Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measuring cups for household products face challenges in production speed, cost, durability of measure marks, and readability, especially in low-light conditions, due to printing, in-mold labeling, and molding limitations.
Innovation Solution
A measuring cup with a bitmapped pattern on its sidewall, created using a laser to chemically or structurally modify the surface with bits, allowing for high-speed, cost-effective, and durable mark production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If printing measure marks on plastic measuring cups is used, then the measuring cups can be produced at high speed and low cost, but the printed marks are subject to wear and tear which deteriorates the measure marks during use
Solution Approach 1:
The patent replaces the mechanical printing process with a laser marking process. The laser directly marks the plastic material to create permanent, raised relief marks that are resistant to wear and tear, while maintaining high production speed and low cost advantages.
Solution Approach 2:
The patent changes the physical state of the measure marks from printed surface patterns to three-dimensional raised relief structures. This parameter change in mark geometry provides durability while maintaining manufacturability through laser processing.
2Reliability
If molding the marks into the shape of the measuring cup is used, then the measure marks are durable and readily perceivable, but requiring specially shaped molds and making changes requires new molds which are expensive
Solution Approach 1:
The patent replaces the expensive mold-based molding process with a direct laser marking process. The laser can be programmed to create different mark patterns without requiring physical mold changes, eliminating the need for expensive mold retooling while maintaining durable, raised relief marks.
Solution Approach 2:
The patent uses digital copying of mark patterns through laser programming rather than physical copying through molds. This allows flexible changes in measure mark designs without requiring physical mold fabrication, significantly reducing the cost and time of modifications.
3Productivity
If printed marks are used on measuring cups, then production is fast and inexpensive, but the marks are difficult to perceive in certain poorly lit environments
Solution Approach 1:
The patent creates raised relief marks through laser marking that provide tactile and visual contrast against the cup surface. These three-dimensional marks are easily perceivable in various lighting conditions, including poor lighting, while maintaining fast and inexpensive production.
Solution Approach 2:
The patent replaces flat printed marks with three-dimensional raised relief marks created by laser processing. This mechanical transformation of the mark structure enhances detectability and readability across different lighting conditions without sacrificing production efficiency.
