Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the shock absorber uses traditional design with separate components for damping adjustment, then the damping can be adjusted for different road conditions, but the shock absorber has many parts, low integration, and large volume
Solution Approach 1:
The patent integrates the damping adjustment mechanism into the existing shock absorber structure by combining the flow regulating valve and pilot valve into a unified valve assembly. The air channel is integrated within the valve core, eliminating the need for separate adjustment mechanisms and reducing the total number of parts while maintaining adaptability for different road conditions.
Solution Approach 2:
The valve core serves multiple functions: it acts as both the flow regulating valve body and contains the integrated air channel for damping adjustment. This multi-functional design allows the same component to provide both fluid flow regulation and adjustable damping control, reducing the number of separate parts needed.
2Manufacturing precision
If the shock absorber uses traditional design with separate components, then each component can be optimized independently, but the assembly process becomes difficult and machining costs increase
Solution Approach 1:
By merging the air channel into the valve core structure, the patent reduces the number of assembly steps. The integrated design eliminates the need to assemble separate air channel components with the valve body, simplifying the assembly process while maintaining the ability to optimize the valve core design for manufacturing precision.
3Ease of manufacture
If the shock absorber uses traditional design with multiple separate components, then each component can be manufactured independently, but the shock absorber has low space utilization rate and large volume
Solution Approach 1:
The air channel is nested within the valve core structure, utilizing the internal space of the valve core for the air passage. This nested design allows the air channel to occupy space that would otherwise be empty or unused in the valve assembly, improving space utilization and reducing the overall volume of the shock absorber.
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
The design achieves high integration, easy assembly, and low machining costs, while providing adaptable damping for varying road conditions, enhancing vehicle stability and reducing vibration.
Implementation Method 1
When the valve core moves, the flow regulating valve is controlled by the pilot valve, so as to regulate a flow rate of a fluid between the compression chamber and the rebound chamber
Implementation Method 2
The first one-way valve is arranged in the first air channel, configuring gas to flow only from the first air channel towards the flow regulating valve. The second one-way valve is arranged in the second air channel, configuring the gas to flow from the second air channel away from the flow regulating valve
Implementation Method 3
a first spring and a second spring, respectively, to push the valve core
