With over 14 years of experience as a mechanical engineer, I bring a unique blend of design, simulation, and manufacturing skills to your project. I've tackled countless projects that required intricate mechanical systems and it's safe to say that your Deployable Solar Array project is the kind of challenge I thrive on. For instance, answering your torque question: for a 180kg column rotating from 0° to 90° about a base pivot, we can expect peak torque at approximately 3960 N.m. And to counterbalance this effectively, I would estimate utilizing two gas springs (at an angle of approximately 45°) to exert a force of around 490 Newtons to keep the effort under 20 kg. Beyond just providing detailed designs and spreadsheets though - which I excel at using leading tools like SolidWorks and AutoCAD - my approach focuses on real-world applicability. Complex systems have many variables interconnected with one another and predicting their behavior demands experience. I not only design parts that are machine-friendly but also consider their impact on manufacturing costs and integration with other components which in this particular project is paramount. Lastly, my commitment to speed without compromising quality separates me from the rest. Your goal of deploying the EV charging station in just 15 minutes with two people and no crane is a significant challenge that requires not only smart design but also efficient execution. .

Peak torque depends on the center of gravity distance from the pivot (T = m × g × d). Once the CG location is confirmed, I can size the gas spring and mounting geometry to reduce manual effort to under 20 kg while maintaining a safe lifting profile. I’m a Mechanical Engineer with experience in mechanism design, kinematic analysis, structural design, and manufacturing-ready CAD. I can design the complete deployable solar array mechanism, including the lifting system, panel unfolding mechanism, gas spring/counterbalance sizing, fabrication drawings, BOM, and detailed manufacturing documentation optimized for laser cutting, bending, and welding. I have worked on motion mechanisms and heavy mechanical assemblies where kinematics, load paths, manufacturability, and ease of assembly are critical. I can deliver a practical design that is simple, reliable, and suitable for fabrication. Thanks.

For a 180 kg rotating column, peak gravitational torque at the start of lift is T = m·g·rCG = 1,765.8·rCG N·m. Assuming the CG is 1.0 m from the base pivot, peak torque is approximately 1.77 kN·m. To counterbalance this to under 20 kg manual effort, I would size the gas-spring system from the actual pivot-to-mount geometry; for example, with an effective 0.5 m moment arm, approximately 3.1–3.5 kN total gas-spring force at roughly 70–90° to the lever arm near initial lift would be a starting estimate, then verified across the full 0–90° motion. I am a Mechanical Engineer experienced in CAD, FEA, structural mechanics and mechanical design. I can develop the deployable column and six-panel unfolding mechanism as a true kinematic system, not a static CAD model. My approach will include CG and torque mapping through deployment, gas spring/counterbalance sizing, pivot and hinge design, motion/interference checks, structural validation in ANSYS, and manufacturing-ready SolidWorks CAD and fabrication drawings. I can also design around laser cutting, press brake forming and welded fabrication for practical production. Please share the column dimensions, CG location, panel dimensions/weights and transport envelope. Regards, Mohammad Haris

Option 1 – Dual Gas Spring + Manual Winch I propose a deployable solar array using a dual gas spring assisted column lifting system with a manual winch. The gas springs reduce lifting effort, while the winch provides safe and controlled operation. After the column is locked vertically, a cable-linkage mechanism automatically opens all six solar panels. The design is simple, reliable, easy to manufacture, and requires minimal maintenance. Option 2 – Fold-Out Panel System I propose a simple fold-out solar array with a manually lifted column and hinged solar panels. Once the column is locked in the vertical position, each panel folds outward and locks into place. This design uses fewer moving parts, is easy to fabricate, cost-effective, and allows fast installation within 10–15 minutes by two people.

Estimated Answer: Assuming the 180 kg column's center of gravity is approximately 1 m from the base pivot, the peak starting torque is about 1,765 N·m (180 × 9.81 × 1). To reduce manual effort to under 20 kg (~196 N), I'd evaluate gas springs in the 1,200–2,000 N range with an initial mounting angle around 25–35°, then optimize the exact force and mounting points through kinematic analysis and CAD simulation. Hi, I'm a Mechanical Design Engineer with extensive experience in SolidWorks, kinematic mechanisms, fabrication-ready CAD, and manufacturing drawings. I can design the complete deployable solar array mechanism, including the rotating column, panel unfolding system, gas spring/counterbalance mechanism, and detailed fabrication drawings for laser cutting, bending, welding, and assembly. The design will be optimized for manufacturability, safe deployment, and one-person operation while meeting your transport and deployment requirements. I can also perform motion validation and interference checks before fabrication. I'd be happy to discuss the concept and share relevant mechanical design work upon request.
