Plastic Hook with Integrated Sizer for Paper Hanger Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paper hangers face challenges in providing a strong and aesthetically pleasing hook that can securely support garments, while also accommodating a sizer for displaying garment indicia, particularly a crown sizer.
Innovation Solution
A plastic hook design that includes a hook body with a hanging arm and an attachment base, featuring a collar and flange for secure attachment to a paper hanger body, along with a lock member that includes a sizer body portion and a tongue for locking the hook in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a cardboard hook is stamped from the same paper stock as the hanger body, then material consistency and aesthetics are improved, but the hook strength is insufficient to support garment weight
Solution Approach 1:
The patent combines paper stock material for the hanger body with a plastic hook material that has superior strength properties. This composite construction allows the hook to support garment weight while maintaining aesthetic consistency through proper material selection and finishing.
Solution Approach 2:
The hanger is divided into separate components: a paper stock body and a plastic hook. This segmentation allows each component to be optimized for its specific function—the paper body for aesthetics and the plastic hook for strength—while still forming a unified product.
2Strength
If a plastic hook is attached to a paper hanger body using a rivet or complex attachment structure, then hook strength is improved, but manufacturing complexity and assembly difficulty increase
Solution Approach 1:
The collar and lock member are integrated into a single piece that combines both the attachment function (collar fitting through the attachment opening) and the locking function (lock member engaging the collar). This merging eliminates the need for separate rivets or complex multi-part attachment structures.
Solution Approach 2:
The lock member is designed to be inserted through the hanging arm and automatically engage with the collar through simple insertion motion. The system self-secures without requiring additional tools, complex alignment procedures, or multiple assembly steps.
3Device complexity
If a simple attachment structure is used to attach the plastic hook to the paper hanger body, then manufacturing complexity is reduced, but attachment strength and reliability decrease
Solution Approach 1:
The collar is inserted through the attachment opening in the paper hanger body, and the lock member is nested within the collar structure. The lock member's tongue engages with the collar from the inside, creating a nested configuration that provides strong mechanical interlocking with minimal external complexity.
Solution Approach 2:
The collar is designed with a curved, collar-like shape that fits through the attachment opening and provides a continuous engagement surface for the lock member. This curved geometry distributes stresses evenly and creates a reliable mechanical connection.
4Device complexity
If the hook design does not include a sizer, then manufacturing simplicity is maintained, but the ability to display garment indicia and use a crown sizer is lost
Solution Approach 1:
The lock member serves multiple functions: it secures the plastic hook to the paper hanger body through the collar engagement, and simultaneously provides a sizer body portion that can display garment indicia and accommodate a crown sizer. This multi-functionality adds versatility without significantly increasing overall structural complexity.
