Glass Container Mold Texture for Concealing Aesthetic Defects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glass container manufacturing processes result in high rejection rates due to aesthetic defects, which are not effectively concealed by current parametric modeling techniques, leading to increased costs and environmental impact.
Innovation Solution
Implementing a non-parametric, non-geometric, and non-figurative bas-relief texture on the inner mold surface to reproduce irregular motifs on the outer surface, which conceal aesthetic defects and allow for efficient mass production with reduced rejections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If parametric textures are used on the mold inner surface, then manufacturing precision is improved, but aesthetic manufacturing defects become more visible and productivity deteriorates
Solution Approach 1:
The patent applies non-parametric bas-relief textures that replicate natural surface irregularities (scratches, bubbles, ripples) to camouflate aesthetic manufacturing defects. By converting the harmful effect of visible defects into a beneficial camouflating texture, the solution reduces rejected containers while maintaining production efficiency.
Solution Approach 2:
The patent applies texture only to specific regions of the mold inner surface where aesthetic defects commonly occur, rather than uniformly across the entire surface. This localized application maintains manufacturing precision in critical areas while providing defect camouflating properties in aesthetic-sensitive zones.
2Productivity
If non-parametric bas-relief texture is applied to camouflate defects, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent creates mold textures by copying and replicating natural surface irregularities and defect patterns. Rather than designing complex unique textures, the solution uses replicated natural patterns (orange peel, hammered surface, bubbles) that automatically provide camouflating properties, reducing the complexity of texture design while improving productivity.
3Productivity
If uniform texture is applied across the entire container surface, then aesthetic defects are concealed, but adaptability for labeling and decoration deteriorates
Solution Approach 1:
The patent applies texture selectively to specific regions of the container surface rather than uniformly across the entire surface. This localized texturing conceals aesthetic defects in problematic areas while leaving smooth, untextured regions available for labeling and decoration, maintaining both defect concealment efficiency and labeling flexibility.

AI summary
The invention relates to a method of automatic mass production of glass containers with texture which comprises producing a mold including a texture of non-parametric three-dimensional motifs (5) by means of protuberances, with said motifs being irregular, non-geometric, and non-figurative and being irregularly distributed; manufacturing glass containers with non-parametric texture bas-relief motifs covering and concealing potential aesthetic manufacturing defects by means of an automatic process of molten glass compression and/or blow molding; automatically detecting and rejecting the containers having manufacturing dimensional and/or safety defects.
