🏅 Achievement unlocked
As a solo designer, I gained a deep understanding of both front-end and back-end processes and transferred it into a feasible approach. I led the app interface, operational structure and gesture of the IoT product which would be compiled to usage and technical documentation.
Overall
Design an integrated smart home application, starting with air purifiers and scaling to support other potential devices (e.g. smart diffusers, cooking appliances). The app aims to provide seamless control across devices, spaces and comprehensive home management.
Design Challenge
- Cross-Product Logic Integration
- Real-Time Device Connectivity and Sync
- Multi-User, Multi-Space Scenarios
- Data Visualization & User Education
- System Scalability

N8 air purifier
Functionality
Autonomous air purifying system that navigates dynamically using feedback from fixed sensors (e.g., N7 the best selling product). Detects PM2.5, PM1.0 and VOCs. Supports remote control via app, mobile scheduling and air quality history tracking which will be optimized to focus on high-pollution areas at next route.

Use case
Ideal for large spaces—offices, schools, exhibitions, or homes with high airflow variation—especially in polluted areas.
Design challenges
- Requires smart coordination between mobile and fixed devices.
- Must map and adapt to changing indoor layouts in real time.
- Needs to visualize air quality changes clearly and interactively.
- Must respond instantly to hight-pollution area and time period with automated routing.
How it works?
The air purifier can move, as if a butler decides which solution would be taken according to different situations. During the implementation, N8 will arrange the best patrol cleaning plan for customers' space based on the current air quality by itself. How to judge the situation? It is based on the data before and after at the same area to determine the cleaning strength of the machine. And receiving the fixed-area data of the N7 (the small air purifier) is to determine whether to perform an emergency cleaning.

Interface

Smart Wok
Functionality
Built-in sensors (temperature, oil temperature, stirring frequency), timer reminder, automatic fire power adjustment and Bluetooth connection recipe guide.
Use case
Perfect for beginner cooks—prevents overcooking, smoke, overheating oil or confusion during recipe execution.
Design challenges
- Cannot visually recognize ingredients; relies on user input.
- Must accurately log cooking steps to create reusable, structured recipes.
- Needs to support a recipe-sharing community to reduce user errors.
- Must balance precision with flexibility for real-world cooking conditions.
Fregrancy
Functionality
Time- and scene-based scent release system with remote control via a mobile app. Uses modular, replaceable scent cartridges.
Use case
Designed for home users who want to shape their space through curated scents—whether to relax, energize or focus.
Design challenges
- Device can’t detect scent types due to hardware limitations.
- Product design inherited from a third party—requires full visual and experiential integration.
- Must align behavior and version updates with existing brand systems.
- Needs seamless syncing across hardware and app platforms.
