Solution Overview

Problem

Conventional envelopes are environmentally wasteful and costly due to their one-time use, while existing origami envelopes are often oddly shaped, impractical, and require irregularly sized paper, making them difficult to construct and less functional.

Innovation Solution

A method and structure for forming an origami envelope using a rectangular sheet of paper with specific fold lines, allowing for easy construction and functionality similar to conventional envelopes, using five or six folding actions without the need for scissors or additional tools, and accommodating various object sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If conventional envelopes are used, then envelope functionality is provided, but environmental waste and cost increase due to one-time use

Engineering Contradiction:

Improvepaper wasteVSAvoidreusability

Core Design Contradiction:

Loss of substanceVSAdaptability or versatility

Solution Approach 1:

The patent enables the envelope to be unfolded and reused multiple times by designing a flat-foldable structure that maintains its functional form after use, allowing the paper to be recovered and used again rather than discarded

Inventive Principle:

Principle #34Discarding and recovering

2Ease of manufacture

If existing origami envelope designs are used, then paper folding is simplified, but the envelopes become oddly-shaped and impractical

Engineering Contradiction:

Improvefolding simplicityVSAvoidenvelope shape

Core Design Contradiction:

Ease of manufactureVSShape

Solution Approach 1:

The patent pre-defines specific fold lines and crease patterns on the paper before folding, which guides the user through simple folding actions to achieve the desired conventional envelope shape without requiring complex manual shaping

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If irregular shaped paper is used for origami envelopes, then folding complexity increases due to manual tracing and cutting

Engineering Contradiction:

Improvepaper shape flexibilityVSAvoidpreparation time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent designs a universal folding pattern that works with standard rectangular paper sizes, eliminating the need for custom cutting or tracing while maintaining the ability to create functional envelopes from readily available paper

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Ease of manufacture

If square-sized paper is used for origami envelopes, then folding is simplified, but paper availability decreases

Engineering Contradiction:

Improvefolding easeVSAvoidpaper availability

Core Design Contradiction:

Ease of manufactureVSQuantity of substance

Solution Approach 1:

The patent modifies the folding parameters and fold line configurations to accommodate standard rectangular paper sizes (such as letter or A4 size) while maintaining the simplicity and functionality of the envelope construction process

Inventive Principle:

Principle #35Parameter changes

AI summary

An origami envelope and a method of constructing the origami envelope are enclosed. The origami envelope is quadrilateral in shape. The origami envelope comprises a top layer having a front surface and a back surface opposite to the front surface, and a bottom layer having an exterior side and an interior side opposite to the exterior side. The top layer extends to the exterior side of the bottom layer over a portion of the top envelope side to form a closure flap at the exterior side of the bottom layer.
