Gaming Machine Armrest Woofer and Ventilation Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gaming machines face challenges in providing enhanced sound effects to stimulate player interest and preventing heat-related malfunctions, while also requiring significant space for heat dissipation.
Innovation Solution
The gaming machine incorporates a woofer housed in the armrest to produce low-pitched sounds, which transmit vibrations to the player, and features a recessed exhaust system with vents and fans to manage heat without needing extensive space for air circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a woofer is added to output low-pitched sounds, then sound effect impact is enhanced, but device complexity increases
Solution Approach 1:
The patent combines the woofer with the existing armrest structure, merging the sound output function with the structural support element. This integration allows the woofer to be housed within the armrest without requiring additional separate speaker compartments, thereby enhancing sound effects while minimizing increases in overall device complexity.
Solution Approach 2:
The armrest is designed to serve multiple functions: it provides structural support for the player's arms and simultaneously houses the woofer for low-pitched sound output. This multi-functionality approach allows the same structural element to fulfill both mechanical and acoustic roles, enhancing sound effects without proportionally increasing device complexity.
2Temperature
If heat dissipation space is increased, then heat release efficiency is improved, but installation space requirement increases
Solution Approach 1:
The patent utilizes the vertical dimension by directing heat exhaust upward through the top surface of the cabinet, rather than requiring extensive horizontal space at the back. This dimensional change allows efficient heat dissipation while minimizing the footprint area required for installation in game arcades.
Solution Approach 2:
The patent implements localized heat dissipation features at specific areas of the cabinet (front surface and top surface with vent holes) rather than requiring uniform heat dissipation space across the entire back surface. This localized approach improves heat release efficiency while reducing overall installation space requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances sound stimulation through tactile feedback and effectively manages heat, reducing the risk of malfunctions and space requirements for installation in arcades.
Implementation Method 1
a woofer housed inside the armrest, the woofer for outputting low pitched sounds based on a signal from the processor
Implementation Method 2
a vibration system (for instance, a diaphragm, etc.) of the woofer has a long stroke design so that the woofer is specialized in outputting low-pitched sounds. Accordingly, when outputting low-pitched sounds with the woofer built in the armrest, vibrations produced by the output of the low-pitched sounds are transmitted to the armrest.
Implementation Method 3
an exhaust fan which exhausts air from inside the cabinet to outside through the vent holes
