Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a light source with wavelength of 405 nm is used for printing, then the printing device can operate with the current light control module, but the light energy is insufficient for producing fine patterns
Solution Approach 1:
The patent changes the wavelength parameter of the light source from 405 nm to shorter wavelengths (375-395 nm range) to increase light energy. This parameter change enables the light to have sufficient energy for curing fine patterns while maintaining compatibility with the light control module through the use of a polarizing element optimized for this wavelength range
2Use of energy by moving object
If a light source with shorter wavelength (higher energy) is used, then the energy for curing fine patterns is sufficient, but the existing light control module cannot effectively control this higher energy light
Solution Approach 1:
The patent introduces a polarizing element as an intermediary component between the light source and the photo-curing material. This polarizing element is specifically designed to work with shorter wavelength light (375-395 nm) and provides effective light control with high polarization degree (98-100%), enabling reliable control of higher energy light for fine pattern printing
3Adaptability or versatility
If the light control module is designed for 405 nm light, then it can control the current light source, but it cannot effectively control higher energy light with shorter wavelength
Solution Approach 1:
The patent modifies the light control module by changing the optical parameters to accommodate shorter wavelengths. The polarizing element is specifically designed with optical properties optimized for 375-395 nm wavelength range, maintaining high polarization degree (98-100%) at these wavelengths, thus enabling the module to effectively control higher energy light while improving adaptability for fine pattern printing
