Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If optical guiding marks are used on packaging material, then position information can be provided for forming and sealing processes, but valuable exterior surface area is consumed and the marks cannot be miniaturized further without losing detectability
Solution Approach 1:
The patent replaces optical guiding marks with magnetic marks. Instead of using optical detection systems that require visible marks on the packaging material surface, the invention uses magnetic fields and magnetic sensors to detect position information. This substitution eliminates the need for optical marks on the exterior surface, freeing up valuable packaging area while maintaining or improving detection precision through magnetic field sensing capabilities.
2Area of stationary object
If the physical size of optical marks is reduced to save surface area, then exterior surface consumption is reduced, but the marks become too small to be detectable with required accuracy
Solution Approach 1:
The invention substitutes optical detection with magnetic detection. Magnetic marks can be detected with high precision regardless of their physical size on the packaging surface, as magnetic sensors can detect the magnetic field signature from very small magnetic particles or patterns. This allows the use of extremely compact magnetic marks that consume minimal exterior surface area while maintaining detectability and position accuracy.
Solution Approach 2:
The invention changes the detection parameter from optical properties (visible light reflection/absorption) to magnetic properties (magnetic field strength and direction). This parameter change enables the use of much smaller marks because magnetic detection is not limited by the diffraction limits of light or the resolution of optical sensors in the same way optical detection is. The magnetic marks can be miniaturized to dimensions that would be undetectable by optical means.
3Loss of information
If magnetic marks are used to convey complex data, then information transfer capability is enhanced, but the system complexity increases
Solution Approach 1:
The patent replaces complex optical mark systems with a magnetic field-based information system. Magnetic marks can encode complex data through variations in magnetic field strength, direction, and patterns, allowing multiple bits of information to be conveyed by each mark. The magnetic sensor system reads these variations and translates them into actionable information for the packaging process, providing high information density without requiring physically large or visually complex marks on the packaging material.
