Solution Overview

Problem

Conventional hanging devices lack sufficient degrees of freedom in movement and rotation, leading to collisions and instability when hanging objects at edges or corners, and are prone to shaking during extended use.

Innovation Solution

The hanging device features a transportation assembly with perpendicular horizontal axes for three-dimensional movement, a rotating assembly for vertical axis rotation, and a pulley system for vertical movement, enhancing the hook's freedom of movement and stability by allowing it to move in two vertical sections and rotate freely around a vertical axis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the hanging device has a long hanging path, then the operational range is extended, but the hook tends to shake and collide with the object

Engineering Contradiction:
Improveoperational rangeVSAvoidhook stability
Core Design Contradiction:
Area of stationary objectVSStability of the object's composition

Solution Approach 1:

The hanging path is divided into two separate vertical paths (first vertical path in accommodation main body, second vertical path in sliding assembly). This segmentation allows the hook to move through a longer total path while maintaining stability by distributing the movement across structured guides

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention adds horizontal movement capability through the transportation assembly (movable connected to accommodation main body, capable of moving along horizontal direction). This transforms the system from single-dimensional vertical movement to multi-dimensional movement, extending operational range without compromising vertical stability

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

2Adaptability or versatility

If the hook is extended for too long to reach edge or corner objects, then the operational versatility is improved, but the hook becomes unstable and prone to shaking

Engineering Contradiction:
Improveability to hang edge or corner objectsVSAvoidhook stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The invention introduces a rotatable assembly that enables the hook to rotate around a vertical axis. This dynamic capability allows the hook to adapt its orientation to reach edge or corner objects while maintaining stability through controlled rotation rather than uncontrolled swinging

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

By adding rotational movement around a vertical axis to the existing vertical and horizontal movements, the system gains three-dimensional positioning capability. This allows the hook to reach difficult-to-access locations while maintaining stability through precise positional control

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

3Object-affected harmful factors

If operators keep a considerable distance from the hanging device, then safety is improved, but the operators cannot accurately judge the positional relation between the hanging device and the object

Engineering Contradiction:
Improveoperator safetyVSAvoidpositional judgment accuracy
Core Design Contradiction:
Object-affected harmful factorsVSMeasurement precision

Solution Approach 1:

The hanging device incorporates a transportation assembly with movable connection to the accommodation main body, enabling the entire assembly to move horizontally along with the hook. This self-following capability allows the device to maintain its position relative to the object being hung, providing visual feedback to operators while maintaining safe distances

Inventive Principle:
Principle #25Self-service

AI summary

A hanging device (100) includes an accommodation main body (110), a sliding assembly (120), a hook (130), and the accommodation main body that includes two parallel sidewalls (111), in which a first vertical path is defined between the two sidewalls. The sliding assembly is movably connected between the two sidewalls to move relative to the main body along the first vertical path. The sliding assembly further includes a sliding rail (121) which defines a second vertical path, and the hook (130) is movably connected to the sliding rail to move relative to the sliding assembly along the second vertical path.
