List Presentation Device Adjusting Display Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties when trying to purchase products or services listed online due to facilities being fully booked or products being out of stock, as existing systems do not effectively manage stock levels, leading to inefficient information presentation.
Innovation Solution
A list presentation system that adjusts display priorities based on user selection history and stock availability, generating new list information that reduces the visibility of unsuitable items, such as those fully booked or out of stock, by lowering their display priority.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the site presents all listed products and services to users, then users have access to more options, but users waste time inquiring about fully booked facilities or out of stock products
Solution Approach 1:
The system performs preliminary actions by detecting selection patterns before users make inquiries. When a user selects multiple items in sequence, the system proactively identifies potentially unavailable items and adjusts their display priority in advance, preventing other users from wasting time on unavailable options.
Solution Approach 2:
The system uses user selection behavior as feedback to dynamically adjust list presentation. By monitoring which items users select and in what order, the system learns about availability patterns and modifies display priorities accordingly, creating a closed-loop system that continuously improves information quality.
2Device complexity
If the site does not manage stock of products or services, then the site has simpler system architecture, but the site cannot detect when products are out of stock or facilities are fully booked
Solution Approach 1:
The system performs self-service by using user selection behavior itself as the detection mechanism. Instead of requiring separate stock management systems, the system leverages the natural user interactions (selections and viewings) to infer availability status, eliminating the need for additional complex infrastructure.
Solution Approach 2:
The patent replaces traditional mechanical stock management systems with an information-based detection mechanism. Instead of using sensors, inventory trackers, or booking systems, the system substitutes these with analysis of user selection patterns and viewing behavior to detect availability status.
3Loss of information
If information about unavailable products or services is presented to users, then users have complete information, but other users also receive this information and experience frustration
Solution Approach 1:
The system applies local quality by treating each item in the list differently based on its specific availability status. Instead of uniformly presenting all items or filtering entire categories, the system individually adjusts the display priority of specific items that show signs of unavailability, maintaining information completeness while reducing frustration for individual problematic items.

AI summary
A list presentation device generates list information that is sent to a first user and includes a plurality of items each indicating a trade object, obtains an item that is selected by the first user among the plurality of items included in the list information, lowers, in a case where a first item is selected by the first user among the items included in the list information, display priority stored in a storage in association with a trade object indicated by a second item, which has been selected before by the first user among the plurality of items included in the list information, and generates new list information, which is sent to a second user, based on a transmission request from the second user and the display priority stored in the storage.
