Product Search System Using Phrase Analysis for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing product search systems using portable information processing terminals face challenges in efficiently searching and specifying target products from a large number of registered products due to cumbersome input processes and the need for frequent scrolling or page advancement, especially when products are classified hierarchically and displayed on limited screen sizes.
Innovation Solution
A product search system that includes a phrase analysis unit to divide product names into phrases and extract search words, allowing users to narrow down product lists by designating search words, thereby reducing the workload and enabling faster target product specification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hierarchical classification is used to organize products, then product organization becomes systematic, but the number of scrolling operations increases
Solution Approach 1:
The patent extracts key identifying features from product names and displays them as selectable tags or chips above the product list. This allows users to quickly filter and locate products without scrolling through the entire hierarchical classification structure, directly reducing the number of scrolling operations required.
Solution Approach 2:
The system pre-processes and displays key product identification information (such as product category, brand, or key attributes) before the user needs to search. This preliminary presentation of filtering information allows users to quickly narrow down product selections without manually navigating through hierarchical classifications.
2Ease of operation
If software keyboard is used for input, then data entry is possible, but input operation becomes cumbersome
Solution Approach 1:
The system automatically extracts and fills product information based on recognized patterns or user selections, reducing the need for manual data entry. The software identifies key product attributes and populates fields automatically, allowing users to confirm rather than type, thereby eliminating cumbersome keyboard input operations.
Solution Approach 2:
The patent replaces manual keyboard input with touch-based selection interfaces and automatic information recognition. Users interact through tapping or selecting from displayed options rather than typing, substituting mechanical keyboard operations with more efficient touch interface operations.
3Volume of moving object
If product list is displayed on limited screen, then portability is maintained, but product visibility decreases
Solution Approach 1:
The patent segments the product information display into multiple hierarchical levels or sections that can be progressively expanded. Key product identification information is displayed in a compact format initially, with detailed product lists available for expansion when needed, allowing efficient use of limited screen space while maintaining product visibility.
Solution Approach 2:
The system utilizes vertical space more effectively by implementing collapsible product categories and expandable product lists. Information is organized in a multi-dimensional layout where users can expand or collapse sections as needed, maximizing the use of limited screen real estate while maintaining full product information accessibility.

AI summary
There is provided a product search system including a user interface through which a target product can be efficiently searched and specified from a number of products registered in a product master with high speed while reducing work load. In a representative embodiment of the present invention, there are provided a phrase analysis unit which acquires a character string of a product name of each of the products contained in a list of the products, divides the character string into phrases by a predetermined division character or a symbol to acquire words, and sets a word satisfying a predetermined condition in each of the words to a search word, and a search word processing unit that shows the search word to the user, narrows the products contained in the list down to products of which the product names contain a search word designated by the user, and outputs the narrowed products.
