Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing packaging methods for containers with barcodes often require physical elements in the packaging to mask or reveal barcodes, increasing material costs and processing complexities.

Innovation Solution

A system and method that includes a masking apparatus and controller to selectively apply a mask to a container's barcode as it travels along a path, avoiding the need for physical packaging modifications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical elements of packaging are used to mask barcodes, then barcode masking is achieved, but material costs and processing complexities increase

Engineering Contradiction:

Improvebarcode masking reliabilityVSAvoidpackaging structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the barcode masking function from the physical packaging structure and relocates it to a separate masking device that operates independently on the container surface, eliminating the need for complex packaging modifications

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces mechanical packaging modifications with a non-contact or minimal-contact masking apparatus that applies masking material directly to the container surface, substituting complex mechanical packaging structures with a simpler automated masking system

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If physical packaging elements are used for barcode masking, then barcode masking is achieved, but processing time increases

Engineering Contradiction:

Improvebarcode masking reliabilityVSAvoidpackaging processing speed

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent applies barcode masking as a preliminary action during the container handling process, performing masking before final packaging assembly to eliminate sequential processing steps and reduce overall processing time

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements continuous masking operation where the masking apparatus operates continuously as containers move along the processing line, maintaining production flow without interruption or batch processing delays

Inventive Principle:

Principle #20Continuity of useful action

3Reliability

If physical packaging elements are used to mask barcodes, then barcode masking is achieved, but material costs increase

Engineering Contradiction:

Improvebarcode masking reliabilityVSAvoidpackaging material consumption

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The patent uses inexpensive, consumable masking material applied directly to container surfaces instead of expensive reusable packaging components, accepting that the masking material is single-use but significantly reducing overall material costs

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent changes the physical state or form of masking material from permanent packaging components to temporary surface applications, allowing for more economical material selection and reduced material consumption

Inventive Principle:

Principle #35Parameter changes

AI summary

A masking module includes a masking apparatus situated proximate to a path of a container. The masking apparatus is configured to apply a mask to at least a portion of a barcode of the container as the container travels along the path. The masking module also includes a controller in communication with the masking apparatus. The controller is configured to selectively actuate the masking apparatus when the container passes by the masking apparatus along the path.
