Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If invisible photoluminescent or fluorescent ink codes are used on labels, then automatic recognition and adaptation to different label types is enabled, but the cost of additional imaging equipment and ink increases
Solution Approach 1:
The patent replaces manual visual inspection and manual parameter adjustment with an automated optical imaging system. The sensor detects invisible photoluminescent or fluorescent ink codes on labels, automatically identifying label types and triggering corresponding processing parameters without human intervention.
Solution Approach 2:
The patent employs invisible photoluminescent or fluorescent inks that emit light at specific wavelengths when excited. These inks are invisible to the human eye under normal conditions but can be detected by the sensor, providing a cost-effective coding mechanism that doesn't interfere with visible label designs.
2Loss of information
If visible codes are printed on labels, then label type identification is possible, but the codes interfere with existing prints and decorative elements
Solution Approach 1:
The patent uses invisible photoluminescent or fluorescent inks that are not visible under normal lighting conditions. These inks only become detectable when excited by specific wavelengths of light in the imaging system, allowing code information to be embedded without affecting the visual appearance or interfering with existing label designs.
Solution Approach 2:
The patent substitutes visible optical codes with invisible photoluminescent or fluorescent codes. This replacement eliminates the visual interference problem while maintaining the information-carrying capability, as the invisible codes can be detected and decoded by the specialized sensor without competing with visible print elements.
3Manufacturing precision
If manual adjustment of operating parameters is required for each label type, then processing accuracy can be maintained, but productivity and efficiency decrease
Solution Approach 1:
The patent implements a self-identifying label system where each label type carries invisible photoluminescent or fluorescent code information that automatically communicates its processing requirements to the imaging system. The system self-adjusts operating parameters based on the detected code, eliminating the need for manual intervention while maintaining precision.
Solution Approach 2:
The patent establishes a feedback loop where the sensor detects the invisible code on each label, the system processor interprets the label type information, and the appropriate operating parameters are automatically applied. This closed-loop control ensures processing accuracy matches that of manual adjustment while achieving high-speed automated operation.
4Extent of automation
If RFID chips are used for label identification, then automatic recognition is achieved, but additional costs are significantly higher compared to invisible ink
Solution Approach 1:
The patent employs inexpensive photoluminescent or fluorescent inks as disposable coding media on labels. Unlike expensive reusable RFID chips, these inks can be applied directly to each label during manufacturing at very low cost, making the system economically viable for high-volume label processing applications.
Solution Approach 2:
The patent changes the identification medium from electronic RFID chips to optical photoluminescent or fluorescent inks. This parameter change in the identification technology reduces costs dramatically while maintaining automated recognition capability, as the optical inks can be detected by relatively simple and inexpensive sensors compared to RFID reading systems.
