Installing a larger fan on existing ventilation requires a clever adapter solution. To bridge the gap between an 80mm fan and standard 75mm ducting, we need to design an innovative adapter that not only fits snugly but also provides adequate airflow. The challenge lies in creating a secure connection that won't obstruct air flow while being easy to assemble and disassemble for cleaning or maintenance. To start, we'll focus on the mechanical aspects of the adapter. We can use plastic materials like ABS or nylon to create the main body of the adapter, as they are both durable and lightweight. The fan will be attached using screws or clips, ensuring a secure fit that won't vibrate loose over time.
