Solution Overview

Problem

In construction sites, the inefficiency of manual vacuum cleaner allocation and operation hinders productivity due to the time-consuming search for available vacuum cleaners and the need for operator presence, especially with mobile tools like floor grinders, which obstructs operator visibility and increases dust emission.

Innovation Solution

An automated vacuum cleaner system equipped with a controller, wireless transceiver, location/orientation sensors, and propulsion means that can wirelessly communicate with construction tools to autonomously relocate and connect for servicing, reducing operator intervention and optimizing dust collection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If manual vacuum cleaner allocation is used, then operator control is maintained, but time is lost searching for available vacuum cleaners

Engineering Contradiction:
Improvetime lost searching for vacuum cleanerVSAvoidautomation of vacuum cleaner allocation
Core Design Contradiction:
Loss of timeVSExtent of automation

Solution Approach 1:

The vacuum cleaner system performs self-allocation by automatically detecting construction tools via wireless signals, determining optimal positions, and navigating to service them without operator intervention. The controller autonomously manages vacuum cleaner deployment based on tool locations and availability status.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual mechanical process of operators searching for and connecting vacuum cleaners is replaced by an automated electronic system using wireless transceivers, location sensors, and automated propulsion to detect, locate, and position vacuum cleaners at construction tools.

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

2Ease of operation

If operator presence is required for mobile tools, then vacuum cleaner can be positioned correctly, but operator visibility is obstructed

Engineering Contradiction:
Improvevacuum cleaner positioningVSAvoidoperator line of sight
Core Design Contradiction:
Ease of operationVSIllumination intensity

Solution Approach 1:

The operator's manual positioning task is replaced by an automated system using location sensors to detect tool positions and propulsion means to navigate the vacuum cleaner to the correct position autonomously, eliminating the need for operator presence during positioning.

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

Solution Approach 2:

The automated controller acts as an intermediary between the vacuum cleaner and construction tool, managing the positioning and connection process without requiring direct operator intervention, thereby clearing the operator's line of sight while maintaining operational control.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If one vacuum cleaner is assigned to each construction tool, then dust collection efficiency is maximized, but system cost increases

Engineering Contradiction:
Improvedust collection efficiencyVSAvoidnumber of vacuum cleaners
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The vacuum cleaner allocation system is dynamic rather than static, allowing vacuum cleaners to be reassigned in real-time based on construction tool locations, operational status, and dust collection needs. This enables optimal utilization of fewer vacuum cleaners across multiple tools.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Each vacuum cleaner is designed to service multiple different construction tools rather than being dedicated to a single tool, achieving multi-functionality that reduces the total number of vacuum cleaners needed while maintaining dust collection efficiency across all tools.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Reliability

If vacuum cleaner is stationary, then dust collection is effective, but it obstructs operator movement and visibility

Engineering Contradiction:
Improvedust collection effectivenessVSAvoidoperator mobility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The vacuum cleaner transitions from a stationary to a mobile platform equipped with propulsion means, enabling it to move autonomously to construction tools and follow their positions while maintaining effective dust collection through continuous positional adjustment.

Inventive Principle:
Principle #15Dynamics
