Adjustable-Depth Fruit and Vegetable Peeler for Thick-Skinned Produce
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fruit and vegetable peeling and carving tools are not well-suited for handling tough or thick-skinned fruits and vegetables like mangos, pineapples, and watermelons, as they fail to efficiently remove the skin or carve through the fruit without wasting the edible parts or causing injury.
Innovation Solution
A fruit and vegetable peeler and carving tool with a handle and adjustable blades that form a convex and concave peeling and carving blade, allowing for adjustable peeling and carving depth settings, enabling efficient skin removal and slicing of thicker-skinned fruits and vegetables while avoiding the core or seeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional knives, peelers, or carving tools are used on tough or thick-skinned fruits and vegetables, then the tools can penetrate the skin, but they waste edible parts or cause injury due to inability to control depth
Solution Approach 1:
The blade assembly is made adjustable and movable relative to the handle through a depth control mechanism. The blade can be positioned at different depths along the handle axis, allowing dynamic adjustment of peeling and carving depth to match different fruit/vegetable sizes and skin thicknesses, preventing both insufficient penetration and excessive cutting that wastes edible parts
Solution Approach 2:
The tool changes the parameter of blade position/depth relative to the handle. By providing multiple fixed depth positions or continuous adjustability, the tool adapts to different skin thicknesses and fruit sizes, enabling precise control over how deep the blade penetrates without cutting into the edible interior
2Productivity
If conventional tools are used on thick-skinned fruits, then they can remove the skin, but the tools lack the structural design to efficiently handle tough skins without slipping or requiring excessive force
Solution Approach 1:
The tool combines a rigid blade made of hard material (capable of cutting tough skin) with a handle that may incorporate gripping surfaces or materials. This composite construction allows the blade to efficiently penetrate thick skin while the handle provides ergonomic control, reducing the effort needed and preventing slippage during operation
Solution Approach 2:
The blade is designed with a curved or contoured cutting edge that follows the natural curvature of fruits and vegetables. This curved geometry allows the blade to conform to the fruit surface, maintaining consistent contact and cutting pressure along the skin, improving skin removal efficiency while requiring less operational force compared to a straight blade
3Manufacturing precision
If conventional tools are used for carving, then they can cut through the fruit, but they cannot create consistent slices or avoid cores/seeds due to lack of depth adjustment mechanism
Solution Approach 1:
The depth control mechanism provides dynamic adjustability of the blade position relative to the handle. This allows the user to set the blade depth to match the distance from the skin to the core or seeds, ensuring consistent slices are carved without cutting into the inedible center, while the adjustable nature accommodates different fruit sizes and shapes
Solution Approach 2:
The tool separates the blade function from the handle, allowing independent adjustment of blade position. This segmentation enables the blade to be positioned at optimal depths for different carving tasks (peeling vs. slicing vs. coring) while the handle remains stable and ergonomic, achieving precision without excessive overall complexity

AI summary
A fruit and vegetable peeler and carving tool has a handle with a first side and second side extension extending from the front of the handle. Each side extension has a forward lever which is positionably affixed at a forward vertical plurality of lever affixment position, and a rear lever which is positionably affixed at a rear horizontal plurality of lever affixment position. The forward lever and the rear lever of each side are connected together in parallel with a depth adjustment rod is connected between them. A triangular handle-facing fruit and vegetable peeling and carving blade has a convex upper surface and a concave lower surface. By drawing the fruit and vegetable peeler and carving tool into a fruit or vegetable, the triangular handle-facing fruit and vegetable peeling and carving blade cuts into the fruit or vegetable to a depth controlled by the position of the depth adjustment rod.
