SyncOne Blends AI Motion Capture with a Minimal Design
SyncOne is a pleasure device developed with AI-based video motion capture and high-precision algorithms that enable real-time mechanical control. The system connects with PCs, mobile applications, and VR devices, allowing it to function across multiple interfaces. Its contact component is produced from transparent TPU using a two-shot molding process, resulting in a unibody design for easy removal and insertion. The section incorporates a sealing groove to prevent leaks and a diffuser that amplifies vibration power. These elements are designed for straightforward maintenance and cleaning. The base unit is equipped with a side waterproof airflow channel, PTC heating, and UVC disinfection lights, enhancing usability for sterilization and drying. Across the product, the design emphasizes grip comfort, simplicity, and convenience.

Intelligent Mechanics and Unibody Engineering Guide SyncOne
During the Engineering Validation Test (EVT) and Design Validation Test (DVT) stages, the design team, led by Lee Yi Chung, used 3D modeling and 3D printing to verify initial mechanical principles before developing simplified injection molds for early test components. Each version underwent mechanical evaluation and dimensional analysis, followed by incremental refinements. Through repeated adjustments to tolerances, load paths, and internal spatial configuration, the design achieved a more efficient mechanical transmission and an optimized internal structure.
The unibody element was informed by early experiments in soft resin casting using 3D printed molds, later progressing to metal 3D printed inner sleeves. This process was aimed at balancing material flexibility with structural softness, ultimately enabling a one-piece molded component with improved waterproofing and consistent manufacturing quality. Color, Material, and Finish (CMF) development focused on integrating visual and functional considerations. To address the common issue of fingerprints, sweat marks, and discoloration associated with long-term use, the surface underwent multiple rounds of finishing tests and material adjustments. CMF was treated as a core element of the SyncOne project, shaping both appearance and tactile interaction. Packaging was designed as part of the overall product experience. Beyond protection during transport, the packaging is intended to establish the first interaction between the object and the user, reflecting the design direction and values of Segai Design Lab.
