Rice Wrapper Dividable Outer Film for One-Handed Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing rice wrappers require cumbersome steps for removal, as the outer film needs to be divided along a dividable section, which can be covered by the outer wrapping part, making it difficult to separate and handle the wrapped rice efficiently.
Innovation Solution
A rice wrapper design featuring an outer film with a strip-shaped dividable section extending its entire length, where the inner films are displaced and heat-sealed, allowing for easy separation of the outer film into two parts by pulling the dividable section, ensuring the outer wrapping part does not cover the entire length, facilitating stable handling and easy division.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the outer film is divided into two along a dividable section, then the wrapped rice can be separated into two parts, but the removal process becomes cumbersome and complex
Solution Approach 1:
The outer film is divided into two parts along a dividable section, allowing the wrapped rice to be separated into two portions. This segmentation enables independent handling and removal of each side, simplifying the overall removal process while maintaining ease of operation.
Solution Approach 2:
The dividable section is extracted as a specific feature of the outer film, creating a designated separation line that facilitates easy division. This extracted feature allows users to cleanly separate the wrapped rice without complex manual manipulation, reducing operational complexity.
2Reliability
If the outer wrapping part covers the entire length of the outer film, then the wrapped rice is securely enclosed, but the dividable section becomes covered and difficult to access for division
Solution Approach 1:
The outer wrapping part is designed with varying coverage: it covers most of the outer film length to provide secure enclosure, but intentionally leaves the dividable section exposed or partially exposed. This local quality differentiation ensures both reliable enclosure and easy access to the division line for user operation.

Function Achieved in This Case
This design simplifies the removal process by allowing one side part to be separated from the other in one action, enabling stable holding and easy division of the outer film, reducing cumbersome steps and ensuring the wrapped rice can be held and divided efficiently with one hand.
Implementation Method 1
the inner films may be fixed to the outer film by heat seal

AI summary
The present invention provides a rice wrapper, in which an outer film divided into two can be easily removed. One side part of the rice wrapper 10, which includes one part of the outer film divided along the dividable section and an inner film 16a connected to the one part thereof, is separated from the other side part of the rice wrapper, which includes the other part of the outer film divided and an inner film 16b connected to the other part thereof, when the outer film 14 is divided along the dividable section 12, and a part of the dividable section 12 is connected to the one side part, and the one side part can be separated from the other side part, in one action, by pulling the dividable section 12.
