Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If thick ITO conductive film is used for wiring, then the conductive wire has sufficient current carrying capacity, but the electric response speed is low
Solution Approach 1:
The conductive wire is segmented into multiple secondary conductive wires (5-20 wires) arranged in parallel, forming a mesh structure. Each secondary wire has a line width of 1-10 μm, and the distance between adjacent wires is 20-50 μm. This segmentation reduces the resistance of each individual wire while maintaining sufficient current carrying capacity through the combined effect of multiple parallel conductors, thereby achieving fast electric response speed.
2Speed
If the conductive wire line width is reduced to increase response speed, then the electric response speed improves, but the wire becomes more fragile and harder to manufacture
Solution Approach 1:
Instead of manufacturing a single thin conductive wire, the invention segments the conductor into multiple secondary wires (5-20 wires) with manageable line widths of 1-10 μm. This segmentation makes each individual wire easier to manufacture with existing technology while achieving the desired low resistance through the parallel arrangement. The mesh structure with 20-50 μm spacing between wires facilitates precise manufacturing.
Solution Approach 2:
The invention optimizes specific parameters: secondary wire line width (1-10 μm), distance between adjacent wires (20-50 μm), and number of parallel wires (5-20). These parameter changes enable the conductive wire to achieve both fast response speed and ease of manufacture by balancing the trade-off between wire thickness and resistance.
3Length of moving object
If the LED panel light is made thinner for flexibility, then the flexibility and light transmission improve, but the protective capability decreases
Solution Approach 1:
The invention embeds the mesh-type conductive wires within grooves on the flexible base film, transitioning the conductive structure from a surface-level thick layer to an integrated three-dimensional structure. This allows the panel to be made thinner overall while maintaining protective capabilities through the groove structure that houses and protects the conductive wires.
Solution Approach 2:
The invention uses a flexible base film with integrated grooves to house the conductive wires, replacing traditional thick rigid conductive layers. This flexible film structure provides both the desired thinness for flexibility and light transmission, while the groove structure embedded within the film provides protective capability against scratches and damage.
