Solution Overview

Problem

Diagonal wrapping of gifts is challenging due to difficulties in determining the size of packaging paper, initial positioning, and angle relative to the box, and requires skilled techniques for ribbon tying.

Innovation Solution

A creasing tool with hinged panels and a reference line for precise paper folding, and a ribbon-tying tool with specific sections for forming knots, facilitating easy and aesthetic wrapping and knot-tying processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If diagonal wrapping method is used, then wrapping speed increases and adhesive tape usage decreases, but it becomes difficult to determine packaging paper size, initial position, and angle

Engineering Contradiction:

Improvewrapping speedVSAvoidpackaging paper size determination

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The creasing tool serves as an intermediary device between the wrapper and the packaging paper, providing pre-marked guidelines and angle references that mediate the complex measurements required for diagonal wrapping, making it easier to achieve accurate results without extensive calculation

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The creasing tool incorporates pre-drawn reference lines and angle markings that are prepared in advance, allowing the wrapper to directly follow the pre-calculated guidelines rather than performing measurements and calculations during the wrapping process

Inventive Principle:

Principle #10Preliminary action

2Productivity

If diagonal wrapping method is used, then wrapping efficiency improves, but double-layered pleats must be made making it difficult to master

Engineering Contradiction:

Improvewrapping efficiencyVSAvoidfolding technique difficulty

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The creasing tool acts as a physical guide that mediates the complex double-layered pleat folding process, providing visual and tactile references that simplify the execution of difficult folding techniques

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention replaces the need for skilled manual folding techniques with a mechanical guiding system consisting of hinges and reference lines that automatically indicate the correct folding paths and angles

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Shape

If ribbon knot-tying is performed manually, then decorative effect is achieved, but it requires difficult techniques to master

Engineering Contradiction:

Improveknot appearanceVSAvoidknot-tying technique

Core Design Contradiction:

ShapeVSEase of operation

Solution Approach 1:

The knot-tying tool is designed to perform the complex knot-tying operations automatically once the ribbon is positioned, allowing users without specialized skills to achieve professional-looking results through simple tool operation

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The invention replaces skilled manual knot-tying techniques with a mechanical device that uses levers, guides, and tensioning mechanisms to automatically form decorative knots

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
