Solution Overview

Problem

Conventional vibration rippers face challenges in preventing vibrations from transferring up and down, front and back, and left and right due to the direct installation of driving motors, leading to increased size and reduced vibration isolation efficiency.

Innovation Solution

The implementation of a link structure with vibroisolating bodies and elastic members between the vibration body and outer body, including gas-filled air cushion systems, to absorb and disperse vibrations generated during lifting operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If a driving motor is directly installed on the vibrator, then the vibration force is effectively generated, but the size of the driving motor must be increased when the scale of the main body is increased, leading to increased overall size

Engineering Contradiction:
Improvevibration forceVSAvoidoverall size
Core Design Contradiction:
PowerVSVolume of moving object

Solution Approach 1:

The vibration isolation system is segmented into multiple independent vibroisolating bodies positioned at different locations (lower left end, lower right end, and upper end) of the vibration body. Each vibroisolating body independently handles vibration in specific directions, allowing the system to achieve effective vibration isolation without requiring a single large motor or isolation component.

Inventive Principle:
Principle #1Segmentation

2Object-affected harmful factors

If conventional vibration isolation means are used, then some vibration is dispersed, but it is difficult to prevent all vibrations that occur up and down, front and back, and left and right

Engineering Contradiction:
Improvevibration isolationVSAvoidvibration prevention completeness
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

Different vibroisolating bodies are installed at specific locations on the vibration body - the first at the lower left end, the second at the lower right end, and the third at the upper end. Each location experiences different vibration characteristics, and the localized installation ensures that vibrations in all directions (up and down, front and back, left and right) are effectively isolated.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent introduces multiple vibroisolating bodies as intermediary elements between the vibration body and the main body. These intermediaries include elastic members and air cushion members that mediate the transmission of vibration forces, effectively preventing vibrations from being transmitted to the main body while maintaining the necessary mechanical connections.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If multiple vibroisolating bodies with link structures are installed, then vibration isolation is improved, but the structural complexity increases

Engineering Contradiction:
Improvevibration isolation efficiencyVSAvoidlink structure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

Each vibroisolating body is designed as a multi-functional component that simultaneously performs multiple functions: it provides elastic isolation through elastic members, pneumatic isolation through air cushion members, mechanical connection through link structures, and vibration damping. This universality allows the system to achieve comprehensive vibration isolation without requiring separate specialized components for each function, thereby reducing overall structural complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
