Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a quick response code is used to complete operations, then the operation can be completed through scanning, but the process is inflexible and requires the code to be displayed or printed on a carrier
Solution Approach 1:
The patent replaces the mechanical QR code scanning system with an image recognition-based system. Instead of requiring users to scan predetermined QR codes, the system captures images of objects, extracts feature information, and retrieves associated note information dynamically. This substitution eliminates the need for physical code carriers and enables flexible, context-aware operations.
Solution Approach 2:
The patent changes the fundamental parameter of information representation from fixed QR code patterns to dynamic image features. By extracting features from captured images and matching them with stored note information, the system transforms the rigid QR code paradigm into a flexible image-based recognition system that adapts to various objects and contexts.
2Ease of manufacture
If a quick response code is displayed or printed on a carrier, then the code can be presented to the user, but the process becomes rigid and less flexible
Solution Approach 1:
The patent replaces the physical QR code display mechanism with an electronic image recognition system. Instead of printing codes on carriers, the system captures images digitally, processes them through feature extraction, and retrieves associated information from a database, completely eliminating the need for physical code carriers.
Solution Approach 2:
The patent creates a digital copy of the object's visual appearance through image capture and processing. Instead of requiring physical QR code carriers, the system creates a digital representation of the object's features and uses this copy to retrieve and display associated note information, enabling flexible access without physical constraints.
3Adaptability or versatility
If image recognition is used to obtain object features, then direct retrieval of note information is enabled, but additional processing steps are required compared to simple QR code scanning
Solution Approach 1:
The patent performs preliminary actions by pre-storing note information associated with object feature templates in a database before actual retrieval operations. When an object is captured, the system compares its features against pre-stored templates and retrieves associated notes, eliminating the need for real-time complex processing during the actual information retrieval moment.
Solution Approach 2:
The patent introduces an intermediary database that stores the relationship between object feature information and associated note information. This intermediary layer simplifies the processing by pre-establishing feature-note associations, allowing the system to retrieve information through comparison and matching rather than complex real-time analysis.

AI summary
A note information display method, a note information sending method, and an electronic device, and relate to the field of terminal technologies. The note information display method includes: collecting a first image, where the first image includes an image of a first object; identifying the first image to obtain first information, where the first information is feature information of the first object; sending the first information to a server; receiving first note information that corresponds to the first information and that is sent by the server; and displaying the first note information.
