Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing lottery systems fail to ensure non-redundancy in quick pick numbers, leading to multiple winners and reduced prize values due to the lack of tracking and generation of identical quick picks.

Innovation Solution

An apparatus and method utilizing a centralized server to create a file of all possible non-redundant number combinations, shuffle them randomly, and incrementally or decrementally generate unique quick pick entries, ensuring only one grand prize winner by sequentially updating a file index pointer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional random generation method is used for quick pick numbers, then generation speed is fast and simplicity is maintained, but redundancy occurs leading to multiple winners and reduced prize value

Engineering Contradiction:

Improveuniqueness of quick pick numbersVSAvoidcomplexity of tracking and generation system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system pre-generates all possible non-redundant quick pick number combinations and stores them in a database before the lottery draw. This preliminary action ensures that when quick pick tickets are issued, unique number sets are automatically assigned without real-time tracking complexity, resolving the contradiction between reliability and device complexity.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system creates a complete set of non-redundant number combinations in advance, serving as a cushion against the possibility of redundant assignments. By having all unique combinations pre-prepared and stored, the system guarantees uniqueness without requiring complex real-time verification mechanisms.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Reliability

If all possible combinations are generated and stored, then uniqueness is ensured, but memory requirements and data processing load increase

Engineering Contradiction:

Improveguarantee of single grand prize winnerVSAvoidamount of data to be processed and stored

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The system changes the parameter of data representation by storing pre-calculated unique combinations rather than generating them on-demand. This parameter change from dynamic generation to static storage reduces processing load during ticket issuance while maintaining the guarantee of uniqueness, balancing reliability with data management efficiency.

Inventive Principle:

Principle #35Parameter changes

AI summary

At least a method and an apparatus are provided for efficiently generating non-redundant machine-generated quick pick lottery game entries. A computer file is created that includes every possible combination of number groups eligible for being selected for a particular lottery game. The every possible combination within the file is randomly shuffled to create a randomized list of non-redundant entries. A file index with a file index pointer is assigned to the randomized list of non-redundant entries. The file index pointer is set to an initial position in the randomized list of non-redundant entries. Each non-redundant machine-generated lottery game entry is generated by only sequentially incrementing or only sequentially decrementing the file index pointer in the randomized list, and outputting the each non-redundant entry indicated by the file index pointer to a ticket request device.
