Crown-Type Hanger Sizer With Offset Boss Locking for Angled Hooks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crown-type sizers for hangers are easily detachable, leading to risks of product exchange and ingestion, especially when applied to plastic hangers with hooks at angles other than 90 degrees, and previous solutions compromised hanger integrity or were not aesthetically pleasing.
Innovation Solution
A crown-type sizer with a peripheral wall structure featuring trapezium-shaped longitudinal and rectangle-shaped transverse sides, including protrusion bosses that engage with a hanger's groove and protrusion, providing secure snap-in locking and stability, suitable for plastic hangers with hooks at angles other than 90 degrees.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the crown-type sizer is made easily detachable from the hanger, then the ease of operation is improved, but the reliability deteriorates due to risks of product exchange and ingestion
Solution Approach 1:
The sizer is designed with a dynamic attachment mechanism that allows easy installation but resists removal. The protrusion boss engages with the groove and protrusion on the hanger hook, creating a one-way locking mechanism that is simple to attach but secure against detachment
Solution Approach 2:
The protrusion boss acts as an intermediary element between the sizer and the hanger hook. It mediates the connection by engaging with the groove and protrusion features on the hanger, providing secure attachment while maintaining ease of installation
2Reliability
If the crown-type sizer is assembled in an integral manner to prevent removal, then the reliability is improved, but the device complexity increases and hanger integrity is compromised
Solution Approach 1:
The sizer is segmented into a peripheral wall structure with distinct protrusion bosses that can engage with corresponding features on the hanger. This segmentation allows the sizer to be attached securely without requiring integral assembly, maintaining both reliability and simplicity
Solution Approach 2:
The protrusion boss is nested within the peripheral wall structure of the sizer, and this entire assembly nests onto the hanger hook. The nested configuration allows secure attachment through the engagement of the protrusion boss with the groove and protrusion on the hanger
3Adaptability or versatility
If the crown-type sizer is designed for plastic hangers with angled hooks, then the adaptability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The protrusion boss is designed with a universal engagement mechanism that can accommodate various hook angles. The boss engages with the groove and protrusion features regardless of the specific angle, allowing the same sizer design to work with different hanger configurations
Solution Approach 2:
The design allows for parameter changes in the engagement geometry of the protrusion boss to accommodate different hook angles. By adjusting the angular parameters of the boss and groove interface, the sizer can be adapted to work with hooks at various angles while maintaining secure attachment

AI summary
A crown-type sizer is suitable for mounting on a hanger having a body and a hook extending from a mid-point of the body and includes a peripheral wall having a first side and a second side opposed to the first side. The sizer includes a quantity of bosses that have at least one boss in a first set and at least one boss in a second set. The first set is disposed on the first side and the second set is disposed on the second side. Each of the bosses engages onto the hanger and block the sizer onto the hanger in a stable manner. The first set of bosses is offset to the second set of bosses with respect to a plane bisecting the first and the second side.
