Offset Symbol Bearing Surface for High-Speed Reel Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In slot machines, it is difficult for players to spot symbols like the chaser symbol at high spinning speeds, which can reduce player enjoyment.
Innovation Solution
A mechanical reel with a symbol bearing surface offset from the reel surface, adding a third dimension to make symbols more visible, using a symbol carrier that can be pivotally mounted or tilted within apertures, and incorporating a strip of looped material with symbols on both the surface and offset bearing surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If reels spin at high speed (100 revolutions per minute), then productivity increases, but symbols become difficult to spot and player enjoyment decreases
Solution Approach 1:
The patent applies dimensionality change by offsetting the symbol-bearing surface from the reel's rotational axis, creating a third dimension. Symbols are positioned on surfaces that are radially displaced from the center, causing them to protrude outward or tilt at angles during rotation. This dimensional offset makes symbols more conspicuous and easier to track visually even at high spinning speeds, directly resolving the contradiction between fast rotation and symbol detectability
2Ease of manufacture
If symbols are placed on the flat reel surface, then manufacturing is simple, but symbols are difficult to spot during gameplay
Solution Approach 1:
Instead of placing symbols on the flat, two-dimensional reel surface, the patent positions symbols on offset surfaces that extend radially outward or tilt at angles from the reel's rotational axis. This creates a three-dimensional arrangement where symbols protrude or angle toward the player, significantly improving conspicuity and trackability without substantially complicating the manufacturing process
Solution Approach 2:
The patent applies local quality by creating specific offset regions on the reel where symbol-bearing surfaces are radially displaced or tilted, while the rest of the reel maintains its standard structure. This localized dimensional change concentrates visual attention on the offset symbol areas, making them stand out during rotation without requiring complete structural redesign of the entire reel
