Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing labels are used for container protection, then basic identification function is provided, but reliable and long-lasting protection against electromagnetic radiation and gas transmission is not achieved
Solution Approach 1:
The patent combines multiple protective functions (radiation protection, gas barrier, electronic identification, visual inspection) into a single integrated label structure. The radiation protection layer and gas barrier layer are directly or indirectly coupled to form one multifunctional label, eliminating the need for separate protective components and achieving reliable protection without proportionally increasing complexity.
Solution Approach 2:
The label is designed to perform multiple functions simultaneously: protecting against electromagnetic radiation, blocking gas transmission, enabling electronic identification through RFID/NFC components, and allowing visual inspection through transparent sections. This multi-functionality approach addresses the reliability requirement while maintaining cost-effectiveness by consolidating multiple protection needs into one product.
2Reliability
If multiple protective layers are added to achieve reliable protection, then protection effectiveness is improved, but manufacturing cost and complexity increase
Solution Approach 1:
The radiation protection layer and gas barrier layer are designed to be directly or indirectly coupled, forming an integrated structure that can be manufactured as a single unit. This merging approach maintains protection effectiveness while simplifying the manufacturing process compared to assembling multiple separate protective components.
Solution Approach 2:
The patent uses thin film structures for both the radiation protection layer and gas barrier layer. These flexible, thin-film solutions provide effective protection while being cost-effective and simple to manufacture, avoiding the need for thick, rigid, or complex protective structures.
3Reliability
If the label provides complete coverage for protection, then protection effectiveness is maximized, but inspection capability is reduced
Solution Approach 1:
The label incorporates transparent sections or inspection windows that provide localized areas for visual inspection while the rest of the label maintains full protective coverage. This local differentiation allows the label to simultaneously achieve comprehensive protection and easy inspection capability without compromising either function.
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 provides reliable and durable protection against light and gas, allowing for inspection windows and electronic identification, suitable for pharmaceutical containers, in a simple and cost-effective way.
Implementation Method 1
The radiation protection layer is adapted to predeterminedly reduce a transmission of electromagnetic radiation in a given wavelength range... The electromagnetic radiation that is to be prevented from passing through the multifunctional label by means of the radiation protection layer is to be arranged in the ultraviolet and/or visible spectral range
Implementation Method 2
The pigments are designed to absorb and/or reflect a predetermined amount of ultraviolet radiation. The color print is designed to absorb and/or reflect a predetermined wavelength range of visible light
Implementation Method 3
The gas barrier layer is adapted to reduce a transmission of a gaseous substance in a predetermined manner... The gaseous substance that is to be prevented from passing through the multifunctional label by means of the gas barrier layer can relate to a pure gas, such as oxygen, and/or to a gas mixture, such as air or water vapor
Implementation Method 4
The radiation protection layer and the gas barrier layer are directly or indirectly coupled to each other... an adhesive layer, by means of which the multifunctional label can be easily and reliably adhered to the object
