EAS Tag Attaching Panel with Adhesive and Plug Mechanisms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic article surveillance (EAS) devices face challenges in attaching to consumer goods like shoes and portable electronics, which lack convenient features for easy attachment, and require a compact and effective solution to prevent theft while allowing customers to handle and try products.
Innovation Solution
The EAS device employs an adhesive element combined with a plug compatible with charging ports for portable electronics and attaches to the sole of shoes, using passive and active electronic elements like acousto-magnetic and RFID tags, along with a microprocessor and motion sensors to ensure secure attachment and alarm generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional EAS devices are used on consumer goods like shoes and portable electronics, then theft prevention is achieved, but attachment difficulty increases and customer handling ability decreases
Solution Approach 1:
The EAS device is divided into separate functional components: a reusable housing containing the electronic surveillance elements and a disposable or reusable attaching panel with adhesive elements. This segmentation allows the attaching panel to be optimized for ease of attachment to specific products while the housing contains the core EAS functionality.
Solution Approach 2:
An attaching panel serves as an intermediary element between the EAS device housing and the consumer product. This panel includes adhesive elements that facilitate easy attachment to surfaces like shoe uppers or portable electronics, eliminating the need to modify the product itself or the housing directly.
2Volume of moving object
If EAS devices are made compact for storage, then space efficiency improves, but attachment reliability may deteriorate
Solution Approach 1:
By separating the EAS housing from the attaching panel, the housing can be minimized in size for compact storage while the attaching panel provides the necessary surface area for reliable adhesive attachment. The panel can be folded or rolled when not in use, maintaining compactness while ensuring attachment reliability when deployed.
3Ease of operation
If adhesive elements are used for attachment, then ease of attachment improves, but attachment strength may be insufficient for high-value items
Solution Approach 1:
The attaching panel combines multiple attachment mechanisms: adhesive elements for easy initial attachment and additional mechanical features like tabs, slots, or interlocking elements that engage with corresponding features on the product or display fixture. This combination provides both ease of attachment and sufficient holding strength.
Solution Approach 2:
The attaching panel may use composite construction with different materials optimized for different functions: adhesive layers for bonding, rigid support structures for strength, and flexible elements for conforming to product surfaces. This composite approach ensures both ease of application and strong attachment.

AI summary
An electronic article surveillance (EAS) device has a housing containing EAS electronics and a panel extending from the housing. An adhesive element on the panel provides a means of attaching the EAS device to an object to be monitored. The EAS device has a switch to detect when the EAS device is mounted to an object. The electronics within the housing monitor the switch. The switch may be associated with, or mounted in, the panel. The panel may be hinged to the housing. The panel may fold flat to the housing when not in use, and the switch will disconnect any power source to conserve energy when the panel is closed. The EAS electronics can communicate with external devices and an external EAS system which may include cloud functionality.
