Self-service terminal color coding for safe maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In self-service terminals like ATMs, distinguishing between safe and hazardous touch points for maintenance and servicing is challenging, leading to increased risks of injury and damage during replenishment and servicing operations.
Innovation Solution
The implementation of a visually distinct color coding system, where primary, secondary, and tertiary visual identifiers are used to differentiate between racking handles and other touch points, ensuring easy identification and safe operation by maintenance personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple touch points are labeled to indicate safe areas, then the number of safe touch points increases, but the difficulty of distinguishing between multiple touch points increases
Solution Approach 1:
The patent applies color coding to visually differentiate between primary touch points (safe for racking operations) and secondary touch points (safe for other operations). Primary touch points are marked with one color while secondary touch points are marked with a different color, allowing maintenance personnel to quickly distinguish between different types of safe touch points without confusion.
Solution Approach 2:
The patent applies different visual identifiers to different locations on the device. Primary visual identifiers are placed on racking handles and primary touch points, while secondary visual identifiers are placed on secondary touch points. This local differentiation allows personnel to identify the appropriate touch point based on the specific operation being performed.
2Ease of operation
If visual identifiers are added to differentiate touch points, then the safety and ease of operation improve, but the device complexity increases
Solution Approach 1:
The patent uses a simple color-coding system with two distinct colors to differentiate between primary and secondary touch points. This approach provides clear visual differentiation without requiring complex identification systems, maintaining simplicity while improving ease of operation.
Solution Approach 2:
The patent segments the visual identification system into two distinct categories: primary visual identifiers for racking handles and primary touch points, and secondary visual identifiers for secondary touch points. This segmentation creates a straightforward, easy-to-understand system that reduces operational complexity.

AI summary
A self-service terminal comprising a plurality of devices is described. The devices comprise: a racking handle for moving that device from an operational position to a maintenance position; a primary visual identifier (such as a bright color) associated with the racking handle, where the primary visual identifier is common for all of the racking handles and is not used for any part of the device except a racking handle; and a secondary visual identifier associated with any other parts of the device that may be safely touched, where the secondary visual identifier is visually distinct (for example, by using a different color) from the primary visual identifier.
