Color-Coded Industrial Control Interface for Access Privilege Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current graphical user interfaces in industrial control systems do not adequately protect operations from human error, tampering, or unauthorized access due to insufficient categorization and privilege management.
Innovation Solution
Implementing a system that uses color-based and image-based graphical representations to visually indicate user privileges and access levels, allowing for secure interaction with hardware and software components by comparing user representations with stored access levels, thereby controlling access and modification privileges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If color-based graphical representations are implemented to indicate user privileges and access levels, then user authorization and access control are enhanced, but device complexity increases
Solution Approach 1:
The patent applies color-based graphical representations to indicate different user privileges and access levels. Each operation is assigned a color that corresponds to a specific access level, allowing users to quickly understand their authorization status and the restrictions applicable to each operation without complex text or icons.
Solution Approach 2:
The system changes the visual parameter of color to encode information about access levels and modification privileges. By mapping access level parameters to color values, the system provides intuitive visual feedback about user authorization status and operational restrictions, enhancing reliability without requiring complex interface elements.
2Reliability
If operations are categorized by importance and user-access modification privileges, then access control is improved, but ease of operation decreases due to human error and tampering risks
Solution Approach 1:
The patent uses color-coded graphical representations to indicate the modification privilege level of each operation. Users can visually identify which operations they are authorized to perform based on color matching between their access level and the operation's required privilege level, reducing human error while maintaining ease of operation.
Solution Approach 2:
The color-based visual indicator acts as an intermediary between the user's access level and the operation's privilege requirements. This intermediary provides intuitive visual feedback that helps users understand their authorization status without requiring them to interpret complex permission settings or remember access level hierarchies.
3Reliability
If visual evaluation of operations is required to change device operation, then access control is enhanced, but loss of time increases due to visual evaluation requirements
Solution Approach 1:
The patent employs color-based graphical representations that provide immediate visual feedback about access levels and operation privileges. Users can quickly assess their authorization status and the restrictions applicable to each operation through color coding, significantly reducing the time required for visual evaluation compared to text-based or icon-based systems.

AI summary
Systems and methods are provided for a non-transitory computer readable medium storing instructions configured to retrieve a first list of operations for a device including a sensor, an actuator, or a combination thereof, included in an industrial control system. The instructions are also configured to display a first color for each operation in the first list of operations indicative of a modification privilege related to the respective operation.
