LAIA's engineering logic is built on direct intervention in physical touch. Jose Vinaroz internalizes the form of 'buttons' in daily interactions as the core visual anchor of the wheel body. The concave disc in the center of the wheel core, combined with the dopamine color system, breaks the inherent coldness of industrial components. Through precise two-color injection molding control of polymers such as TPU and PA, workshop technicians transform emotional color into perceptible physical feedback while ensuring extreme load-bearing capacity. This engineering setup, which forcibly injects emotional value into precision molds, gives the originally dull physical displacement a precise and vivid sensory landing.
