Offset Tube Mount Shock Absorber for Extended Stroke and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shock absorbers for motor vehicles often have limited stroke length and stability issues due to the positioning of the tube mount on the central axis, which restricts the range of dampened motion and can lead to unwanted movement and stress on the vehicle's frame.
Innovation Solution
The shock absorber system includes a tube mount offset from the central axis of the shock tube, connected to a stabilization device with adjustable arms that restrict movement perpendicular to the central axis, and a reservoir valve mechanism that opens at high fluid velocity to enhance performance during high-speed scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the tube mount is positioned on the central axis of the shock tube, then the structure is simple and easy to manufacture, but the stroke length is limited and stability issues occur
Solution Approach 1:
The tube mount is deliberately positioned offset from the central axis of the shock tube, creating an asymmetric mounting configuration. This asymmetric placement extends the usable stroke length of the shock absorber and improves stability by preventing unwanted rotation and movement during operation, while still maintaining manufacturing feasibility through standard offset mounting techniques
2Ease of manufacture
If the tube mount is positioned on the central axis, then the mounting structure is simple, but stability and range of motion are reduced
Solution Approach 1:
The offset mounting position creates an asymmetric configuration that inherently improves stability by establishing a more favorable geometric relationship between the shock tube, mount, and vehicle frame, preventing unwanted rotation and movement during operation
Solution Approach 2:
The tube mount is positioned offset from the central axis, utilizing the radial dimension rather than solely the axial dimension. This dimensional change allows the shock absorber to maintain stability while achieving a wider range of motion and preventing contact with vehicle components
3Length of moving object
If the tube mount is offset from the central axis, then stroke length and stability are improved, but the mounting structure becomes more complex
Solution Approach 1:
The offset mounting configuration extends the usable stroke length by utilizing the radial offset position, allowing the shock absorber to travel through a greater range of motion without contacting vehicle components, while the mounting structure remains relatively simple using standard offset mounting techniques
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 configuration increases the usable stroke length, reduces mechanical stress, and stabilizes the tube mount, improving the shock absorber's performance by allowing a wider range of motion and reducing the risk of contact with other vehicle components.
Implementation Method 1
a stabilization device with adjustable arms that restrict movement perpendicular to the central axis
Implementation Method 2
The valve mechanism can be configured to remain in the closed position when a velocity of fluid within the first fluid line is below a threshold velocity. In some embodiments, the valve mechanism transitions to the opened position when the velocity of the fluid within the first fluid line is at or above the threshold velocity.
Implementation Method 3
Shock absorbers are widely used in connection with motor vehicles to reduce shock to vehicles caused by roadway features such as bumps, dips, slopes, potholes, or other irregularities on the roadway.

AI summary
A shock absorber system can includes a shock tube and a piston slidably mated to an end of the shock tube. The system can include a heat sink reservoir. The heat sink reservoir can be connected to the shock tube via a valved fluid connection. The valved fluid connection can limit or permit fluid flow from the shock tube to the heat sink reservoir depending on fluid velocity and/or pressure.
