Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing garden hoses lack a durable and cost-effective QR code that remains readable after use, and industrial hoses with QR codes are difficult to manufacture.
Innovation Solution
A flexible hose with a QR code printed using hot transfer ink on a polymeric surface, compatible with the hose material, ensuring high abrasion resistance and easy readability, even when damaged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a QR code is printed on a decorative element in the package, then the QR code can be read initially, but the decorative element is thrown away after opening and the QR code becomes inaccessible
Solution Approach 1:
The patent merges the QR code directly onto the hose body by printing it on the outer polymeric layer during the manufacturing process, eliminating the need for separate decorative elements. This ensures the QR code remains permanently attached and accessible while simplifying the overall manufacturing process by integrating it into the existing production line.
Solution Approach 2:
The outer polymeric layer of the hose serves multiple functions: it provides structural protection, enables flexibility, and acts as a substrate for the QR code print. This multi-functionality eliminates the need for separate decorative elements while maintaining QR code readability throughout the hose's service life.
2Reliability
If a QR code is engraved and filled with ink on an industrial hose, then the QR code has high abrasion resistance, but the manufacturing process is slow and difficult
Solution Approach 1:
The patent replaces the mechanical engraving and manual/filling process with a direct printing method applied to the outer polymeric layer. This substitution maintains abrasion resistance through proper ink formulation and curing while dramatically increasing manufacturing speed and eliminating complex multi-step processes.
Solution Approach 2:
The patent changes the approach from mechanical engraving to thermal or chemical printing processes that can be applied directly to the polymeric surface. By adjusting printing parameters such as temperature, pressure, or ink composition, the method achieves comparable or superior abrasion resistance while significantly improving production efficiency.
3Ease of manufacture
If a simple print method is used for the QR code, then the manufacturing is cost-effective, but the QR code may not have sufficient abrasion resistance
Solution Approach 1:
The patent uses a composite approach by selecting ink materials specifically formulated to bond with and resist abrasion on polymeric surfaces. The combination of the outer polymeric layer and specialized ink creates a durable composite structure that maintains QR code readability despite exposure to weather, handling, and wear, while keeping the printing process simple and cost-effective.
