Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vibratory linear actuators face challenges in size reduction of the stator element while maintaining the integrity of the fastening portion counterpart, often leading to deformation issues when fastened to other components.
Innovation Solution
The vibratory linear actuator incorporates a stator element with a fastening portion featuring a pair of legs and protrusions that face each other, allowing for secure attachment to a fastening portion counterpart, thereby reducing the size of the stator element and preventing deformation of the counterpart.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the stator element is reduced in size, then the overall actuator size is reduced, but the fastening portion counterpart deforms
Solution Approach 1:
The fastening portion is segmented into two functional elements: legs that provide mechanical support and protrusions that provide locking function. This segmentation allows the fastening portion to maintain structural integrity while reducing overall stator element size, as the distributed contact points concentrate stress appropriately without deforming the fastening portion counterpart
Solution Approach 2:
The fastening portion combines different geometric features (legs and protrusions) to create a composite structural solution. The legs provide broad support area while protrusions provide localized locking, creating a composite fastening system that maintains counterpart integrity despite reduced stator element dimensions
2Device complexity
If a conventional fastening portion is used, then the structure is simple, but deformation of the fastening portion counterpart occurs
Solution Approach 1:
The fastening portion is divided into legs for support and protrusions for locking, creating a segmented structure that enhances fastening force stability. The multiple contact points distribute and stabilize the fastening force, preventing counterpart deformation while maintaining reasonable structural complexity
Solution Approach 2:
The protrusions act as intermediary elements that mediate between the fastening portion and the fastening portion counterpart. They provide a localized interface that concentrates fastening force in specific areas, stabilizing the connection and preventing deformation of the counterpart while adding minimal structural complexity
