Hydraulic Piston Release Member for Air Venting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hydraulic devices face challenges in effectively removing air from their interior spaces, which can lead to reduced efficiency and performance due to trapped air affecting hydraulic pressure and sealing.
Innovation Solution
The hydraulic device incorporates a release member attached to the hydraulic structure, exposed to both the interior space and atmosphere, which releases air based on internal pressure, utilizing a piston and cylinder bore configuration with seal members to enhance air removal and sealing while allowing for friction application and fluid reservoir management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a release member is added to remove air from the interior space, then air removal capability is improved, but device complexity increases
Solution Approach 1:
The piston is designed to serve multiple functions: it generates hydraulic pressure through movement in the cylinder bore, seals the interior space from the exterior space, and provides a mounting surface for the release member. This multi-functionality allows the release member to be integrated into the existing piston structure rather than requiring a separate dedicated component, thereby improving air removal capability while minimizing the increase in device complexity.
2Reliability
If a seal member is provided between the piston and cylinder bore, then sealing performance is improved, but device complexity increases
Solution Approach 1:
The seal member is extracted as a separate, specialized component that is inserted into a groove on the piston. This allows the sealing function to be performed by a dedicated element rather than requiring the piston itself to be complex or specially shaped. The seal member can be replaced or maintained independently, improving sealing performance while keeping the overall device structure relatively simple.
3Power
If an additional piston and cylinder bore are added, then hydraulic pressure generation is improved, but device complexity increases
Solution Approach 1:
The additional piston and cylinder bore are integrated into the same base member as the first piston, sharing common structural elements such as the base member body and mounting interfaces. This merging approach allows the hydraulic system to generate increased pressure through multiple pistons while avoiding the need for completely separate hydraulic circuits or additional base structures, thereby improving power output while controlling the increase in device complexity.
