Solution Overview

Problem

Existing liquid filtering devices often experience unexpected overflow and turbulence during filling, leading to contamination and inefficiencies in fluid handling.

Innovation Solution

A filtering device with a conical bottom and ribs that direct fluid jets radially through recesses in the lateral surface, reducing turbulence and increasing flow rate, while also being securely fixed to the tank to prevent overflow and splashing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional filtering device is used during filling, then the device structure is simple, but the liquid overflows unexpectedly and causes contamination

Engineering Contradiction:
Improveoverflow preventionVSAvoiddevice structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The device is divided into multiple functional elements: a conical bottom section with ribs for flow direction, a cylindrical upper section with recesses for discharge, and a closing element with sealing. This segmentation allows each part to perform its specific function efficiently while maintaining overall simplicity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The conical bottom introduces a dimensional transition from point-like inlet to radial flow distribution. The ribs extend in the radial direction to guide flow, and recesses are positioned at different heights to control discharge timing, adding spatial dimensions to flow management

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If liquid is filled quickly into the device, then the filling speed increases, but turbulence and bubble formation increase

Engineering Contradiction:
Improvefilling speedVSAvoidturbulence and bubbles
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The conical bottom with curved surfaces and radially arranged ribs guides the liquid flow smoothly from the inlet through the conical section to the discharge recesses. The curved geometry naturally directs flow without creating sharp eddies or turbulence, even at high filling speeds

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

Different sections of the device have specialized functions: the conical bottom with ribs handles high-speed flow direction, the recesses in the cylindrical section control discharge timing and location, and the closing element provides sealing. Each local region is optimized for its specific flow management task

Inventive Principle:
Principle #3Local quality

3Stability of the object's composition

If the device has a closed bottom with ribs, then the flow homogeneity improves, but the device complexity increases

Engineering Contradiction:
Improveflow homogeneityVSAvoidinternal structure
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The conical bottom with its curved surface and radially extending ribs creates natural flow channels that distribute liquid uniformly. The geometry itself performs the flow homogenization function without requiring additional complex internal structures or moving parts

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The conical bottom with ribs serves multiple functions simultaneously: it directs flow radially outward, distributes liquid uniformly across the discharge perimeter, and prevents dead zones where bubbles could form. This multi-functionality achieves flow homogeneity without adding device complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)
