Flexible Hanger Sizer Jaws for Secure Size Tag Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Garment hangers without hook bosses lack a secure mechanism to prevent unintended or malicious removal of sizing information, leading to increased time and costs in inventory management and potential sizer breakage during reuse.
Innovation Solution
A sizer design featuring a pair of longitudinal walls with jaws that flex apart to securely attach and detach from hangers lacking hook bosses, utilizing a gap dimension equal to or greater than the hanger's web thickness and curved edges to prevent removal, while allowing easy mounting and dismounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sizer is used on hangers without hook bosses, then sizing information can be displayed, but the sizer can be unintentionally removed during handling or maliciously removed by shoppers
Solution Approach 1:
The sizer incorporates flexible jaws that can dynamically change their gripping force. During normal handling, the jaws maintain a secure grip on the hanger flange. When intentional removal is needed, the flexible nature of the jaws allows them to be deliberately displaced while still preventing accidental detachment.
Solution Approach 2:
The patent changes the physical state of the sizer from rigid to flexible by using elastomeric material. This parameter change allows the sizer to deform and conform to the hanger flange, creating friction-based retention that prevents unintended removal while still allowing intentional removal when needed.
2Reliability
If a secure mechanism is added to prevent sizer removal, then sizer retention improves, but the device complexity increases
Solution Approach 1:
The patent merges the sizer body and the securing jaws into a single integrated elastomeric component. This eliminates the need for separate securing mechanisms, hooks, or locking devices that would increase complexity. The entire sizer structure serves both the information display function and the securing function.
Solution Approach 2:
By changing the material parameter from rigid to flexible elastomer, the patent achieves securing functionality without adding mechanical complexity. The flexibility itself becomes the securing mechanism through friction and deformation, eliminating the need for additional securing components.
3Reliability
If the sizer is made secure and difficult to remove, then unintended removal is prevented, but intended removal by store clerks becomes difficult
Solution Approach 1:
The flexible jaws provide dynamic retention that adapts to the force applied. Under normal handling forces, the jaws maintain strong grip. When deliberate removal force is applied by store clerks, the flexible material allows the jaws to deform and release from the flange, enabling easy intended removal while maintaining security against accidental removal.
4Reliability
If the sizer is secured tightly to prevent removal, then sizer retention improves, but sizer breakage occurs during reuse
Solution Approach 1:
Changing the material from rigid to flexible elastomer fundamentally changes how the sizer handles retention and durability. The flexible material provides secure retention through friction and conformal contact while absorbing stresses through elastic deformation, preventing the breakage that would occur in rigid sizers during repeated use and removal.

AI summary
A sizer for a hanger lacking a hook boss includes a pair of longitudinal walls spaced apart from each other by a pair of end sections. The sizer may include a pair of protrusion, wherein a first is disposed on a first wall of the pair of longitudinal walls and directed toward a second wall of the pair of longitudinal walls. A first jaw is disposed on one of the pair of end section. The pair of longitudinal walls flexes apart when the jaw passes over a flange of the hanger. The first jaw includes a lower portion having a curved edge. The first jaw further includes an upper portion. The lower portion and upper portion meet at an abrupt jaw point.
