Mail Card Search System for Mobile Email Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a mobile environment, searching for specific emails using a mail application is difficult due to the challenges of typing conditions like 'sender: OOO' and 'receiver: OOO', and general keyword searches often return irrelevant results by including carbon copy, blind carbon copy, title, and content, making it hard to quickly retrieve desired emails.
Innovation Solution
A mail service system and method that allows users to quickly retrieve desired emails by setting specific items like sender and receiver as 'card items', searching for mail data with keywords, creating separate mail lists, and providing a search result with mail cards that include tags and links to these lists, enabling users to easily access relevant emails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If general keyword search is used to search for emails, then all emails containing the keyword are retrieved, but the search results include irrelevant emails (CC, BC, title, content) making it difficult to quickly retrieve desired emails
Solution Approach 1:
The patent segments the search results by creating separate mail lists for different card items (sender, receiver, attachment). Instead of presenting all matching emails in a single undifferentiated list, the system divides them into categorized groups, allowing users to quickly locate emails in specific contexts without sifting through irrelevant results.
Solution Approach 2:
The patent extracts and highlights specific card items (sender, receiver, attachment) from the general email data structure. By creating separate mail lists focused on these extracted elements, the system isolates the most relevant search results from the broader set of matching emails, improving search precision.
2Measurement precision
If typing conditions like 'sender: OOO' and 'receiver: OOO' is used to search for specific emails, then precise search results are obtained, but typing is difficult in mobile environment
Solution Approach 1:
The system performs self-service by automatically analyzing email metadata and generating structured search results without requiring users to manually type complex search conditions. The mail service system itself categorizes and organizes emails based on card items, eliminating the need for users to format search queries.
Solution Approach 2:
The patent creates a universal search interface that works across different email attributes (sender, receiver, attachment) without requiring different typing formats. A single keyword input automatically triggers multi-dimensional search and categorization, making the system adaptable to various search needs without increasing operational complexity.
3Productivity
If separate mail lists are created for different card items, then emails can be quickly retrieved based on specific criteria, but the search result structure becomes more complex
Solution Approach 1:
The patent adds a new dimension to the search result structure by organizing emails into multiple mail lists corresponding to different card items. This dimensional organization transforms a flat list of results into a multi-layered structure where emails are categorized by their relevance to specific search criteria, enabling faster retrieval through targeted navigation.

AI summary
Mail service method for searching for mail in a mail service system. At least one of a plurality of items configuring a format of mail data is set as at least one card item. A keyword is received, and for mail data that includes the keyword is searched for. A separate mail list for the at least one card item is configured by selecting mail data including the keyword in the at least one card item, and creating a mail card including a tag indicating the at least one card item and a link to the configured separate mail list. A search result that including the created mail card is provided.
