Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator systems lack effective monitoring solutions to detect exceptional situations, such as wear and tear, allowing for timely maintenance and spare part procurement, especially in large distances where visual cues may be overlooked.
Innovation Solution
A method utilizing a remote signaling element like a warning light, activated by sensor signals, which can be acknowledged by operators and automatically logged, combined with evaluation logic for sensor signal analysis and prediction, and an alarm system for immediate notification, ensuring timely intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional monitoring methods are used without remote signaling, then device complexity is reduced, but the ability to detect and respond to exceptional situations at a distance deteriorates
Solution Approach 1:
The patent introduces a remote signaling element as an intermediary device that receives signals from the control device and displays exceptional situations visually at a distance. This mediator allows operators to monitor elevator status without being physically present at the control device, resolving the contradiction between reliable remote detection and system complexity.
Solution Approach 2:
The patent adds a spatial dimension to monitoring by placing the signaling element at a remote location separate from the control device. This dimensional separation allows operators to detect exceptional situations from a distance, improving reliability without requiring complex remote communication systems.
2Loss of time
If continuous monitoring with immediate alerts is implemented, then response time to exceptional situations is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic monitoring where the control device checks sensor signals at regular intervals rather than continuously. The remote signaling element is activated periodically when exceptional situations are detected, reducing energy consumption while maintaining effective response time through scheduled monitoring cycles.
3Measurement precision
If detailed sensor monitoring and evaluation logic are added, then measurement precision of system state is improved, but device complexity increases
Solution Approach 1:
The patent extracts the complex evaluation logic and detailed monitoring functions into a separate control device, leaving the main elevator system simple. The control device handles sophisticated sensor signal analysis while the remote signaling element provides simple visual output, separating complexity from the core elevator mechanism.
