BangPole-Valence-Connection reimagines space frame construction through molecular network logic, where wooden poles function as 'valence electrons' connecting through PVC joints acting as 'molecular nodes.' The system emerged from a provocative question: 'If we want to create a molecule-like structure, what could it be?' By trimming only pole tips (not modifying entire lengths), the design maximizes adaptability while minimizing labor. PVC joints—widely available, inexpensive, and strong—enable tool-free assembly using only bolts and nuts with epoxy reinforcement.
