About Transition 展览设计

《过渡》是一场花艺展览，以当代方式呈现拥有1400年历史的日本花道（生け花）传统。展览采用开放式布局，不设后墙，观众可自由穿行，从多个角度而非仅从正面欣赏每一件花艺作品。自然光与感应式照明随一天时间的推移而变化，使空间与鲜活的花材持续呈现出不同面貌。模块化展台由可回收树脂3D打印制成，可拆卸并重复使用。平整无障碍的地面确保所有区域均可通行。

Unique Properties: An immersive flower exhibition engaging all five senses, tracing 1,400 years of ikebana and the kado philosophy of the life of flowers. Fresh floral works, shifting sunlight, and responsive lighting continuously transform both space and experience. A wall-less, open configuration overturns traditional frontal ikebana viewing, inviting active participation and enabling unrepeatable, time-based engagement with floral art.
Dimensions & Packaging: Exhibition area: approx. 300 sqm.
Monitor fixtures: 1965 mm Width x 470 mm Depth x 1195 mm Height.
Large stage: 3000 mm Width x 4200 mm Depth x 300 mm Height.
130-size modular lighting pedestals in 3 types: A: 400 mm Width x 400 mm Depth, B: 500 mm Width x 500 mm Depth, C: 800 mm Width x 800 mm Depth.
All components are designed for disassembly, reuse, and full barrier-free accessibility.Exhibition area: approx. 300 sqm.

Production Technology: The exhibition structure was realized using recyclable resin-based 3D-printed pedestals, minimizing waste and enabling modular reuse for future installations. The lighting design incorporated responsive LED systems to simulate natural transitions. Spatial modeling and daylight simulation were conducted using Unreal Engine to test sun paths and visual conditions, allowing for precise environmental calibration. Materials include wood, recycled steel, and living floral elements.
Design Challenge: Traditional ikebana shows erected one-off timber walls and fixtures, then scrapped them. We challenged that legacy, adopting a reusable system that slashes physical build. Pedestals are 3-D-printed from recyclable resin, designed for quick disassembly, transport, and redeployment, cutting material use and waste. With level floors and wide clearances, the fully barrier-free layout marries sustainability to inclusive design.
Research: In this show we discarded the rear wall once mandatory for classical ikebana and used self-standing fixtures, letting visitors wander freely. Single-use timber walls became reusable, 3-D-printed units of recycled resin, proving ikebana can travel to sites once impossible. Surveys showed 90 % of attendees were first-time ikebana viewers, revealing new audiences. Energized by this success, we are already planning the next “new-generation” flower exhibition.
Inspiration: Ikebana is a centuries-old tradition that unites time-based and spatial art. To honor this duality, we removed the rear wall once deemed essential, shaping a fluid gallery where changing daylight, responsive lighting, and living flowers mingle in shifting layers. Visitors roam freely, viewing each arrangement from many angles while bespoke Unreal-Engine simulations refined sun paths and sightless, letting space and work animate each other.
Project Duration: The project started on April 13, 2025, and concluded on April 20, 2025. It was exhibited at the “Gallery EAST” of Expo 2025 Osaka, Kansai.
Operation Flow: Visitors freely move through the open, wall-less gallery, exploring ikebana arrangements from multiple angles. Natural and dynamic lighting interact with fresh flowers, creating constantly shifting scenes. This spatial and sensory engagement encourages personal interpretation, breaking from the static, front-facing norms of classical ikebana.
