Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional manufacturing methods are used without element dispersion agents, then the manufacturing process is simpler, but the uniformity and precision of light-emitting element placement deteriorates
Solution Approach 1:
The element dispersion agent acts as an intermediary substance between the light-emitting elements and the substrate. It contains magnetic metals that respond to external magnetic fields, enabling precise positioning of the light-emitting elements during the manufacturing process without requiring complex mechanical positioning systems
Solution Approach 2:
The patent replaces complex mechanical positioning systems with a magnetic field-based positioning system. The magnetic metals in the element dispersion agent respond to external magnetic fields, allowing for precise and flexible positioning of light-emitting elements without mechanical contact or complex mechanical structures
2Manufacturing precision
If conventional manufacturing methods are used without element dispersion agents, then the manufacturing process is faster, but the uniformity of light-emitting element distribution deteriorates
Solution Approach 1:
The patent replaces mechanical mixing and positioning methods with magnetic field control. The magnetic metals in the element dispersion agent allow for uniform distribution and precise positioning of light-emitting elements through external magnetic fields, improving both uniformity and manufacturing efficiency
Solution Approach 2:
The patent changes the physical and chemical parameters of the manufacturing system by introducing magnetic metals into the element dispersion agent. This allows for dynamic control of element distribution through magnetic field parameters, enabling both uniform dispersion and efficient manufacturing
3Manufacturing precision
If magnetic metals are added to the insulating layer, then the control precision of light-emitting elements improves, but the material complexity increases
Solution Approach 1:
The element dispersion agent serves multiple functions: it provides magnetic responsiveness for precise positioning, maintains insulation properties, and facilitates uniform distribution of light-emitting elements. By combining these functions into a single material system, the patent avoids the need for separate positioning and insulation layers, reducing overall structural complexity
Solution Approach 2:
The patent uses composite materials by incorporating magnetic metals into the insulating layer to create an element dispersion agent with both magnetic and insulating properties. This composite approach allows for precise control while maintaining the necessary electrical insulation, avoiding the need for additional functional layers
