Security system for portable consumer article
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security systems for displaying portable consumer articles, such as purses, require inconvenient removal procedures and leave displayed items unprotected during access, making them vulnerable to theft.
Innovation Solution
A security system with cantilevered arms and a blocking assembly that allows for flexible display and secure positioning of articles, enabling easy access while maintaining security by changing the blocking assembly's state to prevent separation of articles from the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a blocking assembly is added to prevent article removal, then security is improved, but device complexity increases
Solution Approach 1:
The blocking assembly is segmented into modular components including blocking members, link members, and pivot points that can independently move and coordinate. This segmentation allows the system to achieve complex security functionality through simple, discrete parts rather than a monolithic complex mechanism.
Solution Approach 2:
The blocking assembly transitions between static blocking positions and dynamic moving positions. The link members and pivot points enable the blocking members to move from a secured position (blocking article removal) to a loading position (allowing article placement), providing dynamic security control without permanent complex structures.
2Productivity
If multiple articles are displayed on a single security system, then productivity is improved, but ease of operation deteriorates due to last-in-first-out removal limitation
Solution Approach 1:
The blocking assembly is divided into multiple independent blocking members (first blocking member, second blocking member, etc.), each capable of independently blocking or unblocking articles at different positions on the display. This allows selective access to any article regardless of placement order, eliminating the last-in-first-out limitation.
Solution Approach 2:
The blocking assembly provides more blocking capacity than the minimum required by having multiple blocking members that can operate independently. This excessive blocking capability enables selective unblocking of individual articles while maintaining security on remaining articles, improving operational flexibility.
3Ease of operation
If articles are removed for inspection, then ease of operation is improved, but reliability deteriorates as removed articles remain unprotected
Solution Approach 1:
The blocking assembly dynamically adjusts its blocking state in response to article removal. When an article is removed from the display, the blocking members automatically transition to block the empty position, maintaining continuous security coverage. This dynamic response ensures that security is maintained during normal operational activities.
Solution Approach 2:
The system provides automatic feedback through the blocking assembly's mechanical design. When an article position becomes vacant, the blocking mechanism detects this change and automatically moves to block the opening, providing real-time security adjustment without human intervention.

AI summary
A security system having: a frame with first and second support assemblies respectively having first and second cantilevered arms, each with a free end; and a blocking assembly. The first free end can be directed into a U-shaped portion on a first portable consumer article to allow the U-shaped portion to straddle the first cantilevered arm. The second free end can be directed into a U-shaped portion on a second portable consumer article to allow the U-shaped portion on the second article to straddle the second cantilevered arm. Changing the blocking assembly from the loading state into the securing state prevents the first and second articles, straddling respective arms, from being separated from the security system. Changing the blocking assembly from the securing state into the loading state allows either of the first and second displayed articles to be separated from the security system without separating the other.
