Solution Overview

Problem

Dust control systems in tissue, towel, and paper manufacturing often fail to effectively manage airborne dust in areas where dust hoods are not easily removable or repositionable, leading to worker safety risks and equipment maintenance issues due to frequent access requirements.

Innovation Solution

A dust hood system comprising a first and second hood body that can be selectively moved between assembled and disassembled positions, using a securing device such as a quick opening clamp to facilitate easy assembly and disassembly, allowing for fluid communication between the hood bodies and enabling independent rotation for access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dust hoods are made fixed and permanently installed, then dust control effectiveness is improved, but worker access and equipment maintenance become difficult

Engineering Contradiction:
Improvedust control effectivenessVSAvoidworker access
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The dust hood is divided into multiple modular sections that can be independently positioned and secured. Each section can be attached or detached without moving the entire hood structure, enabling workers to access specific areas while maintaining dust control in other zones.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The dust hood incorporates movable and adjustable components that allow dynamic reconfiguration. The hood sections can be moved to different positions and secured using quick-connect mechanisms, transitioning between a fixed dust-containing state and an accessible state as needed.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If dust hoods are made removable and repositionable, then worker access and maintenance become easy, but dust control effectiveness deteriorates

Engineering Contradiction:
Improveworker accessVSAvoiddust control effectiveness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

By segmenting the hood into modular sections with standardized connection interfaces, the system maintains structural integrity and sealing effectiveness even when individual sections are removed or repositioned. Each section independently contributes to dust containment when assembled.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hood sections are pre-equipped with connection mechanisms and sealing interfaces that ensure proper alignment and secure attachment. This preliminary preparation enables workers to quickly assemble or disassemble sections without compromising the dust-tight seal when the hood is in its operational configured state.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If dust hoods are made fixed, then dust containment is improved, but frequency of cleaning and maintenance increases

Engineering Contradiction:
Improvedust containmentVSAvoidmaintenance frequency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The modular segmented design allows specific sections that accumulate dust to be independently removed for cleaning while other sections remain in place and continue providing dust containment. This eliminates the need to disassemble the entire hood structure for routine maintenance.

Inventive Principle:
Principle #1Segmentation

4Ease of operation

If dust hoods are made modular and movable, then ease of repositioning is improved, but structural stability deteriorates

Engineering Contradiction:
Improveease of repositioningVSAvoidstructural stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The modular architecture with standardized connection interfaces provides both movability and stability. When sections are assembled together with the connection mechanisms engaged, the structure achieves sufficient rigidity and stability for dust containment, while individual sections remain easy to detach and reposition.

Inventive Principle:
Principle #1Segmentation

AI summary

A dust hood for a dust control system includes a first hood body and a second hood body. The first hood body and the second hood body are each selectively movable between an assembled position and a disassembled position. In the assembled position, the first hood body is adjacent to the second hood body. In the disassembled position, the first hood body is spaced apart from the second hood body.
