Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current shock assemblies lack the ability to dynamically adjust damping characteristics in real-time based on changing terrain or operational conditions, leading to suboptimal performance in various driving or riding scenarios, such as transitioning from paved to unpaved surfaces or during specific maneuvers like sprinting or hill climbing.
Innovation Solution
The integration of a live valve poppet assembly that allows for electronic adjustment of fluid flow paths, enabling the shock assembly to switch between open and firm settings remotely or automatically based on user input or sensor data, thereby modifying damping characteristics on the fly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the shock assembly uses fixed damping characteristics, then the structure is simple and reliable, but the performance is suboptimal when transitioning between different terrain types or operational conditions
Solution Approach 1:
The patent implements a live valve poppet assembly that can dynamically change the damping characteristics of the shock assembly in real-time. The poppet moves between different positions (recessed, transitional, protruding) to adjust fluid flow paths through the valve body, enabling the system to adapt to varying terrain and operational conditions rather than relying on fixed damping settings.
Solution Approach 2:
The invention changes the physical state and position parameters of the poppet component to achieve different damping characteristics. By varying the poppet's position (controlled by solenoids receiving electrical signals), the system modifies fluid flow resistance and pressure differential thresholds, thereby adjusting damping parameters to match different operating scenarios such as paved vs. unpaved surfaces.
2Productivity
If the shock assembly allows real-time damping adjustments, then the performance is optimized for different terrains, but the device complexity increases
Solution Approach 1:
The system incorporates sensors that detect terrain conditions and operational states, providing feedback to the control system. The controller processes this information and actuates appropriate solenoids to adjust the poppet position, creating a closed-loop feedback mechanism that optimizes suspension performance based on real-time conditions while managing system complexity through intelligent control.
Solution Approach 2:
The live valve poppet assembly serves multiple functions within a single integrated structure: it acts as both a flow control valve and a pressure regulation mechanism. The same poppet component manages different fluid flow paths (first and second fluid circuits) and responds to various operational modes (compression, rebound), reducing the need for separate specialized components and thereby managing overall system complexity.
3Extent of automation
If the shock assembly uses manual adjustment mechanisms, then the device complexity is reduced, but the ability to respond to changing conditions in real-time is lost
Solution Approach 1:
The shock assembly incorporates sensors and control systems that automatically detect terrain changes and operational conditions, then self-adjust the damping characteristics without requiring manual intervention. The system monitors its own state and environment, actuating solenoids to reposition the poppet as needed, enabling autonomous adaptation to varying conditions while managing complexity through integrated self-service capabilities.

Function Achieved in This Case
This solution enhances performance by allowing for real-time adjustments in damping, reducing wheel spin and improving power delivery during changes in terrain or operational conditions, such as when transitioning from paved to unpaved surfaces or during specific maneuvers, thereby optimizing ride quality and efficiency.
Implementation Method 1
the poppet may be manually or automatically (e.g., via a solenoid) moved between an open position, in which the poppet allows fluid to flow along the first fluid pathway, and a closed position, in which the poppet blocks fluid flow along the first fluid pathway
Implementation Method 2
a spring may be positioned between the poppet and a distal end of the orifice piece to bias the poppet toward the open position
Implementation Method 3
Shock assemblies are used in numerous different vehicles, devices, or the like and configurations to absorb some or all of a movement that is received at a first portion of a vehicle, device, or the like before it is transmitted to a second portion
Data Source
AI summary
A live valve poppet is disclosed. The system includes an active valve to enable or prevent fluid flow in a first flowpath between a damping chamber and a reservoir. A second fluid pathway between the damping chamber and the external reservoir, wherein the second fluid pathway is larger than the first fluid pathway, and a poppet disposed within the second fluid pathway. The poppet distinctly separate from the active valve. The closing of the active valve causes a buildup of fluid pressure that acts against a portion of the poppet to cause the poppet to close a fluid flow through the second fluid pathway.
