Solution Overview

Problem

Existing furniture hangers with anti-tipping protection mechanisms, such as flexible elements or bolted dowels, face issues with accidental upward displacement leading to failure and difficulty in unhooking, as well as requiring tools for installation.

Innovation Solution

A furniture hanger with a hanging hook featuring a descending tooth and a sliding safety body with an ascending tooth, utilizing a fixed guiding recess with a toothed surface for locking, allowing for secure attachment and easy unhooking without tools, facilitated by a handling hole for finger operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If bolted dowels of complementary shape are used for anti-tipping fixation, then anti-tipping protection is provided, but the furniture becomes hard to unhook when necessary

Engineering Contradiction:
Improveanti-tipping protectionVSAvoidunhooking ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The safety element is made movable along the hook body rather than fixed. The element can slide vertically to engage or disengage from the ascending tooth position, allowing easy unhooking by simply moving the element down while maintaining secure anti-tipping protection during normal use.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The safety mechanism is segmented into a movable safety element and a fixed hook body with guiding recess. This segmentation allows independent movement of the safety element to enable easy unhooking while the fixed hook body maintains the anti-tipping function through its toothed geometry.

Inventive Principle:
Principle #1Segmentation

2Reliability

If conventional fixing structures are used, then secure attachment is achieved, but installation requires screwdrivers and tools making it more difficult

Engineering Contradiction:
Improveattachment securityVSAvoidinstallation ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The safety element with integrated handling hole enables self-service installation and unhooking without tools. The user can directly manipulate the safety element through the handling hole to engage or disengage it, eliminating the need for screwdrivers or other installation tools while maintaining secure attachment.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The handling hole acts as an intermediary that facilitates direct finger operation of the safety element. This intermediary allows users to easily grasp and move the safety element for installation and unhooking without requiring tools, while the safety element itself provides the secure attachment function.

Inventive Principle:
Principle #24Intermediary (Mediator)
