Bottle Design Engineering
DFM Checks
I developed an NX-embedded tool to automate the design for manufacturing (DFM) process, reducing risk and development time. It offered real-time validation of bottle designs with visual DFM compliance indicators, significantly lessening designers' workloads. Fully parametric models also streamlined development.
I developed an automatic Design Volume Calculator that started in Excel and became an NX-embedded tool. It checked and optimized part volumes for regional requirements and generated visuals for minimum, maximum, and target fill volumes, allowing designers to export files to Keyshot for brand renderings.
These innovations reduced validation time from 2 hours to 2 minutes per check, driving efficiency and accuracy in the design process.
As part of a global initiative to reduce supply chain complexity, I resolved cap fit issues for St. Ives' 20oz pack by consolidating two different neck designs into a single solution. Using NX CAD and Product Template Studio (PTS), I created a parametric model driven by the combined dimensions of both necks. By leveraging tolerance stack-up analysis and Unilever’s 3D printing lab, I optimized the design to ensure a perfect fit
Design Automation in Siemen’s NX
Unilever relied on suppliers for bottle push-up designs, resulting in frequent testing failures. To improve this, I analyzed an archive of bottle base dimensions for successful design patterns. Collaborating with a CAE expert, we created an optimal push-up structure.
I created a comprehensive how-to guide and trained designers globally, while partnering to develop a 'user-defined feature' for push-ups. This tool reduced design time from 1–2 hours to minutes and improved success rates during testing. By bringing push-up design in-house, we reduced risks, enhanced efficiency, and improved customer experience.
