Flexible U-Shaped Cutting Board to Contain Scattered Food Particles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Chopping brittle foods on traditional flat cutting boards results in scattered particles and inefficient processing, as they tend to break and disperse, requiring manual repositioning and additional cleaning challenges due to sticking residues.
Innovation Solution
A flexible cutting board configured in a U-shape, either manually held or secured by a holder, to contain chopped particles and allow un-chopped items to fall into a collectible area, preventing scattering and facilitating continuous chopping without interruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a flat cutting board is used to chop brittle foods, then the chopping process can be initiated, but the chopped particles scatter and disperse, requiring manual repositioning and reducing efficiency
Solution Approach 1:
The cutting board is transformed from a flat surface to a curved U-shaped configuration. This curvature creates a bowl-like structure that contains chopped particles at the bottom, preventing them from scattering across the workspace. The curved sides naturally guide and collect both chopped and unchopped items, allowing continuous chopping without manual repositioning.
Solution Approach 2:
The cutting board transitions from a two-dimensional flat surface to a three-dimensional U-shaped structure with vertical sides. This dimensional change creates depth and containment, forming a natural collection area at the bottom where chopped particles accumulate, enabling uninterrupted chopping operations.
2Productivity
If brittle foods are chopped on a flat surface, then cutting can occur, but particles fly off the board due to impact forces
Solution Approach 1:
The U-shaped curved configuration creates containing walls that intercept and redirect flying particles back toward the center bottom area. The curvature geometry naturally funnels scattered particles into the collection zone, preventing them from leaving the cutting area.
Solution Approach 2:
The impact forces that cause particles to fly off are converted into a beneficial effect by the curved geometry. The same forces that scatter particles on a flat board now cause them to bounce off the curved sides and settle into the bottom collection area, transforming a harmful scattering effect into a useful particle collection mechanism.
3Ease of operation
If un-chopped and chopped pieces are mixed on a flat board, then all items are in one area, but they must be physically pushed together to maintain effective chopping
Solution Approach 1:
The curved U-shape creates a natural convergence zone at the bottom where all items are funneled together by the sloping sides. This geometry automatically concentrates both chopped and unchopped pieces in the optimal chopping area without requiring manual gathering or repositioning.
Solution Approach 2:
The curved cutting board structure performs the gathering function automatically through its geometry. The sloping sides self-directed items toward the bottom center during normal chopping operations, eliminating the need for the user to manually push or gather pieces together.
4Object-generated harmful factors
If a flexible cutting board is bent into a U-shape, then particle containment is achieved, but the board structure becomes more complex
Solution Approach 1:
The cutting board is designed to be flexible and dynamically configurable. It can be bent into a U-shape for contained chopping operations and then flattened for storage or alternative uses. This dynamic adaptability allows the simple flexible material to provide complex functionality when needed while maintaining simplicity for storage.
Solution Approach 2:
A flexible cutting board material is used that can be easily bent and shaped without breaking or permanent deformation. This flexible shell approach allows the creation of the U-shaped containing structure from a simple, lightweight material that maintains structural integrity during use and returns to flat form for storage.

AI summary
A method of chopping or cutting a food item on a cutting board which involves configuring and holding a flexible cutting board in a U-shaped configuration and chopping or cutting a food item in the bottom of the U-shaped configuration. Particles of the food item that would otherwise traject off a flat cutting board are contained between the side walls of the U-shaped configuration of the flexible cutting board and un-chopped and un-cut pieces of the food item fall downward into the bottom of the U-shaped configuration of the flexible cutting board. Also provided is the combination of a flexible cutting board and a cutting board holder that receives and holds a flexible cutting board in the U-shaped configuration.
