Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooling circuits require separate components for air venting, particle filtration, and deionization, leading to increased weight, complexity, and maintenance efforts.
Innovation Solution
A filter unit with a deionizing filter material and a filter cage that separates the coolant flow into top and bottom portions, allowing air bubbles to rise and be removed while deionizing and filtering the coolant in a single, integrated unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate components are used for air venting, particle filtration, and deionization, then each function can be performed effectively, but the weight and complexity of the cooling circuit increases
Solution Approach 1:
The patent combines air venting, particle filtration, and deionization functions into a single integrated filter unit. The filter unit includes a filter element for particle filtration and deionization, and a separation space for air bubble removal, all within one component that replaces multiple separate devices in the cooling circuit.
Solution Approach 2:
The filter unit is designed as a multi-functional component that simultaneously performs air venting, particle filtration, and deionization. This universal device handles multiple cooling circuit requirements in one unit, reducing the overall number of components while maintaining all necessary functions.

4Speed
If the cross-sectional area of the inlet is smaller than the top portion, then the flow speed is reduced allowing air bubbles to rise, but the device dimensions increase
Solution Approach 1:
The patent transitions from a uniform cross-section design to a variable cross-section design where the top portion has a larger cross-sectional area than the inlet. This dimensional change creates a expansion space that reduces flow velocity and allows air bubbles to rise, achieving air venting without requiring a completely separate large-volume air separator.
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 filter unit effectively removes air bubbles, particles, and ions from the coolant, reducing the weight and complexity of the cooling circuit, and minimizing maintenance requirements by integrating multiple functions into a single component.
Implementation Method 1
a deionising filter material provided on or in the filter cage and in at least a part of the top portion of the main body
Implementation Method 2
a cross-sectional area of the inlet at the top of the main body is smaller than a cross-sectional area of the top portion of the main body. This allows reducing a flow speed of the liquid coolant from the inlet and entering the interior space of the main body due to the widened cross-sectional area
Implementation Method 3
A reduced flow speed allows air bubbles to rise, for example, rise against a flow of coolant through the inlet and through the main body
