Solution Overview
Problem
Existing cutting boards with rigid edges are problematic for food preparation as they inhibit the use of knives and do not effectively prevent spills of juices and solid debris during food preparation.
Innovation Solution
A spill-resistant cutting surface with a flexible flange that can be folded into a trough to channel liquids and solids into a disposal receptacle, while maintaining a smooth, germ-free surface for easy cleaning and allowing close proximity of cutting tools without spilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid edges are provided on the cutting surface, then liquid retention is improved, but knife usage near edges is inhibited
Solution Approach 1:
The patent applies a flexible flange made of elastomeric material around the cutting surface perimeter. This flexible edge provides liquid retention through its ability to conform and seal, while simultaneously allowing knife contact without the inhibition caused by rigid edges. The flexibility enables the material to deform under knife pressure rather than resisting, thus solving both the spill prevention and knife usability problems.
Solution Approach 2:
The patent changes the physical state parameter of the edge material from rigid to flexible/elastomeric. This parameter change allows the edge to exhibit both liquid containment properties (through flexibility and conformability) and knife-friendly properties (through softness and deformability under cutting tool pressure).
2Reliability
If rigid edges are used to prevent spills, then liquid containment is improved, but the cutting surface becomes less adaptable to cutting tool contact
Solution Approach 1:
The flexible flange acts as an adaptable interface that can conform to various cutting tool shapes and sizes. Its elastomeric nature allows it to deform and adapt to different knife profiles, providing consistent spill protection while accommodating diverse cutting tools without the rigidity constraints of traditional hard edges.
3Object-affected harmful factors
If a smooth continuous surface is created, then germ collection is minimized, but liquid channeling capability is reduced
Solution Approach 1:
The patent segments the surface into two distinct functional zones: a smooth central cutting area for germ-free preparation, and a textured peripheral flange area for liquid channeling and disposal. This segmentation allows each zone to optimize its specific function without compromising the other, maintaining both sanitary cutting surface and effective liquid management.
Solution Approach 2:
The patent applies different surface qualities to different locations: the central cutting surface maintains smoothness for hygiene, while the peripheral flange incorporates texture for liquid management. This local differentiation of surface properties resolves the contradiction between germ minimization and liquid channeling by assigning each quality to its most appropriate location.

AI summary
The food processor apparatus comprises a spill-proof cutting surface and includes a cutting surface and a flexible flange attached to the cutting surface. The flexible flange is bendable and creates a raised rim around the cutting surface. The flexible flange is itself liquid-proof and is attached to the cutting surface in a liquid-proof manner.
