Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If high compression force is applied to fracture rocks with high stress thresholds, then the rock crushing capability is improved, but the energy consumption and time required increase significantly

Engineering Contradiction:

Improverock crushing capabilityVSAvoidenergy consumption

Core Design Contradiction:

StrengthVSUse of energy by moving object

Solution Approach 1:

The patent introduces a vibratory mechanism that applies high-frequency vibrations to the compression assembly, enabling the system to fracture rocks more efficiently. The vibrations create dynamic stress cycles that propagate through the rock material, reducing the peak compression force needed and thereby decreasing energy consumption while maintaining effective rock crushing capability.

Inventive Principle:

Principle #18Mechanical vibration

Solution Approach 2:

The patent employs periodic compression cycles combined with vibratory motion to fracture rocks. Instead of applying continuous high compression force, the system uses repeated compression-relaxation cycles with vibratory enhancement, which accumulates stress in the rock over time and facilitates fracture at lower energy input levels.

Inventive Principle:

Principle #19Periodic action

2Strength

If high compression force is applied to fracture rocks with high stress thresholds, then the rock crushing capability is improved, but the time required for crushing increases

Engineering Contradiction:

Improverock crushing capabilityVSAvoidcrushing time

Core Design Contradiction:

StrengthVSLoss of time

Solution Approach 1:

The vibratory mechanism accelerates the rock crushing process by introducing high-frequency oscillations that create micro-fractures and propagate stress waves through the rock material. This significantly reduces the time required for rocks to reach their fracture point under compression, while maintaining the necessary crushing capability.

Inventive Principle:

Principle #18Mechanical vibration

Solution Approach 2:

The patent utilizes rapid periodic compression cycles enhanced by vibrations to fracture rocks more quickly. The repeated stress cycles, amplified by vibratory motion, accelerate the failure process of the rock, reducing the overall crushing time compared to static compression methods.

Inventive Principle:

Principle #19Periodic action

3Productivity

If high compression force is continuously applied to crush large volumes of material, then the productivity is improved, but the stress on equipment increases significantly

Engineering Contradiction:

Improvematerial processing throughputVSAvoidequipment stress

Core Design Contradiction:

ProductivityVSStress or pressure

Solution Approach 1:

The vibratory mechanism reduces equipment stress by distributing the loading more evenly over time through high-frequency oscillations. The vibrations prevent stress concentration and reduce the peak forces transmitted to the equipment structure, enabling continuous operation at high productivity levels without excessive stress accumulation.

Inventive Principle:

Principle #18Mechanical vibration

Solution Approach 2:

The patent employs periodic compression cycles with vibratory enhancement to process large volumes of material sustainably. The rhythmic application of force with vibratory intervals allows equipment to recover between peaks, reducing cumulative stress and heat generation while maintaining high throughput capability.

Inventive Principle:

Principle #19Periodic action

AI summary

A rock crushing device includes a housing with a plurality of walls defining a chamber that has an upper inlet and a lower outlet. At least one of the walls is movable relative to another wall to define a primary compression assembly for crushing rocks within the chamber via mechanical force. There is an auxiliary crushing assembly connected with at least one of the walls to deliver a vibratory force to at least one wall for crushing rocks within the chamber. The auxiliary crushing assembly is operable together with the primary compression assembly or independent of it.
