KeyStand – Portable Phone Holder with Keyring Function
Plastic Design Project
As part of the Design of Plastic Products course at DTU in Spring 2024, I participated in a project where we designed and analyzed a compact phone holder that also functions as a keyring. The product was developed with a focus on portability, usability, and suitability for mass production via injection molding.
Throughout the project, we followed a systematic process involving idea development, requirement specification, material selection (PPO/PS), CAD modeling in Fusion 360, and simulation-based optimization of geometry and molding parameters. The design was validated through strength calculations and Moldex simulations to ensure short cycle time, minimal warpage, and limited sink marks.
The project concluded with a sustainability assessment comparing two lifecycle scenarios. A complete 3D mold design (CAD) was created, including gating system, ejector pins, and cooling channels.
