Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional knives are used to cut vegetables, then cutting can be performed, but the cutting effect is suboptimal with inconsistent sizes and shapes and low cutting efficiency
Solution Approach 1:
The cutting device is segmented into multiple cutting knife members (first, second, third, and fourth cutting knife members) with blade groups arranged at different positions and orientations. Each cutting knife member handles a specific cutting task, dividing the overall cutting process into multiple sequential stages that collectively achieve uniform and efficient cutting results.
Solution Approach 2:
The blade groups are arranged in three-dimensional space with different orientations and positions. The first and second blade groups are arranged horizontally, while the third and fourth blade groups are arranged vertically, creating a multi-dimensional cutting structure that processes vegetables through multiple planes simultaneously.
2Manufacturing precision
If conventional vegetable choppers are used, then vegetables can be cut into uniform strips, but users need to exert a lot of force making it difficult to use
Solution Approach 1:
The pressing block is designed to move dynamically along the pressing direction, allowing users to apply force efficiently. The movable pressing block adapts to the vegetable material being processed, distributing the required force more effectively compared to fixed pressing mechanisms in conventional choppers.
Solution Approach 2:
The blade groups are arranged in multiple spatial dimensions with different orientations. The horizontal blade groups (first and second) and vertical blade groups (third and fourth) work in sequence, allowing the vegetable material to be progressively cut through multiple planes, reducing the force required at each individual cutting stage.
3Ease of operation
If conventional vegetable choppers are used, then cutting can be performed, but hand contact with cutting tools poses safety hazards
Solution Approach 1:
The pressing block serves as an intermediary between the user's hand and the cutting knife members. Users operate the device by moving the pressing block along the pressing direction, which indirectly actuates the cutting process without requiring direct hand contact with the blade groups, thereby eliminating safety hazards while maintaining ease of operation.
4Productivity
If multiple blade groups are stacked together, then cutting efficiency can be improved, but the blade groups may overlap reducing cutting effectiveness
Solution Approach 1:
The blade groups are arranged asymmetrically in three-dimensional space with different orientations and positions. The first and second blade groups are arranged horizontally at different heights, while the third and fourth blade groups are arranged vertically. This asymmetric arrangement ensures that blade groups do not overlap when viewed from any single direction, allowing all blades to remain effective while processing material simultaneously.

AI summary
A labor-saving vegetable cutter and a labor-saving vegetable chopper are related to the technical field of kitchen utensils. The labor-saving vegetable cutter includes a pressing block and a cutting knife assembly. The cutting knife assembly includes a plurality of cutting knife members stacked together. The cutting knife member includes blade groups, and the blade groups on the plurality of cutting knife member are arranged in an offset manner. When the pressing block presses fruits and vegetables to be cut towards the cutting knife assembly, the fruits and vegetables are sequentially cut by the blade groups on the plurality of cutting knife members. The blade groups of the plurality of cutting knife members are interlaced with each other to cut the fruits and vegetables into strip shapes with a parallelogram cross-section.
