Dual-End Actuating Shaft Vibration Generator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vibration generators suffer from inefficient vibration distribution due to a single actuating shaft connection, leading to deformation, economic losses, and risk of breakage, as they can only transmit vibrations in one direction and concentrate load on fluid supply tubes.
Innovation Solution
A vibration generator design with an actuating shaft protruding from both ends of the housing, allowing simultaneous vibration application to multiple external objects, and a movable fluid supply tube to distribute fluid pressure equally, reducing load concentration and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the actuating shaft is connected to external objects at only one end, then the structure is simple, but the vibration generator can transmit vibrations in only one direction and the actuating shaft is subjected to bending moment causing deformation
Solution Approach 1:
The actuating shaft is segmented into two protruding ends (first and second ends) that extend from opposite sides of the housing. Each end can independently connect to external objects, allowing the single shaft to transmit vibrations in multiple directions simultaneously, thus resolving the contradiction between structural simplicity and vibration transmission versatility
2Device complexity
If the actuating shaft is connected to external objects at only one end, then the structure is simple, but the actuating shaft is subjected to bending moment causing deformation and shortened service life
Solution Approach 1:
The dual-end configuration of the actuating shaft acts as a counterbalancing structure. When both ends are connected to external objects, the gravitational and operational loads are distributed across both connection points rather than concentrated at a single point, eliminating the bending moment that causes deformation and extending the service life of the shaft
3Ease of manufacture
If the fluid supply tube is connected perpendicular to the housing movement direction, then the connection is straightforward, but the load during longitudinal movement concentrates on the connected portion causing breakage risk
Solution Approach 1:
The fluid supply tube connection is designed to move dynamically with the housing during longitudinal movement. By allowing the connection point to follow the housing's motion trajectory, the relative stress and load concentration at the connection point are eliminated, preventing breakage while maintaining ease of manufacture
4Device complexity
If only one end of the actuating shaft protrudes, then the structure is simple, but vibrations are output in only one direction requiring multiple vibration generators for different work environments
Solution Approach 1:
The actuating shaft is designed with universal multi-functionality by having both ends protrude from the housing. This allows a single vibration generator to perform multiple functions: transmitting vibrations in opposite directions simultaneously, connecting to different external objects at each end, and adapting to various work environments without requiring additional vibration generators, thus improving productivity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design doubles vibration output, minimizes actuating shaft deformation, and prevents fluid supply tube breakage by distributing load evenly, thus improving vibration efficiency and extending the device's service life.
Implementation Method 1
When fluid such as compressed air is supplied to the inside of the housing from the outside, the housing collides with an actuating shaft while repeatedly moving in a reciprocating manner due to the structure of an internal fluid flow path

AI summary
The present invention relates to a vibration generator, an more particularly to a technology in which an actuating shaft protrudes from the opposite ends of a housing such that vibrations generated from the actuating shaft are alternately output in opposite directions of the housing so as to improve vibration efficiency and such that a single vibration generator simultaneously applies the vibrations to a plurality of external objects so as to additionally enhance an economic effect. Furthermore, the present invention relates to a technology in which an actuating shaft protrudes from the opposite ends of a housing, thereby enabling stable installation. In addition, the present invention relates to a technology in which a fluid supply tube is configured to be movable in the axial direction of an actuating shaft so as to prevent breakage of the connected portion of the fluid supply tube, which might otherwise occur during the operation of the vibration generator.
