Cutting Board with Hinged Fork Holders for Safe One-Handed Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cutting boards pose safety risks and operational challenges, especially for individuals with hand impairments, as they are often flimsy, limit multi-item cutting, and can result in plastic debris contamination during food preparation.
Innovation Solution
A cutting board with hinged fork holders and a palm grip rest, allowing secure placement of cutting articles, enabling safe and easy slicing of various vegetables and other items, and accommodating one or two-handed operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional slicing guides are used on cutting boards, then cutting guidance is provided, but the guides are flimsy and result in premature wear on the cutting surface and guides
Solution Approach 1:
The patent employs composite material construction for the slicing guides, combining materials with different properties to achieve both guidance functionality and enhanced durability. The guides are constructed to resist wear and deformation while maintaining their shaping function, resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
The slicing guides feature curved or angled surfaces designed to guide the knife blade through the food item. The specific curvature and angulation of the guides provide mechanical advantage and distribute cutting forces evenly, preventing premature wear while maintaining cutting guidance functionality.
2Productivity
If multi-blade cutters are used, then cutting capability is provided, but the tool requires one-handed operation which is unsafe
Solution Approach 1:
The patent introduces an intermediary holding mechanism - the fork holder - that secures the food item during cutting. This mediator allows the user to operate the knife with one hand while the other hand controls the fork holder, eliminating the unsafe one-handed operation requirement while maintaining multi-blade cutting capability.
Solution Approach 2:
The cutting system is segmented into separate functional components: the multi-blade cutter for cutting action, the fork holder for securing the food item, and the cutting board base for support. This segmentation allows each component to perform its specific function optimally while improving overall safety and operational control.
3Adaptability or versatility
If cutting scissors with integrated cutting board are used, then cutting function is provided, but the knife does not cut all the way through the vegetable cleanly
Solution Approach 1:
The patent employs dynamic slicing guides with adjustable angles and positions, allowing the knife blade to maintain optimal contact with the food item throughout the cutting stroke. The guides can be positioned at different depths and angles to ensure complete penetration and clean cutting, resolving the issue of incomplete cuts while maintaining cutting versatility.
4Ease of operation
If plastic slicing guides are used, then cutting guidance is provided, but the knife edge may cut off pieces of the slicing guide plastic which can fall into the food
Solution Approach 1:
The patent utilizes composite material construction for the slicing guides, combining materials with different properties to achieve both guidance functionality and enhanced durability. The guides are constructed to resist wear and deformation while maintaining their shaping function, resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
The slicing guides feature a textured or porous surface structure that reduces friction between the knife blade and guide surface. This minimizes the risk of the knife edge catching and cutting off pieces of the guide material, preventing plastic debris contamination while maintaining cutting guidance functionality.

AI summary
A cutting board apparatus is provided. The cutting board apparatus assists users with disabilities that would impede their ability to slice cutting articles. Additionally, the cutting board apparatus provides a safe cutting platform for new and inexperienced users. The cutting board apparatus contains a cutting board base, at least one hinge, and at least one cutting article holder. Each of the cutting article holders is hingedly connected adjacent to the cutting board base through one of the at least one hinge. The user can place a cutting article along the cutting board base. The user can then rotate the cutting article holder adjacent to the cutting article, where the cutting article holder will secure the cutting article in place atop the base. The user can then use any type of cutting implement to perform slicing operations without having their assist hand close to the cutting article.
