Solution Overview

Problem

Existing vibration conveyors face issues with vibration decoupling from the foundation, leading to noise and heating problems, especially as they become larger and more powerful, and their complex structural designs make it difficult to transfer the spring suspension to other conveyors.

Innovation Solution

A suspension set comprising multiple suspension units with carriers, springs, and spring connection parts, where the springs are arranged to reduce vibration transmission to the foundation and allow for simpler assembly by attaching carriers to the sides of the oscillator and counterweight, rather than through them, enabling easier adaptation to different designs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If rubber buffers are used to support the base frame, then vibration isolation is achieved, but noise generation and heating occur leading to inaccuracies

Engineering Contradiction:
Improvevibration isolationVSAvoidnoise and heating
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent changes the material parameter from rubber buffers to spring elements, fundamentally altering the vibration isolation mechanism. Springs provide elastic support without the friction and heat generation inherent in rubber buffers, thereby eliminating noise and heating while maintaining vibration isolation effectiveness.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces the rubber buffer mechanical system with a spring-based mechanical system. This substitution changes the fundamental mechanism of vibration isolation from viscoelastic damping to elastic deformation, achieving the same vibration isolation function without the harmful thermal and acoustic side effects of rubber buffers.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If spring suspension is used to reduce vibration transmission, then vibration decoupling improves, but structural complexity increases

Engineering Contradiction:
Improvevibration decouplingVSAvoidstructural complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the vibration conveyor system into distinct functional modules: the oscillator assembly, the base frame, and the spring suspension elements. This segmentation allows the spring suspension to be implemented as a modular component that can be independently designed, installed, and maintained, reducing overall structural complexity while achieving effective vibration decoupling.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spring elements serve as intermediary components between the oscillator and the base frame. These springs act as a mediator that provides vibration decoupling without requiring complex integration into the oscillator or base frame structures. The intermediary springs can be simply attached to both components, achieving vibration isolation with minimal structural modification.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If vertical supports extending through the interior are used, then vibration isolation is achieved, but assembly complexity and difficulty increase

Engineering Contradiction:
Improvevibration isolationVSAvoidassembly simplicity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent extracts the spring suspension elements from the interior of the oscillator and base frame, positioning them externally as separate components. This extraction eliminates the need for complex internal routing and integration of support structures, allowing for straightforward assembly where springs are simply attached to the exterior surfaces of the oscillator and base frame, significantly simplifying manufacturing and assembly.

Inventive Principle:
Principle #2Taking out (Extraction)

4Reliability

If complex structural designs are used, then vibration control is improved, but adaptability to other conveyor designs decreases

Engineering Contradiction:
Improvevibration controlVSAvoiddesign adaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent designs the spring suspension elements as universal components that can be applied to various conveyor designs. The springs serve multiple functions: vibration isolation, structural support, and shock absorption. This universal spring-based approach can be adapted to different oscillator and base frame configurations without requiring design-specific customization, thereby enhancing adaptability while maintaining effective vibration control.

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