Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drainage devices for cleaning heads in paper manufacturing plants face issues with clogging due to dirt particles and wastewater settling on walls, requiring manual cleaning and disrupting the drainage process.
Innovation Solution
A drainage device with an air-water separation container connected to the cleaning head, allowing for air and wastewater separation close to the cleaning head, preventing particles from drying out and clogging, and featuring a tubular body with propellant inlets to generate acceleration and helical flow, ensuring continuous wetting and efficient transport of debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a stationary collecting container is used across the drying wire, then the drainage structure is simple, but the cleaning head must traverse a long distance causing dirt to settle and clog the device
Solution Approach 1:
The patent applies the dynamics principle by making the air-water separation container movable rather than stationary. The container is connected to the cleaning head via a tubular body and moves together with the cleaning head transversely across the drying wire. This dynamic configuration ensures that the separation container is always positioned close to the cleaning head, maintaining effective drainage function without requiring a long traversal path that would cause clogging.
Solution Approach 2:
The patent applies the nested doll principle by integrating the air-water separation container within the movable assembly of the cleaning head system. The separation container is connected to the cleaning head and moves together with it, effectively nesting the separation function within the cleaning operation. This integration ensures that the separation container remains close to the source of dirt and water without requiring a separate stationary structure.
2Device complexity
If the air-water separation container is stationary, then the structure is simpler, but the cleaning head must travel a long distance causing dirt particles to dry out and cake
Solution Approach 1:
The patent applies the dynamics principle by making the air-water separation container movable rather than stationary. The container is connected to the cleaning head via a tubular body and moves together with the cleaning head transversely across the drying wire. This dynamic configuration ensures that the separation container is always positioned close to the cleaning head, maintaining effective drainage function without requiring a long traversal path that would cause clogging.
Solution Approach 2:
The patent applies the skipping principle by enabling the separation container to rapidly move with the cleaning head across the drying wire. This rapid movement allows the system to complete the drainage and separation process quickly, preventing dirt particles from having time to dry out and cake on the container walls during the traversal.
3Device complexity
If the cleaning head moves across a long distance to reach the drainage container, then the drainage container can be stationary, but the drainage quality becomes non-uniform
Solution Approach 1:
The patent applies the dynamics principle by making the air-water separation container movable rather than stationary. The container is connected to the cleaning head via a tubular body and moves together with the cleaning head transversely across the drying wire. This dynamic configuration ensures that the separation container is always positioned close to the cleaning head, maintaining effective drainage function without requiring a long traversal path that would cause clogging.
