Solution Overview
Problem
Existing measuring cups for household products face challenges in producing durable, easily perceivable measure marks that are cost-effective and can be easily changed, with printing and molding methods being slow, prone to wear, and requiring expensive specialized equipment.
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 production and durable, easily readable markings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If printing measure marks on plastic measuring cups is used, then the measure marks can be applied to the cup surface, but the process is slow and printing on curved shapes is technically challenging
Solution Approach 1:
The patent replaces traditional mechanical printing methods with laser marking technology. The laser beam directly marks the measure lines on the plastic measuring cup surface, eliminating the need for printing machinery and curved surface printing tools. This substitution of mechanical systems with optical/thermal fields resolves the contradiction by enabling both easy application and high-speed production.
2Ease of manufacture
If printed marks are used on measuring cups, then measure marks can be applied, but they are subject to wear and tear which may deteriorate the measure marks during use
Solution Approach 1:
The patent changes the physical state and chemical composition of the measure marks through laser treatment. The laser marking process modifies the plastic material at a microscopic level, creating permanent, raised or etched marks that are integral to the cup structure. This parameter change transforms the marks from surface-level printed layers to durable, wear-resistant features that maintain their integrity during washing and use.
3Reliability
If molding the marks into the shape of the measuring cup is used, then durable marks can be achieved, but it requires specially shaped molds and making changes requires new molds which are expensive
Solution Approach 1:
The patent replaces complex mechanical molding systems with a simpler laser marking process. Instead of requiring specially shaped molds for each measure line configuration, the laser can be programmed to mark any pattern directly on the cup surface. This substitution eliminates the need for expensive, specialized molding equipment while achieving durable, permanent marks.
4Reliability
If molded measure marks are used, then durable marks can be achieved, but they may be challenging for the user to perceive in certain poorly lit environments
Solution Approach 1:
The patent incorporates color or optical property changes in the laser marking process. The laser can create marks with different optical characteristics than the base plastic material, such as darker colors, contrasting hues, or optical enhancement properties. These color changes improve visibility in various lighting conditions while maintaining the durability of the molded mark structure.
