Low-Noise Electromagnetic Valve Assembly for Air Bag Massage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromagnetic valves in pneumatic massage systems produce excessive noise during deflation, leading to increased production costs and a poor user experience due to the large volume required for silencers.
Innovation Solution
A low-noise electromagnetic valve assembly is designed, comprising an electromagnetic valve body, a flow guide piece, and a silencer. The flow guide piece includes air intake, release, and bag interfaces, with the silencer featuring a housing, silencer cotton, and a silencing air outlet to reduce noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a silencer is arranged at each air release interface, then air release noise is reduced, but production cost increases and the volume of the pneumatic massage system becomes too large
Solution Approach 1:
The patent merges multiple air release interfaces into a single common air release interface, and corresponds only one silencer to this common interface. This combining approach reduces the number of silencers from multiple to one, thereby reducing production cost and system volume while still achieving noise reduction functionality.
Solution Approach 2:
The common air release interface serves multiple air bags simultaneously, making it a universal interface that handles deflation for several air bags. This multi-functional design eliminates the need for separate air release interfaces and silencers for each air bag, resolving the contradiction between noise control and system complexity.
2Object-affected harmful factors
If multiple silencers are arranged for multiple air release interfaces, then air release noise is reduced, but the volume of the pneumatic massage system becomes too large
Solution Approach 1:
By combining multiple air release functions into a single common air release interface and using only one silencer, the patent significantly reduces the total volume occupied by silencers in the system. This merging strategy directly addresses the volume issue while maintaining noise control effectiveness.
3Device complexity
If air release interfaces of multiple electromagnetic valves perform deflation together, then system complexity is reduced, but deflation sound becomes too large
Solution Approach 1:
The patent introduces a common air release interface as an intermediary component that collects exhaust air from multiple air bags and directs it through a single silencer. This intermediary structure allows multiple air release operations to occur simultaneously (maintaining low system complexity) while the silencer mediates the noise issue by treating all exhaust air in one controlled location.
