Security System Exit Allowance Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional home security systems require users to arm them before leaving, with a limited time frame, which can be difficult to adhere to, leading to users either rushing to exit or not arming the system, potentially triggering alarms unintentionally.
Innovation Solution
A security system that uses sensor data and user history to adjust the time allowed for exit, allowing users to leave without triggering alarms, by determining normal exit patterns and adjusting the arming time accordingly, and providing flexible operation modes such as stay, home, and away modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a preset time limit is imposed for users to exit before arming the security system, then the security system can be armed successfully, but users may rush to exit or fail to arm the system due to the difficulty of adhering to the time requirement
Solution Approach 1:
The system dynamically adjusts the exit allowance time based on user history data and detected exit patterns. Instead of a fixed preset time, the system learns how long each user typically takes to exit and provides personalized time allowances, making the system adaptable to individual user behaviors while ensuring reliable arming.
Solution Approach 2:
The system uses sensor signal data and user history data to provide feedback about detected exit patterns. This feedback mechanism allows the system to recognize when a user is taking longer than normal to exit and adjust the arming timing accordingly, preventing false alarms while maintaining security reliability.
2Reliability
If the security system arms immediately after the preset time expires, then security is maintained, but users may inadvertently trigger the alarm while still exiting the home
Solution Approach 1:
The system performs preliminary actions by detecting door openings and monitoring user exit progress before the arming time expires. When the system detects that a user is in the process of exiting (door opened but user still inside), it delays the arming action until the user has fully exited, preventing false alarms while maintaining security.
Solution Approach 2:
The system applies preliminary anti-action by refraining from triggering the alarm during the exit process. The system recognizes normal exit patterns and temporarily suspends alarm triggering during these periods, counteracting the potential harmful effect of false alarms before they can occur.
3Device complexity
If the system provides a fixed exit allowance time, then the system operation is simple, but it cannot adapt to variations in user exit patterns and durations
Solution Approach 1:
The system performs self-service by automatically learning and adapting to user exit patterns without requiring manual configuration. The system collects sensor data and user history data, analyzes exit patterns autonomously, and adjusts exit allowance times automatically, eliminating the need for complex user setup while providing personalized adaptation.
Solution Approach 2:
The system changes parameters dynamically by adjusting exit allowance times based on learned user patterns. Instead of using a fixed time parameter, the system modifies the time parameter adaptively based on sensor data and historical information, allowing simple operation with high adaptability to individual users.
