Fabric Pom-Pom Structure With Long Fingers and Secure Sheet Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pom-poms have a large core and short fingers, making them less effective for dusting, washing, and polishing, as the fabric sheets are not securely held in place, leading to removal issues and difficulty in retightening the tie.
Innovation Solution
A pom-pom design with a small core and long fingers, using flexible sheets held by a tightening tie to form a soft, compressible body with curls for material retention and dispensing, ensuring the sheets are locked in place for improved usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If conventional pom-poms are made with stacks of fabric sheets held by a circumferential tie, then the pom-pom structure is simple to manufacture, but the core occupies large volume and fingers are short, reducing effectiveness for dusting and washing
Solution Approach 1:
The pom-pom is segmented into distinct functional zones: a compact central core region and extended finger regions. The fabric sheets are arranged and tied such that the core occupies minimal space while the fingers extend outward to greater lengths, creating a segmented structure that optimizes both core compactness and finger reach for dusting and washing applications.
Solution Approach 2:
The design transitions from a uniform spherical structure to one with dimensional variation, where the fingers extend in radial directions from a compact core. This dimensional change allows the pom-pom to have a small core volume while maintaining long fingers in the radial dimension, effectively resolving the contradiction between core size and finger length.
2Reliability
If fabric sheets are held together by a circumferential tie in conventional pom-poms, then the structure is simple, but the sheets are not securely held in place and can be pulled from the pom-pom during use
Solution Approach 1:
Multiple fabric sheets are merged and combined at the central core region, where they are all gathered and secured by the circumferential tie. This merging of multiple sheets at a single location creates a secure anchor point that prevents individual sheets from being pulled away, as they are all interconnected through the central gathering point.
Solution Approach 2:
The fabric sheets are pre-gathered and pre-secured to the central core by the circumferential tie before the pom-pom is put into use. This preliminary securing action ensures that the sheets are firmly attached and positioned, preventing them from being pulled away during subsequent dusting or washing operations.
3Reliability
If the tie is retightened to compensate for sheet removal in conventional pom-poms, then sheet retention may be improved, but the process is difficult or impossible
Solution Approach 1:
The circumferential tie structure is designed to maintain its securing function without requiring user intervention for retightening. The tie is configured to distribute tension evenly across all gathered sheets, and its structure inherently maintains sheet retention during use, eliminating the need for users to retighten it to compensate for sheet removal.
4Ease of operation
If conventional pom-poms have a large core, then the structure is stable, but the body is less compressible and harder to grip
Solution Approach 1:
The pom-pom body is segmented into a compact core region and extended finger regions. This segmentation allows the core to remain small and stable while the overall body structure becomes more compressible and easier to grip, as the fingers can be compressed toward the compact core without resistance from a large core volume.

AI summary
A pom-pom has a plurality of flexible sheets with each sheet including fingers on opposite edges, two side-by-side strips between the fingers, a plurality of spaced links joining the strips and openings or slits between the links. A tie tightly surrounds the links to form the pom-pom.
