Solution Overview

Problem

Existing portable sewing tool kits are inconvenient for cutting and ironing due to fixed cutting mats that require wrist or body movement for arc and curve cuts, and inflexible ironing mats that are difficult to replace and clean.

Innovation Solution

A portable patchwork sewing tool kit with a base plate that has foldable pages, a rotary cutting mat with a pivot joint base for easy rotation, and a detachable ironing mat with a core board and cotton fabric surface, allowing for improved portability, flexibility, and ease of use and cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a fixed cutting mat is used, then the structure is simple and stable, but the user must turn the wrist or move the body to cut arc, round or curve shapes, leading to inconvenient cutting

Engineering Contradiction:

Improvecutting convenienceVSAvoidcutting mat structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The cutting mat is designed with a rotary mechanism that allows it to rotate around a vertical axis. The cutting mat can be rotated to different angles using a rotating mechanism including a rotating plate, connecting arms, and sliding components, enabling the user to cut curves and arcs by rotating the mat rather than moving the wrist or body, thus improving cutting convenience while adding controlled complexity to the structure

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If the ironing mat is fixed, then the structure is stable, but the flexibility for replacement and cleaning is poor

Engineering Contradiction:

Improvereplacement and cleaning convenienceVSAvoidironing mat structure

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The ironing mat is designed as a detachable component that can be separated from the base plate. It includes an ironing mat body with an ironing surface that can be removed and replaced independently, allowing easy cleaning and replacement while maintaining the stability of the overall device structure through the base plate and connecting mechanisms

Inventive Principle:

Principle #1Segmentation

3Weight of moving object

If a portable sewing tool kit is made compact, then portability is improved, but the area of the cutting mat and ironing mat is reduced

Engineering Contradiction:

ImproveportabilityVSAvoidcutting and ironing surface area

Core Design Contradiction:

Weight of moving objectVSArea of stationary object

Solution Approach 1:

The cutting mat is designed to rotate vertically around a vertical axis, utilizing the vertical dimension for storage and operation. When not in use, the cutting mat can be rotated to a vertical position, allowing the base plate to fold flat, thus reducing the overall footprint and improving portability while maintaining full cutting surface area when deployed

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
