Flush Pull Handle Mounting Brace Assembly for Removable Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flush pull door handles are limited as they are physically molded into the doors, making them difficult to remove or replace without dismantling the door, and they require concurrent manufacturing with the door, limiting flexibility and safety in preventing doors from being improperly secured.
Innovation Solution
A flush pull door handle assembly that can be affixed and readily removed from a door without disassembling it, featuring a mounting assembly with fastener elements that secure within the door's bracing assembly, allowing for easy installation and removal without altering the door's structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flush pull door handles are physically molded into the doors, then the handles are securely fixed and cannot be easily removed or replaced, but this requires dismantling the door for installation and removal, increasing complexity and reducing flexibility
Solution Approach 1:
The door handle system is divided into separate components: a mounting brace assembly that attaches to the door and a handle assembly that attaches to the mounting brace. This segmentation allows the handle to be installed and removed independently without dismantling the door structure, while still providing secure fixation through the multi-component attachment system.
Solution Approach 2:
The mounting brace assembly is pre-installed on the door with bracing members that extend into the door's interior cavity. This preliminary action creates a prepared mounting structure that simplifies subsequent handle installation and removal, eliminating the need to dismantle the door for handle replacement.
2Ease of manufacture
If flush pull door handles are physically molded into the doors during concurrent manufacturing, then the handles are permanently integrated, but this limits flexibility for replacement and requires the door to always require that specific handle
Solution Approach 1:
The system separates the handle assembly from the door structure through an independent mounting brace assembly. This allows different handle assemblies to be interchangeably mounted on the same door using the same mounting brace, providing versatility and replacement flexibility while maintaining ease of manufacture for the mounting structure.
Solution Approach 2:
The mounting brace assembly serves as a universal interface between the door and various handle assemblies. The standardized mounting interface with multiple fastener elements allows different handle designs to be attached to the same mounting brace, making the mounting structure multi-functional and adaptable to different handle configurations.
3Ease of manufacture
If outwardly extending door handles are used, then the handles are easy to manufacture and install, but they provide hooking mechanisms that can be used by malfeasant actors to apply chains and prevent doors from being opened
Solution Approach 1:
The harmful protruding feature is extracted by transitioning from outwardly extending handles to a flush pull design where the handle surface is coplanar with the door surface. This eliminates the protruding geometry that could be used for hooking chains, while maintaining the essential pulling function through a recessed cavity design.
Solution Approach 2:
The flush pull handle design proactively prevents the harmful action of chain application by eliminating the geometric possibility of hooking. The coplanar surface and recessed cavity create a physical barrier that prevents chains from being applied, addressing the safety vulnerability before it can be exploited.

AI summary
The present invention includes a door having a first horizontal frame member with a rear wall, a front wall, and an interior cavity extending between the rear wall and the front wall, the front side having an aperture granting access to the interior cavity and to the rear wall of the first horizontal frame member. The door includes a first brace member secured to form a first side of the bracing assembly. The door includes a first vertical frame member securely engaged to the first horizontal frame member. Therein, the door includes a second brace member secured to the first side of the first vertical frame member and the first horizontal frame member to form a second side of the bracing assembly. The door includes a mounting assembly affixable within the bracing assembly. Whereupon, a pull assembly is affixable to the mounting assembly.
