UIUX Design
Many people enjoy the feeling of personally washing their car at a self-service car wash, and I’m no exception. I often use my free time on weekends to wash my motorcycle at a self-service car wash. In terms of pricing, self-service car washes are much more affordable compared to car detailing, making it a valuable and convenient experience for budget-conscious individuals. However, I often encounter various issues, such as no available spots at the car wash, unclear equipment signage, machines eating money, or outdated equipment, among others.
Problem
In addition to the issues I personally encountered, I checked reviews of various self-service car wash businesses on Google Maps. I also conducted initial user experience interviews with three users and gathered feedback from those who had experience with car washes. Based on their responses, I compiled a summary of the common issues they encountered.
Empathy Map
Increase the number of registered Fugle members and improve the registration conversion rate.
Persona
Summarize the results of the empathy map into a user persona, categorizing the challenges users face into key pain points. This will help future solutions focus more effectively on addressing these specific issues.
User Story
User Journey Map
Incorporate the above story into the car wash experience journey, highlighting the frustrating moments users encounter within the process. By mapping these pain points, we can better brainstorm solutions and clearly identify when and where issues occur.
Value Proposition
User Flow
After identifying the value these features bring, outline the basic user flow (using booking and entering the car wash as examples). Design the flow and experience based on user stories, ensuring a smooth and intuitive process that directly addresses user needs and frustrations.
Wireframe + Low-Fi Prototype Testing
Create initial wireframes for the homepage, booking system, and car wash system, then conduct user testing to gather feedback. Continuously refine the design based on user insights.

Final Product UI
Business Model Development
Facility Usage Fees – Charging users based on the equipment and time used
Partnership Fees – Collaborating with car wash stations and relevant businesses for a fee
Equipment Setup & Commission – Installing smart car wash systems for other businesses and earning a commission
Unlimited Wash Plans – Subscription-based plans to attract frequent users
Loyalty Points System – Users earn points for washes, redeemable for washing time or car care products
Advertising & Sales Commissions – Featuring car care products on the platform and earning ad fees or commissions
Reflection on the Project
This project covers the entire research and design process, and I’ve tried to present the entire UI design system in a cleaner and more organized way.
However, due to the broad scope, each process required a significant amount of thought and evaluation. I hope that in future projects, I can refine each step further.
Additionally, the aspect that took the most time to think through was the booking system. What kind of model would be most helpful for users? Unlike restaurant or hotel booking systems, the car wash process has unique constraints that need to be considered.
I also hope to list the complete UI in the future and refine the mockups based on user feedback.
Thank you for reading, and feel free to discuss and share your thoughts!
