Product Providing Device with Inventory-Aware Lottery Options
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In online lottery systems, users cannot monopolize options like tangible lottery boxes or tickets, leading to inefficiencies in selection and management, especially with multiple participants.
Innovation Solution
A product providing system that includes an inventory managing unit, an option presenting unit, and a product providing unit, which manages inventory statuses, presents options based on search conditions, and provides products through a lottery system, ensuring efficient selection and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If users can select options freely in an online lottery system, then user participation and selection efficiency are improved, but the risk of option monopolization and inventory management complexity increases
Solution Approach 1:
The system performs preliminary actions by searching for options that satisfy search conditions based on inventory statuses before users make selections. The option presenting unit proactively filters and presents only available options, preventing monopolization issues before they occur and simplifying inventory management through advance preparation of valid options.
2Adaptability or versatility
If the system presents all options to users, then user choice and participation are improved, but the system cannot prevent selection of already selected options
Solution Approach 1:
The system implements feedback by continuously monitoring inventory statuses and using this information to filter options presented to users. The option presenting unit receives feedback from the inventory managing unit about which options are still available, and adjusts the presented options accordingly, ensuring users only see selectable options while maintaining their choice among valid alternatives.
3Measurement precision
If the system monitors inventory statuses for all options, then option selection accuracy is improved, but system complexity and processing requirements increase
Solution Approach 1:
The inventory managing unit serves multiple functions simultaneously: it tracks inventory statuses, provides this information to the option presenting unit for filtering, and enables the product providing unit to make accurate lottery selections. This multi-functionality reduces overall system complexity by consolidating inventory management tasks into a single versatile component rather than requiring separate mechanisms for each function.

AI summary
A product providing device (1) capable of communicating with a terminal (2) of a user includes an inventory managing unit (116) that manages inventory statuses of products in a product group including a plurality of types of products, an option presenting unit (112) that presents to the terminal (2) a plurality of options associated with the product group in such a manner that the user is able to select an option, and a product providing unit (117) that provides, by a lottery, a product from the product group associated with the option. The option presenting unit (112) searches for, based on the inventory statuses of the products, an option that satisfies a search condition, and presents the option that satisfies the search condition.
