Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a telescopic rotating shaft with spring support is used to enable disassembly of the base and pressing cover, then the vegetable cutter can be disassembled, but the structure becomes complicated and inconvenient to use
Solution Approach 1:
The patent extracts the spring support mechanism from the rotating shaft structure, eliminating the need for springs while maintaining the telescopic function. The rotating shaft is designed to extend and retract through direct mechanical interaction between the base and pressing cover without requiring spring-based support, thereby simplifying the overall structure.
Solution Approach 2:
The rotating shaft is divided into multiple segments that can extend and retract relative to each other. This segmentation allows the shaft to achieve telescopic motion through simple mechanical interlocking between segments, eliminating the need for complex spring support mechanisms while maintaining the desired functionality.
2Adaptability or versatility
If the rotating shaft is extended and retracted through a driving gear and rack mechanism, then the telescopic function is achieved, but the overall structure remains complicated
Solution Approach 1:
The patent replaces the gear and rack mechanical system with a simpler direct mechanical interlocking mechanism. The rotating shaft segments interact through complementary geometric features that enable extension and retraction through straightforward mechanical motion, eliminating the need for complex gear and rack components.
3Ease of operation
If a telescopic rotating shaft with multiple components is used, then the disassembly function is enabled, but the disassembly process becomes inconvenient for users
Solution Approach 1:
The rotating shaft segments are pre-configured with complementary geometric features that automatically guide the extension and retraction motion. This preliminary design of the mechanical interfaces allows users to perform disassembly and assembly through simple, intuitive motions without requiring complex manipulation or alignment procedures.
