Telescoping Window Guard Cable Stop Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window guards with telescoping bars lack a reliable mechanism to ensure a minimum overlap that cannot be overridden, potentially compromising their ability to withstand pressure when extended to maximum width, especially in emergency situations.
Innovation Solution
A window guard design featuring telescoping horizontal bars with a cable and stop mechanism that sets a predetermined minimum overlap, preventing the bars from being easily overridden, ensuring the guard can withstand a predetermined pressure even at maximum width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If telescoping bars are extended to maximum width, then the window guard provides greater opening access, but the overlap decreases below safe minimum levels
Solution Approach 1:
A cable is pre-installed through the telescoping bars with a stop mechanism that preliminarily sets the maximum extension point. This preliminary action ensures that when the bars are extended, they cannot exceed the predetermined minimum overlap distance, automatically preventing unsafe configurations before they occur.
Solution Approach 2:
The cable acts as an intermediary element between the telescoping bars, mediating their relative movement. The cable with its stop mechanism controls the extension distance, ensuring that the bars maintain the required overlap while still allowing adjustable width changes within safe limits.
2Reliability
If the window guard is made secure with fixed overlap, then safety is improved, but the ability to adjust width is reduced
Solution Approach 1:
The window guard transitions from a static fixed-structure to a dynamic telescoping structure with controlled movement. The bars can dynamically adjust their width within limits set by the cable stop mechanism, providing both adaptability for different window sizes and safety through predetermined minimum overlap constraints.
Solution Approach 2:
The system allows changes in the width parameter while maintaining the overlap parameter within safe bounds. The cable mechanism enables continuous adjustment of the bar extension distance, changing the width parameter dynamically while the stop mechanism ensures the overlap parameter never falls below the safety threshold.
3Ease of operation
If the cable stop mechanism is made accessible, then ease of adjustment is improved, but the risk of intentional override increases
Solution Approach 1:
The stop mechanism is nested within the hollow interior of the telescoping bars, making it inaccessible from the exterior. The cable with its stop is concealed inside the bar structure, allowing interior access for legitimate adjustment while preventing exterior access that could lead to intentional override or tampering.
