Overview
As part of a design team, I contributed to the digital transformation of Y-Fang’s sealing machine and focused on user research, interaction logic, and UI design.
By bridging mechanical habits with intuitive touch-based interactions, we built a solution that significantly improved productivity and reduced errors, while opening up opportunities for better data management and maintenance efficiency.

Background
As the beverage industry grows, traditional sealing machines face increasing pressure to modernize. Analog interfaces often lead to operational errors, inefficient training for new staff, and a lack of data visibility for managers and technicians.
This project aimed to deliver a user-friendly digital interface that meets the needs of both operators and manufacturers.

Research
We conducted on-site visits to beverage stores and manufacturing partners, directly operating the machines to understand existing workflows. Interviews with store managers, staff, and technicians revealed key pain points:

New staff often struggled with training, forgetting maintenance tasks or misconfiguring parameters.
Experienced staff required shortcuts to maintain speed during peak hours.
Technicians lacked access to machine fault history, making repairs time-consuming.
These insights informed a restructured information architecture and interaction logic that balanced learnability for beginners with efficiency for experts.

Outcomes
Seamless Digital Transition
Preserved familiar mechanical workflows while adding real-time feedback and error prompts, reducing friction in adopting the touchscreen interface.
Clear Information Hierarchy
Consolidated multiple machine settings into a well-structured interface with visual layers and tabs, reducing cognitive load and minimizing misoperations.
Efficiency & Learnability Balance
Designed layouts aligned with common digital software patterns: main operations on the right, menus on the left, critical shortcuts at the bottom-right. This ensured quick learning for new users while retaining shortcuts for experienced staff during peak hours.
Maintenance & Repair Support
Introduced features for technicians and managers, such as scheduled maintenance reminders and access to fault history, enabling preventive care and faster troubleshooting.

Key Learnings
Working with a product design team to digitize a physical machine interface was a first for me. I learned how to adapt to mechanical workflows, coordinate with a traditional manufacturer less familiar with digital practices, and contribute to a design system that balances immediate usability with long-term scalability.
