Engineering Contradiction Analysis
1Reliability
If the number of scenario detection modules is increased to comprehensively monitor escalator safety, then the monitoring coverage and safety detection capability are improved, but the computing capability requirement of the monitoring apparatus increases significantly
Solution Approach 1:
The patent divides the scenario detection modules into different groups based on their monitoring functions and activates them selectively according to escalator running direction. Instead of running all detection modules simultaneously, the system segments the monitoring tasks and activates only the necessary subsets, thereby reducing overall computing resource consumption while maintaining comprehensive safety coverage.
Solution Approach 2:
The patent implements dynamic activation of scenario detection modules based on real-time escalator running direction. The system dynamically adjusts which detection modules are active - for example, activating different modules for upward versus downward running directions - rather than maintaining a static configuration. This dynamic approach ensures adequate monitoring coverage while optimizing computing resource utilization.
2Reliability
If all scenario detection modules are activated simultaneously to ensure comprehensive monitoring, then the safety detection capability is improved, but the system resource consumption and processing overhead increase
Solution Approach 1:
The patent applies partial action by activating only the necessary subset of scenario detection modules based on escalator running direction rather than all modules simultaneously. This approach provides sufficient safety detection capability for each specific operating condition without the excessive resource consumption that would result from activating all modules in every scenario.
Solution Approach 2:
The patent changes the operational parameters of the detection system by dynamically adjusting which modules are active based on running direction parameters. This parameter-based control allows the system to adapt its resource consumption profile to the actual monitoring requirements of each operating condition, reducing energy waste while maintaining detection effectiveness.
3Productivity
If scenario detection modules are selectively activated based on running direction to reduce computing load, then the computing resource efficiency is improved, but the system complexity for managing module states increases
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously monitors the escalator running direction and automatically adjusts the activation state of detection modules accordingly. This feedback-based control simplifies state management by using a clear, observable parameter (running direction) to drive module activation decisions, reducing the complexity of manual or ad-hoc state management while maintaining high computing resource efficiency.
