During my undergraduate studies, I frequently relied on CPU and GPU-intensive applications such as SOLIDWORKS and Autodesk Fusion 360 for coursework, including Finite Element Analysis, and for contributing effectively to my senior capstone project. Given the limited performance and availability of campus computer labs, it became necessary to use a high-performance tablet. However, the power demands of design and simulation tasks led to significant battery limitations during mobile use.
To address this, I implemented a custom mobile power solution using two USB-C PD power banks capable of supplying 20V DC, matching the output of the laptop’s OEM charger. While these power banks offered sufficient power delivery, their general-purpose design lacked integration features for mobile engineering workflows.
To resolve this, I designed and fabricated a modular mounting system using FDM 3D printing. This system included custom-fitted enclosures with integrated rail attachments and corresponding docks. These docks were installed both on the laptop chassis and inside my backpack via a rigid plastic sheet with loop fastener backing, allowing for secure, organized stowage during transit. This setup enabled uninterrupted CAD and simulation work while mobile, optimizing both efficiency and system reliability in field and academic environments.
