Donut Cutting and Holding Device with Pivot Scissors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for cutting and serving donuts are often unhygienic and clumsy, as they require users to hold the donut with their hands while cutting it, leading to potential contamination and difficulty in obtaining uniform portions.
Innovation Solution
A device comprising a first scissors member and a second scissors member, operatively connected via a pivot member, designed to cut, hold, and serve donuts, with optional donut engagement members to secure the donut in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a knife is used to cut the donut, then the donut can be divided into smaller portions, but the user must hold the donut with their hands which leads to non-hygienic interaction and potential contamination
Solution Approach 1:
The device introduces an intermediary tool (the holder with clamp) between the user's hand and the donut. The clamp securely grips the donut, allowing the user to cut with a knife while the holder prevents direct hand contact with the food surface, thus eliminating contamination risk while maintaining cutting functionality
Solution Approach 2:
The holder device is designed to be self-holding through its clamp mechanism that secures the donut in place. The weight distribution and grip design allow the device to hold itself steady during cutting without requiring additional support or manual adjustment, enabling autonomous operation
2Object-affected harmful factors
If utensils are used to cut donuts, then hygiene is improved, but the utensils are clumsy and not very intuitive when used to cut donuts
Solution Approach 1:
The device merges two separate functions into one unified tool: the holder that grips the donut and the support structure for the knife. This combination creates a coordinated system where the holder and knife work together as an intuitive unit, eliminating the clumsiness of separate utensils while maintaining hygiene benefits
Solution Approach 2:
The device adds a vertical dimension to the cutting operation by using a holder that extends upward from the donut surface. This allows the knife to approach from above in a natural downward motion, rather than requiring lateral or awkward movements, thereby improving intuitiveness while maintaining the hygienic barrier
3Manufacturing precision
If the device includes donut engagement members to secure the donut, then cutting precision is improved, but device complexity increases
Solution Approach 1:
The engagement mechanism is segmented into discrete, simple components (clamps or grips) that can be independently positioned on the holder. This segmentation allows for precise positioning of the donut without requiring a complex overall structure, as each segment contributes a specific function to the securing process
Solution Approach 2:
The engagement members provide localized gripping force at specific points on the donut surface rather than requiring uniform control across the entire device. This localized approach achieves precise positioning and secure holding with minimal structural complexity, as only the critical contact points are engineered for precision

AI summary
Devices for use with food, preferably donuts, are provided. The devices are designed to allow a user to cut a donut, to hold a donut or portions thereof, to be used to serve a donut or portions thereof, or combinations thereof. In one embodiment, the donut cutter may comprise a first scissors member and a second scissors member. The first scissors member and the second scissors member are operatively connected via a pivot member to allow the donut cutter to move between various orientations. In another embodiment, the donut cutter may comprise a first arm and second arm. The first arm and the second arm are linked tougher via a wall or segment at the first end.
