Server Device Lottery Information Conversion Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lottery systems are limited in their ability to utilize various types of information for determining winning outcomes, often requiring specific formats like two-dimensional barcodes and lacking flexibility in input sources and formats.
Innovation Solution
A server device, program, and terminal device system that performs predetermined conversion processing on arbitrary input information, allowing it to be compared with winning information for determining lottery results, thereby enabling the use of diverse information types without the need for pre-recorded lottery information on barcodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lottery information is pre-recorded on two-dimensional barcodes, then the lottery system can determine winning outcomes, but the system is limited to specific formats and requires dedicated barcodes for each lottery instance
Solution Approach 1:
The patent introduces a server device as an intermediary that performs conversion processing on input information. Instead of requiring pre-printed barcodes, the server converts arbitrary input information (URLs, text strings, etc.) into lottery-determinable formats dynamically. This mediator resolves the contradiction by enabling versatile information types while centralizing the conversion logic to maintain system manageability.
Solution Approach 2:
The patent changes the parameter of information format from fixed (pre-recorded barcode) to variable (arbitrary input information that undergoes conversion). The server device transforms input information through conversion processing, allowing different types of information (URLs, text, numbers) to be used as lottery inputs. This parameter change enables versatility while the standardized conversion process maintains system simplicity.
2Reliability
If dedicated two-dimensional barcodes are used for lottery information, then winning determination can be performed, but fraud countermeasures are insufficient and information sources are limited
Solution Approach 1:
The patent performs conversion processing in advance on the server side before lottery determination. By pre-converting arbitrary input information into a standardized format and storing it on the server, the system establishes a reliable baseline for comparison. This preliminary action enhances fraud prevention while accepting diverse input sources, as the conversion creates a unique, verifiable representation of the original information.
Solution Approach 2:
The server device performs multiple functions: it accepts various input formats (URLs, text, numbers), performs conversion processing, stores converted information, and conducts lottery determination. This multi-functional approach eliminates the need for dedicated barcodes while maintaining reliability through centralized control and standardized conversion processes.
3Adaptability or versatility
If lottery information is converted and stored on the server device, then various types of information can be used for lottery, but processing and conversion operations are required
Solution Approach 1:
The server device performs conversion processing in advance when receiving input information, converting it to a standardized format and storing it for later lottery determination. This preliminary conversion eliminates the need for real-time processing during lottery execution, improving overall productivity while enabling versatile information types to be accepted as input.
Data Source
AI summary
A server device including: a memory configured to store lottery information, winning information, and computer-readable instructions; and a processor. The lottery information is obtained by conversion processing for input information that is input via an input interface in a terminal device of a user. The winning information is a predetermined character string. The processor is configured to execute the computer readable instructions to determine whether the lottery information matches the winning information, to create lottery result information, and to transmit the lottery result information to the terminal device according to the determination.
