * Manufacturing-ready housing geometry. * DXF exports of all PCB outlines. * Basic assembly documentation. * Renders and exploded views. * 2-3 month timeline (by end of July/August 2026) Information Provided * Display datasheets. * Existing concept CAD. * PCB component placement information. * Mechanical constraints and target dimensions. ## Please Include * Relevant portfolio examples. * Experience with handheld electronics, gaming devices, or consumer products. * Estimated timeline. * Estimated cost. Please do not send generated AI responses with quotes, these will be ignored! Looking forward to working with you!
