This development of SPARQ brand peripheral products aims to extend the expression of the brand’s core technology—the SPARQ Diagnostics automotive health monitoring system—from digital products to physical products. The design continues the brand’s core philosophy of “intelligent diagnosis, accurate prediction,” transforming data flow, signal transmission, and vehicle engineering aesthetics into a perceptible design language. Through the integration of streamlined structures, the brand’s color scheme, and a responsive font, we systematically translated the digital product language of SPARQ Diagnostics into a diverse range of peripheral products. The final product is not merely a series of functional items, but also brand symbols embodying the core spirit of SPARQ, extending the product design language from “diagnosing vehicles” to “equipping life,” achieving full-scenario coverage of the brand experience.
