I need a mechanical engineer to develop a concept for a compact motorized ALT/AZ polar-alignment platform, supported by preliminary calculations, component selection and packaging checks. This work will become the basis for subsequent detailed engineering and implementation. The main priorities are mechanical simplicity, low total cost, easy manufacturing and straightforward assembly. Reference and requirements - Avalon Instruments UPAS is the reference for overall size and form factor: approximately 179 × 179 × 158 mm. Please account for the complete moving envelope, motors, manual knobs and cable clearance. - The platform sits between a tripod and an equatorial telescope mount, providing fine ALT/AZ adjustment for polar alignment. - Target supported mass: 25–30 kg total, including mount, telescope, accessories and any counterweights. - Approximately ±5° adjustment on both axes. - Motorized operation and manual knob adjustment when powered off, without releasing locks, disengaging clutches or operating selectors. - ALT motor attached to the moving top plate and contained within its footprint. - AZ motor positioned above the rotating plate supporting ALT. - Initial mounting interfaces: original ZWO AM5, Sky-Watcher Star Adventurer GTi and ZWO TC40 tripod, using interchangeable adapters. UPAS reference: [login to view URL] Preliminary FreeCAD models are available. You do not need to preserve the existing mechanism: simpler alternatives are welcome. The internal UPAS mechanism has not been verified; the reference establishes the intended functionality and compactness. Required deliverables 1. Complete ALT/AZ concept Explain the mechanisms, fixed and moving parts, load paths, motor drives, manual operation and position retention when powered off. 2. Dimensioned 3D concept assembly Establish the main geometry, travel, motor positions and interfaces. Check clearances throughout combined ALT/AZ movement, including access for knobs, fasteners and assembly. 3. Preliminary engineering calculations State load cases, centre-of-gravity assumptions and margins. Estimate forces, moments, motor torque, manual knob effort and relevant strength/stiffness requirements. Distinguish calculated results from assumptions requiring later verification. 4. Real component selection Identify suitable motors, screws/nuts or gears, bearings, guides and other components using actual manufacturer references and specifications wherever possible. 5. Materials and manufacturing approach Propose materials, preliminary thicknesses and main dimensions for custom parts. Explain how they can be manufactured economically through PCBWay and/or JLC CNC. 6. Preliminary BOM and cost estimate Separate purchased components from custom parts, with quantities, supplier references and clearly stated cost assumptions. Prefer standard components, few machining setups and minimal special tolerances. 7. Engineering handover Deliver editable source CAD, preferably FreeCAD, STEP files, calculation sheets and a short report identifying design decisions, unresolved issues and the checks needed during detailed engineering. Scope boundary This phase does not require a complete production drawing package, comprehensive FEA, electronics, firmware or a physical prototype. However, it must provide more than a visual model: the mechanism must be sufficiently defined and calculated for another person to continue detailed engineering without having to redesign it from scratch. Please provide your timeframe, relevant mechanical-design examples and proposed CAD format. Clearly identify any exclusions. AI usage disclosure needed also when answering to the post

Hi, I’m an experienced mechanical CAD designer specializing in mechanisms, assemblies, product development, and manufacturing-oriented design. I can develop the compact ALT/AZ platform concept with defined load paths, moving interfaces, motor locations, manual adjustment, locking/retention, and clearance throughout the full ±5° movement. I can build the concept assembly in **FreeCAD and/or SolidWorks**, with STEP output, and perform preliminary calculations for load cases, centre of gravity, moments, required motor torque, manual effort, strength, and stiffness. I can also research and select practical motors, screws/gears, bearings, guides, and other standard components, then prepare a preliminary BOM and cost estimate using realistic manufacturer specifications. The design will focus on low part count, simple machining, economical materials, PCBWay/JLC CNC manufacturability, and straightforward assembly. I’ll clearly separate calculated results from assumptions and identify items requiring verification during detailed engineering. Deliverables can include the editable CAD assembly, STEP files, calculation sheets, preliminary BOM, and a concise engineering handover report. **AI usage disclosure:** I may use AI-assisted tools for research, documentation, or workflow support, but all CAD geometry, engineering calculations, design decisions, and final deliverables will be reviewed and controlled by me.

Hello, I reviewed your requirements, and the core challenge is developing a compact ALT/AZ mechanism that can safely handle 25 to 30 kg while retaining manual adjustment, motorised operation, stiffness, and full movement clearance within the tight UPAS inspired envelope. I would define the load paths, adjustment mechanisms, motor and transmission arrangement, bearings, interfaces, materials, manufacturing approach, preliminary calculations, component selection, and BOM so the concept is mechanically defined rather than just visually modelled. I can work with FreeCAD and provide editable source CAD, STEP files, calculation sheets, and an engineering handover identifying assumptions and unresolved points. I also use AI assisted tools where useful for research and documentation, while engineering decisions and calculations remain manually reviewed. Also a quick question, should the manual adjustment mechanism allow simultaneous motor and knob operation, or only manual operation when the motors are unpowered? Best Regards, Muskan.
