Staged Search Keyword List Generation for Mobile Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current search technologies face challenges in providing an efficient and convenient search experience on smartphones with limited display space and inconvenient key input systems, as they struggle to effectively suggest complete search keywords based on partial inputs, especially for users with varying search abilities.
Innovation Solution
A system and method that provides an automatically completed search keyword list by receiving initial, middle, and ending letters from a user, using a database to generate and display progressively more specific lists, enhancing search efficiency and convenience by allowing users to input only parts of the search keyword.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional auto-complete search is used on smartphones, then search functionality is provided, but display space is insufficient and key input is inconvenient
Solution Approach 1:
The patent segments the search keyword input process into distinct stages: initial letter input, middle letter input, and ending letter input. Each stage triggers a corresponding search keyword list with progressively refined results. This segmentation allows the system to manage limited display space efficiently by showing only relevant results at each stage rather than overwhelming the user with all possible completions at once.
Solution Approach 2:
The system performs preliminary actions by providing a first search keyword list immediately after the user inputs just the initial letter. This preliminary list gives users immediate feedback and options without requiring them to type the entire keyword, thereby improving search convenience while managing display space constraints through staged information presentation.
2Loss of time
If users must input complete search keywords, then search precision is maintained, but search time increases especially for users with poor search ability
Solution Approach 1:
The system implements feedback mechanisms by providing search keyword lists at multiple stages of input. After initial letter input, users receive a first search keyword list; after middle letter input, they receive a second, more refined list. This staged feedback allows users to see relevant results early and potentially complete their search without typing the entire keyword, reducing search time while maintaining sufficient precision through progressive refinement.
Solution Approach 2:
The patent applies partial action by allowing users to obtain useful search results by inputting only part of the keyword (initial letter, or initial plus middle letters). The system provides progressively more complete keyword suggestions based on the amount of input, enabling users with poor search ability to achieve satisfactory results with minimal input effort, thus reducing search time while maintaining acceptable precision.
3Productivity
If progressive keyword completion is implemented, then search efficiency improves, but system complexity increases
Solution Approach 1:
The system segments the keyword completion process into distinct phases (initial letter stage, middle letter stage, ending letter stage), with each phase having its own search keyword list generation and display logic. This segmentation improves search efficiency by providing relevant results at each stage while managing system complexity through modular organization of the completion logic for each phase.
Solution Approach 2:
The system dynamically adjusts the level of keyword completion and the corresponding search keyword list based on the user's input progress. As users input more letters (from initial to middle to ending), the system dynamically transitions between different stages of completion, providing increasingly refined results. This dynamic approach improves search efficiency by adapting to user needs while managing complexity through state-based logic.

AI summary
A method and system for providing a search keyword list are provided. The search keyword list providing system includes an initial letter receiving unit to receive at least one initial letter from a user terminal; a list providing unit to provide a first search keyword list that contains at least one automatically completed search keyword related to the at least one initial letter; and a middle letter receiving unit to receive a middle letter related to any one of the at least one initial letter from the user terminal, wherein the list providing unit provides the user terminal with a second search keyword list that contains at least one automatically completed search keyword related to the at least one initial letter and the middle letter when receiving the middle letter.
