Radial Communication Path in Pressure Buffer Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure buffer devices face limitations in size and adjustment range for damping force due to the placement of communication paths close to the center, restricting the size of applying members and the range of damping force that can be set.
Innovation Solution
A pressure buffer device configuration with a pipe-shaped member, a partitioning member, a fluid reservoir portion, and a communication path arranged radially, allowing for increased size selection of applying members and flexibility in setting damping force by positioning the communication path at the outer side of the fluid reservoir portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the communication path is arranged at a position close to the center of the pressure buffer device, then the structure is compact, but the space for arranging the applying member is reduced and the adjustment range of damping force is narrowed
Solution Approach 1:
The communication path is rearranged from a central axial position to an outer radial position, utilizing the radial dimension of the pipe-shaped member. This dimensional shift creates sufficient space for the applying member while maintaining structural compactness, directly resolving the contradiction between space availability and structural complexity.
2Length of moving object
If the communication path is arranged at a position close to the center, then the overall size is reduced, but the size selection range of applying member is limited
Solution Approach 1:
By positioning the communication path at the outer side in the radial direction rather than at the center, the patent utilizes the radial dimension to accommodate larger applying members without increasing the axial length of the device. This allows for a greater size selection range of applying members while keeping the overall device length compact.
3Adaptability or versatility
If the communication path is arranged at the outer side of the fluid reservoir portion, then the flexibility for setting damping force is improved, but the structural complexity increases
Solution Approach 1:
The communication path is positioned at the outer side of the fluid reservoir portion in the radial direction, creating sufficient space for various applying member configurations. This radial arrangement provides flexibility in setting damping force by allowing different sizes and types of applying members to be installed, while the modular outer positioning keeps the added structural complexity manageable.
