Segmented Dust Cover With Curved Airflow for EGM Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic gaming machines (EGMs) are complex devices with multiple access points that require regular maintenance, exposing internal components to dust and potential damage, and there is a need for a protective cover that ensures dust prevention while allowing for easy access and airflow.
Innovation Solution
A dust cover with a planar body portion, side walls, removable covers, and a curved airflow surface with a nonlinear profile is designed to protect EGM components from dust while maintaining airflow and allowing tool-free access to compartments, including heat sinks and batteries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a protective cover is installed to prevent dust accumulation, then dust protection is improved, but access to internal components becomes more difficult
Solution Approach 1:
The cover is divided into a stationary base portion and a removable access portion. The base portion remains fixed to provide continuous dust protection, while the access portion can be detached to allow maintenance personnel to reach internal components such as heat sinks and batteries without removing the entire cover structure.
Solution Approach 2:
The removable access portion acts as an intermediary element between the protective cover and the internal components. It provides a controlled access path that maintains the overall protective barrier while enabling selective access to specific components during maintenance operations.
2Object-affected harmful factors
If a sealed cover is used to prevent dust entry, then dust protection is improved, but airflow to components is restricted
Solution Approach 1:
The cover structure implements different properties in different regions: the base portion provides sealed dust protection, while the access portion incorporates openings and mesh structures that allow airflow when in the open position. This local differentiation enables simultaneous dust protection and airflow maintenance.
Solution Approach 2:
The access portion transitions between closed and open positions dynamically. When closed, it provides dust protection; when opened, it allows airflow and component access. This dynamic state change enables the system to adapt between protection and ventilation requirements based on operational needs.
3Ease of operation
If multiple access points are provided for maintenance, then ease of access is improved, but dust entry points increase
Solution Approach 1:
The cover is segmented into multiple functional zones including the base portion and separate access portions. Each access portion can be independently opened to provide targeted access to specific components, minimizing the exposure of other areas to dust while maintaining ease of maintenance for different components.

AI summary
A dust cover for an electronics assembly is provided. The dust cover may have a planar body portion having a planar top surface, a plurality of side walls extending from the planar body portion in a direction substantially perpendicular to the planar top surface and at least partially defining a plurality of compartments, a first removable cover connected to the planar body portion, positioned over a first compartment, and configured to be removable without a tool, and a curved airflow surface connected to the planar body portion. Each side wall has a proximate end connected to the planar body portion and a distal end offset from the planar body portion, the distal ends form a reference plane offset from the planar body portion, and at least a portion of the curved airflow surface is interposed between the reference plane and the planar body portion.
