Solution Overview

Problem

Dust collection systems face inefficiencies due to fluid resistance caused by movable elements, which limits dust collection efficiency and requires optimization of two-dimensional arrangements to minimize resistance.

Innovation Solution

A dust collection system with a flow path control device using a partition wall to separate cavities, allowing gas flows to avoid interference from movable elements, thereby reducing fluid resistance and enhancing efficiency, and includes features like a heating member to handle solidified dust and sensors for pressure and area control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple movable elements are provided to increase dust collection area, then dust collection effectiveness is improved, but fluid resistance significantly increases

Engineering Contradiction:
Improvedust collection effectivenessVSAvoidfluid resistance
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The housing cavity is segmented into a first cavity containing movable elements and a second cavity for gas flow, separated by a partition wall. This segmentation allows movable elements to be isolated from the main gas flow path, enabling multiple movable elements to be used for effective dust collection while preventing them from creating fluid resistance in the gas flow path.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The partition wall acts as an intermediary structure that separates the functional zones: it allows the movable elements to perform dust collection in the first cavity while preventing gas flow interference, thus enabling both high dust collection effectiveness and low fluid resistance simultaneously.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of energy

If movable elements are positioned to optimize two-dimensional arrangement, then fluid resistance is reduced, but device complexity increases

Engineering Contradiction:
Improvefluid resistanceVSAvoidarrangement optimization complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The partition wall introduces a spatial dimension that completely separates the movable element arrangement space from the gas flow path. Instead of optimizing two-dimensional arrangements to minimize interference, the solution moves to three-dimensional separation, where the partition wall creates distinct layers for different functions, greatly simplifying the design process.

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