Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In compressed-air drying systems, there is no effective device to collect the liquid drained from both the oil mist separator and the air dryer, leading to inefficiencies and potential operational defects in systems like vehicle brakes and suspensions.
Innovation Solution
A compressed-air drying system that includes a reservoir connected to the drain ports of both the oil mist separator and the air dryer, with a shared drain passage to collect and store the liquid, reducing space and pressure loss by prioritizing the drainage from the oil mist separator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate drainage systems are used for the oil mist separator and air dryer, then each component can be drained independently, but the system complexity and space requirements increase
Solution Approach 1:
The patent combines the drainage systems of the oil mist separator and air dryer into a single integrated drainage manifold. The first drainage line from the oil mist separator and the second drainage line from the air dryer are merged into a common drainage passage that leads to a shared reservoir, reducing system complexity while maintaining independent drainage capability through controlled valves.
Solution Approach 2:
The common drainage manifold serves multiple functions: it collects liquid from both the oil mist separator and air dryer, provides a shared pathway to the reservoir, and enables centralized liquid storage. This multi-functional design eliminates the need for separate drainage systems while preserving independent drainage control.
2Volume of stationary object
If a single reservoir collects liquid from both the oil mist separator and air dryer, then space is reduced and efficiency increases, but liquid from both sources must be managed together
Solution Approach 1:
The patent merges the liquid collection function into a single reservoir that receives drainage from both the oil mist separator and air dryer through a common drainage system. This consolidation reduces the total volume of stationary objects compared to having separate reservoirs, while the drainage manifold manages the combined liquid input.
3Productivity
If drainage lines are extended to connect both components to a common reservoir, then liquid collection is improved, but pressure loss in the drainage system increases
Solution Approach 1:
The patent positions the common reservoir at a lower elevation than both the oil mist separator and air dryer, creating a gravitational potential difference that drives liquid flow toward the reservoir. This gravitational assist reduces the need for extended horizontal drainage lines and minimizes pressure loss in the drainage system.
Solution Approach 2:
The patent utilizes the vertical dimension by positioning the reservoir below the drainage sources, transforming the drainage problem from a horizontal extension issue to a vertical gravity-driven flow system. This dimensional change reduces the length of drainage lines required while maintaining effective liquid collection.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively collects liquid from both the oil mist separator and the air dryer, reducing pressure loss and increasing efficiency in draining liquids, thus preventing operational defects in systems that use compressed air.
Implementation Method 1
When executing a loading mode operation (dehumidification), the above described air dryer removes oil and water from compressed air
Implementation Method 2
The oil separator causes air containing oil and water to strike impingement members to separate gas and liquid from each other
