Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rare earth elements are added to glass substrate to absorb ultraviolet rays, then ultraviolet absorption capability is improved, but manufacturing cost increases
Solution Approach 1:
The patent replaces expensive rare earth elements with organic ultraviolet absorbers that are cheaper and can be applied as coatings. The coating layer acts as a disposable protective layer that can be applied economically through coating processes rather than requiring expensive bulk glass modification with rare earth elements.
Solution Approach 2:
The patent creates a composite structure by adding an ultraviolet absorption coating layer on top of the glass substrate. This composite approach combines the UV absorption properties of organic compounds with the structural integrity of glass, achieving UV protection without the high cost of rare earth element-doped glass.
2Reliability
If ultraviolet absorber is added to intermediate membrane of laminated glass, then ultraviolet absorption capability is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent extracts the ultraviolet absorption function from the intermediate membrane of laminated glass and applies it directly to the glass surface through coating. This eliminates the need for complex laminated structures with UV-absorbing membranes, simplifying the overall glass construction while maintaining UV protection.
Solution Approach 2:
The ultraviolet absorption coating can be applied to various types of glass (laminated, tempered, monolithic) without requiring structural changes. This universal application approach eliminates the need for specialized UV-absorbing intermediate membranes in laminated glass, reducing manufacturing complexity across different glass product lines.
3Reliability
If ultraviolet absorption coating is applied on glass surface, then ultraviolet absorption capability is improved, but discoloration and devitrification occur reducing weather resistance
Solution Approach 1:
The patent modifies the chemical composition parameters of the coating by incorporating specific metal oxides (vanadium, manganese, cobalt, nickel) along with silicon oxide and ultraviolet absorbers. These compositional changes enhance the coating's stability and resistance to discoloration and devitrification while maintaining UV absorption capability.
Solution Approach 2:
The patent creates a composite coating material combining silicon oxide matrix, ultraviolet absorbers, and transition metal oxides. This composite formulation provides both UV absorption functionality and enhanced weather resistance, preventing the discoloration and devitrification issues that plague simpler UV coating formulations.

AI summary
Coating liquid used for forming an ultraviolet absorption coating on a surface of an object such as glass and the like, ultraviolet absorption glass arranged with the ultraviolet absorption coating formed by the coating liquid, and a method for preparing the ultraviolet absorption glass. The coating liquid used for forming the ultraviolet absorption coating, the ultraviolet absorption glass and the method for forming the ultraviolet absorption glass, by storing and releasing electrons excited by ultraviolet lights in an ultraviolet absorber, reduce the excited electrons that are gradually accumulated during a process in which the ultraviolet absorber absorbs the ultraviolet lights, thus protecting the ultraviolet absorber and a silicon dioxide matrix, preventing the ultraviolet absorption glass from discoloring or devitrifying, ensuring weather resistance of the ultraviolet absorption coating and ensuring color consistency of the ultraviolet absorption glass.
