Hot-Melt Adhesive Tagging for Icy Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing product tagging technologies face challenges in efficiently attaching tags to diverse products and packages, particularly those with moist, icy, rough, or fragile surfaces, which often result in poor adhesion and tag detachment.
Innovation Solution
The use of a hot-melt adhesive to attach wireless readable tags to products or packages, which can be applied as a shot or droplet onto the surface, effectively removing moisture or ice and improving adhesion without requiring high pressure, thus accommodating uneven or fragile surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive labels are used to tag products, then tagging can be performed manually or automatically, but adhesion is poor on moist, icy, or rough surfaces causing tag detachment
Solution Approach 1:
The patent changes the physical state of the adhesive from liquid to solid through phase transition upon cooling. The adhesive is applied in liquid form to ensure good wetting and adhesion to the surface, then it solidifies through phase change to provide strong bonding that resists moisture and ice, resolving the contradiction between adhesion reliability and surface moisture conditions
Solution Approach 2:
The adhesive acts as an intermediary substance between the tag and the product surface. It mediates the bonding interface, allowing the tag to adhere reliably even on challenging surfaces by providing a bonding layer that is applied in liquid form for coverage and then solidifies for strength, overcoming the harmful effects of surface moisture and ice
2Reliability
If high pressure is applied during tagging, then adhesion may be improved, but fragile products or packages may be damaged
Solution Approach 1:
The adhesive undergoes parameter change from liquid to solid state through phase transition. When applied in liquid form, it provides good wetting without requiring high pressure. Upon solidification through cooling, it develops strong bonding properties, thus achieving reliable adhesion without subjecting fragile products to damaging high pressure forces
3Adaptability or versatility
If manual tagging is performed, then flexibility in handling diverse products is maintained, but tagging becomes resource intensive and time consuming
Solution Approach 1:
The adhesive system provides self-service functionality by automatically adapting to different surface conditions through its phase change mechanism. The liquid-to-solid transition occurs automatically upon application and cooling, eliminating the need for manual pressure application or adjustment, thereby enabling automated tagging systems to handle diverse products efficiently without sacrificing adaptability
Solution Approach 2:
The patent replaces the mechanical pressure application process with a thermal phase change process. Instead of relying on mechanical force to ensure adhesion, the system uses thermal energy to drive the adhesive from liquid to solid state, enabling automated tagging without complex pressure control mechanisms while maintaining versatility across different product types

AI summary
The invention relates to a method for tagging (101) products or product packages by applying hot-melt adhesive (103) to removably or permanently attach (104) a remote-readable tag (202) with an identification element (102) onto the product or product package. Hot-melt adhesive is targeted as a shot onto a surface of the product or product package. Hot-melt adhesive removes moisture and/or layer of ice from the surface of the product or product package thereby facilitating removable or permanent attachment (104) of the remote-readable tag (102) onto the product or the product package. A corresponding product or product package tagged according to the method is presented.
