Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single plane cutter assembly is used for cutting fruits and vegetables, then the device complexity is low, but the particle size uniformity is poor leading to low juicing yield
Solution Approach 1:
The patent transitions from a single-plane cutter assembly to a multi-layer cutter assembly with first and second cutting discs arranged in different spatial planes. The first cutting disc has cutting edges on its upper surface and the second cutting disc has cutting edges on its lower surface, creating a three-dimensional cutting structure. This dimensional change enables particles to be cut from multiple angles and passes, significantly improving particle size uniformity and juicing yield while maintaining reasonable device complexity through the systematic arrangement of cutting elements.
2Productivity
If a high-speed rotatable cutter assembly is used for separation, then the separation speed is high, but incomplete cutting occurs causing juicing waste
Solution Approach 1:
The multi-layer cutter assembly performs preliminary cutting actions on fruits and vegetables before they reach the separation stage. The first cutting disc initially cuts the fed materials, and the second cutting disc further refines the particles. This preliminary multi-stage cutting ensures that particles are sufficiently reduced in size before separation, preventing incomplete cutting and associated juicing waste while maintaining high productivity through the continuous cutting and separation process.
3Manufacturing precision
If a single cutting plane is used, then the cutting mechanism is simple, but the cutting completeness is insufficient reducing juicing efficiency
Solution Approach 1:
The cutting function is segmented into multiple independent cutting discs, each with its own cutting edges arranged in specific patterns. The first cutting disc contains cutting edges on its upper surface while the second cutting disc contains cutting edges on its lower surface. This segmentation allows each cutting disc to perform specific cutting tasks, achieving comprehensive and complete cutting of fruits and vegetables. The segmented design improves cutting completeness and juicing efficiency while keeping the overall device complexity manageable through modular construction.

Function Achieved in This Case
The three-dimensional cutting mechanism effectively reduces particle size, improving juicing yield and minimizing waste by ensuring complete cutting and separation of pomace from juice.
Implementation Method 1
the cutter assembly rotates at a high speed to cut fruits and vegetables which are fed from an inlet of the cap
Implementation Method 2
The cutter assembly separates the pomace from the juice by using a rotatable centrifugal force at the high speed

AI summary
A fruit and vegetable juicer contains: a first holder, a second holder, a filtration mesh, a cutter assembly, and a cap. The second holder includes a drive shaft configured to connect with the cutter assembly so that the cutter assembly rotates at a high speed to cut fruits and vegetables which are fed from an inlet of the cap. The cutter assembly includes a first cutting disc and a second cutting disc. The first cutting disc has a toothed layer surrounding around a peripheral side thereof, a circular orifice defined on a central portion of the first cutting disc, and multiple spaced recesses. The second cutting disc has multiple central teeth, multiple toothed rows radially extending outward from the multiple central teeth, the toothed layer radially extending inward around a peripheral side of the second cutting disc, and the multiple spaced cutouts.
