Parallel Valve Assembly Modular Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parallel type valve assemblies with multiple electromagnetic valves are cumbersome and require complex installation processes due to the use of a manifold base, limiting flexibility in adjusting the number of valves.
Innovation Solution
A compact valve assembly design where two connected valve units are directly abutted between end blocks with connecting bolts, forming a serial connection without a manifold base, allowing for easy adjustment of the number of electromagnetic valves by using end blocks with power supply and air inlet/discharge ports for efficient electrical and fluid coupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If plural electromagnetic valves are arranged in two rows on a manifold base, then the valve assembly can be formed efficiently, but the overall size becomes large and the installation operation becomes complicated
Solution Approach 1:
The valve assembly is segmented into multiple valve units, each comprising electromagnetic valves arranged in parallel rows between end blocks. Each valve unit can be independently assembled and then connected in series, dividing the complex installation into simpler modular steps.
Solution Approach 2:
Multiple electromagnetic valves are merged into integrated valve units with common end blocks that contain collective air inlet/discharge ports and power supply connectors. This combining reduces the number of separate connections needed compared to individual valve installation.
2Reliability
If a manifold base is used to install electromagnetic valves, then the valves can be fixed, but the number of valves is determined during design and cannot be easily changed
Solution Approach 1:
The valve assembly structure is made dynamic and adjustable through modular valve units connected in series. The number of valve units can be changed by simply adding or removing modules and reconnecting, rather than redesigning a fixed manifold base.
Solution Approach 2:
The end blocks are designed with universal collective ports and connection interfaces that can accommodate different numbers of valve units. The same end block structure serves multiple functions: securing valves, providing collective fluid connections, and enabling series expansion.
3Strength
If electromagnetic valves are individually attached to the manifold base using screws, then secure fixation is achieved, but the installation operation becomes complicated
Solution Approach 1:
The fixation operation is merged into a standardized valve unit assembly process. Multiple valves are pre-fixed to end blocks within each valve unit, and the entire unit is then connected in series, reducing the number of separate fixation operations required.
Solution Approach 2:
The electromagnetic valves are preliminarily assembled and fixed to the end blocks within each valve unit before the final series connection. This preliminary assembly simplifies the overall installation by preparing standardized modules in advance.

AI summary
Two connected valve units each formed by serially connecting plural electromagnetic valves in a direct abutment state are disposed in parallel between two end blocks. The two end blocks are tightened with plural connecting bolts disposed therebetween so as to directly clamp and fix the two connected valve units from both sides in the serial connection direction of the electromagnetic valves. One of the end blocks is provided with a power supply connector, and the other is provided with an air inlet port and a discharge port.
