Color-Coded 2D Code Delivery Status Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of two-dimensional code readers can lead to confusion in product management when partial deliveries are made, as the reader may incorrectly record complete delivery due to the inability to distinguish between complete and partial delivery information encoded in two-dimensional codes.
Innovation Solution
The method involves creating two-dimensional codes with specific color combinations that are readable or unreadable based on the light emitted by the reader, allowing for clear differentiation between complete and partial delivery information using original and monochrome copy sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a two-dimensional code reader is used to read the two-dimensional code on the order sheet, then the product delivery status can be automatically recorded, but the reader cannot distinguish between complete delivery and partial delivery, leading to erroneous recording
Solution Approach 1:
The patent uses color-coded two-dimensional codes where the first code uses a first color (readable by the reader) and the second code uses a second color (unreadable by the reader). This color differentiation allows the system to distinguish between complete delivery (first code readable) and partial delivery (second code readable) scenarios, resolving the measurement precision issue while maintaining automatic recording capability.
2Adaptability or versatility
If the order receiver delivers products in advance when stock is insufficient, then the customer's delivery requirement can be met, but the two-dimensional code reader cannot detect the partial delivery status
Solution Approach 1:
The patent segments the delivery information into two distinct two-dimensional codes: the first code represents complete delivery information and the second code represents partial delivery information. By separating the delivery status into distinct coded segments, the system can accurately track and record whether a delivery is complete or partial, preventing information loss while enabling flexible delivery operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach ensures accurate recording of delivery status by using color-coded two-dimensional codes that are readable only under specific conditions, preventing confusion in product management.
Implementation Method 1
a first two-dimensional code and a second two-dimensional code both configured in color on a sheet to prepare an original sheet... the first color being the same as the color of light to be emitted from the two-dimensional code reader
Implementation Method 2
the second color being a complementary color to the first color... the first two-dimensional code being readable by the two-dimensional code reader
Implementation Method 3
a monochrome copy sheet preparing step of monochromatically copying the original sheet to prepare a monochrome copy sheet

AI summary
An information exchanging method using a two-dimensional code and a two-dimensional code reader. An original sheet is prepared by writing a first two-dimensional code and a second two-dimensional code. The first two-dimensional code is readable by the code reader, whereas the second two-dimensional code is unreadable by the code reader. A monochrome copy sheet is prepared by monochromatically copying the original sheet, so that the monochrome copy sheet includes a third two-dimensional code as a monochrome copy of the first two-dimensional code and a fourth two-dimensional code as a monochrome copy of the second two-dimensional code. Accordingly, the third two-dimensional code is unreadable by the code reader, whereas the fourth two-dimensional code is readable by the code reader. Information exchange is performed by using the original sheet and the monochrome copy sheet.
