Open it.

It is a toolbox with physical presence.
It requires two fingerprints to unlock.^¹

Tools.

There are many tools.
They all call it ∩ (n).

When ∩ (n) is applied to a problem and its context, x, the resulting state is called y.^²

They make tools.

Close it.

Without a perfect fit on every side, it cannot be closed.

Observe. Question. Hypothesize. Experiment. Analyze. Conclude. Infer. Verify. Observe. Question.

The cycle repeats.

The toolbox is a sphere.^³

1. Bridge (跨). Founded by two partners with interdisciplinary backgrounds in graphic design, architecture, and performance art. They understand design as both a mode of communication and an interdisciplinary practice.

2. n(x) = y.^⁴

3. Flexible Structure. A design methodology is a mechanism that is adjustable, responsive to feedback, and capable of evolving.

4. arch arch is a research-driven design practice. It focuses on the design methodology ∩, investigating each project's specific context x to reconstruct cognition (meaning) and perception (experience), y.
