3D Vibrating Plate Layout for Low-Loss Multi-Directional Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vibrating apparatuses suffer from energy loss and restricted vibration areas due to the arrangement of actuators, which limits the distance between the plate and the support, leading to inefficient vibration distribution.
Innovation Solution
A three-dimensional vibrating apparatus with a base unit, loading plate unit, and actuating units that are coplanarly arranged and connected via resilient members, allowing independent control of movable parts for various vibratory modes, including opposite and different directional movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the plate is fixed to the support with actuators arranged in three-dimensional directions, then the objects can be moved and scattered, but some vibrating energy is lost and the plate area is restricted
Solution Approach 1:
The patent transitions from three-dimensional actuator arrangement to a coplanar (two-dimensional) arrangement of actuating units. The actuating units are disposed on the same plane between the base plate and loading plate unit, with movable parts that move upwardly and downwardly relative to the base plate. This dimensional change allows for more efficient energy transmission while enabling a larger loading plate area.
Solution Approach 2:
The patent introduces resilient members as intermediary elements that interconnect the movable parts of the actuating units with the loading plate unit. These resilient members flexibly transmit vibrating energy from the actuators to the loading plate, reducing energy loss while allowing for larger plate areas without compromising vibration effectiveness.
2Area of stationary object
If the plate area is increased, then more objects can be processed, but the distance between portions of the plate and the support increases, reducing vibration effectiveness
Solution Approach 1:
The patent divides the vibration transmission function into multiple coplanarly arranged actuating units, each with its own movable part and resilient member. This segmentation allows the system to cover a larger plate area while maintaining effective vibration transmission at each location, as each actuating unit independently transmits energy to its corresponding region of the loading plate.
Solution Approach 2:
The resilient members serve as flexible intermediaries that efficiently transmit vibrating energy over larger distances. By using these resilient connections between the coplanar actuators and the loading plate, the system maintains vibration effectiveness even as the loading plate area increases, solving the problem of reduced vibration at distant portions.
3Adaptability or versatility
If actuators are arranged in three-dimensional directions, then objects can be moved, but the structure is complex and energy loss occurs
Solution Approach 1:
The patent achieves multiple vibratory modes (at least seven different modes including opposite directions) through coplanar actuating units with independent frequency and amplitude control. By arranging actuators on the same plane rather than in three-dimensional space, the system maintains versatility while simplifying the structural arrangement and reducing complexity.
Solution Approach 2:
The patent employs resilient members that provide flexible, dynamic connections between the coplanar actuators and the loading plate. This dynamic arrangement allows the system to achieve complex vibratory patterns and multiple modes of vibration without requiring complex three-dimensional actuator positioning, as the resilient members adapt to transmit energy in various directions.

AI summary
A three-dimensional vibrating apparatus includes a base plate and a loading plate unit. A loading surface of the loading plate unit is to be loaded with objects, and has a periphery. Three actuating units are disposed between the base plate and the loading plate unit. Each actuating unit includes a movable part, and a first resilient member interconnecting the movable part and the loading plate unit. The three actuating units are operable for driving the loading plate unit to move relative to the base plate in seven vibratory modes. In one of the seven vibratory modes, the objects are vibrated to move in a pair of opposite directions, and in each of the remaining six of the seven vibratory modes, the objects are vibrated to move simultaneously in a corresponding one of six different directions.
