AI Technical Summary

Benefits of technology

This patented technology improves upon previous designs by adding an elastic material called a damper made from silicone or other materials around it for better noise reduction performance during operation. By placing this material inside the design instead of just one layer on top of another, there are fewer points where they may fail due to excessive bending stress caused when heavy loads pass through them. Additionally, the system includes indicators attached to its components such as settable plates to help users make informed decisions about how much pressure should be applied beforehand. Overall, these improvements improve the overall functionality and durability of the product's suspension systems.

Problems solved by technology

This patented technical problem addressed in this patents relates to controlling the compressive displacement of springs used in railway systems like rail suspensions without causing excess strain due to environmental factors including temperature variations over time. Existing solutions involve adding extra weight to the suspended device itself or applying static pressure instead of allowing gravity to act upon them. These techniques result in increased stress levels and reduced resonance performance compared to desired results.
