Innovation Solution
Utilize 3-D printing techniques, such as laser sintering, to generate and apply textures with controlled root mean square roughness between 40 to 1000 microns and autocorrelation function greater than 0.5 for distances less than 50 microns, enabling precise control over texture on glass surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional texturing methods (sandblasting, EDM, machining, laser/chemical etching) are used to texture glass tools, then the glass can be textured, but the texture cannot be precisely controlled at scales below 500 microns, resulting in high gloss and limited control over optical properties
Solution Approach 1:
The patent applies parameter changes by utilizing 3-D printing technology to precisely control texture parameters (autocorrelation function and root mean square roughness) at scales below 500 microns, transforming the manufacturing process from traditional methods that cannot control these parameters to a method that enables precise dimensional and surface finish control
Solution Approach 2:
The patent replaces traditional mechanical texturing methods (sandblasting, EDM, machining, laser/chemical etching) with 3-D printing technology, substituting mechanical and chemical processes with an additive manufacturing process that provides superior precision and control over texture characteristics
2Manufacturing precision
If traditional texturing methods are used, then glass can be textured, but the gloss remains high and optical properties cannot be precisely controlled
Solution Approach 1:
The patent changes the surface finish parameters by controlling the autocorrelation function and root mean square roughness through 3-D printing, thereby modifying the optical properties including reducing gloss while maintaining desired transmissivity and aesthetic appearance
Solution Approach 2:
The patent applies local quality by creating specific texture patterns with controlled autocorrelation functions at different locations and scales on the glass surface, enabling different regions to have optimized optical properties for specific functions such as reduced gloss in certain areas while maintaining transmissivity
3Manufacturing precision
If 3-D printing is used to create texture patterns, then precise texture control below 500 microns is achieved, but the manufacturing process becomes more complex
Solution Approach 1:
The patent utilizes parameter changes inherent to 3-D printing technology to achieve precise control over texture dimensions and surface characteristics, where the digital modeling and additive manufacturing process enable specification of autocorrelation function and root mean square roughness parameters that cannot be controlled by traditional methods
Solution Approach 2:
The patent replaces complex multi-step traditional manufacturing processes with a single integrated 3-D printing process that combines pattern generation and texture creation, reducing the number of manufacturing steps while achieving superior precision
