Solution Overview

Problem

Conventional fugitive dust suppression systems on construction sites fail to accurately direct mist spray injections to the impact point of crushing machines, leading to ineffective dust suppression and excessive water consumption, causing environmental pollution.

Innovation Solution

A sensor-based motion control system that uses a laser pointer and data logger to determine the impact point of a crushing machine, controlling the vertical and horizontal motion of a blast pipe to align mist spray nozzles precisely with the impact point, minimizing dust scattering and water usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If conventional water spray methods are used with manual operation, then dust suppression can be attempted, but the worker's safety is compromised and water consumption is excessive

Engineering Contradiction:
Improvedust suppression effectivenessVSAvoidworker safety
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The system enables self-service operation through automatic detection and control. The sensor detects the crusher's position and the controller automatically adjusts the blast pipe orientation and water spray activation, eliminating the need for manual operation and ensuring worker safety while maintaining dust suppression effectiveness

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual mechanical operation of water spraying is replaced with an automated sensor-based control system. The sensor detects crusher position, the controller processes this information, and automatically actuates the blast pipe and water spray system, replacing manual labor with an automated electromechanical system

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Object-affected harmful factors

If mist spray is injected in a wide range using conventional systems, then dust suppression coverage is increased, but water consumption increases unnecessarily

Engineering Contradiction:
Improvedust suppression coverageVSAvoidwater consumption
Core Design Contradiction:
Object-affected harmful factorsVSLoss of substance

Solution Approach 1:

The system applies local quality by directing water spray precisely to the local area where dust is generated. The sensor detects the crusher's impact position and the controller orientates the blast pipe to spray water only at that specific location, rather than spraying in a wide range, thus reducing water consumption while maintaining effective dust suppression coverage

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system uses feedback from the sensor that continuously monitors the crusher's position. This feedback information is processed by the controller which adjusts the blast pipe orientation and water spray activation in real-time, ensuring water is sprayed only when and where needed, thereby reducing unnecessary water consumption while maintaining effective dust suppression

Inventive Principle:
Principle #23Feedback

3Object-affected harmful factors

If manual adjustment of mist spray direction is used, then some dust suppression is achieved, but the injection directions do not correspond to the hitting impact point in real-time

Engineering Contradiction:
Improvedust suppressionVSAvoidspray direction accuracy
Core Design Contradiction:
Object-affected harmful factorsVSMeasurement precision

Solution Approach 1:

Manual adjustment of spray direction is replaced with an automated sensor-based positioning system. The sensor precisely detects the crusher's hitting impact point coordinates, and the controller automatically orientates the blast pipe to match this position in real-time, achieving high measurement precision and accurate spray direction alignment without manual intervention

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system performs self-adjustment of spray direction based on sensor input. The controller automatically calculates the required blast pipe orientation angles and actuates the positioning mechanism to align the spray direction with the crusher's impact point, enabling real-time accurate tracking without external manual control

Inventive Principle:
Principle #25Self-service
