Solution Overview

Problem

Existing packaging technologies face challenges with register marks that consume package space and require precise alignment, which can be inefficient and prone to errors during the formation and finishing of packaging containers.

Innovation Solution

Incorporating magnetisable portions with magnetic marks on packaging laminates, allowing for magnetic marking that provides positioning information and complex data, enabling accurate alignment and efficient finishing operations without consuming valuable package space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If optical register marks are provided on packaging laminate, then positioning information can be read during packaging operations, but the marks consume non-negligible area of the package exterior and require precise alignment between printing and finishing operations

Engineering Contradiction:
Improvepositioning information accuracyVSAvoidpackage exterior area
Core Design Contradiction:
Measurement precisionVSArea of stationary object

Solution Approach 1:

The patent replaces optical register marks with magnetic marks that utilize magnetic field interactions. Magnetic marks consist of magnetisable portions that can be read by magnetic sensors during packaging operations, eliminating the need for optical reading systems and the associated alignment requirements between printing and finishing operations.

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

Solution Approach 2:

The patent changes the physical parameter used for information encoding from optical (visual patterns) to magnetic (magnetic field patterns). This allows positioning information to be stored in the magnetic properties of the packaging material rather than consuming exterior surface area, enabling reliable reading without visual alignment.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If optical register marks are used for guiding packaging operations, then positioning can be detected, but the marks are prone to alignment errors between printing and finishing operations

Engineering Contradiction:
Improvealignment reliabilityVSAvoidalignment precision
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent replaces optical detection systems with magnetic detection systems. Magnetic marks and magnetic sensors provide more reliable detection that is less sensitive to alignment errors, as magnetic fields can penetrate through packaging materials and maintain consistent readings even when optical alignment is imperfect.

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

Solution Approach 2:

The patent introduces magnetic fields as an intermediary between the packaging material and the detection system. Magnetic marks embedded in the packaging laminate create magnetic field patterns that serve as reliable intermediaries for positioning information, decoupling the reading process from direct optical alignment requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Quantity of substance

If magnetic marks are provided on packaging laminate, then positioning information and complex data can be stored without consuming package space, but magnetic marking systems require integration with existing packaging machinery

Engineering Contradiction:
Improvedata storage capacityVSAvoidmagnetic marking system complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent makes the packaging laminate itself multi-functional by embedding magnetic marks within the material structure. The same packaging material that provides containment also stores positioning information and complex data through its magnetic properties, eliminating the need for separate data storage components and reducing overall system complexity.

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

Solution Approach 2:

The patent merges the packaging function with the data storage function into a single integrated system. Magnetic marks are incorporated directly into the packaging laminate during manufacturing, combining the structural packaging material with the information carrier, thereby reducing the number of separate components and simplifying the overall system.

Inventive Principle:
Principle #5Merging (Combining)
