Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If optical register marks are provided on packaging laminate, then alignment guidance for packaging operations is enabled, but package exterior space is consumed and alignment reliability depends on printing precision

Engineering Contradiction:

Improvealignment precisionVSAvoidpackage exterior space

Core Design Contradiction:

Measurement precisionVSArea of stationary object

Solution Approach 1:

The patent replaces optical register marks with magnetic marks consisting of magnetisable portions that generate magnetic fields. This substitution eliminates the need for visual optical marks on the package exterior while providing alignment guidance through magnetic field detection, thereby resolving the space consumption issue and improving alignment reliability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces magnetic fields as an intermediary between the packaging laminate and the alignment system. Magnetic marks with magnetisable portions create magnetic fields that can be detected by magnetic sensors, providing a reliable alignment reference without occupying package exterior space or depending on printing precision.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If magnetic marks are provided on packaging laminate, then alignment reliability is improved, but manufacturing complexity increases due to additional magnetic field generation equipment

Engineering Contradiction:

Improvealignment reliabilityVSAvoidmanufacturing equipment complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies magnetic marks to the packaging laminate during the printing process, before the packaging operations occur. The magnetisable portions are positioned in advance on the laminate, allowing magnetic field generation to be integrated into existing printing equipment without requiring separate complex magnetic field generation systems.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent combines the magnetic marking function with the existing printing process. The printing equipment that deposits ink or coating also deposits the magnetisable portions, merging two functions into one process and avoiding the need for separate magnetic field generation equipment.

Inventive Principle:

Principle #5Merging (Combining)

3Measurement precision

If magnetisable portions are positioned close to package boundaries, then alignment accuracy is improved, but risk of interference with sealing and forming operations increases

Engineering Contradiction:

Improvealignment accuracyVSAvoidinterference with sealing and forming

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent positions magnetisable portions at specific locations on the packaging laminate, optimizing their placement to provide accurate alignment information while avoiding interference with sealing and forming operations. The local positioning of magnetic marks allows different regions of the laminate to have different functional characteristics.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent uses magnetisable portions that are sufficiently small and strategically positioned to provide the necessary alignment information without excessive magnetic field interference. The partial coverage of magnetisable portions ensures alignment accuracy while minimizing the risk of interfering with nearby sealing and forming operations.

Inventive Principle:

Principle #16Partial or excessive action
