Barcode Scanning for Chat Group Member Addition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for adding a new member to a chat group are cumbersome and complex, especially for mobile users, requiring search and application processes that are inconvenient in the mobile internet era.
Innovation Solution
A computer-implemented method using a server that allows new members to join chat groups through barcode scanning or existing-member invitations, where the server receives and processes joining requests, adds members without further authorization, and sends notification messages based on the joining process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the traditional group number distribution method is used, then the group can be established and members can join, but the operation process becomes cumbersome and complex for mobile users
Solution Approach 1:
The patent uses barcode copying as a replacement for traditional group number distribution. Instead of requiring users to search for and manually enter group numbers, the group host generates a barcode that encodes the group information, which can be scanned and copied directly by potential members' mobile devices. This copying mechanism simplifies the joining process while maintaining group security through encoded information.
Solution Approach 2:
The patent replaces the manual mechanical process of typing group numbers with an optical scanning system. Mobile device cameras capture barcode images, and optical recognition technology automatically decodes the group information, eliminating the need for manual keyboard input and reducing operational complexity for mobile users.
2Productivity
If manual group number search and application process is used, then group membership can be added, but the process requires multiple steps including verification that increases operational complexity
Solution Approach 1:
The patent implements preliminary action by pre-encoding all necessary group joining information within the barcode structure before the user arrives. The barcode contains pre-prepared group identifiers and joining parameters, so when scanned, the system can immediately process the joining request without requiring real-time verification steps or manual information entry, significantly reducing the time required for group membership addition.
Solution Approach 2:
The patent extracts the essential group joining information from the complex verification process and embeds it directly into the barcode. By taking out only the necessary identification data and encoding it in the barcode, the system eliminates unnecessary verification steps while maintaining security, thereby speeding up the member addition process.
3Reliability
If traditional verification processes are used, then group security is maintained, but the multi-step verification process makes mobile operations inconvenient
Solution Approach 1:
The patent introduces an intermediary mechanism - the barcode itself - that carries encoded group information between the group host and potential members. This intermediary contains verified group identifiers and joining parameters, allowing the system to maintain security through encoded information while simplifying the user interaction to a single scan operation, thus resolving the conflict between security and ease of mobile operation.

AI summary
The current invention discloses methods and devices for adding a new member to a group, e.g. a chat group associated with a chat program. The new member may be added through a barcode-scanning process or an existing-member-invitation process. After the new member is added to the chat group, a server may send notification messages to mobile devices associated with the existing members of the group. The contents of the notification messages may vary based on the processes by which the new member is added, the number of existing members, and the direct-contact relationships the new member has with the existing members. The current invention provides simplified methods and devices for adding the new member, avoiding cumbersome operations and protecting member privacy at the same time.
