Office Chair Chassis Research and Development

Office chair chassis research and development involves multiple core aspects, including structural design, material selection, performance optimization, and the application of new technologies.

Mainstream Chassis Structural Types

Currently, there are three mainstream types of chassis in the industry:

1. Mechanical Spring Chassis: It relies on the elastic force of springs for reclining adjustment. It has a relatively low cost but limited adjustment precision, only meeting basic office needs, and is commonly found in entry-level products.
2. Cable-Controlled Chassis: It controls the gas rod and springs through paddles, supporting multi-position angle adjustments. It is suitable for most corporate office scenarios, balancing comfort and cost.
3. Carbon Fiber Cable-Controlled Chassis: It uses carbon fiber composite materials for core components, reducing weight by 30% and enabling infinite angle adjustments (90°-135°). It is suitable for prolonged sitting and short breaks. For example, the carbon fiber cable-controlled chassis from Guangdong Jingyi Furniture combines a synchronous backrest and seat swing function, reducing spinal pressure through the联动 (simultaneous movement) of the backrest and seat, with technology at the leading domestic level.

Material Innovation and Performance Breakthroughs

Material selection directly affects chassis performance:

• Aerospace Glass Fiber Material: Sihoo's "Sixth-Generation Space Chassis" uses aerospace glass fiber, solving the technical challenge of increasing reclining angles and achieving a 145° golden large reclining angle, close to a lying-down position.
• Special Glass Fiber Springs: The developed high-performance glass fiber material features a large elastic travel, balanced elasticity, durability, and corrosion resistance. It has passed 300,000 durability tests, showing no degradation after repeated use, significantly improving chassis lifespan.

Core Responsibilities of R&D Engineers

1. Full-Process Development: Lead structural design, industrial design, and material selection. Use software such as SolidWorks and AutoCAD for modeling, drawing preparation, and technical documentation compilation. Ensure compliance with domestic and international standards such as ISO, BIFMA, and GB from concept design to mass production.
2. Performance Optimization and Cost Control: Solve production and customer feedback issues through structural and process optimization, such as improving adjustment precision, reducing weight, or minimizing material waste.
3. Technology Trend Tracking: Explore the application of new technologies such as biobased materials and intelligent adjustment modules, for example, integrating sensors for automatic angle adjustment or using recyclable materials to enhance environmental friendliness.

Office chair chassis research and development requires balancing functionality, cost, and user experience. Material innovation and structural optimization are key, and engineers need interdisciplinary knowledge and full-process management capabilities.
