Core Viewpoint - The article discusses the advancements in intelligent suspension systems by Shijia Technology, emphasizing the transition from traditional suspension systems to more advanced air suspension systems, which enhance vehicle comfort and stability [1][4]. Group 1: Company Overview - Shijia Technology recently completed a multi-hundred million yuan Series A financing round, led by Xingyuan and several industry capitals, with support from Tongji University Innovation Fund and local government [1]. - The funding will be primarily used for the R&D of third-generation fully active suspension technology and the establishment of an advanced intelligent manufacturing center with an annual capacity of 500,000 sets [1]. Group 2: Product Development - Shijia Technology has developed an air suspension system that adjusts vehicle height and suspension stiffness dynamically by regulating air pressure, improving ride comfort and handling stability [1][2]. - The company has introduced two major products: the "Eight-in-One Integrated Closed Air Supply Module" and the "Fully Active Air Suspension System" [2]. - The Eight-in-One module integrates multiple functions, resulting in a smaller, quieter, and more efficient system, which can reduce costs by thousands of yuan compared to mainstream products, facilitating the penetration of air suspension into vehicles priced around 200,000 yuan [2][4]. Group 3: Technical Innovations - The Fully Active Air Suspension System represents an upgrade from traditional semi-active systems, allowing for real-time adjustments to spring stiffness and vehicle posture, enhancing performance by approximately 30% compared to traditional solutions [3][4]. - Shijia Technology's core technology includes a proprietary "Adaptive Tuning Algorithm," which adjusts vehicle posture and suspension stiffness based on road conditions and driving states, improving the driving experience [4]. Group 4: Challenges and Solutions - The company faces three major technical challenges: ensuring long-term operation under closed conditions, achieving high responsiveness and precision in the electromagnetic valve system, and integrating the structure to reduce noise and installation difficulties [5]. - Shijia Technology has made significant progress in material, structure, and process optimization to meet high standards for airtightness, pressure retention, and durability, allowing the system to operate at pressures up to 15 bar for over 500 hours [5]. - The integrated design approach enhances system consistency and performance while lowering costs, aligning with the founder's vision of transforming the Chinese automotive industry from "rubber shoes" to "real air-cushioned shoes" [5].
