Design and photothermal coupling analysis of Kresling origami-based intelligent dynamic shading system

This study investigates the design and mechanical analysis of Kresling origami structures for reconfigurable intelligent dynamic shading system aimed at enhancing energy efficiency and thermal management. A mechanical model was developed using the principle of minimum potential energy, followed by 4D printing of specimens tested under compression, showing strong alignment with theoretical predictions. The research highlights the system's intelligent ventilation capabilities, incorporating adjustable fan blade units into the Kresling structure. Shape Memory Polymer (SMP) enables intelligent folding, while Carbon Fiber Reinforced Polymer (CFRP) ensures structural stability. The photothermal coupling analysis reveals how the system autonomously adjusts the shade angle in response to environmental changes, improving indoor illumination and thermal comfort. This intelligent shading system outperforms conventional permanent solutions, reducing energy consumption and enhancing user comfort, ultimately providing innovative insights for future energy-saving technologies in buildings.
