Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If phthalocyanine-based compounds are used as absorbents, then near-infrared light absorption is achieved, but visible light absorption becomes too high
Solution Approach 1:
The patent modifies the molecular structure of phthalocyanine-based compounds by introducing specific substituents and adjusting the conjugation system, thereby changing the absorption spectrum parameters to reduce visible light absorption while maintaining near-infrared absorption capabilities
Solution Approach 2:
The patent creates composite absorbent materials by combining phthalocyanine-based compounds with other functional groups or materials that have complementary absorption characteristics, achieving a balance between visible and near-infrared absorption properties
2Use of energy by moving object
If cyanine-based compounds are used for near-infrared absorption, then absorption in the near-infrared range is achieved, but the absorption range becomes narrow requiring mixing with other compounds
Solution Approach 1:
The patent develops a universal absorbent compound structure that inherently provides broad near-infrared absorption coverage, eliminating the need to mix multiple compounds by designing a single molecule with extended conjugation and appropriate substituents that create a wide absorption spectrum
3Use of energy by moving object
If metal dithiol complex compounds are used as absorbents, then light absorption properties are achieved, but solubility becomes low requiring additional dispersion equipment
Solution Approach 1:
The patent introduces hydrophilic substituents or functional groups at specific locations in the metal dithiol complex structure to improve solubility in particular solvents, while maintaining the core light-absorbing functionality through careful selection of substituents that do not compromise the chromophore
Solution Approach 2:
The patent uses solvent dispersants or surfactants as intermediary substances to facilitate the dispersion of metal dithiol complex compounds in the desired medium, overcoming the low solubility issue without requiring complex dispersion equipment
4Use of energy by moving object
If iminium or diimonium compounds are used for absorbing light at 900 nm or more, then high wavelength absorption is achieved, but thermal stability becomes low causing loss of absorption properties in high temperature and humidity environments
Solution Approach 1:
The patent modifies the molecular structure of iminium or diimonium compounds by changing substituents, adjusting the conjugation length, or introducing rigid frameworks to improve thermal stability while maintaining the ability to absorb light at wavelengths of 900 nm or more
Solution Approach 2:
The patent creates composite structures by combining iminium or diimonium chromophores with thermally stable scaffolds or protective groups that enhance overall thermal and oxidation resistance while preserving the high-wavelength absorption properties
5Use of energy by moving object
If existing absorbent compounds are used, then light absorption characteristics are achieved, but oxidation resistance becomes low leading to loss of spectral properties in high temperature and high humidity conditions
Solution Approach 1:
The patent introduces oxidation-resistant functional groups or electron-withdrawing substituents at specific positions in the absorbent molecule to enhance overall oxidation resistance while preserving the light absorption characteristics through careful selection of groups that do not compromise the chromophore
Solution Approach 2:
The patent incorporates protective groups or molecular designs that create an inert-like protective environment around the sensitive chromophore, shielding it from oxidation by moisture and oxygen in high-temperature, high-humidity environments
