Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If piecewise magnetic elements are used for magnetizing surfaces, then magnetic functionality can be achieved, but the process becomes time-consuming and requires manual effort
Solution Approach 1:
The patent combines multiple magnetic elements into a single continuous magnetic layer applied via inkjet printing. Instead of placing individual magnets piece by piece, the magnetic material is deposited as a continuous layer that can be quickly printed onto the surface, dramatically reducing integration time while maintaining magnetic functionality.
Solution Approach 2:
The patent replaces manual mechanical placement of magnetic elements with an automated inkjet printing process. The printing system deposits magnetic material precisely controlled by digital data, eliminating manual handling and assembly operations, thereby reducing both time and labor requirements.
2Reliability
If piecewise magnetic elements are used, then magnetic signal functionality can be achieved, but additional costs and time are required for selection and manufacturing
Solution Approach 1:
The patent creates a universal magnetic layer that can be applied to various surfaces and configurations through inkjet printing. The same printing system and magnetic material formulation can produce different magnetic patterns and functionalities by changing digital data, eliminating the need to select from pre-manufactured magnetic components for different applications.
Solution Approach 2:
The patent uses digital data to control the precise placement and pattern of magnetic material during printing. The magnetic layer is created as a direct copy of the desired magnetic pattern from digital files, eliminating the need for physical templates, molds, or pre-manufactured magnetic components, thereby reducing manufacturing costs and time.
3Area of stationary object
If bulky magnetic elements are used for larger surfaces, then magnetic coverage can be achieved, but space must be planned and taken into account during installation
Solution Approach 1:
The patent applies magnetic material as a thin, flexible layer through inkjet printing rather than using bulky three-dimensional magnetic elements. The magnetic layer can be deposited as a thin film that conforms to the surface geometry, providing comprehensive coverage without occupying significant space or requiring complex space planning during installation.
4Reliability
If thermal treatment above 120°C is used for curing the magnetizable layer, then good adhesion and flexibility can be achieved, but compatibility with elastomeric substrates is compromised
Solution Approach 1:
The patent modifies the chemical composition and molecular structure of the binder system to enable curing at low temperatures below 120°C. By changing the chemical parameters of the binder, the system achieves adequate crosslinking and adhesion without requiring high-temperature processing that would damage elastomeric substrates, thus maintaining both adhesion and flexibility.
