Resin-Molded Ink Cartridge Authentication Imprint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for authenticating ink cartridges, such as hologram stickers or reflectors, are costly and can be easily replicated by counterfeit manufacturers, leading to difficulties in distinguishing genuine from counterfeit products.
Innovation Solution
A method involving the division of a material into portions with unique, irregular patterns of minute depressions and elevations, which are then molded onto the ink cartridge, creating a difficult-to-replicate identifying imprint that can be verified using microscopy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hologram sticker or reflector is used as a mark to indicate genuine ink cartridges, then the authenticity can be detected by reflecting light, but the manufacturing cost becomes relatively high and the mark can be copied by high-skill counterfeit manufacturers
Solution Approach 1:
The patent extracts the authentication function from separate components like hologram stickers or reflectors and integrates it directly into the resin-molded product structure itself. The identifying surface is formed as an integral part of the product during molding, eliminating the need for separate authentication components and reducing manufacturing costs while maintaining reliability.
Solution Approach 2:
The patent merges the authentication mark with the product structure by forming the identifying surface directly in the resin-molded product. This combination eliminates the need for separate hologram stickers or reflectors, reducing manufacturing complexity and cost while maintaining the authentication capability through the integrated identifying surface.
2Reliability
If a hologram sticker or reflector is used as a mark, then light reflection can detect authenticity, but the mark can be replicated by counterfeit manufacturers with high skills
Solution Approach 1:
The patent applies local quality by creating specific identifying surfaces with unique patterns (such as recessed portions, protrusions, or irregular patterns) at particular locations on the resin-molded product. These localized features are integrated into the product structure itself, making them difficult to replicate while maintaining authentication reliability.
Solution Approach 2:
The patent incorporates the identifying surface during the initial molding process rather than adding it later. This preliminary action ensures that the authentication features are built into the product structure from the start, making them inherently difficult to copy and eliminating the need for separate authentication components that could be replicated.
3Reliability
If a mark is added to indicate genuine ink cartridges, then authentication is possible, but the mark can be copied by counterfeit manufacturers
Solution Approach 1:
The patent makes the product itself serve the authentication function by incorporating identifying surfaces directly into the resin-molded structure. The product authenticates itself through its own physical characteristics (patterns, recesses, protrusions) rather than relying on separate marks that could be copied, thereby eliminating the ease of copying while maintaining authentication reliability.

AI summary
A method of forming an identifying imprint on a resin-molded product, includes the step of dividing a material into a first portion and a second portion, to form an identifying surface on at least one of the first portion and the second portion. The method also includes the steps of molding a resin material into the resin-molded product, and transferring an imprint of the identifying surface onto the resin-molded product.
