Stepped Quick Release Bolt for Hurricane Panel Egress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hurricane panels are typically installed and removed from outside a structure, lacking an affordable means for quick release from inside, which is a safety concern during emergencies, as they block primary egress paths and increase fire risks during power failures.
Innovation Solution
A system utilizing a stepped quick release bolt assembly and dual quick release car assemblies that allow hurricane panels to be securely attached and quickly released from within the structure, using standard installation methods without modifying existing hardware, enabling emergency egress through panel-covered openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hurricane panels are installed using standard external mounting methods, then the panels provide secure hurricane protection, but the panels cannot be quickly removed from inside the structure during emergencies
Solution Approach 1:
The mounting system is divided into separate components: a permanent external mounting structure and a removable internal release mechanism. The quick release bolt assembly separates the securing function (external) from the release function (internal), allowing panels to be securely mounted yet quickly removed from inside the structure.
Solution Approach 2:
The quick release bolt assembly acts as an intermediary mechanism between the panel and the mounting structure. It provides a controlled interface that allows secure attachment when engaged and rapid release when the internal release mechanism is activated, mediating between the permanent external mounting and the need for internal quick removal.
2Ease of operation
If expensive alternative protection systems like accordion shutters are used, then quick release from inside is possible, but the cost becomes substantially higher than basic hurricane panels
Solution Approach 1:
The quick release bolt assembly serves multiple functions: it provides secure hurricane-grade attachment when engaged, enables rapid internal release when needed, and can be integrated with standard hurricane panel mounting structures. This multi-functionality allows basic hurricane panels to achieve capabilities previously only available in expensive systems.
Solution Approach 2:
The quick release mechanism uses simple, inexpensive components such as bolts, pins, and carriages that can be easily manufactured and replaced. These components provide the necessary functionality without the complex mechanisms and high costs associated with accordion shutters or other expensive alternative systems.
3Reliability
If hurricane panels block all openings for protection, then hurricane resistance is maximized, but fire risks increase during power failures when lamps and candles are used
Solution Approach 1:
The mounting system transitions from a static permanent attachment to a dynamic system that can rapidly change state. During normal conditions, the panels remain securely mounted for hurricane protection. During emergencies requiring egress or fire safety, the internal release mechanism allows rapid transition to an open state, enabling occupants to respond to changing conditions.

AI summary
A system and method for a quick release of a second object from a first object, e.g., quick release of hurricane panels (second object) from the inside of a habitable structure (first object). A stepped quick release bolt assembly or a dual quick release car assembly may be employed. In the preferred embodiment, a pin passing through a cross bored hole in a stepped bolt disposed in a receiving structure attached to a first object is releasable in order to disconnect the second object from the first object.
