Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a demand to suppress the increase in cost of shock absorbers.
Innovation Solution
A shock absorber design featuring a cylinder with an inner chamber partitioned into first and second chambers by a cage body, including passages and valves that are adjusted by discs to control fluid communication, reducing the need for additional components and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of valve bodies are used to achieve different valve opening characteristics, then the valve opening characteristics can be varied, but the manufacturing and management costs increase
Solution Approach 1:
The valve assembly is segmented into a standardized cage body and interchangeable valve discs. Each valve disc has different communication hole patterns that create different flow path areas, allowing multiple valve opening characteristics to be achieved by simply changing the valve disc rather than the entire valve body, thereby reducing manufacturing costs.
Solution Approach 2:
A single standardized cage body design serves multiple functions by accommodating different valve discs with various communication hole configurations. This universal cage body can work with any valve disc type, eliminating the need to manufacture multiple specialized valve bodies for different valve opening characteristics.
2Adaptability or versatility
If multiple types of valve bodies are used to achieve different valve opening characteristics, then the valve opening characteristics can be varied, but the management complexity increases
Solution Approach 1:
By segmenting the valve assembly into a standardized cage body and interchangeable valve discs, the system simplifies management. Only the valve discs need to be managed and stored in different configurations, while the cage body remains uniform, significantly reducing the complexity of inventory management and assembly procedures.
Solution Approach 2:
The universal cage body design means that only one type of cage body needs to be managed, maintained, and assembled. The simplicity of having a single cage body type combined with various valve discs reduces the overall device complexity and eases management compared to having multiple specialized valve body types.

AI summary
This shock absorber includes a cylinder having an inner chamber; a cage body partitioning the inner chamber into first and second chambers, and includes a first passage allowing communication between the first and second chambers, a first seat part, a second passage allowing communication between the first and second chambers, and a second seat part. A first valve which is a first valve coming into contact with the first seat part to close the first passage and being separated from the first seat part to open the first passage, and in which a communication hole communicating with the second passage is formed. A second valve comes into contact with the second seat part to close the second passage and is separated from the second seat part to open the second passage. A passage adjusting disc is provided between the first valve and the cage body.
