Stackable Molded Articles With Contoured Corner Segments

The patent applies local quality by creating a thickness differential at specific locations (corners) of the molded articles. The corners are made thicker than the main body portions, providing localized reinforcement exactly where damage occurs during stacking, while maintaining the overall lightweight design and aesthetic appearance of the article.

The patent implements beforehand cushioning by pre-reinforcing the corner regions with increased thickness before the articles are stacked for shipping. This proactive reinforcement prevents surface damage such as paint picking, burnishing, and cracking that would otherwise occur during handling and transportation, eliminating the need for additional protective materials.

The patent applies parameter changes by modifying the thickness parameter of the molded article at specific corner regions. The corners are formed with a greater thickness than the main body portions, creating a thickness differential that reinforces vulnerable areas. This is achieved through controlled variations in the molding process parameters rather than adding separate components.

The patent merges the reinforcement function with the existing corner geometry of the molded article. Instead of adding separate reinforcement components or attachments, the thickness differential is integrated directly into the corner regions during the molding process, combining structural reinforcement with the article's aesthetic and functional design in a single manufacturing step.
