Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If small line widths are used to increase transparency, then transparency is improved, but wiring reliability deteriorates due to easy disconnection
Solution Approach 1:
The patent applies curvature to the wiring pattern by using wave-shaped traces instead of straight lines. This curved configuration allows the wiring to accommodate thermal expansion and mechanical stress without disconnection, thereby maintaining reliability while using thin line widths for transparency.
Solution Approach 2:
The patent changes the geometric parameters of the wiring by introducing wave patterns with specific wavelengths and amplitudes. This transformation from straight to curved geometry fundamentally alters how the wiring responds to stress and heat, improving reliability without compromising the thin line width needed for transparency.
2Reliability
If polygonal wiring patterns are used to compensate for disconnections, then wiring reliability is improved, but noise generation worsens due to sharp bends
Solution Approach 1:
The patent replaces sharp angular bends with smooth curved transitions in the wave pattern. This eliminates the abrupt direction changes that cause electromagnetic radiation and noise, while the continuous curved path maintains wiring reliability by accommodating stress without disconnection.
Solution Approach 2:
The patent converts the potentially harmful sharp bends into beneficial smooth curves. The curved wave pattern that would normally be considered a deviation from straight-line efficiency actually serves to reduce noise generation while maintaining or improving reliability through stress accommodation.
3Ease of manufacture
If rectangular or hexagonal patterns are used, then manufacturing ease is improved, but pattern breakage worsens in the direction of travel
Solution Approach 1:
The patent uses curved wave patterns that can be easily defined by simple sinusoidal or similar mathematical functions, making them straightforward to manufacture using standard PCB routing or photolithography processes. The continuous curved geometry eliminates the sharp corners of polygonal patterns that are prone to breakage during manufacturing and operation.
