Solution Overview

Problem

Conventional wire hook displays are vulnerable to theft as items can be easily removed without drawing attention, and there is a need for inventory monitoring, especially in retail environments.

Innovation Solution

An anti-sweeping hook system with a helical coil and rotating handle that loads and unloads items, featuring a rotor and stator configuration to detect rotations and transmit inventory data wirelessly, including an MCU to trigger alarms and monitor item removals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional wire hook displays are used, then ease of operation is improved, but security against theft deteriorates

Engineering Contradiction:
Improveease of operationVSAvoidtheft vulnerability
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary anti-action by incorporating a sensor system that detects removal attempts before actual theft occurs. The sensor monitors the wire hook for unauthorized removal actions and triggers an alarm or notification, preventing the theft from completing successfully. This proactive detection mechanism addresses the security vulnerability while maintaining the ease of legitimate operation.

Inventive Principle:
Principle #9Preliminary anti-action

2Measurement precision

If manual inventory monitoring is implemented, then measurement precision is improved, but productivity deteriorates

Engineering Contradiction:
Improveinventory monitoring accuracyVSAvoidoperational efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent implements self-service by using automatic sensors that continuously monitor inventory levels on wire hooks without requiring manual intervention. The sensor system automatically detects when items are removed or added, tracks inventory levels, and communicates this information to a central system or displays it locally. This eliminates the need for manual counting while maintaining precise inventory measurement, thereby improving both accuracy and operational efficiency.

Inventive Principle:
Principle #25Self-service

3Loss of information

If remote inventory monitoring is implemented, then information availability is improved, but device complexity increases

Engineering Contradiction:
Improveinventory information availabilityVSAvoidsystem complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a multi-functional sensor system that combines inventory monitoring, data transmission, and alerting capabilities in a single integrated device. The sensor not only detects inventory changes but also wirelessly transmits this information to remote systems and can trigger local or remote alarms. This consolidation of multiple functions into one system reduces overall complexity compared to having separate systems for each function while maintaining comprehensive information availability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Anti-sweeping hook with a display hook, a helical coil, and rotating handle. The display hook may be straight with a first end and second end opposite the first end. The helical coil is disposed about the display hook and extends lengthwise along the display hook. The helical coil has a first coil end proximate the first end of the display hook. Rotation of the helical coil in a first direction loads the retail merchandise onto the display hook. Rotation of the coil in a second direction opposite the first direction removes the retail merchandise. The rotating handle is configured to determine a number of retail items stored on the display hook, based on the number and direction of rotation of the rotating handle. The rotating handle includes an MCU and wireless communications module to process and wirelessly transmit inventory data indicating the number of retail items on the display hook.
