Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-acting hydraulic dampers face issues with unequal volumes in rebound and compression compartments, leading to complex and costly adjustment mechanisms that lack independence and flexibility in damping characteristics.
Innovation Solution
The linear impelled module damper features a hollow cylinder with a piston dividing it into compression and rebound chambers, with a compression extension cylinder and adjustable bleed circuits, allowing for equal volumes and four independent damping adjustments through removable adjustment modules and valving systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the piston rod is connected to the piston through the rebound chamber, then the damper structure is compact, but the rebound chamber volume becomes significantly smaller than the compression chamber volume
Solution Approach 1:
The invention divides the damper into separate compression and rebound chambers with equal volumes by positioning the piston rod to extend through the compression chamber rather than the rebound chamber. This segmentation allows each chamber to be independently sized and configured, resolving the volume inequality problem while maintaining structural compactness.
2Adaptability or versatility
If adjustable damping mechanisms are added to change fluid flow rates, then damping characteristics can be adjusted for varying conditions, but the structural complexity and fabrication costs increase
Solution Approach 1:
The invention implements adjustable damping characteristics through dynamic valve mechanisms that can change the fluid flow rates between compression and rebound chambers. These valves allow the damping properties to be adjusted for different operating conditions while maintaining a relatively simple overall structure, balancing adaptability with complexity.
3Adaptability or versatility
If four independent damping adjustments are provided for high and low speed compression and rebound, then precise control over damping characteristics is achieved, but the number of components and adjustment mechanisms increases
Solution Approach 1:
The invention combines multiple damping adjustment functions into integrated valve assemblies that control both compression and rebound damping. By merging related adjustment mechanisms and using common structural elements, the patent achieves four independent damping adjustments while reducing the total number of separate components and simplifying fabrication and assembly processes.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enables precise control over damping characteristics by equalizing chamber volumes and providing four independent adjustments, enhancing the damper's ability to accommodate varying conditions without the need for structurally complex components, thus reducing fabrication and assembly costs.
Implementation Method 1
When the piston is moved within the hollow cylinder, valving within the cylinder and piston may permit fluid to flow between the compression and rebound compartments (depending on the direction). The flow of the hydraulic fluid between these two compartments is known as the compression bleed circuit and the rebound bleed circuit, respectively.
Implementation Method 2
Dual-acting hydraulic dampers, also known as shock absorbers, may be utilized to damp the external forces applied to a vehicle, like an automobile.

AI summary
A linear impelled module damper includes a hollow cylinder having an inner body, an outer body, and a channel between the inner and outer body. The hollow cylinder has a sealed first end and a sealed second end. A piston movable within the hollow cylinder divides the hollow cylinder into a compression chamber and a rebound chamber. The channel communicates with the rebound chamber through at least one hole in the rebound chamber. A compression extension cylinder is rigidly fixed to the hollow cylinder approximate to the sealed second end on one end, and having a compression mount attached to the other end. The compression extension cylinder including an air valve being adapted to allow a piston rod to move in and out of the compression extension cylinder. The piston rod including a rebound mount on one end and extending into the compression extension cylinder on the other.
