Solution Overview

Problem

Conventional hanging devices often require the use of both hands to hang and unhang objects, and the further the hook is closed, the more difficult it is to thread objects into or out of the eyelet, while also providing inadequate security against slipping.

Innovation Solution

A hanging device with a wall bracket and a hook featuring a connecting section that slopes obliquely downwards to a free section parallel to the wall mounting surface, forming a curved projection of at least 180°, creating a gap to secure objects and facilitate easy hanging by allowing objects to slide onto the hook from above.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the hook is made more closed to prevent objects from sliding off, then security against slipping is improved, but it becomes more difficult to thread objects into or out of the eyelet

Engineering Contradiction:
Improvesecurity against slippingVSAvoidease of threading objects
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The hook is divided into two functional sections: a connecting section that integrates with the wall bracket and provides structural support, and a free section that forms the hanging loop. This segmentation allows the free section to be optimally shaped for preventing slips while remaining easily accessible for threading operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The free section of the hook is positioned in a plane parallel to and spaced apart from the wall mounting surface, creating a gap between the hook and wall. This spatial arrangement in three dimensions allows the hook to maintain a closed shape for security while providing adequate clearance for easy threading of objects.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If the hook is made more open to ease threading of objects, then ease of operation is improved, but security against slipping is reduced

Engineering Contradiction:
Improveease of threading objectsVSAvoidsecurity against slipping
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

Different sections of the hook have different geometric properties optimized for their specific functions. The connecting section has a sloping top surface for guiding objects, while the free section forms a closed loop with specific curvature to prevent slipping. This local optimization of geometry ensures both ease of threading and security against slips.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If both hands are used to hang and unhang objects, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveease of hanging and unloadingVSAvoidoperational complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The sloping top surface of the connecting section automatically guides the eyelet of suspended objects onto the hook during the hanging process. This self-guiding feature reduces the manual dexterity required and allows users to hang objects more easily without requiring both hands for precise positioning.

Inventive Principle:
Principle #25Self-service

AI summary

The invention relates to a suspension device (10) for the suspension of items which comprise, in particular, a loop or eyelet, having a wall mount (11) which provides a wall-mounting surface (12), and having a hook (14), wherein the hook (14) has a connecting portion (16) which is connected to the wall mount (12), and a free portion (18) which adjoins the connecting portion, wherein the connecting portion (16) has an upper side (26) which slopes downwards from the wall mount (11) to the free portion (18), wherein the free portion (18) extends at a distance from the wall mount (11) and substantially parallel to the wall-mounting surface (12) in such a way as to be designed to inhibit suspended articles from sliding off, and wherein the hook (14) is shaped in such a way that it forms, as seen in perpendicular projection onto the wall-mounting surface (12), a curve which turns through an angle of at least 180°, preferably at least 240° and particularly preferably at least 270°.
