Instant Messaging Friend Segmentation for Non-Blocking Chat Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing instant messaging services lack the ability to distinguish between different types of friends, specifically addressing the challenges of removing elemental mercury (Hg0) from flue gas and oxidized mercury (Hg2+), with existing technologies being costly and their efficiency affected by NOx and SO2.
Innovation Solution
Utilization of metal sulfides (e.g., FeS2, CuS, CuFeS2) as mercury removal adsorbents, which contact with flue gas and waste liquid, adsorbing and converting Hg0 from flue gas and Hg2+ from waste liquid into stable mercury sulfide compounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If chat messages from all friends are displayed uniformly, then all users can receive messages, but users cannot distinguish between different friend types and promotional content becomes indistinguishable from personal messages
Solution Approach 1:
The patent segments friends into different types (first type and second type) and applies different display rules for their chat messages. Messages from second type friends are displayed without overlaying the user input window, while messages from first type friends use the conventional overlay display. This segmentation allows users to distinguish between personal messages and promotional/advertising messages from second type friends.
2Ease of operation
If user input window is always overlaid on chat window, then users can easily reply to messages, but messages from second type friends interfere with user input capability
Solution Approach 1:
The patent applies different display qualities to chat messages based on the sender type. For messages from second type friends, the system uses a non-overlay display mode that does not block the user input window, while messages from first type friends use the conventional overlay mode. This local quality differentiation ensures that promotional messages do not interfere with user input capability while maintaining ease of operation for personal messages.
3Adaptability or versatility
If all friends are treated equally, then the system is simple to manage, but users cannot receive targeted information based on location and interest
Solution Approach 1:
The patent implements a dynamic friend management system where friends can be classified into different types based on their characteristics, location, and user interests. The system dynamically adjusts message display behavior based on the sender type, and allows users to add second type friends through recommendations based on matching criteria. This dynamic approach enables targeted information delivery while adapting to user needs.
4Productivity
If second type friends can send messages to all registered friends, then promotional content reaches wide audience, but users receive unwanted messages from friends they don't know
Solution Approach 1:
The patent implements a recommendation-based friend addition system where second type friends are recommended to users based on matching criteria such as location and interests. Users can selectively add recommended second type friends, and once added, these friends can send messages to the user. This feedback mechanism ensures that promotional content reaches only interested users who have actively chosen to receive such messages, reducing unwanted communications while maintaining transmission efficiency.

AI summary
Provided is a technique for transmitting and receiving a chat message through a message server. A user may transmit and receive a chat message to and from a friend of a first type and may receive a chat message from a friend of a second type, and receive various chat messages from a company supporting the friend of the second type.
