Transport Device Backflow Prevention Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conductor wire pieces often collide with downstream walls during transfer, causing them to bounce back and potentially damage the device when the feeding force is strong, leading to backflow issues that result in the wire pieces coming into contact with device parts.
Innovation Solution
A transport device equipped with backflow prevention mechanisms featuring inclined inductive plates and coupling plates on the transport rails, which guide the wire pieces into the rail and prevent backflow by regulating movement, ensuring they stay on the rail even if they attempt to flow backward.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If strong feeding force is applied to transport conductor wire pieces, then transport speed and productivity are improved, but the conductor wire pieces collide with downstream walls and bounce back causing damage
Solution Approach 1:
The patent converts the harmful bouncing back motion into a beneficial guiding action by using inclined inductive plates. When conductor wire pieces collide with the inclined surface, the bounce is redirected toward the center of the rail rather than causing damage, transforming the harmful collision into a useful self-centering mechanism that maintains transport speed while preventing damage
Solution Approach 2:
The patent introduces inductive plates and coupling plates as intermediary elements between the conductor wire pieces and the rail structure. These plates act as mediators that intercept and redirect the bouncing wire pieces, preventing direct collision with downstream walls and protecting the system while allowing strong feeding forces to be applied
2Productivity
If conductor wire pieces are transferred with high force, then feeding efficiency is improved, but backflow occurs causing wire pieces to contact device parts
Solution Approach 1:
The patent segments the backflow prevention function into multiple components: inductive plates that redirect bouncing wire pieces, coupling plates that combine with rail structures, and projecting portions that extend upward. This segmentation allows each component to handle specific aspects of backflow prevention while maintaining high feeding efficiency
Solution Approach 2:
The patent addresses backflow by adding vertical dimension elements (projecting portions extending upward from the rail) to prevent wire pieces from contacting device parts. This dimensional addition creates a three-dimensional containment structure that stops backflow in both horizontal and vertical directions without reducing feeding efficiency
3Ease of operation
If inductive plates are inclined from center to side, then wire pieces are guided into the rail easily, but complex structure is required
Solution Approach 1:
The patent merges multiple functions into the inductive plates and coupling plates: guiding wire pieces into the rail, preventing backflow, and providing structural support. By combining these functions into integrated components rather than separate elements, the patent achieves effective guiding without proportionally increasing overall structural complexity
Solution Approach 2:
The patent uses specific geometric parameters (inclination angles, plate dimensions, positioning) to optimize guiding efficiency. By carefully selecting these parameters, the patent achieves effective wire piece guidance with simple plate structures rather than complex mechanisms, balancing ease of operation with structural simplicity
