Solution Overview

Problem

Current thermal printing technologies for retail applications face limitations in versatility and functionality, particularly in creating multisided thermal media combinations that can efficiently integrate and reveal information on multiple surfaces without the need for frequent consumable replacements.

Innovation Solution

The development of multisided thermal media combinations involving substrates with thermally sensitive ink coatings on multiple sides, where at least one substrate is integrated with a pressure-sensitive adhesive and release agent to allow for selective imaging and removal of information, enabling dual-sided printing and label integration within a single print application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If thermal printing is used for retail applications, then consumable costs are reduced and maintenance is minimized, but versatility and functionality are limited when creating multisided thermal media combinations

Engineering Contradiction:
Improveconsumable replacement frequencyVSAvoidmultisided thermal media capability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The label is divided into multiple substrates (first substrate with first label information, second substrate with second label information) that can be selectively removed. This segmentation allows each substrate to serve different functions while maintaining the overall label structure, enabling multisided thermal media capability without requiring separate consumables for each side.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The second substrate is integrated onto the first substrate, creating a nested structure where one label is embedded within another. This nesting allows both labels to coexist on a single thermal media sheet, providing versatility for dual-sided or multi-stage labeling while reducing consumable replacement frequency.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If multiple separate labels are used for different surfaces, then information versatility is improved, but device complexity and consumable management increase

Engineering Contradiction:
Improveinformation presentation capabilityVSAvoidlabel integration structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple substrates containing different label information are merged into a single integrated thermal media structure. The first substrate and second substrate are combined with adhesive layers and release liners, allowing both labels to be applied simultaneously from one media sheet, thereby reducing device complexity compared to managing separate labels.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The thermal media structure is designed to serve multiple functions: it can present first label information on the first substrate, second label information on the second substrate, and allow selective removal of substrates. This multi-functionality is achieved within a single integrated structure, avoiding the need for separate labeling systems.

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

3Strength

If substrates are permanently bonded, then structural integrity is improved, but selective removal and information revelation capability deteriorates

Engineering Contradiction:
Improvesubstrate bonding integrityVSAvoidselective substrate removal
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The adhesive layer is applied selectively to specific regions of the substrates rather than uniformly across all surfaces. This allows certain areas to have strong bonding (where adhesive is present) while other areas remain removable (where release liner is present), enabling both structural integrity and selective removal capability within the same label structure.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

A release liner acts as an intermediary between the adhesive layer and the external environment. The release liner protects the adhesive during storage and application, allowing the substrate to be permanently bonded once the release liner is removed. This intermediary enables both strong bonding when needed and easy removal when the release liner is still in place.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Various multisided thermal media image elements, and methods of manufacture thereof, are presented. In one embodiment, a first media substrate is at least partially coated with thermally sensitive ink on one or more of its sides. A second media substrate is coated with the thermally sensitive ink on at least one of its sides. The second media substrate is at least partially integrated with the first media substrate to form a multisided thermal media image element, wherein at least a portion of the second media substrate is capable of being removed for independent use. The multisided first and second media substrates are adapted to be imaged via a thermal printer individually and together upon integration into the image element.
