Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current coolant pump filter mechanisms require frequent maintenance due to clogging from foreign matters, and existing solutions like centrifugal separation are inefficient for small particles and increase energy consumption.
Innovation Solution
A coolant pump design featuring a rotary blade with a specific cross-sectional configuration that generates a speed difference between the blade and the working fluid, creating a turbulent flow to detach foreign matters from the filter surface without rotating the filter, thus reducing clogging and energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a filter element type filter is used to achieve highly precise filtration, then filtration precision is improved, but the filter requires frequent cleaning or replacement due to clogging
Solution Approach 1:
The patent applies preliminary action by introducing a rotary blade that continuously removes foreign matters from the filter surface before they can accumulate and cause clogging. The blade rotates to scrape and detach particles from the filter element, preventing the filter from reaching a clogged state that would require maintenance.
Solution Approach 2:
The patent implements self-service through the automatic cleaning mechanism where the rotary blade, driven by the pump's rotation, continuously cleans the filter element without external intervention. The system cleans itself during normal operation, eliminating the need for separate maintenance activities.
2Loss of time
If a cyclone filter is used to eliminate maintenance needs, then maintenance frequency is reduced, but filtration precision deteriorates and it cannot filter light dust
Solution Approach 1:
The patent merges the advantages of both filter types by combining a filter element (capable of precise filtration) with a rotary blade cleaning mechanism (that prevents clogging). This hybrid approach achieves both high filtration precision and reduced maintenance needs simultaneously.
Solution Approach 2:
The patent changes the operational parameters of the filter system by introducing mechanical rotation and blade scraping action. This transforms the static filtration process into a dynamic system where the blade speed and rotation create forces that detach particles, changing how the filter operates to prevent clogging.
3Object-generated harmful factors
If centrifugal force is used to remove foreign matters from the filter surface, then large particles can be removed, but small particles like dust cannot be effectively removed and energy consumption increases
Solution Approach 1:
The patent uses mechanical vibration through the rotary blade's rotation and contact with the filter surface. The blade's movement creates vibratory forces that detach particles from the filter, providing a more effective and energy-efficient alternative to high-speed centrifugal separation.
Solution Approach 2:
The patent replaces the high-energy centrifugal separation system with a low-energy mechanical blade scraping system. Instead of rotating the entire filter at high speed to generate centrifugal force, a simple blade rotates to mechanically scrape particles off, substituting a high-energy mechanical system with a low-energy one.
Applied Scientific Principles
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 design effectively prevents filter clogging by detaching foreign matters through turbulent flow, reducing maintenance needs and energy consumption, while ensuring clean fluid supply to the pump.
Implementation Method 1
a speed difference is produced between the blade and the working fluid present in the space (G) between the filter (51) and the casing inner wall (3i). In the space (G) between the filter (51) and the casing inner wall (3i), when the rotating blade (61, 61A, 61B, 61C, 61E) proceeds in the working fluid (e.g., a coolant), a turbulent flow is generated behind the blade
Implementation Method 2
a speed difference is produced between the blade and the working fluid present in the space (G) between the filter (51) and the casing inner wall (3i). In the space (G) between the filter (51) and the casing inner wall (3i), when the rotating blade (61, 61A, 61B, 61C, 61E) proceeds in the working fluid (e.g., a coolant), a turbulent flow is generated behind the blade, and a flow that sucks the working fluid from the inside of the filter (51) to the outside of the filter (51) is generated. Foreign matters are detached from the outer peripheral surface of the filter (51) by such the turbulent flow or the flow that sucks the working fluid

AI summary
The present invention is a filter mechanism provided in a pump or the like, and the purpose thereof is to provide a filter mechanism that can eliminate foreign matter adhering to the surface of a filter and thereby can prevent clogging of filters because of foreign matter. According to the present invention, an area toward the inside in the direction of the radius of the filter is linked to an intake opening (235) of the pump (for example, a trochoid pump (22)) and, via the pump (22) to a pump ejection opening (trochoid pump ejection opening (215)), and an area between a filter (5) and (an inside wall surface (3i) of) a first casing (3) is linked to a low-pressure ejection opening (discharge opening (237)) for a working fluid.
