Two-Dimensional Code Display System with Intermittent Logo Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-dimensional code display technologies face challenges in maintaining readability, especially when a logo or image is displayed alongside the code, and they struggle to adapt to varying user environments effectively.
Innovation Solution
A two-dimensional code display system and method that dynamically change the display form of the code by intermittently showing a logo or image, varying the proportion and shape of colored patterns, and adjusting the size and aspect ratio of the code over time, allowing for seamless transitions between different content representations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a logo mark or image is additionally displayed alongside the two-dimensional code, then the design characteristic is improved, but the readability of the two-dimensional code deteriorates
Solution Approach 1:
The patent applies periodic action by alternately displaying the logo mark/image and the two-dimensional code in time-division multiplexing. The display control unit switches between showing only the logo/image and showing only the two-dimensional code at different time intervals, allowing both elements to be displayed without spatial overlap. This resolves the contradiction by separating the display in time rather than space, maintaining both design characteristics and code readability.
Solution Approach 2:
The patent implements dynamics by making the display content changeable over time. The display control unit dynamically switches the displayed content between logo/image and two-dimensional code based on timing signals. This dynamic time-division approach allows the system to adapt between presenting visual information and presenting machine-readable information, resolving the static contradiction between design and readability.
2Measurement precision
If the two-dimensional code is displayed with high readability requirements, then the readability is improved, but the adaptability to different user environments deteriorates
Solution Approach 1:
The patent applies universality by making the display system multi-functional. The same display device can serve both as a visual information display (logo/image) and as a machine-readable code display. By using time-division multiplexing, the system becomes adaptable to different user environments - whether the user needs visual branding or code scanning, the system can provide the appropriate function at the appropriate time, enhancing versatility while maintaining readability when code display is active.
3Adaptability or versatility
If the display is continuously changed between logo and code, then the adaptability is improved, but the loss of time for code recognition increases
Solution Approach 1:
The patent applies periodic action with controlled timing to minimize recognition time loss. The display control unit uses predetermined time intervals to switch between logo and code display, ensuring that each code display episode lasts long enough for recognition. The periodic nature allows scanning devices to capture the code within each display cycle without requiring continuous display, thus adapting to different environments while limiting time loss through optimized switching intervals.

AI summary
A two-dimensional code display system (1) has a display unit (4) which can display a two-dimensional code representing predetermined information by plural cells arrange in a matrix, and a control unit (2) which changes the display form of the two-dimensional code. For example, after 0.5 second has elapsed since the display unit (4) starts displaying the image of a logo mark, the control unit (2) controls the display unit (4) to change the display from the image of the logo mark to a two-dimensional code. After 2.0 seconds has elapsed since the display unit (4) starts displaying the two-dimensional code, the control unit (2) controls the display unit (4) to change the display from the two-dimensional code to the image of the logo mark. By repeating such control, the control unit (2) can control the display unit (4) to display alternately the image of the logo mark and the two-dimensional code.
