Reverse Inlet Cartridge Seat With Circumferential High-Flow Passage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reverse water inlet cartridges face issues with reduced flow due to limitations in cartridge base inlet port positioning and compatibility with conventional ceramic disk hole positions, leading to compression and reduced flow rates.
Innovation Solution
A high-flow reverse water inlet cartridge seat with a seat body featuring a substrate and cylindrical wall, triangularly configured inlet and outlet holes, and a circular waterflow passage between inlet enclosing frames, increasing the cross-sectional area of the flow path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional reverse water inlet cartridge structure is used to achieve flow path redirection, then the inlet and outlet holes can be positioned to reverse flow direction, but the cross-sectional area of the flow path is reduced leading to compression and reduction in flow rates
Solution Approach 1:
The patent introduces a circular waterflow passage that adds a radial dimension to the flow path, allowing water to flow circumferentially around the central axis rather than being constrained to a linear path. This dimensional change significantly increases the cross-sectional area available for flow while maintaining the reverse flow direction function.
Solution Approach 2:
The waterflow passage is segmented into multiple flow channels: a central passage and circumferential passages. This segmentation allows water to travel through multiple parallel paths simultaneously, effectively increasing the total flow capacity while maintaining the reverse flow direction from inlet to outlet holes.
2Adaptability or versatility
If the cartridge base inlet port position is constrained to maintain compatibility with conventional ceramic disk hole positions, then compatibility is achieved, but the flow path becomes compressed and flow rates are reduced
Solution Approach 1:
By transitioning from a planar flow path to a three-dimensional circular waterflow passage with both central and circumferential components, the invention increases the cross-sectional area available for flow. This allows the cartridge to maintain compatibility with conventional ceramic disk hole positions while avoiding flow path compression through the expanded flow geometry.

AI summary
A reverse water inlet cartridge seat has a seat body with a substrate and a cylindrical wall formed around the substrate, a pair of inlet holes and an outlet hole extending through the substrate, a pair of inlet enclosing frames protruding through a top surface of the seat body, and a circular waterflow passage formed between the pair of inlet enclosing frames and the cylindrical wall of the seat body so as to form a circumferential passage. The cylindrical wall protrudes from the top surface of the substrate.
