Staged Softening Gas Shock with Nested Spring-Plugs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable gas shocks for vehicle suspensions do not provide sufficient customizable and staged softening mechanisms to effectively cushion bumps, limiting ride comfort and adjustability.
Innovation Solution
The adjustable gas shock features a staged softening system with a gas piston assembly, including a piston shaft and side opening hollow, both with spring-biased plugs and air passages, allowing for customizable airflow and pressure distribution between upper and lower chambers to provide nonlinear cushioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing adjustable gas shocks are used, then basic suspension function is provided, but sufficient customizable and staged softening mechanisms are not provided
Solution Approach 1:
The gas shock is divided into multiple functional segments: a first softening system with a first plug and first spring, and a second softening system with a second plug and second spring. Each segment operates independently to provide different stages of softening, allowing customizable ride comfort without requiring a complete redesign of the shock assembly.
Solution Approach 2:
The first and second plugs are nested within the piston structure, with each plug positioned in its own hollow cavity. The springs are nested within the plugs, creating a compact multi-layered configuration that provides multiple softening stages within a single integrated component, minimizing space requirements while enhancing adaptability.
2Ease of operation
If single-stage softening is used, then simple structure is maintained, but ride comfort on varied terrain is limited
Solution Approach 1:
The softening system transitions from a static single-stage design to a dynamic multi-stage system. The first and second springs have different spring rates, and the plugs are positioned to engage at different compression stages, allowing the shock to automatically adapt its softening characteristics based on the terrain conditions and impact force.
Solution Approach 2:
The system changes the softening parameter by engaging different spring-plug combinations at different compression stages. The first spring and first plug provide initial softening, while the second spring and second plug provide additional softening at higher compression levels, creating a progressive multi-stage softening effect that enhances ride comfort.

Implementation Method 1
The side opening plug is spring biased by a side opening plug spring formed as a coil spring. The piston shaft plug is spring biased by a piston shaft plug spring formed as a coil spring.
Implementation Method 2
The air piston moves in response to vibrations.
Implementation Method 3
A piston hollow is formed on the frame and the gas piston is glidingly installed in the piston hollow defining an upper air chamber above the piston and a lower air chamber below the piston.
