Foldable Garment Hanger With Size-Marker Hinge Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ship-on hangers that fold for space efficiency in shipping often have loose or weak hinges due to live hinges, which are prone to weakening with use, and do not allow for secure locking in transportation or display conditions.
Innovation Solution
A garment hanger design featuring a connecting portion with a live hinge that can fold and lock using a size marker, allowing the hanger to transition between transportation and display conditions without hinge movement, ensuring stability and reducing material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a live hinge is used to allow the suspension portion to fold towards the garment support portion, then the hanger can be compacted for space-efficient shipping, but the hinge becomes loose or slack and weakens with use
Solution Approach 1:
The size marker is pre-positioned to engage with the hinge mechanism, establishing a predetermined locked state that prevents the hinge from becoming loose or slack during use. This preliminary engagement ensures the hinge maintains its structural integrity while still allowing folding for compact shipping.
2Adaptability or versatility
If the hinge is made flexible using thin material to enable folding, then the hanger can be compacted for shipping, but the hinge becomes weaker and more prone to failure
Solution Approach 1:
The hinge is pre-configured with engagement features that lock into the size marker, establishing a predetermined locked state before use. This preliminary action ensures that the flexible, thin-material hinge maintains its strength during actual use while still enabling folding for compact shipping.
3Ease of operation
If the size marker is made movable to allow transition between transportation and display conditions, then the hanger can be easily converted between modes, but the locking mechanism becomes more complex
Solution Approach 1:
The size marker serves multiple functions: it acts as both a size indicator and a locking mechanism component. By integrating these functions into a single component, the design achieves easy mode conversion without significantly increasing overall mechanism complexity.
Solution Approach 2:
The size marker's movement itself creates the locking and unlocking actions. When the size marker is repositioned, it automatically engages or disengages from the hinge, providing self-service locking without requiring additional complex mechanisms or separate locking components.

AI summary
A foldable garment hanger is disclosed which includes a hook which can be folded relative to the garment supporting portion by virtue of a hinge. A size marker is attached to a connecting portion which joins the hook to the garment support portion and includes the hinge. When the size marker straddles the hinge the connecting portion is held rigid thereby fixing the hook relative to the garment support portion. Preferably the size marker is slidable to expose the hinge thereby allowing the hanger to be easily moved between an erect display condition and a folded transportation condition.
