Solution Overview

Problem

Existing transport hangers with straight hook ends tend to get caught on rail edges during transfer, leading to damage or soiling of items and potential entanglement with other hangers, as they either slip off or form a cross configuration, making them difficult to separate.

Innovation Solution

The hook ends of the transport hangers are designed with a partially beveled end face, allowing them to slide smoothly onto and off rails, preventing entanglement and ensuring reliable transfer, while the rail is also adapted with an inclined surface to match the bevel, ensuring a flat contact and preventing sharp edge interactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the hook end has a flat end face running at right angles to the central axis, then the manufacturing is simple, but the hanger hook gets caught on the rail and cannot slide properly

Engineering Contradiction:
Improvemanufacturing simplicity of hook endVSAvoidreliable transfer of hanger hook to rail
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The end face of the hook end is given a partial bevel instead of being completely flat or completely conical. This local modification creates a specific zone with improved sliding properties while maintaining simplicity in other areas, resolving the contradiction between manufacturing ease and reliable rail transfer.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The geometry of the hook end is modified by introducing a beveled portion that changes the angle parameters of the end face. This parameter change enables the hook end to slide smoothly onto the rail while maintaining structural integrity and manufacturing feasibility.

Inventive Principle:
Principle #35Parameter changes

2Device complexity

If the hook end has a flat end face, then the structure is simple, but the hanger hooks form a cross configuration and get entangled with preceding hangers

Engineering Contradiction:
Improvestructural simplicity of hanger hookVSAvoidseparation of hanger hooks at end of rail
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

A beveled portion is introduced locally at the end face of the hook end, while the rest of the hook structure remains simple and unchanged. This localized modification prevents cross-forming and entanglement without complicating the overall device structure.

Inventive Principle:
Principle #3Local quality

3Device complexity

If the hook end gets caught on the rail, then no additional mechanism is needed, but the items of clothing hanging on the hanger are damaged or soiled

Engineering Contradiction:
Improvesimplicity of hanger designVSAvoiddamage and soiling of items of clothing
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The geometry of the hook end is modified by introducing a beveled portion that changes the angle parameters of the end face. This parameter change enables the hook end to slide smoothly onto the rail while maintaining structural integrity and manufacturing feasibility.

Principle #35Parameter changes

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This design ensures that transport hangers consistently hang correctly on rails, preventing damage and soiling, and avoids entanglement, allowing for smooth and reliable transfer of both loaded and empty hangers, enhancing operational efficiency in laundry and clothing manufacturing processes.

Implementation Method 1

the hook end slides off a rail used for further transport of the transport hanger under all circumstances, which ensures that the curved hanger hook always hangs on the rail
