Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If regular uniform patterns of transparent apertures are used in defining layers, then manufacturing is simplified and aperture alignment is easier, but diffraction interference occurs that distorts signal content and reduces signal exchange effectiveness
Solution Approach 1:
The patent applies asymmetry by transitioning from regular uniform aperture patterns to non-uniform irregular patterns in the defining layers. The non-uniform spacing and positioning of apertures eliminate the periodic structure that causes diffraction interference, thereby preserving signal integrity while maintaining manufacturability through updated deposition processes
2Adaptability or versatility
If transparent apertures are introduced for signal exchange, then communication capability is enabled, but diffraction effects interfere with the transmitted EM radiation and reduce signal quality
Solution Approach 1:
The patent uses non-uniform aperture patterns to eliminate diffraction interference while maintaining signal exchange functionality. The irregular spacing breaks the diffraction pattern formation, allowing reliable signal transmission through the transparent apertures without the periodic interference that would occur with regular patterns
Solution Approach 2:
The patent changes the spatial parameters of the aperture patterns from uniform to non-uniform distributions. By varying the spacing, size, and positioning parameters of the apertures in the defining layers, the system maintains signal exchange capability while eliminating diffraction effects that degrade signal quality
3Productivity
If multiple defining layers with apertures are deposited, then transmissive regions are formed for signal exchange, but the regular patterns create diffraction that distorts transmitted signals
Solution Approach 1:
The patent applies asymmetry to the multi-layer aperture structures by using non-uniform patterns in each defining layer. This eliminates the coherent diffraction that would occur with aligned regular patterns across multiple layers, preserving signal integrity while maintaining the productivity benefits of having multiple transmissive regions for efficient signal exchange
