Flush pull door handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flush pull door handles are limited by being physically molded into doors, making them difficult to remove or replace without dismantling the door, and they do not effectively address safety concerns such as being used to secure doors with chains, which can trap individuals.
Innovation Solution
A flush pull handle assembly that includes a mounting assembly with fasteners and a pull assembly, allowing for secure affixation and easy removal from a door without modifying the door structure, featuring a design that prevents chains or other items from being used to secure the door.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flush pull handles are physically molded into doors, then the handles provide safety by preventing chain entrapment, but the handles cannot be removed or replaced without dismantling the door
Solution Approach 1:
The door handle system is divided into separate components: a mounting assembly that attaches to the door and a handle assembly that mounts to the mounting assembly. This segmentation allows the handle to be removed and replaced independently from the door, while the mounting assembly remains fixed to maintain safety functionality.
Solution Approach 2:
The handle assembly is extracted from the door structure itself and mounted separately via a mounting assembly. This extraction allows the handle to be removed without dismantling the door, while the mounting assembly remains affixed to the door to maintain the safety function of preventing chain entrapment.
2Stability of the object's composition
If flush pull handles are manufactured into doors concurrently, then the door and handle form a unified structure, but the door cannot use different handles or be modified easily
Solution Approach 1:
The system is segmented into a mounting assembly that provides the unified structure with the door, and a separate handle assembly that can be exchanged. This allows the door to maintain a stable, unified appearance while enabling handle replacement for different functionalities or aesthetics.
Solution Approach 2:
The mounting assembly serves as a universal base that can accommodate different handle assemblies. This multi-functionality allows the same mounting assembly to support various handle types, enabling adaptability while maintaining the unified door structure.
3Ease of manufacture
If outwardly extending door handles are used, then the handles are easy to manufacture and install, but they provide safety hazards by allowing chain entrapment
Solution Approach 1:
The flush pull handle design preliminarily prevents the harmful action of chain entrapment by having the handle assembly sit flush with the door surface. This configuration makes it impossible for chains to hook onto protruding handle portions, thereby preemptively eliminating the safety hazard while maintaining ease of manufacture and installation.
