Magnetic Alignment Mechanism for Retractor Tethering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional retractors fail to securely align personal articles, such as cell phones, with the retractor housing when the tethering line is retracted, leading to discomfort and potential damage due to misalignment and dangling of the article.
Innovation Solution
A connector and retractor system utilizing magnets to align personal articles with the retractor housing, ensuring proper alignment and orientation, with the magnets arranged on both the retractor and personal article parts to encourage alignment and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional retractors are used without alignment mechanisms, then the device structure remains simple, but the personal article becomes misaligned and dangling when retracted, causing discomfort and potential damage
Solution Approach 1:
The patent replaces complex mechanical alignment mechanisms with a magnetic field-based alignment system. Magnets embedded in the connector housing create magnetic attraction forces that automatically orient and align the personal article (containing magnetic elements) with the retractor body, eliminating the need for mechanical guides, slots, or complex joint structures while achieving stable alignment.
Solution Approach 2:
The patent introduces magnetic fields as an intermediary force between the connector housing and the personal article. The magnets in the housing and corresponding magnetic elements in the article create an invisible magnetic field that mediates the alignment process, allowing the article to be automatically positioned correctly without direct mechanical contact or complex structural interfaces.
2Manufacturing precision
If magnets are added to the connector system for alignment, then alignment precision is improved, but the device complexity increases due to additional magnetic components
Solution Approach 1:
The patent designs the connector housing to serve multiple functions: it provides structural attachment, houses the magnetic alignment elements, and acts as the mounting interface for the personal article. The magnets are integrated into the housing structure itself rather than being separate components, allowing the housing to simultaneously provide mechanical support and magnetic alignment functionality, thereby reducing overall device complexity.
Solution Approach 2:
The patent combines the magnetic alignment elements with the connector housing structure. The magnets are embedded directly into the housing, merging the alignment function with the structural function of the housing. This integration eliminates the need for separate alignment mechanisms and reduces the number of discrete components while maintaining precise alignment capability.
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 magnetic alignment system ensures the personal article is securely and comfortably positioned with the retractor, reducing wear and tear on both the article and user's clothing, while allowing convenient access and use of the article without the need for constant adjustment.
Implementation Method 1
The connector can include magnets to encourage alignment of the personal article with the retractor when the tethering line is retracted and the personal article is adjacent the retractor.
Data Source
AI summary
Connector and retractor systems are disclosed with some embodiments comprising a retractor housing and a line within the retractor housing. The housing also has a hole from which the line extends, and a spring within the retractor housing which urges retraction of the line. A personal article can be attached to the line. A connector is included between the retractor housing and the personal article, with the connector having magnets to cause alignment of the personal article with the retractor housing when the personal article is retracted to the housing.
