Flexible Screw Alignment Sleeve for Door Knob Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The alignment of screws through apertures in door knob base plates with threaded apertures in mounting sleeves is often difficult due to limited visibility, leading to wasted time and frustration during installation.
Innovation Solution
A flexible collapsible sleeve with flared ends is used to assist in aligning screws, providing improved visibility and ease of installation by compressing to fit between the door knobs and securely fastening them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional door knob installation methods are used without alignment assistance, then the installation process requires no additional tools, but the alignment of screws with threaded apertures becomes difficult and time-consuming
Solution Approach 1:
The patent introduces an alignment sleeve as an intermediary tool that fits between the door knob components during installation. This sleeve provides visual alignment indicators and physical guidance to help the installer align screws with threaded apertures accurately, directly resolving the alignment difficulty without adding complex mechanisms.
Solution Approach 2:
The alignment sleeve incorporates visual indicators (such as colored markings or transparent sections) that allow the installer to see the alignment status of screws relative to threaded apertures. This visual feedback mechanism transforms the invisible alignment problem into a visible one, enabling quick and accurate positioning.
2Manufacturing precision
If a rigid alignment tool is used, then precise alignment can be achieved, but the tool cannot adapt to constrained installation spaces between door knobs
Solution Approach 1:
The alignment sleeve is designed with flexible or collapsible characteristics that allow it to dynamically adapt its shape and size. It can be compressed to fit into the constrained space between door knobs during installation, then expand to provide full alignment functionality, thereby combining precision with adaptability to tight spaces.
Solution Approach 2:
The sleeve employs flexible material construction that allows it to bend, compress, and conform to the installation space requirements. This flexibility enables the tool to enter constrained areas between door knobs while maintaining its alignment function, solving both the precision and adaptability requirements simultaneously.
