Bent Plate Spring Trough for Bidirectional Workpiece Reciprocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration generating apparatuses, such as those in JP-A-6-292862, face difficulties in moving parts in both directions due to the inclined plate springs, making it hard to reciprocate parts effectively.
Innovation Solution
A vibration generating apparatus with a trough supported by two plate springs placed along the movement directions of the workpiece, where the plate springs have bent portions projecting in the direction of movement, allowing for elastic deformation and efficient vibration of the trough to move the workpiece in both directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If plate springs are inclined to facilitate movement in one direction, then parts can move smoothly in the predetermined direction, but it becomes difficult to move parts in the opposite direction and reciprocation is hindered
Solution Approach 1:
The plate springs are designed with asymmetric bent portions that project in the movement direction, creating different elastic characteristics for forward and backward motion. This asymmetric geometry allows the springs to provide facilitating force in the predetermined direction while still permitting controlled reciprocation in the opposite direction, resolving the contradiction between ease of one-directional movement and bidirectional adaptability
2Productivity
If plate springs are inclined to enable easy movement of parts, then parts can be transported efficiently, but the structure becomes unsuitable for reciprocating motion in both directions
Solution Approach 1:
The plate springs incorporate bent portions that dynamically adapt their elastic deformation characteristics based on the direction of motion. During forward motion, the bent portions facilitate efficient transport, while during backward motion, they allow controlled reciprocation. This dynamic adaptation enables the system to maintain high productivity in the primary direction while gaining bidirectional capability
