Automatic safety window apparatus and system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic window openers can cause the window sash to twist when opening, preventing effective ventilation in case of hazardous gas buildup, and audible alarms may not be effective for incapacitated individuals.
Innovation Solution
An automatic safety window apparatus with a remotely located alarm and transmitter unit that sends a signal to a chain actuator to open the window sash, using a chain that can exert a pushing force to prevent twisting and ensure opening, even in the presence of incapacitated individuals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If an automatic window opener pushes on one side of the window sash to open it, then the window can be opened automatically, but the window sash may twist and fail to open
Solution Approach 1:
A chain actuator is introduced as an intermediary mechanism between the motor and the window sash. The chain actuator converts rotational motion into linear pushing motion along the center line of the sash, preventing twisting while maintaining automatic operation capability
Solution Approach 2:
The window opening mechanism is segmented into distinct functional components: a motor unit, a chain actuator, and a sash connector. This segmentation allows the chain actuator to specifically address the twisting problem by providing centered pushing force, while the motor provides automated operation
2Measurement precision
If audible alarms are used to detect hazardous gases, then gas levels can be detected, but the alarm is ineffective when people are already incapacitated
Solution Approach 1:
The system performs self-service by automatically detecting hazardous gas levels through sensors and triggering window opening without requiring human intervention. This eliminates the need for incapacitated individuals to respond to audible alarms, as the system autonomously executes the safety function
Solution Approach 2:
The system incorporates feedback loops where sensors continuously monitor gas levels and automatically trigger the window opening mechanism when thresholds are exceeded, creating a closed-loop safety system that responds independently of human capability
