Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electromagnetic valve manifolds face issues with voltage drop and increased size due to sequential power delivery to electromagnetic valves, leading to potential malfunctions and the need for additional connectors as the number of valves increases.
Innovation Solution
The electromagnetic valve manifold design includes a slave station and valve driving units connected by cables, allowing simultaneous power and control signal delivery to each valve assembly, reducing voltage drop and eliminating the need for additional connectors, while a passage sealing unit ensures stable operation and versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electromagnetic valve power is sequentially delivered from the valve assembly closest to the slave station, then the electrical connection structure is simplified, but the voltage of electromagnetic valve power drops and malfunctions occur more easily for valve assemblies farther from the slave station
Solution Approach 1:
The patent divides the power supply system into multiple independent power supply units, each responsible for a specific valve assembly. Each power supply unit includes a power supply circuit and control circuit that independently provide power and control signals to its corresponding valve assembly, eliminating the sequential power delivery chain and ensuring stable voltage regardless of distance from the slave station.
2Device complexity
If valve assemblies are electrically connected in a row, then the control structure is simplified, but the connector size and manifold size increase as the number of electromagnetic valves increases
Solution Approach 1:
The patent segments the electrical connection system into multiple independent connection units, where each power supply unit connects to its corresponding valve assembly through dedicated wiring. This eliminates the need for a single large connector that would require increasing numbers of output points, thereby reducing connector size and overall manifold volume while maintaining simplified control structure.
3Adaptability or versatility
If the number of electromagnetic valves is increased, then the valve manifold functionality is enhanced, but additional connectors are required which increases the manifold size
Solution Approach 1:
The patent employs a modular architecture where the manifold is divided into multiple valve assemblies, each with its own dedicated power supply unit. This segmentation allows the system to accommodate any number of valves by simply adding or removing complete modular units rather than expanding existing connectors, thus enhancing versatility without proportionally increasing manifold size.
Solution Approach 2:
Each power supply unit is designed as a universal module that can serve any valve assembly regardless of the total number of valves in the system. This multi-functional design allows the same hardware configuration to adapt to different valve counts, eliminating the need for custom connectors for each configuration and reducing overall system size.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design stabilizes the operation of electromagnetic valves by maintaining power integrity and reducing the overall size of the manifold, enhancing versatility and preventing voltage drops, even with increased valve counts.
Implementation Method 1
The slave station output port and one of the valve driving units closest to the slave station are electrically connected to each other by a first cable. Adjacent ones of the valve driving units in the single direction are electrically connected to each other by a second cable configured to deliver the control signal and the valve driving unit power
Implementation Method 2
The electromagnetic valve power is used to drive each of the electromagnetic valves of a corresponding one of the valve assemblies

AI summary
An electromagnetic valve manifold includes valve assemblies arranged in a single direction, each valve assembly including electromagnetic valves arranged in the single direction, a slave station disposed at one of ends of the electromagnetic valve manifold in the single direction, and a valve driving unit disposed in correspondence with each of the valve assemblies. The slave station includes a slave station output port that sends a control signal and valve driving unit power to the valve driving units. The valve driving units each include an electromagnetic valve power input port that receives electromagnetic valve power from an external device and a circuit board configured to control driving of the electromagnetic valves of a corresponding one of the valve assemblies using the control signal and send the electromagnetic valve power to the electromagnetic valves.
