Flexible Screw Alignment Sleeve for Door Knob Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The alignment of screws through apertures in a base plate with threaded apertures in mounting sleeves for door knobs 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, made from materials like elastomers or cross-linked polymers, which compresses to secure the door knobs together, enhancing visibility and ease of installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional door knob installation method is used without alignment aid, then the installation process requires precise manual alignment of screws with threaded apertures, but this leads to limited visibility and increased installation time and frustration
Solution Approach 1:
The patent introduces an alignment sleeve as an intermediary tool that fits over the mounting sleeve and provides visual alignment indicators. This mediator component bridges the gap between the screw and threaded aperture, making alignment visible and precise without requiring complex tools or procedures
Solution Approach 2:
The alignment sleeve incorporates visual indicators (such as colored rings or markings) that change or become visible when proper alignment is achieved. These color or visual changes provide immediate feedback to the installer, eliminating the need for precise manual measurement and reducing installation time
2Ease of operation
If traditional door knob installation method is used without alignment aid, then the installation process is straightforward in concept, but the limited visibility of screw locations relative to apertures creates frustration and inefficiency
Solution Approach 1:
The alignment sleeve acts as an intermediary that provides visual information about screw positions relative to threaded apertures. It includes features like alignment indicators or visible markers that convey spatial relationship information that would otherwise be difficult to see during installation
Solution Approach 2:
The alignment sleeve adds a visual dimension to the alignment process by incorporating colored rings, markings, or transparent sections that provide spatial information in a different visual plane, making it easier to perceive the relationship between screws and apertures
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The flexible sleeve simplifies the alignment process by providing a clear path for screw alignment, reducing installation time and frustration, especially in construction environments where visibility is limited.
