Sato Lab
Machine-translated · View original
A lab that creates new structural forms from materials, mechanics, and geometry.
AboutAbout the lab
Toward structures that create spaces of “komorebi,” dappled sunlight through trees
Sato Lab explores and proposes structural forms for architecture based on material properties, mechanics, and geometry.
The lab studies the performance of materials that have rarely been used in architectural structures, and proposes structural forms and design methods that make the most of them.
Using original structural analysis software for form-finding, the lab puts into practice a design method in which form is determined by mechanics.
The lab aims to create natural spaces like “komorebi” (dappled sunlight through trees) with see-through structures made of slender members.
Key terms
- Form-finding
- A method of finding a form suited to a structure by calculating the balance of forces and similar conditions
- Multi-objective optimization
- A calculation that searches for a form that satisfies several goals at once, such as strength and the way light enters
- Buckling
- A phenomenon in which a slender column or thin plate under compressive force suddenly bends by bulging sideways
ResearchResearch themes
Transparent structures made of slender members can act as “filters” that control the environment, creating spaces like komorebi (dappled sunlight through trees). Through control of mechanical and geometric forms and practice at the workshop scale, the lab aims to establish design methods that generate form.
*Illustrative imageBase camps on the Moon and Mars
The lab proposes a construction method for structures with floors held up by tall legs on the uneven ground of the Moon and Mars, which deploy using springs and similar means with minimal mechanical control. The lab aims to carry out a demonstration on the lunar surface with a small prototype.
*Illustrative imageShape optimization and machine learning
The lab studies multi-objective optimization that optimizes mechanics and the light environment at the same time, and local optimization that strengthens thin plates by adding dimple-like depressions. It also pays attention to the similarities between form-finding and machine learning.
*Illustrative imageDetermining the buckling strength of each member
The lab is trying to extract the buckling strength of each individual member by condensing the buckling calculation of an entire three-dimensional frame. Using this as an objective, it is also possible to optimize the shape.
*Illustrative imagePatterns that create “komorebi”
It is said that a one-dimensional wave with “1/f fluctuation” feels natural and comfortable. The lab is trying to extend this to two dimensions, apply it to images, and use it to create patterns like “komorebi.”
