Expandable Clothes Hanger With Tensioning Lower Garment Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clothes hangers fail to adequately support the lower portion of draped clothing, leading to creasing, wrinkling, and distortion, especially during transport and storage.
Innovation Solution
An expandable clothes hanger design featuring downward extending elements that can be moved from a retracted to an expanded position to pull the lower portion of the clothing taut, providing support to both the upper and lower sections of the garment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional hangers support only the top portion of clothing, then the hanger structure remains simple, but the lower portion of clothing becomes creased and wrinkled
Solution Approach 1:
The hanger is divided into multiple functional segments: an upper support bar for hanging, and expandable lower support elements that can be deployed to support the lower portion of clothing. This segmentation allows the hanger to provide comprehensive support while maintaining a simple folded state for storage.
Solution Approach 2:
The lower support elements are designed to be dynamic rather than static - they can be expanded from a retracted position to an extended position to provide support when needed, and collapsed when not in use. This dynamic capability allows the hanger to adapt its complexity based on operational requirements.
2Reliability
If the hanger structure is expanded to support the lower portion of clothing, then creasing is reduced, but the hanger occupies more storage space
Solution Approach 1:
The lower support elements are designed to nest within or alongside the upper support structure when in the retracted position. This nesting arrangement minimizes the overall volume of the hanger during storage while allowing full expansion when clothing support is required.
Solution Approach 2:
The collapsible nature of the lower support elements allows the hanger to transition between a compact storage configuration and an expanded operational configuration, effectively reducing the volume occupied during storage while maintaining protective capabilities when needed.
3Reliability
If downward extending elements are added to support the lower portion of clothing, then fabric distortion is prevented, but the manufacturing complexity increases
Solution Approach 1:
The hanger is constructed from separate modular components - the upper support bar and the lower support elements can be manufactured independently and then assembled. This segmentation simplifies the manufacturing process for each individual component while achieving the complex overall function of comprehensive clothing support.
Solution Approach 2:
The lower support elements utilize simple mechanical linkages or spring mechanisms that can be manufactured using standard fabrication processes, making the added complexity manageable while providing the necessary fabric protection functionality.

AI summary
An expandable clothes hanger to hang, display, store, or transport an article of clothing with minimal creasing. The expandable clothes hanger has a hook extending upward from a bar element that supports an upper portion of an article of clothing draped thereon. Downward extending elements extend downward from the bar element and cross each other at at least a single point. Raising the crossing point along the downward extending elements causes the lower portion of the downward extending elements to extend outward, pulling taut the lower portion of draped article of clothing. Lowering the crossing point along the downward extending elements causes the lower portion of the downward extending elements to be pulled together, allowing for more compact storage of the expandable clothes hanger or for easier placement or removal of draped articles of clothing. The downward extending elements can also be configured as an attachment to a conventional hanger.
