Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multilayer film is formed on a resin body to reduce optical transmittance in multiple wavelength ranges, then the multifunctional property is achieved, but the process becomes complicated and time-consuming
Solution Approach 1:
The patent combines multiple wavelength-reducing functions into a single resin body by sequentially depositing different functional dyes (first functional dye for first wavelength range, second functional dye for second wavelength range) onto the same base body, thereby achieving multifunctionality without requiring separate multilayer film formation processes
Solution Approach 2:
The resin body is designed to universally reduce optical transmittance across multiple wavelength ranges by incorporating multiple types of functional dyes, allowing a single component to perform multiple wavelength-reducing functions simultaneously
2Reliability
If conventional dyeing and heating methods are used to fix dye onto the resin body, then the functional property is achieved, but cracks may occur in the resin body
Solution Approach 1:
The patent changes the physical state parameters of the functional dye by controlling temperature during the deposition process, using phase transition (sublimation) to transfer the dye onto the resin body and then using controlled heating to fix it, thereby achieving functional integration without causing cracks
Solution Approach 2:
The patent utilizes phase transition of the functional dye from solid to gas (sublimation) during deposition, and then uses controlled heating to facilitate fixation of the dye onto the resin body, avoiding thermal shock and crack formation
3Adaptability or versatility
If multiple separate processes are performed to add different wavelength-reducing functions, then comprehensive optical transmittance reduction is achieved, but the manufacturing time increases
Solution Approach 1:
The patent applies multiple functional dyes to a base body in advance before final fixation, allowing sequential deposition of first functional dye and second functional dye to be prepared and positioned, reducing overall manufacturing time by pre-positioning all necessary functional components
Solution Approach 2:
The patent implements continuous deposition and fixation processes where the first functional dye is deposited and fixed, then the second functional dye is immediately deposited and fixed in sequence, maintaining continuous productive action without interruption to minimize manufacturing time

AI summary
The present invention provides a method for manufacturing a multifunctional resin body that reduces the optical transmittance in a plurality of wavelength bands, the method including: a first step for obtaining a first functionalized substrate by applying, to a substrate, a first functional dye that absorbs light in a first wavelength band and that has sublimability; a second step for placing the first functionalized substrate and a functional resin body in opposition to each other, the functional resin body having a function for reducing the optical transmittance in a second wavelength band, which is a wavelength band different from the first wavelength band, and for heating the first functionalized substrate so as to cause sublimation of the first functional dye, thereby causing the first functional dye to adhere to the functional resin body; and a third step for heating the functional resin body having the first functional dye adhering thereto, thereby fixing the first functional dye on the functional resin body, wherein a multifunctional resin body is obtained by adding a function for reducing the optical transmittance in the first wavelength band to the functional resin body by using the first functional dye.
