Solution Overview

Problem

Conventional dust suppression methods, such as water trucks, are inefficient, costly, and pose safety hazards due to the need for additional labor, fuel consumption, and excessive water usage, while failing to effectively control dust emissions at the source during construction activities.

Innovation Solution

A bucket with a dust suppressing apparatus that integrates a manifold with nozzles to directly apply water at the source of dust creation, reducing emissions by using less water and eliminating the need for additional labor and equipment, with the apparatus being adaptable to various types of machinery and adjustable for optimal spray direction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If water trucks are used to suppress dust emissions, then dust control is achieved, but water consumption increases significantly

Engineering Contradiction:

Improvedust emissionsVSAvoidwater consumption

Core Design Contradiction:

Object-affected harmful factorsVSQuantity of substance

Solution Approach 1:

The patent applies local quality by positioning water spray nozzles directly at the dust generation source (the bucket) rather than using general area spraying. This localized application of water suppresses dust emissions precisely where they occur, reducing the overall water consumption compared to widespread area spraying by water trucks.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The dust suppression system activates before dust becomes airborne by spraying water on the material while it is still in the bucket during the digging and lifting process. This preliminary action prevents dust formation rather than addressing it after it has been generated, improving suppression efficiency and reducing water requirements.

Inventive Principle:

Principle #10Preliminary action

2Object-affected harmful factors

If water trucks with laborers are deployed, then dust suppression is provided, but operational cost increases

Engineering Contradiction:

Improvedust emissionsVSAvoidoperational efficiency

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

The patent merges the dust suppression function with the existing bucket assembly by integrating nozzles and water delivery systems directly onto the bucket. This combination eliminates the need for separate water trucks and laborers, reducing operational costs while maintaining dust suppression effectiveness.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The bucket-mounted dust suppression system operates automatically as part of the bucket's normal operation, requiring no additional labor for manual spraying. The system serves itself by utilizing the bucket's movement and position to deliver water precisely where needed, improving operational efficiency.

Inventive Principle:

Principle #25Self-service

3Object-affected harmful factors

If multiple pieces of equipment are used for dust control, then dust emissions are controlled, but device complexity increases

Engineering Contradiction:

Improvedust emissionsVSAvoidequipment configuration

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent combines multiple functions (material handling and dust suppression) into a single integrated bucket assembly. By mounting nozzles and water delivery components directly on the bucket, the system eliminates the need for separate water trucks, hoses, and manual spraying equipment, thereby reducing overall device complexity.

Inventive Principle:

Principle #5Merging (Combining)

4Area of stationary object

If water is sprayed from distance by water trucks, then dust coverage area is increased, but spray precision decreases

Engineering Contradiction:

Improvedust coverage areaVSAvoidspray direction precision

Core Design Contradiction:

Solution Approach 1:

Inventive Principle:

Principle #3Local quality
