Solution Overview

Problem

Conventional conveyor belt dust collection systems require manual emptying of waste bins and mixing systems need manual transportation of mixed materials, leading to inefficiencies in production time and process flow.

Innovation Solution

A particulate collection system utilizing a chute that funnels dust into a stationary and rotating housing with aligned openings, connected to an external vacuum system, which reduces the air volume required for effective particulate removal and allows for continuous collection and transport of mixed materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a conventional waste bin is used in conveyor belt collection systems, then dust can be collected, but the bin must be periodically emptied by manual intervention which reduces productivity

Engineering Contradiction:

Improvecontinuous operation capabilityVSAvoidmanual emptying requirement

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The system uses an automated vacuum mechanism that continuously removes collected dust from the housing without requiring manual intervention. The vacuum system automatically evacuates particulates through openings in the rotating housing, enabling self-emptying operation and continuous productivity.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical emptying process is replaced with an automated vacuum system that uses pneumatic forces to remove dust. The vacuum mechanism substitutes for manual labor, continuously clearing the collection housing and eliminating downtime for emptying operations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If a large open area is used for vacuuming, then particulates can be collected, but the air volume required increases which reduces efficiency

Engineering Contradiction:

Improvevacuuming efficiencyVSAvoidair volume consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The housing is divided into multiple segments with spaced-apart openings distributed around the circumference. This segmentation allows the vacuum system to target specific zones efficiently, reducing the total air volume needed compared to a single large opening while maintaining effective particulate collection across the entire rotation cycle.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The housing rotates dynamically to bring different sections with openings past the vacuum source. This dynamic positioning allows the vacuum system to concentrate airflow on smaller, strategically positioned openings rather than requiring a large static open area, thereby reducing overall air volume consumption while maintaining collection effectiveness.

Inventive Principle:

Principle #15Dynamics

3Productivity

If mixed materials are collected in a bin, then different particulates can be gathered, but the bin must be manually transported which lengthens production time

Engineering Contradiction:

Improvematerial transport speedVSAvoidmanual transport duration

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The manual mechanical transport of mixed materials is replaced with an automated vacuum transport system. The vacuum system continuously moves collected particulates from the housing through conduits to storage containers or processing points, eliminating manual lifting and transport operations and significantly reducing production time.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The vacuum system acts as an intermediary transport mechanism between the collection housing and final storage or processing locations. This intermediary pneumatic transport system eliminates the need for manual handling and direct mechanical transport, streamlining the material movement process and reducing overall production cycle time.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A particulate collection system for use in a production environment. The particulate collection system includes a chute that collects and funnels dust, or other fine particulates, towards an exit opening. Proximal to the exit opening is a hollow stationary enclosure, and a hollow inner rotatable housing positioned inside the hollow stationary enclosure. The hollow stationary enclosure exhibits a first plurality of longitudinal openings, and the hollow inner rotatable housing exhibits a second plurality of spaced-apart openings along a wall of the rotatable housing. As the dust is funneled through the chute, the dust passes through the first plurality of longitudinal openings and the second plurality of spaced-apart openings, wherein the hollow inner rotatable housing temporarily collects the dust. The particulate collection system has a motor that rotates the hollow inner rotatable housing, and an external vacuum system that removes the collected particulates.
