Escalator Lighting Themes Linked to Operating State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems for personnel conveying devices, such as escalators, lack user-settable lighting themes that adapt to various operating states, failing to consider the device's operational conditions.
Innovation Solution
A lighting system with a lighting device, controller, and remote operation device that allows users to select and set lighting themes based on the device's operation state, featuring personalized and predetermined themes, and includes synchronization options for speed and direction, as well as automatic brightness adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed lighting theme is used in existing lighting systems, then the system structure is simple, but the adaptability to different operating states and user preferences is poor
Solution Approach 1:
The lighting system dynamically adjusts lighting themes based on operating states (idle, running, emergency) and user preferences. The lighting controller receives real-time operating state information and automatically selects appropriate lighting themes, making the system adaptive without requiring complex manual reconfiguration for each scenario
Solution Approach 2:
The lighting system is segmented into independent functional modules: light sources, lighting device, lighting controller, and remote operation device. This modular architecture allows the system to achieve high adaptability through software control while maintaining relatively simple hardware structures, as each module performs a specific function
2Loss of information
If existing lighting systems do not consider various operating states, then the control logic is simple, but the information completeness about device status is insufficient
Solution Approach 1:
The lighting controller receives feedback signals from the personnel conveying device about its operating state (idle, running at rated speed, emergency conditions). Based on this feedback, the controller automatically selects and applies appropriate lighting themes, ensuring that lighting information accurately reflects the current device status without requiring complex manual input
Solution Approach 2:
Multiple lighting themes are pre-configured in the lighting controller for different operating states. When the device transitions to a specific operating state, the controller immediately applies the corresponding pre-prepared lighting theme, eliminating information loss about device status while avoiding the complexity of real-time lighting design calculations
3Adaptability or versatility
If users cannot set lighting themes, then the system is easy to operate, but the user experience and personalization capability are limited
Solution Approach 1:
A remote operation device serves as an intermediary between the user and the lighting controller. The user interacts with the simple remote device to select and configure lighting themes, while the remote device handles the complexity of communicating with and controlling the lighting system, thus improving user experience without significantly complicating the overall operation
Solution Approach 2:
The lighting system provides multiple lighting themes that can be universally applied across different operating states and user preferences. The remote operation device offers a unified interface for configuring various lighting parameters, allowing users to customize lighting without needing to understand the complex underlying system architecture
