Solution Overview

Problem

The conventional method of manufacturing rainbow stick toys is labor-intensive and costly, with low productivity, resulting in inconsistent quality and shape issues due to manual bonding of strip members to bonding members, leading to difficulties in mass production and sales promotion.

Innovation Solution

A method involving the formation of coupling slits and protrusions on continuous regions of a flexible sheet, allowing for automated production of ornament strips that can be easily coupled into rings, improving productivity and reducing costs, and incorporating stopper plates and snag-proof plates for better shape control and entanglement prevention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If manual bonding method is used to attach strip members to bonding members, then flexibility and simplicity of structure are maintained, but productivity is very low and manufacturing cost is high

Engineering Contradiction:
Improvesimplicity of structureVSAvoidproductivity
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The continuous flexible sheet is segmented into multiple strip members by forming coupling slits between them, allowing automated processing while maintaining the flexibility of the overall structure. This segmentation enables machine processing instead of manual bonding, significantly improving productivity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling slits are formed in advance during the sheet processing stage, before the strip members are assembled into the final product. This preliminary action of creating the slits allows for automated coupling later, eliminating the need for manual bonding operations during final assembly.

AI summary

A method of manufacturing an ornament includes: providing a pair of continuous regions (11) facing one another in a flexible sheet (1); forming a plurality of slits (10) between the pair of continuous regions (11) to form a plurality of ornament strips (13), wherein the plurality of ornament strips (13) are separated from each other while both ends of the plurality of ornament strips (13) are integrally formed with the pair of continuous regions (11); and reversing the plurality of ornament strips (13) with respect to the pair of continuous regions (11) such that the plurality of ornament strips (13) radiate to form into an arc between the pair of continuous regions (11), while coupling each of the pair of continuous regions (11) to be formed into a ring.
