Pneumatic Solenoid Valve Diffuser for Faster Venting Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pneumatic solenoid valves have limited flow rates due to the clear width of the valve passage and power consumption, which restricts their performance in applications like automatic clutch systems and transmission-control systems, especially during venting, without the ability to increase the valve passage width or power consumption significantly.
Innovation Solution
Incorporating a diffuser within the pneumatic valve apparatus that widens the cross-section of the vent channel transversely to the valve axis, allowing for accelerated air flow and improved flow rates while maintaining a compact design and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the clear width of the valve passage is increased to improve flow rate, then the flow rate increases, but the device size and power consumption increase
Solution Approach 1:
The patent introduces a diffuser channel that runs transversely to the valve axis, creating a new dimensional pathway for air flow. This transverse diffuser channel widens from the vent valve seat to the vent channel, providing an additional flow dimension that increases the effective flow area without increasing the axial length of the valve body.
Solution Approach 2:
The vent channel is segmented into multiple pathways: the original axial vent channel and the new transverse diffuser channel. This segmentation allows compressed air to be distributed through multiple routes, increasing the total flow capacity while maintaining a compact overall valve structure.
2Productivity
If the clear width of the valve passage is increased to improve flow rate, then the flow rate increases, but the power consumption of the actuator increases
Solution Approach 1:
By adding the transverse diffuser channel dimension, the patent creates additional flow capacity without requiring increased actuator force. The diffuser geometry naturally guides the air flow through the transverse channel, achieving higher flow rates with the same actuator power consumption.
3Productivity
If the power consumption of the actuator is increased to improve flow rate, then the flow rate increases, but the device complexity and size increase
Solution Approach 1:
The diffuser channel is merged with the existing vent channel structure, forming an integrated flow path. The diffuser adjoins the vent valve seat and transitions into the vent channel, combining multiple functions (flow distribution, flow acceleration, and venting) into a single integrated component rather than adding separate systems.
4Productivity
If the device size is increased to improve flow rate, then the flow rate increases, but the compact design is compromised
Solution Approach 1:
The transverse diffuser channel utilizes the radial dimension of the valve body rather than extending the axial length. This allows the flow capacity to be increased by utilizing unused spatial dimensions within the existing valve footprint, maintaining compact installation space while achieving higher flow rates.
