Design 30 m Underwater Action Camera

I am developing Spear Vision, a professional-grade diving and freediving mask with an integrated underwater camera for freediving and spearfishing. I am looking for an experienced industrial designer/mechanical engineer with underwater product, rugged electronics, wearable technology, or dive-equipment experience to help develop the first functional prototype. Product concept The product will be a diving mask with an integrated camera system designed for use underwater. The target specifications are: 4K video recording Strong low-light performance, potentially using a Sony STARVIS-type image sensor Target operating depth of approximately 30 metres Internal rechargeable battery Magnetic or pogo-pin charging connection Internal eMMC or similar flash storage Wireless data transfer to a smartphone when the user is on the surface or in a boat Wired data transfer as a backup option Professional, durable construction rather than a disposable action-camera design Minimal need to open the housing, reducing the risk of seal damage Heat dissipation through a metal heat spreader or heat sink connected to the housing The product must be designed with comfort, balance, visibility, waterproofing, serviceability, and diver safety in mind. Scope of work I would like assistance with the following: Product architecture Recommend a practical layout for the camera, battery, storage, charging system, and electronics. Assess whether the electronics should be integrated into the mask body, a detachable module, or a separate sealed pod. Identify major technical risks and recommended solutions. Mechanical and industrial design Develop the external form and internal arrangement of the product. Maintain a comfortable fit and appropriate weight distribution. Prevent the camera and electronics from obstructing the diver’s vision. Design suitable access points for professional servicing without requiring frequent opening. Consider corrosion-resistant materials suitable for saltwater use. Waterproof housing design Design a sealed enclosure suitable for the target depth. Specify appropriate O-rings, gaskets, seals, fasteners, and materials. Consider pressure loading, lens-window strength, mechanical tolerances, and galvanic corrosion. Produce a sealing strategy that can be pressure-tested and repeatedly serviced. Thermal management Develop a practical method for transferring heat from the electronics to the external housing or surrounding water. Consider heat spreaders, thermal pads, conductive materials, and electrical isolation. Identify possible overheating risks during 4K recording. Prototype-ready CAD Create detailed 3D CAD models of the housing and relevant components. Provide manufacturing drawings with dimensions, tolerances, materials, and surface finishes. Design parts suitable for CNC machining, injection molding, or high-quality prototype manufacturing. Include mounting features for the camera lens, circuit board, battery, storage, magnets, charging contacts, and seals. Prototype development support Recommend suitable prototype materials and manufacturing methods. Help prepare a bill of materials. Identify off-the-shelf components where appropriate. Support the transition from an early prototype to a more manufacturable design. Testing plan Create a preliminary test plan for: Leak testing Pressure testing Repeated opening and resealing Saltwater exposure Corrosion Thermal performance Impact and drop resistance Camera and charging reliability Clearly identify which tests must be performed by a qualified laboratory or specialist manufacturer. Expected deliverables The selected freelancer should ideally provide: Initial feasibility assessment Product architecture proposal Concept sketches or layout options 3D CAD assembly Detailed housing and component models Engineering drawings Seal and gasket specifications Preliminary bill of materials Thermal-management concept Prototype manufacturing recommendations Risk assessment and design-for-manufacturing recommendations Waterproof and pressure-testing plan Documentation that can later be provided to an electronics engineer, prototype manufacturer, or investor Important limitations This is an early-stage project, and I am currently working with a limited development budget. I would prefer to proceed in phases, rather than commissioning a complete production-ready design immediately. The first phase should focus on: Reviewing the concept Identifying major technical risks Producing a practical mechanical layout Creating an initial CAD concept Estimating the cost and complexity of a functional prototype The first prototype does not need to be production-ready, but it must be designed professionally enough to support further testing and development. The freelancer must not assume that a 3D-printed housing is automatically safe for diving. Any prototype intended for underwater use must be pressure-tested appropriately, and the final product will require professional engineering validation. Ideal freelancer experience Please apply only if you have relevant experience in one or more of the following: Underwater cameras or dive equipment Waterproof or pressure-resistant enclosures Rugged electronics Wearable technology Consumer electronics housings Industrial design for outdoor or marine products O-ring and gasket sealing CNC-machined or molded waterproof components Thermal management for compact electronics Saltwater-resistant materials and corrosion prevention Design for manufacturing Experience with SolidWorks, Fusion 360, Creo, or a comparable professional CAD platform is preferred. Application requirements Please include: Examples of similar underwater, sealed, wearable, or ruggedized products Your experience designing pressure-resistant housings The CAD software you use Your proposed approach to the project Your estimated hourly rate or price for the first phase The estimated time required for the first phase Any technical concerns you immediately see in this concept I
