Slotted Sprocket Adapter for Roller Door Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller door assemblies face challenges in ease of installation, maintenance, and cost due to the need to disconnect the non-rotating support rod, which increases installation complexity and cost.
Innovation Solution
A sprocket with a slot is positioned about the non-rotating support rod without disconnecting it, and an adjustable connector is used to attach the sprocket externally to the door-supporting frame, allowing for flexible and efficient mechanical coupling to the motor drive mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a sprocket is used to mechanically couple the motor to the door-supporting frame, then the mechanical coupling is achieved, but the non-rotating support rod must be disconnected from an installed position, increasing installation complexity and skill requirements
Solution Approach 1:
The coupling mechanism is divided into separate components: a sprocket that can be independently positioned on the support rod, and a door-supporting frame that can be independently attached to the sprocket. This segmentation allows the sprocket to be installed first without requiring disconnection of the support rod, then the frame is attached to the sprocket, simplifying the overall installation process
Solution Approach 2:
The sprocket serves as an intermediary component between the motor and the door-supporting frame. By positioning the sprocket on the support rod first and then attaching the frame to the sprocket, it mediates the coupling process and eliminates the need to disconnect the support rod from its installed position
2Manufacturing precision
If the non-rotating support rod is disconnected to install the sprocket, then the sprocket can be properly positioned, but the installation time increases and skill level requirements increase
Solution Approach 1:
The sprocket is preliminarily positioned on the support rod before the door-supporting frame is attached. This preliminary positioning can be done with basic tools and without disconnecting the support rod, saving time and reducing skill requirements while still achieving proper positioning accuracy
3Reliability
If existing mechanical coupling approaches are used, then the motor can be coupled to the door-supporting frame, but the installation cost and maintenance difficulty increase
Solution Approach 1:
The segmented design allows the sprocket to be a separate, easily replaceable component. If maintenance is needed, the sprocket can be independently accessed and replaced without requiring disconnection of the support rod or complex dismantling of the entire assembly, improving ease of repair while maintaining coupling reliability

AI summary
A sprocket having a slot formed therethrough can be disposed about the non-rotating support rod of a given roller door. This sprocket is then attached to the door-supporting frame such that the sprocket is positioned externally to the roller door. A connector can serve to effect this attachment. This connector might comprise a plurality of bolts with support sleeves. By this approach, the sprocket can be maintained at a fixed distance from the door supporting frame. This connector might also comprise an adjustable connector that adjustably and fixedly connects the sprocket with respect to the door-supporting frame. By one approach, the sprocket connects directly to the door-supporting frame. By another approach, if desired, the sprocket connects to a frame interface which connects, in turn, to the door-supporting frame. This frame interface can itself also have a slot formed therethrough to again facilitate placing the frame interface into an installed position.
