Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal components and additional mechanical connecting means are used in spice mills, then structural strength and durability are improved, but health safety deteriorates due to harmful metal chips and oils adhering to the ground material
Solution Approach 1:
The patent removes all metal components from the spice mill structure, extracting the harmful element entirely from the system. The grinder components, housing, and connecting means are all replaced with plastic or ceramic materials, eliminating the source of metal chips and contamination that would otherwise adhere to ground spices.
Solution Approach 2:
The patent changes the material parameters of the grinder components from metal to plastic/ceramic compositions. This material substitution maintains the functional requirements for grinding while fundamentally altering the chemical composition to be health-safe, preventing any harmful metal contamination of the ground material.
2Stability of the object's composition
If additional connecting means such as screws and bolts are used to assemble spice mill components, then assembly stability is improved, but device complexity and production cost increase
Solution Approach 1:
The patent merges the functions of separate connecting components into integrated structural designs. The housing and grinder components are designed as unified plastic parts with built-in alignment features and snap-fit connections, eliminating the need for separate screws, bolts, or clamping means. This integration maintains assembly stability while significantly reducing device complexity.
Solution Approach 2:
The patent implements self-assembling components with automatic alignment and locking features. The plastic housing parts and grinder components include built-in guide ribs, recesses, and snap-fit mechanisms that automatically align and secure parts during assembly without requiring external fastening tools or additional connecting means, enabling tool-free assembly while maintaining structural stability.
3Device complexity
If the grinder is made non-adjustable to simplify the structure, then device complexity is reduced, but adaptability in grain size control is lost
Solution Approach 1:
The patent transforms the static, fixed grinder design into a dynamic, adjustable system. The grinder components are designed with movable elements that allow users to change the grinding gap and adjust grain size output. This dynamic capability provides versatility in grain size control while maintaining relatively simple plastic construction through integrated adjustment mechanisms.
4Manufacturing precision
If traditional assembly methods with multiple fastening means are used, then manufacturing precision can be maintained, but productivity decreases due to time-consuming assembly processes
Solution Approach 1:
The patent implements self-assembling components with automatic alignment and locking features. The plastic housing parts and grinder components include built-in guide ribs, recesses, and snap-fit mechanisms that automatically align and secure parts during assembly without requiring external fastening tools or additional connecting means, enabling tool-free assembly while maintaining structural stability.
Solution Approach 2:
The patent incorporates preliminary alignment features directly into the molded plastic components during manufacturing. Guide ribs, positioning recesses, and pre-formed connection interfaces are integrated into the part designs before assembly, ensuring precise alignment and proper positioning are achieved automatically during the assembly process without requiring additional precision-fastening operations.
