About Cadence of the Spiral 主要功能：動態裝置

《螺旋律動》探索時間作為一種富有彈性、互相關聯且充滿生命力嘅存在。一條不銹鋼彈簧鋼帶由三十隻機械臂塑造成不斷演變嘅形態。機械臂以微妙而相位錯落嘅節奏移動。當螺旋呼吸、扭轉並重新組織自己時，每一刻都絕不相同。呢件作品靈感源自機械錶嘅發條。佢將盤繞嘅金屬重新詮釋為儲存能量同時間流動嘅載體。動作並非重複，而係透過受控嘅變化去展現轉變。時間並非被量度，而係被感受。

Unique Properties: A long stainless-steel spiral is dynamically deformed by independently actuated arms, generating continuous reorganization through tension and release. Unlike static sculpture, the form never settles; it is constantly restructured into shifting orders. The spiral functions as a physical model of time—elastic, unstable, and relational. Controlled irregularity replaces mechanical uniformity, allowing viewers to perceive time not as measurement, but as a living and evolving order.
Dimensions & Packaging: Material: Blast-finished stainless spring steel (0.3 mm thickness, 80 mm width)
Spiral pitch: 100 mm
Number of turns: 10
Control: PC-based control system
Installation footprint: Approx. 2000 mm × 2000 mm × 2000 mm
Power: AC 100–240 V
Tags: Kinetic art, Spiral structure, Time perception, Mechanical rhythm, Parametric design, Stainless steel sculpture, Dynamic installation, Temporal form
Production Technology: A custom-fabricated stainless-steel spiral plate forms the core structure, paired with a bespoke linear actuation system developed for this work. Most mechanical components—including joints, mounts, and structural interfaces—were custom-designed to enable precise distributed deformation. Motion is coordinated through a PC-based control architecture enabling synchronized, phase-shifted oscillations. Parametric modeling and simulation optimized stress distribution and torsional balance.
Design Challenge: The primary challenge was balancing structural stability with expressive flexibility. The spiral required sufficient rigidity to maintain form, yet enough elasticity to allow dynamic deformation. Managing distributed mechanical stress while achieving organic motion demanded extensive iteration. Technological constraints of synchronized actuation and material fatigue also required innovative solutions to preserve both safety and poetic integrity.
Research: This practice-based design research explores time as a spatial and kinetic phenomenon. Through iterative prototyping combining mechanical engineering and artistic experimentation, parametric modeling, structural simulation, and motion analysis were employed. Audience observation during exhibitions informed the study. The research identified perceptual shifts generated by micro-irregular motion, demonstrating how controlled instability enhances emotional engagement and contributes to contemporary kinetic art and experiential design.
Inspiration: Inspired by the mainspring of a mechanical watch, Cadence of the Spiral reconsiders the spiral beyond its functional role. The tightly wound strip of metal appeared as a vessel containing latent energy and rhythm of time itself. When gently lifted, it responded with subtle motion, as if about to begin a heartbeat. The spiral thus emerged not as an object, but as a physical manifestation of invisible time—an embodiment of tension and release within temporal experience.
Project Duration: The project began in Tokyo in March 2025 and was completed in November 2025. Prototyping and structural validation were conducted in Tokyo. Developed in collaboration with Seiko Watch Corporation to explore the cultural and mechanical heritage of horology, the work was exhibited in Japan and is currently being prepared for international presentation.
Operation Flow: The spiral slowly shifts between tension and release. As the supporting arms extend and retract, the form breathes, twists, and reorganizes itself. There is no fixed choreography; instead, subtle variations create moments of alignment and misalignment. Viewers experience a continuous transformation—sometimes synchronized, sometimes slightly off—evoking the sensation of time that never fully repeats yet always returns.
