Test System Alarm Icon Prioritization for Maintenance Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle performance test systems with multiple measuring devices, maintenance management information can be obscured, making it difficult to ensure timely maintenance and potentially reducing measurement accuracy, and troubleshooting complex flow paths is challenging due to overlapping displays and information overlap.
Innovation Solution
A test system with a device management apparatus that prioritizes the display of alarm icons for sensitivity, operating time, and inspection date alerts, allowing for visual differentiation and quick identification of issues, along with a list display and locational information to facilitate troubleshooting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple measuring devices are connected to the measurement management apparatus, then the system can manage more testing devices, but the maintenance management information cannot be wholly displayed on the screen and may be covered by overlapping windows
Solution Approach 1:
The alarm information is segmented into three distinct alarm icons (sensitivity alarm, accumulated operating time alarm, and inspection date/time alarm), each representing a different type of maintenance information. This segmentation allows critical information to be separated and displayed independently, preventing it from being lost in overlapping windows while still supporting multiple testing devices.
Solution Approach 2:
The critical maintenance management information is extracted from the general display and presented as dedicated alarm icons in a fixed position on the screen. This extraction ensures that important maintenance information is always visible and cannot be covered by other overlapping display windows, directly addressing the information loss problem.
2Loss of information
If the display shows various types of information from multiple testing devices, then comprehensive monitoring is achieved, but critical alarm information may be obscured or overlooked
Solution Approach 1:
The alarm icons are given special visual prominence and placed in a fixed, easily noticeable position on the screen. This local quality enhancement ensures that critical alarm information stands out from other display elements, making it highly visible and reducing the risk of being overlooked, thereby improving maintenance timing reliability.
Solution Approach 2:
The alarm icons use visual differentiation (potentially including color changes) to indicate different alarm states and priorities. This visual encoding makes it easy to quickly identify critical information among various display elements, ensuring timely response to maintenance needs.
3Measurement precision
If the system monitors multiple parameters of testing devices, then measurement accuracy is ensured, but troubleshooting becomes difficult due to the extremely complicated flow path system
Solution Approach 1:
The alarm information is extracted from the complex system and presented in a simplified, centralized format as dedicated icons. This extraction creates a clear overview of system status without requiring operators to navigate through the complicated flow path details, making troubleshooting easier while maintaining monitoring of multiple parameters.
Solution Approach 2:
The monitoring system is segmented into distinct alarm categories (sensitivity, operating time, inspection date/time), each represented by its own icon. This segmentation allows operators to quickly identify specific problem areas without being overwhelmed by the complexity of the overall system, facilitating more efficient troubleshooting.
