Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In the aircraft manufacturing sector, operators face ergonomic discomfort and inefficiency when drilling large-size structural parts, as they must manually hold both the drilling tool and a suction pipe for dust and chip removal, often requiring a second operator to assist with the suction.

Innovation Solution

A suction spout or nozzle system is integrated with a magnetic attachment mechanism that connects to existing drilling templates, allowing for stable and precise positioning, enabling efficient removal of dust and chips without the need for additional personnel, utilizing a tubular cylindrical design with a permanent magnet for secure attachment and adjustable orientation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If an operator manually holds both the drilling tool and suction pipe, then dust and chips can be removed during drilling, but the operator experiences ergonomic discomfort and operational inefficiency

Engineering Contradiction:

Improvedust and chip removal effectivenessVSAvoidoperator ergonomic comfort

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The invention combines the drilling tool and suction pipe into a single integrated device. The suction pipe is mounted on the drilling tool handle, allowing both drilling and dust extraction functions to be performed simultaneously through one unified tool rather than requiring separate manual handling of multiple components.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated device serves multiple functions: it performs both drilling operations and dust/chip removal through the incorporated suction system. This multi-functional design eliminates the need for separate tools and reduces operational complexity while maintaining effective dust extraction capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Object-affected harmful factors

If a second operator is used to hold the suction pipe, then dust and chips are effectively removed, but device complexity and operational cost increase

Engineering Contradiction:

Improvedust and chip removal effectivenessVSAvoidoperational personnel requirements

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The suction capability is merged directly into the drilling tool structure, creating a self-contained system that performs both drilling and dust extraction independently. This integration eliminates the need for additional personnel to operate separate suction equipment.

Inventive Principle:

Principle #5Merging (Combining)

3Object-affected harmful factors

If the suction pipe is manually held during drilling, then dust removal is possible, but productivity decreases due to additional operational steps

Engineering Contradiction:

Improvedust and chip removalVSAvoiddrilling operation efficiency

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

The drilling and dust removal functions are merged into a single integrated tool, allowing both operations to occur simultaneously without requiring separate manual handling steps. This increases productivity by streamlining the workflow into one unified operation.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated drilling tool with built-in suction capability performs multiple functions (drilling and dust extraction) through a single device, eliminating the need for sequential operations or additional personnel and thereby improving overall operational efficiency.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A nozzle removes by suction dust and chips from a drilling machine in an industrial plant. The nozzle has a first tubular portion for connection to a suction tube communicating with an opposite second tubular portion with an intake opening. An outer flange extends transversely from an intermediate position between the first and second tubular portions. The intake opening is directed in a lateral direction, parallel to the transverse direction of the flange. A magnetic element is incorporated in the flange. The nozzle can be applied to a drilling template having cylindrical through-openings in which respective bushings made of ferromagnetic material are fixed. When the second tubular portion is inserted through a cylindrical bushing, the magnetic element acts on the bushing, opposing axial and rotational movements of the nozzle.
