URL Shortening in Messaging via Database Lookup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Internet communication, messages with limited lengths often struggle to accommodate longer Uniform Resource Locators (URLs), leading to insufficient space for user input due to the lack of URL length restrictions, which results in message length exceedance.
Innovation Solution
A method and system that detect the presence of a first URL in a message, replace it with a shorter second URL, and save the corresponding relationship, ensuring the second URL takes up minimal space while allowing users to add more content, and provide the original URL upon request.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a longer URL is inserted into a message with limited length, then the URL can be completely included in the message, but the remaining space for user input becomes inadequate and the message length may exceed the limitation
Solution Approach 1:
The patent extracts the URL from the message content and stores it separately in a database. The message itself only contains a reference identifier (such as a hash or truncated version) that links to the stored URL, thereby removing the space-consuming full URL from the message while preserving access to the complete URL information.
Solution Approach 2:
The patent introduces a database as an intermediary between the message and the URL. The database stores the complete URL information, while the message contains only a reference to this stored information. This intermediary structure allows the message to remain short while still providing access to the full URL through the database lookup.
2Adaptability or versatility
If there are no limitations on URL length, then URLs can be completely included in messages, but messages with limited length cannot accommodate these URLs
Solution Approach 1:
The patent segments the URL information into two parts: a compact reference identifier that fits within the message length limitation, and the complete URL information that is stored separately in the database. This segmentation allows the message to adhere to length constraints while the URL itself maintains its full length flexibility.
Solution Approach 2:
The patent moves the URL storage from the traditional one-dimensional message field to a two-dimensional structure where the message contains a reference and the database stores the complete information. This dimensional change allows the message to remain short while the URL information is preserved in an additional storage dimension.

AI summary
A method and system for providing a message including a URL. The method includes: detecting whether a first URL is included in message content within a message input by a user; if the first URL is included in the message content, calculating the length of the message by taking a first length value as the length of the first URL; if the calculated message length is less than the predetermined message length, allowing the user to keep on adding message content to the message; replacing the first URL included in the message by a second URL, and saving corresponding relationship between the first URL and the second URL. The length of the second URL is less than or equal to the first length value; providing the message including the second URL.
