Lottery Ring Dual-Ring Relative Rotation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lottery rings used in games like roulette lack a mechanism to uniformly distribute winning rates due to component tolerance and assembly errors, leading to potential bias in lottery outcomes.
Innovation Solution
A dual-ring system where the award ring and pocket ring are concentrically arranged, allowing for relative rotation between them, which changes the correspondence of pockets with associated privileges, thereby adjusting the winning rates to achieve uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-ring lottery system is used, then the structure is simple, but component tolerance and assembly errors cause non-uniform winning rates
Solution Approach 1:
The lottery ring is divided into two independent concentric rings: a first ring with accommodating units for lottery media and a second ring with information providing units for privileges. This segmentation allows each ring to be manufactured and assembled separately, then combined through relative rotation to achieve uniform winning rates, eliminating the problem of non-uniform distribution in single-ring systems.
Solution Approach 2:
The patent introduces a dynamic relative rotation mechanism between the first ring and second ring. The rings can rotate relative to each other to change the correspondence between accommodating units and information providing units. This dynamic adjustment enables the system to compensate for manufacturing tolerances and assembly errors, ensuring uniform winning rates across different positions.
2Manufacturing precision
If relative rotation mechanism is added to adjust winning rates, then winning rate uniformity is improved, but device complexity increases
Solution Approach 1:
The patent merges the lottery media storage function (first ring) and the privilege information display function (second ring) into a single integrated dual-ring structure. Both rings share the same center and rotate together as a unified assembly, eliminating the need for separate adjustment mechanisms while achieving winning rate uniformity through their relative rotation capability.
Solution Approach 2:
The dual-ring structure serves multiple functions: the first ring accommodates lottery media, the second ring provides privilege information, and their relative rotation mechanism simultaneously achieves both media presentation and winning rate uniformity. This multi-functionality reduces the need for additional separate components, offsetting the inherent complexity of the dual-ring design.
3Ease of manufacture
If traditional single-ring structure is used, then assembly is simple, but assembly errors lead to biased lottery outcomes
Solution Approach 1:
The first ring and second ring are separately manufactured with pre-defined positions of accommodating units and information providing units respectively. This preliminary preparation allows for quality control and verification before final assembly. During assembly, the rings are combined through relative rotation to ensure proper correspondence, preventing assembly errors from affecting lottery fairness while maintaining relatively simple assembly procedures.

AI summary
A lottery ring includes a first ring and a second ring that have a ring shape and are concentrically arranged so as to form a layer; and a constraining device that operates between a constraint state for constraining the first ring and the second ring such that the first ring and the second ring integrally rotate on the same center and a release state for releasing the constraint state such that the first ring and the second ring relatively rotate, wherein accommodating units that accommodate a physical lottery medium are provided at the first ring along a rotation direction, and information providing units that are arranged along the rotation direction so as to respectively correspond to the accommodating units through the layer, and associated respectively with predetermined information is provided at the second ring.
