Security Tag Detacher With Interlock Feedback Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing EAS security tag removal systems face high failure rates due to user error, particularly when using automated devices, as users lack sufficient feedback to correctly time the detachment process, leading to incomplete or damaged tag removals.
Innovation Solution
A detaching device with a handle and interlock mechanism that allows users to control the rotation and retraction of a hook to release the security tag, providing clear feedback and ensuring proper alignment and timing for secure detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated detaching devices are used, then productivity increases, but user feedback is insufficient leading to high failure rates due to user error
Solution Approach 1:
The device incorporates an interlock mechanism that provides immediate tactile and visual feedback to the user during the detachment process. The interlock member must be in a specific position for the handle to pivot, and the hook must be properly received by the tag housing receiving portion to allow handle movement. This feedback system guides the user through the correct sequence of actions, eliminating guesswork and reducing user error while maintaining automated efficiency.
2Reliability
If manual control mechanisms are added to provide feedback, then reliability improves, but device complexity increases
Solution Approach 1:
The interlock mechanism combines multiple functions into a single integrated component structure. The interlock member simultaneously controls hook movement, provides user feedback, and ensures proper alignment between the hook and tag housing receiving portion. The handle pivot mechanism integrates the detachment action with the interlock state verification, eliminating the need for separate control systems while maintaining high reliability through mechanical feedback.

AI summary
A detaching device for releasing a tack body from a tag housing is disclosed. the detaching device includes a housing, a handle pivotally mounted to the housing and configured to pivot about a handle axis. The device further includes a detacher translation mechanism configured to move a detacher portion from a first non-release position to a second release position, wherein the detacher translation mechanism converts rotational movement of the handle about the handle axis to rotational movement of the detacher portion about a first axis, wherein when the detacher portion moves to the second release position, the detacher portion is configured to be received by a receiving portion of the tag housing thus releasing the tack body from the tag housing.
