Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems for optical wear and similar articles face challenges in allowing customers to handle and try on items without interference, while also being easily attachable and detachable by authorized personnel, and in preventing unauthorized removal.
Innovation Solution
A security tag system with a rotational clip and housing base that applies a clamping force using cap and latch springs, allowing secure attachment and detachment with a one-click method, and featuring a sensor for EAS system integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables or chains are used to connect eyeglass frames to weights or fixtures, then security against theft is improved, but the cables or chains can break or become tangled from customer handling, reducing reliability and ease of operation
Solution Approach 1:
The patent replaces traditional mechanical cable or chain security systems with a magnetic field-based security tag system. The security tag uses magnetic attraction between a magnet in the tag and a ferromagnetic material in the display fixture, eliminating physical cables or chains that can break or tangle. This substitution maintains security effectiveness while greatly improving ease of customer handling.
Solution Approach 2:
The patent changes the security mechanism from mechanical connection (cables/chains) to magnetic field interaction. By adjusting magnetic field strength and using appropriate ferromagnetic materials, the system achieves secure attachment that is easily detachable by authorized personnel using a magnetic detacher, while remaining comfortable for customer handling.
2Reliability
If cables or chains are attached to eyewear, then security is improved, but the customer's ability to try on the eyewear comfortably is interfered with, reducing ease of operation
Solution Approach 1:
The patent replaces mechanical cable or chain attachments with a magnetic field-based security system. The security tag attaches to the eyewear frame without physical cables or chains, allowing customers to handle and try on the eyewear comfortably while maintaining theft prevention through magnetic attraction to the display fixture.
3Ease of operation
If personnel remove cables or chains to allow customers to try on products, then ease of operation is improved, but the effectiveness of the security system is reduced
Solution Approach 1:
The patent replaces mechanical cable or chain systems with a magnetic field-based security tag system that requires no manual intervention. Customers can freely handle and try on eyewear as the magnetic security tag remains attached to the display fixture, maintaining security effectiveness without reducing customer access.
Solution Approach 2:
The security system operates autonomously without requiring personnel intervention. The magnetic security tag automatically secures the eyewear to the display fixture and can be easily detached by authorized personnel using a magnetic detacher, eliminating the need for manual cable or chain management.
4Reliability
If eyeglasses are displayed in locked glass cases, then security against theft is improved, but the overhead costs and requirement for salespeople increase, reducing productivity
Solution Approach 1:
The patent replaces physical locked glass display cases with a magnetic field-based security tag system. This allows eyewear to be displayed openly without locks or barriers, eliminating the need for additional security infrastructure and reducing dependency on salespeople for security monitoring, thereby improving operational efficiency.
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
Enables secure attachment and easy handling of articles without damage, allowing customers to try on items comfortably while preventing unauthorized removal, with magnetic detachment for authorized personnel.
Implementation Method 1
a cap spring (614) disposed in the housing base (404) such that a center axis (818) thereof is perpendicular to a center axis (816) of the latch spring (612)... a pushing force applied by the latch spring (612) to the latch (610) causes the engagement structure (622) to travel into the aperture (628)
Implementation Method 2
The latch (610) may disengage the rotational clip (406) when a magnetic field is applied thereto

AI summary
Systems (100) and methods (1000) for operating a Security Tag ("ST"). The methods involve rotating a Rotational Clip ("RC") of ST (132) towards a Housing Base ("HB") of ST until RC (406) contacts a latch (610) disposed within HB (404), where an article resides between a first pad (602) fixedly coupled to RC and a second pad (604) movably coupled to HB. An angled surface (626) of RC slides against an angled surface (624) of the latch so as to cause compression of a cap spring (614) and a latch spring (612). The cap spring is disposed in HB such that a center axis (818) thereof is perpendicular to a center axis (816) of the latch spring. When the latch becomes aligned with an aperture (628) formed in the rotational clip, the latch travels into the aperture as result from a pushing force applied thereto by the latch spring.
