Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of assembly operations and increased number of parts in conventional cylinder drive apparatuses for fluid pressure cylinders due to extensive piping requirements for switching, check, and throttle valves.
Innovation Solution
A cylinder drive manifold device with integrated switching, check, and throttle valves within a block-shaped manifold, reducing the need for external piping and allowing efficient fluid flow management between cylinder chambers, featuring linear fluid paths and variable throttle valves for adjustable flow rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If valve members are connected mutually to one another by pipes, then the cylinder drive apparatus can function properly, but the number of parts increases and assembly operation becomes complicated
Solution Approach 1:
The patent integrates multiple valve members (switching valves, check valves, and throttle valves) into a single manifold body, eliminating the need for separate pipes to connect them. This merging of previously separate components into one integrated unit directly reduces the number of parts and simplifies assembly operations while maintaining all necessary functional connections between valves.
Solution Approach 2:
The manifold serves multiple functions simultaneously: it acts as a distribution chamber for fluid, provides mounting structures for multiple valve members, and creates internal flow paths that replace external piping. This multi-functionality consolidates what would otherwise require separate components and connections, thereby reducing overall system complexity.
2Adaptability or versatility
If multiple separate valves are used for switching, check, and throttle functions, then each function can be independently controlled, but the number of parts increases
Solution Approach 1:
Multiple valve members with different functions (switching, check, and throttle valves) are combined within a single manifold assembly. Each valve member retains its independent control capability while being physically integrated into one unit, thus reducing the total number of separate parts without sacrificing functional independence.
Solution Approach 2:
The manifold structure provides a universal platform that accommodates multiple types of valve members, each performing specific functions. The manifold itself serves as both a structural support and a fluid distribution system, eliminating the need for separate piping infrastructure that would otherwise be required to connect multiple independent valves.
