Solution Overview

Problem

Conventional cutting boards are cumbersome and difficult to store or carry during outdoor activities like boating and camping due to their large size and weight, making them impractical for packing and storage in limited spaces.

Innovation Solution

A foldable cutting board with pivotally connected sections in an accordion style, equipped with a knife sharpener and rubber feet, allowing for easy storage and use, and magnetic closures to secure the board when folded.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a cutting board has a large surface area to hold fish or game, then it provides sufficient working area, but it becomes difficult to store and carry

Engineering Contradiction:

Improvecutting surface areaVSAvoidstorage and carrying convenience

Core Design Contradiction:

Area of stationary objectVSEase of operation

Solution Approach 1:

The cutting board is divided into multiple sections that can be folded together. The board comprises several rectangular sections connected by hinges, allowing it to be collapsed into a compact form for storage while maintaining a large flat surface area when unfolded for use.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cutting board transitions from a static rigid structure to a dynamic foldable structure. The hinges enable the board to change its configuration between a fully extended flat surface for cutting and a compact folded state for portability, adapting to different operational needs.

Inventive Principle:

Principle #15Dynamics

2Strength

If a cutting board is made of heavy wood for durability, then it provides strength and stability, but it becomes difficult to pack and carry

Engineering Contradiction:

Improveboard durabilityVSAvoidboard weight

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

The board is segmented into multiple lighter sections rather than one large heavy piece. Each section can be made from lighter materials while the overall structure maintains strength through the distributed design and hinge connections.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cutting board uses composite construction with multiple materials including lighterweight materials for the board sections themselves, reducing overall weight while maintaining durability through the combination of materials and structural design.

Inventive Principle:

Principle #40Composite materials

3Area of stationary object

If a cutting board has a wide shape for sufficient surface area, then it can hold large fish or game, but it is awkward to carry and store in limited spaces

Engineering Contradiction:

Improvecutting surface areaVSAvoidboard portability

Core Design Contradiction:

Area of stationary objectVSShape

Solution Approach 1:

The wide board is divided into narrower sections that can be folded together. When folded, the sections stack to create a much narrower profile that fits easily into backpacks, tackle boxes, and vehicle storage spaces, while unfolding provides the full wide surface area needed for processing large fish or game.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The board utilizes the third dimension (vertical folding) to achieve compact storage. By folding the sections together along the vertical axis, the board reduces its horizontal footprint dramatically while maintaining the same total surface area, effectively trading horizontal space for vertical arrangement.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

4Stability of the object's composition

If a cutting board is designed as a single rigid piece for stability during cutting, then it provides cutting stability, but it cannot be folded for compact storage

Engineering Contradiction:

Improvecutting stabilityVSAvoidfolding mechanism complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The cutting board employs a dynamic hinge mechanism that provides rigidity and stability when the board is in the unfolded cutting position, while allowing easy folding when not in use. The hinges are designed to maintain firm connections during cutting operations but enable smooth collapsing for storage.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The board integrates multiple functions into a single structure: the hinges serve both as structural connectors that provide stability during cutting and as folding mechanisms that enable compact storage. The design merges the structural support function with the portability function in one integrated system.

Inventive Principle:

Principle #5Merging (Combining)
