Solution Overview

Problem

The complexity of assembly operations and increased number of parts in cylinder drive apparatuses for fluid pressure cylinders due to numerous pipes connecting switching, check, and throttle valves complicates the integration of multiple fluid pressure cylinders.

Innovation Solution

A cylinder drive manifold device with a block-shaped manifold incorporating switching, check, and throttle valves directly into its holes, eliminating the need for connecting pipes between these valves and reducing the overall number of parts, allowing for easier assembly and efficient fluid flow management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple pipes are used to connect switching valves, check valves, and throttle valves, then the fluid flow paths can be established, but the number of parts increases and assembly operation becomes complicated

Engineering Contradiction:
Improvefluid flow path establishmentVSAvoidnumber of parts and assembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates multiple valve components (switching valves, check valves, and throttle valves) and their connecting pipes into a single integrated manifold device. This merging eliminates the need for separate pipes to connect these valves, thereby reducing the total number of parts and simplifying assembly operations while maintaining reliable fluid flow paths between all components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The manifold device serves multiple functions simultaneously: it acts as a distribution manifold for fluid flow, houses switching valves for flow control, incorporates check valves for one-way flow protection, and integrates throttle valves for flow rate regulation. This multi-functionality consolidates what would otherwise require separate components and connections into a single unified device.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a plurality of fluid pressure cylinders are driven using separate valve assemblies, then each cylinder can be controlled independently, but the overall system requires numerous connecting pipes and becomes difficult to assemble

Engineering Contradiction:
Improveindependent cylinder controlVSAvoidassembly operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent combines multiple independent valve assemblies into a single integrated manifold that can control multiple fluid pressure cylinders. Each cylinder maintains independent control through dedicated valve circuits within the manifold, but the physical assembly is simplified because all valves and connecting passages are pre-integrated into one unit that can be mounted as a single component.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If numerous pipes are used to connect various valves, then complete fluid circulation is achieved, but the assembly operation becomes complicated and time-consuming

Engineering Contradiction:
Improvefluid circulationVSAvoidassembly operation speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent merges all valve components and their interconnecting pipes into a single integrated manifold assembly. This eliminates the need for on-site pipe installation and connection between separate valve units, allowing the entire fluid circulation system to be assembled by mounting the pre-integrated manifold unit, thereby dramatically improving assembly productivity while maintaining complete fluid circulation capability.

Inventive Principle:
Principle #5Merging (Combining)
