Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing forgery-proof labels are difficult for consumers to recognize and can be easily reused or forged, leading to the proliferation of counterfeit products and losses for both consumers and legitimate manufacturers.
Innovation Solution
A forgery-proof label comprising a thin film battery and an OLED display unit that displays a preset pattern when powered, with an encapsulation layer and thin film to control corrosion and prevent reuse, along with a removable insulation sheet for power access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional identification methods are used, then the label is simple to manufacture, but it is difficult for consumers to recognize and easy to forge
Solution Approach 1:
The patent employs an OLED display unit that can dynamically change colors and display patterns to create visually distinctive and recognizable labels. The OLED element emits light in different colors (red, green, blue, yellow, cyan, magenta) to display preset patterns or random patterns, making the label easily recognizable by consumers and difficult to forge due to the complexity of replicating the dynamic display functionality
Solution Approach 2:
The patent replaces traditional static mechanical identification methods with an electronic display system. The OLED display unit powered by a thin film battery provides dynamic visual identification, substituting simple physical labels with an electronically controlled display that can show various patterns and colors, thereby enhancing anti-forgery capability while maintaining manufacturing feasibility
2Ease of manufacture
If the label uses simple identification features, then it is easy to manufacture, but it can be easily reused or forged
Solution Approach 1:
The OLED display unit serves multiple functions: it displays preset patterns for identification, generates random patterns for anti-forgery verification, and can show different colors for various states. This multi-functionality allows a single device to provide both simple manufacturing compatibility and complex identification capabilities, preventing reuse and forgery while maintaining ease of manufacture
3Ease of operation
If the label provides clear visual identification, then it is easily recognizable, but it may be more difficult to manufacture
Solution Approach 1:
The patent uses a thin film battery and flexible OLED display unit that can be adhered to, printed on, or transferred to various surfaces. This flexible form factor allows the complex visual identification system to be manufactured as a thin, adaptable label that can be applied to different products, balancing consumer recognition ease with manufacturing feasibility through flexible substrate technology
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The label is easily recognizable, difficult to forge, and prevents reuse through controlled corrosion, enhancing its identifying characteristics and discouraging counterfeiting.
Implementation Method 1
the organic functional layer is operable to provide light emission upon application of power supplied by the thin film battery to the anode layer and the cathode layer
Implementation Method 2
the encapsulation layer is arranged to define a path along which water and oxygen corrode the OLED element
