Panic Exit Door Handle with Arcing Pivot Brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a door handle system that can actuate a latch mechanism to quickly open a glass door during emergency conditions, providing a panic exit solution that is both efficient and securely mounted.
Innovation Solution
The panic exit device features an interior door handle with a horizontal and vertical component, pivotally mounted to the door using arcing pivot brackets and pins, allowing for easy installation and operation, along with a locking mechanism that can be actuated from the exterior for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a traditional fixed exterior handle is used to provide symmetrical appearance, then the aesthetic quality is improved, but the ease of operation is worsened because it cannot be actuated from the exterior for emergency exit
Solution Approach 1:
The patent applies the dynamics principle by making the exterior handle movable rather than fixed. The exterior handle can pivot between a retracted position (when not in use) and an extended position (when actuation is needed), allowing the door to be opened from the exterior in emergency situations while maintaining a clean appearance when not in use.
Solution Approach 2:
The patent applies the universality principle by designing the exterior handle to serve multiple functions: it provides aesthetic appearance when retracted, enables exterior door opening when extended, and can be positioned in intermediate states for various operational requirements. This multi-functional design resolves the contradiction between appearance and operational capability.
2Ease of manufacture
If the door handle is mounted with fixed brackets, then the manufacturing simplicity is improved, but the adaptability is worsened because it cannot be adjusted for different door configurations
Solution Approach 1:
The patent applies the dynamics principle by making the bracket system adjustable rather than fixed. The brackets can be positioned at different locations and orientations to accommodate various door configurations and mounting requirements, while still maintaining a relatively simple installation process through the pivot mechanism.
Solution Approach 2:
The patent applies the segmentation principle by dividing the mounting system into separate adjustable components. The brackets are designed as independent units that can be individually positioned and secured, allowing for adaptability to different door configurations while maintaining manufacturing simplicity through modular assembly.
3Reliability
If the handle requires complex mounting hardware, then the reliability of mounting is improved, but the ease of installation is worsened
Solution Approach 1:
The patent applies the dynamics principle by using a pivot mechanism that allows the handle to be easily installed and removed while maintaining secure mounting during operation. The pivot brackets can be quickly positioned and secured, providing reliable mounting without requiring complex installation procedures.

AI summary
An exit device comprises an inner door handle adapted to be mounted to a door for movement relative to the door from a first position to a second position. A pair of brackets are adapted to be operatively connected between the respective ends of a horizontal portion and a vertical portion of the door handle. Each bracket comprises a first bracket member secured to the door handle, a second bracket member adapted to be secured to the door, and a pin for joining the first bracket member and the second bracket member for rotation about an axis through the pin. The first bracket member and the second bracket member pivot relative to one another when the door handle moves between the first position and the second position.
