Elevator Door Control Using 3D Object Grouping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems lack effective security monitoring, intelligence, user-friendliness, reliability, and user experience, particularly in managing the loading of to-be-carried objects based on their identification and grouping.
Innovation Solution
An elevator door control system utilizing three-dimensional sensors to capture and process data on to-be-carried objects, grouping them by features like height and shape, and controlling the elevator door operations to ensure that objects within the same group, such as adults, juveniles, and pets, are loaded together, while managing crowdedness and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional elevator door control is used, then the system is simple and reliable, but it lacks intelligence and user-friendliness in managing to-be-carried objects
Solution Approach 1:
The patent replaces traditional mechanical door control with an intelligent control system that uses three-dimensional sensors to detect to-be-carried objects, processes their data to identify groups, and automatically controls door operations based on grouping results, thereby achieving intelligence and user-friendliness while managing system complexity through automated decision-making
Solution Approach 2:
The system automatically detects, groups, and controls door operations without requiring manual intervention. The three-dimensional sensors continuously monitor the waiting region, the data processing device automatically groups objects based on their characteristics and positions, and the control device autonomously manages door opening and closing, enabling the system to serve itself and improving user-friendliness
2Reliability
If no grouping identification is used, then the system is simple, but safety risks increase due to inability to manage to-be-carried objects effectively
Solution Approach 1:
The system uses three-dimensional sensors to continuously detect the positions and characteristics of to-be-carried objects, processes this information to identify groups, and adjusts door operations based on the grouping results. This feedback loop ensures that door control is dynamically adapted to the actual presence and grouping of objects, significantly improving safety while managing complexity through automated real-time processing
Solution Approach 2:
The system performs preliminary detection and grouping of to-be-carried objects before door operation occurs. By identifying groups in advance and determining which objects should be loaded together, the system prevents unsafe door operations and ensures that only appropriately grouped objects are transported, thereby enhancing safety through proactive rather than reactive control
3Ease of operation
If manual door control is used, then operation is simple, but user experience is poor due to inability to ensure objects within same group are loaded together
Solution Approach 1:
The system automatically performs detection, grouping, and door control without requiring user intervention. The three-dimensional sensors continuously monitor the waiting region, the data processing device automatically groups objects based on their characteristics and spatial relationships, and the control device autonomously manages door opening and closing, eliminating the need for manual operation and significantly improving user experience through intelligent automation
Solution Approach 2:
The patent replaces manual door control with an automated intelligent system that uses three-dimensional sensors to detect objects, processes their data to identify groups, and automatically controls door operations based on grouping results, thereby achieving superior user experience while managing the trade-off between automation and operational simplicity
