Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional envelopes are environmentally wasteful and costly due to single-use design, while existing origami envelopes are impractically shaped, difficult to construct, and often require irregularly sized paper, making them less functional and more prone to loss in the mail.
Innovation Solution
A method and structure for forming an origami envelope using a rectangular sheet of material with specific folding lines, allowing for easy construction into a conventional envelope shape using standard paper sizes, reducing the need for additional tools like scissors and enabling easy insertion and secure closure of contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If conventional envelopes are used, then envelope functionality is provided, but environmental waste and cost increase due to single-use design
Solution Approach 1:
The patent enables recovery and reuse of the envelope structure by designing it to be foldable and reusable. The origami envelope can be opened, contents removed, and the envelope itself retained for future use, directly addressing the single-use waste problem of conventional envelopes.
Solution Approach 2:
The envelope transitions from a static single-use structure to a dynamic reusable structure through its foldable design. The multiple fold lines allow the envelope to be opened and closed repeatedly, changing its state between sealed and open configurations while maintaining structural integrity.
2Loss of substance
If existing origami envelopes are folded to create unique shapes, then environmental friendliness improves, but functionality and shape regularity deteriorate
Solution Approach 1:
The origami envelope is designed to serve multiple functions: it can hold letters, cards, small gifts, and other items. The standardized shape with regular flaps and closure mechanisms makes it universally applicable for various mailing needs while maintaining environmental benefits.
Solution Approach 2:
The envelope employs asymmetric fold patterns that create a regular, conventional envelope shape from a square sheet. The fold lines are strategically positioned to produce symmetric-looking flaps and edges, transforming the symmetric square input into an asymmetric functional envelope form.
3Ease of operation
If existing origami envelopes are constructed from irregular shaped paper, then envelope functionality is achieved, but construction time and complexity increase
Solution Approach 1:
The invention changes the parameter of paper shape from irregular to square, and modifies the fold pattern parameters to work specifically with square paper. This standardization allows the envelope to be constructed from readily available square paper without requiring manual tracing or cutting, significantly reducing construction time.
Solution Approach 2:
The fold lines are pre-determined and marked on the square paper before folding begins. This preliminary marking guides the folding process, eliminating the need for operators to manually trace irregular templates and reducing construction complexity while maintaining full envelope functionality.
4Ease of manufacture
If square-sized paper is used for origami envelopes, then construction simplicity improves, but paper availability deteriorates
Solution Approach 1:
The envelope design is universal and can be constructed from various standard paper sizes including square, rectangular, and different dimensions. The fold pattern adapts to different paper sizes while maintaining the same functional envelope structure, making the construction method widely applicable.
Solution Approach 2:
The invention allows flexibility in paper size parameters while maintaining the same fold construction method. The fold lines and flap configurations can be adjusted proportionally for different paper dimensions, enabling construction from commonly available paper sizes beyond just square paper.
5Loss of substance
If oddly-shaped folded envelopes are created, then environmental friendliness improves, but reliability in mail delivery deteriorates
Solution Approach 1:
The envelope is designed with regular, conventional shapes that are equally suitable for various mailing scenarios. The standardized form factor ensures consistent performance in mail handling, sorting, and delivery processes, eliminating the reliability issues associated with oddly-shaped envelopes while maintaining environmental benefits.
