Nestable Hanger Design to Reduce Packaging Volume and Shipping Cost
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inefficiency in packing hangers for shipping results in excessive air space, leading to higher freight charges, and existing designs struggle to maintain structural integrity while minimizing additional plastic material.
Innovation Solution
A hanger design featuring a quasi-trapezoid shaped depression at the center with a groove and additional side support allows for stacking, reducing packaging size by approximately 30-35% without compromising structural strength or functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If traditional hanger design is used, then structural integrity is maintained, but packaging volume increases and shipping costs rise
Solution Approach 1:
The hanger design enables nested stacking where multiple hangers are placed one inside another or closely together in a vertical arrangement. The curved hook geometry allows each hanger to nest within the space created by adjacent hangers, significantly reducing the overall packaging volume required for shipping multiple units.
Solution Approach 2:
The hanger utilizes vertical stacking in the third dimension (height) rather than horizontal placement. By designing the hook and body geometry to allow vertical nesting, the packaging efficiency improves from two-dimensional side-by-side placement to three-dimensional stacked arrangement, reducing the footprint and overall package size.
2Quantity of substance
If additional plastic material is added to improve packing efficiency, then packaging density increases, but manufacturing cost increases
Solution Approach 1:
The hanger's own geometry and structure are designed to enable efficient packing without requiring additional packaging materials or components. The curved hook and body shape create natural nesting spaces that allow multiple hangers to pack tightly together using only the hangers themselves, eliminating the need for extra plastic dividers, inserts, or protective materials.
Solution Approach 2:
The hanger design modifies the geometric parameters of the hook and body sections to optimize packing efficiency. By adjusting the curvature radius, thickness distribution, and overall dimensions, the hanger achieves better nesting characteristics and packing density while maintaining structural integrity, all within the existing single-piece molded construction that keeps manufacturing simple and cost-effective.

AI summary
A hanger that is shaped to reduce packaging size by 30-50% is described. The amount of air in hanger packaging is minimized because each hanger has a “groove” that allows another hanger to sit on top as a “tongue” and save space. This significantly reduces the shipping cost of a set of hangers, while maintaining its utility as a hanger when in use.
