Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the distance between stator and rotor pulverizing surfaces is fixed, then the structure is simple, but the pulverizer cannot meet different particle size requirements

Engineering Contradiction:
Improveapplicability to different particle sizesVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the distance between the stator and rotor pulverizing surfaces adjustable rather than fixed. The stator can be moved relative to the rotor along the axial direction, allowing the pulverizing gap to be dynamically changed according to different particle size requirements. This transforms a static structure into a dynamic one, enabling the pulverizer to adapt to various processing needs while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the stator is directly fixed to the support frame, then the structure is simple, but the pulverizing surface distance cannot be adjusted

Engineering Contradiction:
Improveadjustability of pulverizing surface distanceVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the connection between the stator and support frame into multiple components: the stator, a first box connected to the stator, and a second box connected to the support frame. The first box and second box can be detached and repositioned, allowing the stator to be adjusted relative to the rotor. This segmented design enables adjustability while keeping each individual component relatively simple.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the rotor is fixed tightly to ensure stability, then rotation stability is good, but maintenance and adjustment are difficult

Engineering Contradiction:
Improveease of maintenanceVSAvoidrotation stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies segmentation by separating the rotor assembly from the support frame through the second box, which can be detached. This allows the rotor to be easily removed for maintenance or adjustment by simply detaching the second box from the support frame, without requiring complex disassembly procedures. The rotor remains securely mounted during operation but can be quickly accessed when maintenance is needed.

Inventive Principle:
Principle #1Segmentation

AI summary

A pulverizer includes a support frame, a stator, and a rotor. The stator is connected to the support frame and has a stator pulverizing surface. The rotor is connected to the support frame and has a rotor pulverizing surface, and the rotor is rotatable. The stator pulverizing surface is opposite to the rotor pulverizing surface, a pulverizing chamber is formed between the stator pulverizing surface and the rotor pulverizing surface, and a distance between the stator pulverizing surface and the rotor pulverizing surface is adjustable.
