Solution Overview

Problem

Conventional slatwall and pegboard display systems are prone to hanger dislodgment, leading to accidental item falls and easy theft of merchandise, particularly for small, high-value items.

Innovation Solution

Self-locking hanger devices with removable coupling and locking mechanisms that secure to slatwall, pegboard, or slatgrid structures without requiring special tools, featuring interlocking hanger members and optional locking devices to prevent removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional hangers are used on slatwall or pegboard, then items can be displayed easily, but the hangers can be dislodged by accidental bumps or easy removal by shoplifters

Engineering Contradiction:
Improveease of displayVSAvoidsecurity against dislodgment
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The hanger is divided into multiple members (first hanger member, second hanger member, third hanger member) that can be independently positioned and secured. Each member can be independently engaged with the slatwall structure, allowing the hanger to be segmented into display-facing and structure-facing portions, thereby achieving both ease of display and security against dislodgment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hanger members are nested together to form a unified structure. The first, second, and third hanger members are positioned and secured in sequence, with each member nested within or alongside the others, creating a layered configuration that provides both accessibility for customers and security against removal.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If hangers are securely locked to prevent theft, then security is improved, but special tools are required for installation and removal

Engineering Contradiction:
Improvesecurity against theftVSAvoidease of installation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The hanger system is designed to be self-securing through the interaction of its multiple members with the slatwall structure. The first hanger member engages with upper slots, the second member engages with lower slots, and the third member provides additional support, creating a self-locking configuration that does not require external tools for installation or removal.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Instead of using a traditional lock mechanism that requires tools, the invention inverts the approach by using the hanger members themselves to create friction and mechanical interference with the slatwall slots. The members are inserted into slots in a manner that creates natural resistance to removal without requiring additional locking components or tools.

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

Devices, systems and methods for hanging and securing items for display. The hanger devices and systems are self-locking, secure and do not require special tools to install and/or remove. A hanger for displaying at least one item of merchandise relative to a structure includes a first hanger member and a second hanger member that are removably coupled to each other, the first hanger member and second hanger member forming a retaining portion that retains the hanger to a structure and a hanging portion that enable items of merchandise to be placed thereon and be displayed. Additionally, a hanger capture device is provided to be mounted to a slatwall to prevent hangers from being removed from the slatwall.
