Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional security paper is used, then detection functionality is provided, but dust generation is high and unsuitable for dust-free environments
Solution Approach 1:
The patent uses a composite structure consisting of a plastic layer and a paper layer combined together. The plastic layer provides dust-proof properties while the paper layer maintains detection functionality through embedded magnetic materials or printed codes, resolving the contradiction between low dust generation and reliable detection.
Solution Approach 2:
The invention applies different materials to different layers of the paper product. The plastic layer is designed specifically to reduce dust generation, while the paper layer is optimized for detection purposes. This local differentiation allows each layer to excel at its specific function without compromising the other.
2Strength
If conventional security paper is used, then detection functionality is provided, but water-proof and tear-proof properties are lacking
Solution Approach 1:
By combining plastic material (providing water-proof and tear-proof properties) with paper material (providing detection surface), the composite structure achieves both enhanced mechanical strength and maintained detection functionality. The plastic layer protects the embedded magnetic materials or printed codes from damage.
Solution Approach 2:
The plastic layer acts as a protective shell that encases and protects the detection elements. This flexible protective layer provides water-proof and tear-proof properties while allowing the detection functionality to remain accessible and effective.
3Reliability
If electrical imprint or bar code is used for detection, then detection functionality is provided, but shielding or tearing causes detection failure
Solution Approach 1:
The plastic layer serves as an intermediary protective medium that shields the detection elements (magnetic materials or printed codes) from external damage such as tearing or interference. This protective layer ensures detection functionality remains reliable even under adverse conditions.
Solution Approach 2:
The combination of plastic and paper creates a composite structure where the plastic provides protective shielding while the paper layer maintains the detection elements. This composite approach resolves the vulnerability of conventional detection methods to shielding and tearing.
4Reliability
If two layers of paper are used to embed magnetic material, then detection functionality is provided, but thickness increases
Solution Approach 1:
The invention uses a composite of plastic and paper layers instead of multiple paper layers. This allows embedding of magnetic materials in a thinner, more compact structure while maintaining detection functionality. The plastic layer provides structural support that reduces the need for multiple thick paper layers.
Solution Approach 2:
By changing the material composition from all-paper to plastic-paper composite, the patent achieves the same detection functionality with reduced overall thickness. The plastic material allows for thinner construction while maintaining structural integrity and detection capabilities.
