Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In optical time domain reflectometers, high numbers of events require multiple operations to change the event of interest, leading to inefficient failure point checking.
Innovation Solution
An optical time domain reflectometer with a measurement unit, event detection unit, display unit, operation detection unit, and event-of-interest changing unit that allows for intuitive operation through swipe or tap gestures to scroll and highlight icons, enabling efficient selection of failure points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of events increases, then the detection capability improves, but the number of operations required to check failure points increases
Solution Approach 1:
The display unit dynamically changes its configuration based on the number of events detected. When the number of events exceeds a threshold, the display automatically switches from showing all events to showing only a partial list with navigation controls, adapting the interface to the data volume while maintaining ease of operation.
Solution Approach 2:
A cursor or highlight indicator acts as an intermediary between the operator and the event list, allowing rapid navigation through multiple events without requiring multiple button presses. The cursor visually indicates the current event and enables quick selection through simple input actions.
2Measurement precision
If the number of events increases, then the detection capability improves, but the time required to check failure points increases
Solution Approach 1:
The display unit dynamically changes its configuration based on the number of events detected. When the number of events exceeds a threshold, the display automatically switches from showing all events to showing only a partial list with navigation controls, adapting the interface to the data volume while maintaining ease of operation.
Solution Approach 2:
The system pre-organizes and pre-displays event information in a structured format with key parameters visible at a glance. Navigation structures and search functions are prepared in advance, allowing operators to quickly locate specific failure points without manual searching through all events.
3Loss of information
If all event information is displayed, then the information completeness improves, but the display complexity increases
Solution Approach 1:
The event information is segmented into hierarchical levels: a summary view showing key parameters for all events, and detailed views for individual events. The display unit can switch between showing a condensed list of all events or expanding to show detailed information about selected events, maintaining information completeness while managing display complexity.
Solution Approach 2:
Different regions of the display are assigned different levels of detail. The main event list shows essential information in a condensed format, while specific regions provide expanded details about selected events. This local differentiation allows comprehensive information to be presented without overwhelming the entire display interface.
