UT Move

Led the mainboard layout and stacking architecture development for a LoRa/WiFi dual-mode walkie-talkie device, progressively optimizing component density and internal space utilization within fixed product dimensions.

• Mainboard iterations: Defined three configurations (Type 1-3), trading off different size targets and function combinations while systematically evaluating PCB area utilization and thermal paths.
• Stacking architecture: Compared the original walkie-talkie stacking with two new form-factor proposals (UT Move Option A / B), defining the 3D relationships between PCB, battery, and antenna.
• Wearable form studies: Explored wearable stacking formats and foam form-factor studies, balancing battery life, product volume, and wearing ergonomics.

Extended from the UT Move product context, I defined an entire UniFi hotel ecosystem — including UTP Touch Max, UA Hotel Reader, UC Control Dial, and UniFi UGP — to build a complete in-room and out-of-room interaction experience.

• UTP Touch Max: A large-screen touch device for lobby or guest room, integrating meeting and environmental control.
• UA Hotel Reader: The door-access device outside each guest room, using NFC for check-in and identification.
• UC Control Dial: An in-room scene control dial for quickly switching between lighting, music, and AC modes.
• UniFi UGP: A large in-room touch strip integrating voice and scene synchronization.

Designed complete user flows for two scenarios — first-time and returning guests — creating a seamless, intuitive check-in experience while reinforcing the hotel brand memory.

• First-time check-in: Mobile booking → walk to the room (no front desk) → tap Hotel Reader via NFC → light and sound guide entry → Control Dial sets the room scene.
• Check-out & cleaning cue: After the guest leaves, the Reader screen automatically switches to a "Clean the Room" prompt, triggering the housekeeping workflow.
• Returning guest personalization: On a second stay, the system automatically recognizes the guest and pre-sets lighting, music, and ambient scenes based on prior behavior — reinforcing brand recall.

From device level to scenario level, I defined a full system architecture ensuring that all devices operate in unison through UniFi Console/Switch/AP.

• Device topology: Console/Switch/AP as the core, connecting TALK, GP, Control, and Reader device types to form a hotel-grade networking topology.
• Before check-in: Web or front-desk reservation → system sets the room number → Guest Point activated → tap Hotel Reader → check-in complete.
• After check-in: Control Dial provides preset scene modes (lighting, curtains, TV channels, music) for quick switching by the guest.
• Check-out: External notifications (including alarms) delivered via Talk Max; use the room card or phone to tap Hotel Reader for lock-out.
