Inspired by the double-spiral pattern on a terracotta-colored pottery bottle from the Neolithic Age, this study transcends traditional archaeological and art-historical interpretations to construct a meta-model named the "Tri-State Theory of the Dual Spiral Spring." Using a pair of rigidly connected spiral springs as its core metaphor, the model distills three fundamental states of a system—Equilibrium State, Tightening State, and Loosening State—and reveals the law of their dynamic cycle. The research first establishes the mathematical and physical foundations of the model, demonstrating that it can be simplified to a linear segment as an elemental structure, and its dynamic mechanism can be interpreted through the principle of wave reflection. Building on this, the paper systematically verifies the model's powerful universality: at the micro level, it provides a philosophical schema for the holistic correlation in quantum entanglement; at the macro level, it explains the climatic cycles of Earth and the life-death rhythms of celestial bodies; on the scale of human society, it accurately describes interactive tensions from interpersonal emotions to international geopolitics; in the field of ecological governance, it offers in-depth analysis of contrasting cases, from the "human retreat leads to desert retreat" miracle in the Mu Us Desert to the embankment breaches at Poyang Lake. Furthermore, this study achieves a trans-temporal dialogue with ancient Eastern wisdom. The model not only aligns with the ideas of "Reversion is the movement of the Dao; Weakness is the function of the Dao" from the Dao De Jing, but its core framework of "two poles and three states" can also naturally演绎 the cosmic generative process of "The Dao begets the One; the One begets the Two; the Two beget the Three; the Three beget all things." It also provides a scientific modeling perspective for the practices in Kan Yu (FengShui) that seek systemic harmony and balance. In summary, the "Tri-State Theory of the Dual Spiral Spring" is not merely a meta-model with solid mathematical foundations, but also a system thinking paradigm that connects antiquity with modernity and bridges the humanities and sciences. It provides a unified and explanatory framework for understanding dynamic equilibrium phenomena across numerous fields, from nature to human society.
