Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If display analysis techniques are improved, then display analysis capability is enhanced, but counterfeiting becomes easier
Solution Approach 1:
The patent changes the physical parameters of the display surface by introducing microparticles with specific sizes (0.1-10 μm), refractive indices (1.3-1.7), and spacing (0.5-5 μm). These parameter changes create optical effects that are difficult to replicate, enhancing anti-counterfeiting while maintaining analysis capability through controlled optical properties
Solution Approach 2:
The patent uses composite structures combining transparent resin materials with dispersed microparticles. This composite approach creates complex optical properties including diffraction, interference, and scattering effects that are difficult to counterfeit while allowing for controlled analysis of the display characteristics
2Adaptability or versatility
If display manufacturing techniques are diversified, then manufacturing flexibility is improved, but counterfeiting facilitation increases
Solution Approach 1:
The patent applies local quality by varying microparticle properties (size, shape, refractive index, material composition) in different regions or layers of the display. This allows customized optical effects for different display areas while maintaining complex anti-counterfeiting characteristics that are difficult to replicate
Solution Approach 2:
The patent enables manufacturing flexibility through controlled variation of microparticle parameters including size distribution, concentration, spatial arrangement, and material composition. These parameter changes allow adaptation to different display applications while creating unique optical signatures for anti-counterfeiting
3Ease of manufacture
If unit reflecting surfaces are provided for respective pixels, then designability is improved, but device complexity increases
Solution Approach 1:
The patent segments the display surface into discrete pixel units, each containing microparticles with specific optical properties. This segmentation allows independent design and control of each pixel's optical characteristics while simplifying the overall design process through modular approaches
Solution Approach 2:
The patent replaces complex mechanical or geometric surface structures with optically active microparticles suspended in resin. This substitution achieves complex optical effects through material properties rather than intricate surface geometries, reducing manufacturing complexity while maintaining design flexibility
4Reliability
If microparticles are arranged in particle array planes, then optical function is enhanced, but manufacturing precision requirements increase
Solution Approach 1:
The patent achieves sufficient optical functionality without requiring perfect long-range order in microparticle arrangement. By using partial ordering or localized array structures rather than complete periodic lattices, the patent maintains effective optical functions (diffraction, interference) while reducing manufacturing precision requirements
Solution Approach 2:
The patent optimizes microparticle parameters including size (0.1-10 μm), spacing (0.5-5 μm), and concentration to achieve desired optical effects with relaxed positioning tolerances. These parameter changes allow effective optical functionality without requiring ultra-precise particle placement

AI summary
A display includes a plurality of pixels arranged in matrix. Each of the pixels includes a single reflecting surface, and all the reflecting surfaces include a set of the reflecting surfaces that allow light incident in a predetermined direction to be reflected in a direction predefined for the respective reflecting surfaces, so that light reflected by all the reflecting surfaces forms an image which appears in a specific direction, which is a direction common to all the reflecting surfaces.
