Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Essential oil solenoid valves face issues with clogging and leakage due to dust accumulation in air holes and tubes, leading to unreliable air intake.
Innovation Solution
A bottle solenoid valve design featuring a ventilation channel on the bottle cap that communicates with the atmosphere, preventing dust accumulation and ensuring stable air flow, combined with a valve core assembly and coil assembly for controlling fluid flow, and an antiskid structure for easy assembly and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If air holes and tubes are used for air intake, then the structure is simple, but dust accumulation causes clogging and leakage
Solution Approach 1:
The patent introduces a bottle cap as an intermediary component between the external environment and the air intake system. The bottle cap includes a ventilation channel that allows air to pass through while filtering out dust and contaminants. This intermediary structure resolves the contradiction by maintaining simple air intake functionality while preventing dust accumulation that would cause clogging and leakage.
2Device complexity
If traditional air intake structures are used, then device complexity is low, but clogging occurs due to dust accumulation
Solution Approach 1:
The patent segments the air intake function into two distinct parts: the ventilation channel in the bottle cap for dust-free air intake, and the original air holes/tubes for airflow control. By separating the filtration function (ventilation channel) from the flow control function (air holes), the system prevents dust accumulation in the airflow paths while maintaining simple device complexity.
3Loss of substance
If the bottle cap is tightly sealed, then fluid loss is prevented, but pressure balance is disrupted
Solution Approach 1:
The patent incorporates a ventilation channel in the bottle cap that provides preliminary air intake before the main fluid flow occurs. This preliminary action of allowing air through the ventilation channel prevents pressure vacuum formation when the bottle is tilted or used, maintaining pressure balance while the tight seal prevents fluid loss. The ventilation channel is positioned and designed to allow air passage without compromising the seal.
