Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window security devices are not portable, damage the window or its frame when installed, do not allow partial opening, and lack aesthetic appeal, while also being difficult to remove in emergencies or for child safety.
Innovation Solution
A portable window security device with adjustable support members, jam arms, and sash blades that can be easily installed and removed, allowing partial window opening, featuring a spring-biased foot for secure attachment and quick emergency removal, and designed to prevent tampering by children and intruders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If permanent installation methods (screwing into window sash or frame) are used, then security protection is provided, but the window or frame is damaged and the device is not portable
Solution Approach 1:
The device is divided into separate modular components: a support member that fits in the window tract, jam arms that can be positioned independently, and sash blades that slide between window sashes. This segmentation allows the device to provide security without requiring permanent attachment to the window structure.
Solution Approach 2:
The support member acts as an intermediary element that fits within the window tract space rather than attaching to the window sash or frame directly. This intermediary approach provides anchorage without damaging the window structure, as the support member utilizes the existing window tract geometry.
2Reliability
If permanent installation methods are used, then security protection is provided, but the device is not portable and cannot be easily removed
Solution Approach 1:
The device consists of separable components that can be easily assembled and disassembled. The support member, jam arms, and sash blades can be independently positioned and removed, allowing the entire security device to be quickly taken down and transported without damage to the window structure.
Solution Approach 2:
The device incorporates movable and adjustable elements including telescoping jam arms with pivot points, sliding sash blades, and adjustable support members. These dynamic features allow the device to be easily configured for different window sizes and quickly installed or removed without permanent attachment.
3Reliability
If the device is designed to secure the window completely closed, then security is maximized, but the window cannot be opened for fresh air
Solution Approach 1:
The device is designed to provide partial security by allowing the window to remain open at a controlled distance rather than requiring complete closure. The jam arms can be positioned to secure the window at various opening distances, providing security while maintaining ventilation when desired.
Solution Approach 2:
The adjustable jam arms and sash blades allow the security threshold to be dynamically repositioned. Users can adjust the device to secure the window at different opening distances based on their needs, balancing security requirements with ventilation desires.
4Ease of manufacture
If fixed-length components are used, then manufacturing is simplified, but the device cannot fit various window sizes
Solution Approach 1:
The device incorporates telescoping components where inner members slide within outer members, allowing variable effective lengths from fixed-size components. The jam arms and support members can extend or retract to match different window dimensions while using standardized base components for manufacturing.
Solution Approach 2:
The device uses adjustable parameters including telescoping lengths, pivot point positions, and sash blade extensions to adapt to various window sizes. These parameter adjustments allow a single device design to fit multiple window configurations without requiring custom manufacturing for each size.

AI summary
A window security device has a support rod capable of securely contacting an upper window frame and a lower window frame. The device has two horizontal arms extending from away from the support rod terminating in thin blades capable of sliding between a first stationary window and a second sliding window sash. The device prevents unwanted tampering with the device by children located on the inside of the window as well as burglars located on the exterior of the window and to be easily removed in the event of a fire. The length of the device's blade can be adjusted allow a window to safely remain open a specified distance, and the device's arms can be adjusted to fit many different widths of windows. When the blades are disposed between the windows, the window is slid open and contacts the window stop, located at the end of the horizontal arms.
