Auto-Filter Mechanism for Search Result Refinement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Online search results often produce extensive lists of varying relevance, leading to consumer frustration and reduced transaction probability due to the difficulty in filtering and refining search results effectively.
Innovation Solution
Implementing an auto-filter mechanism that suggests or selects filters based on user selections and analysis of search results, narrowing down the search result set by focusing on attributes, conditions, and relevance, thereby reducing the complexity of the search process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If keyword-based search is used to locate products, then the search can cover a broad range of available items, but the search result list becomes extensive and difficult to navigate
Solution Approach 1:
The patent segments the extensive search result list into manageable groups based on common attributes such as price ranges, brands, categories, or other relevant dimensions. This segmentation allows users to navigate through organized subsets rather than overwhelming comprehensive lists, resolving the contradiction between broad search coverage and list manageability
Solution Approach 2:
The patent implements dynamic filtering and sorting mechanisms that adapt to user interactions in real-time. As users apply filters or sort options, the search results dynamically reorganize and refine themselves, maintaining versatility while reducing perceived complexity through adaptive response to user needs
2Quantity of substance
If extensive search results are displayed to maintain completeness, then all available options are visible, but user decision time increases and transactions are delayed
Solution Approach 1:
The patent applies preliminary filtering and pre-sorting to search results based on common user preferences and purchase criteria before presentation. By pre-organizing results according to likely user needs (such as sorting by popularity, price, or relevance), the system maintains comprehensive option availability while significantly reducing the time users need to evaluate results
Solution Approach 2:
The patent enables users to quickly change key parameters such as price range, category, brand, or other filtering criteria to rapidly narrow down extensive result sets. This parameter-based filtering allows users to maintain access to comprehensive options while efficiently reducing decision time through systematic elimination of irrelevant results
3Measurement precision
If users manually apply multiple filters to refine search results, then search precision improves, but the operation becomes more complex and time-consuming
Solution Approach 1:
The patent implements intelligent recommendation systems that automatically analyze user behavior, search history, and product attributes to suggest and apply relevant filters without requiring manual user action. The system serves itself by autonomously refining search results based on inferred user preferences, thereby maintaining high search precision while eliminating the operational burden of manual filtering
Solution Approach 2:
The patent incorporates feedback mechanisms that monitor user interactions with search results and automatically adjust filtering parameters based on this feedback. By observing which results users click, spend time on, or ignore, the system learns and adapts its filtering strategy, improving search relevance over time while keeping the user interface simple and requiring minimal active filtering input from users
Data Source
AI summary
Methods, systems, and apparatus to constrain a search are described. A selection of one or more items of a search result set by a user may be obtained. One or more attributes of the one or more selected items may be evaluated. One or more filters are identified based on the evaluated attributes.
