Suicide Prevention Door With Movable Upper Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suicide prevention devices, such as those described in prior patents, compromise patient privacy, particularly when used as bathroom doors, as they require openings that can be exploited for hanging attempts.
Innovation Solution
An additional movable panel is integrated into the device, which collapses into the main panel when a specified weight is applied, ensuring the slanted surface of the main panel can effectively prevent hanging attempts while maintaining privacy by filling the upper space and providing a secure, private area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an opening is provided above the top surface of the panel to allow ventilation or light, then the device maintains its suicide prevention function, but patient privacy is compromised
Solution Approach 1:
The door panel is divided into two functional segments: a fixed lower panel that provides suicide prevention through its slanted surface design, and a movable upper privacy panel that can be positioned to cover the opening when privacy is needed. This segmentation allows each part to fulfill its specific function independently.
Solution Approach 2:
The upper panel is designed to be movable rather than fixed, allowing it to dynamically adjust between providing privacy coverage and allowing ventilation/light passage. The panel can be slid into place to cover the opening or removed to allow airflow, providing adaptive functionality based on privacy requirements.
2Object-affected harmful factors
If the panel is made completely solid to ensure privacy, then patient privacy is improved, but the suicide prevention effectiveness is reduced due to inability to provide ventilation
Solution Approach 1:
The door assembly is segmented into a fixed lower suicide prevention panel and a separate movable upper privacy panel. The lower panel maintains its slanted surface configuration that prevents hanging, while the upper panel can be positioned to provide privacy without interfering with the suicide prevention function of the lower panel.
Solution Approach 2:
The movable upper privacy panel acts as an intermediary element that mediates between the conflicting requirements of privacy and ventilation. When positioned to cover the opening, it provides privacy; when removed or repositioned, it allows ventilation while the lower panel continues to provide suicide prevention.
3Object-affected harmful factors
If a movable upper panel is added to provide privacy, then patient privacy is improved, but device complexity increases
Solution Approach 1:
The complexity is managed by segmenting the door into distinct functional panels: a fixed lower panel for suicide prevention and a separate movable upper panel for privacy. This modular segmentation allows each component to be simple in its own right while providing complex overall functionality when combined.
Solution Approach 2:
The upper panel employs a simple sliding mechanism that allows it to move between positioned states without requiring complex actuators or control systems. The panel can be easily slid into place to cover the opening or removed to allow ventilation, maintaining simplicity despite the added functionality.

AI summary
A sentinel event reduction door comprises a trapazoidally-shaped panel comprising four sides. A continuous hinge is connected to the panel along substantially the full length of a first side thereof. A second side of the panel adjacent to the first side is at an angle defined by the inner section of the first and second sides of the panel and is an acute angle. A second panel at the top of the door for movement between an open position to a closed position within an opening in the second side of the first panel. A third side of the first panel has a pliable material attached thereto.
