Braiding Machine Diverter Channels for Flat Round Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing braiding machines require time-consuming reconfiguration to switch between flat and round braiding, making it impractical to produce threads with alternating sections, which is a limitation in applications like surgery where high-standard stitching is required.
Innovation Solution
A braiding machine with a series of plates arranged in a closed circuit, featuring diverter channels that allow for automatic switching between flat and round braiding configurations within seconds, enabling seamless transitions without stopping the machine and avoiding thread splicing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the machine is stopped and reconfigured to switch between flat and round braiding, then the braiding pattern can be changed, but production time is lost and productivity decreases
Solution Approach 1:
The patent applies the dynamics principle by making the plate circuit configurable and adaptable during operation. The system transitions from a fixed configuration to a dynamic one where plates can be selectively engaged or disengaged from the circuit. This allows the machine to switch between flat braiding (all plates engaged) and round braiding (selected plates disengaged) without stopping, resolving the contradiction between adaptability and productivity
Solution Approach 2:
The patent implements preliminary action by pre-positioning multiple plates with different slot configurations in the circuit before operation begins. The control system can then selectively engage or disengage specific plates based on the desired braiding pattern. This preparation in advance eliminates the need for stopping the machine to reconfigure, thereby maintaining high productivity while enabling pattern switching
2Adaptability or versatility
If the machine structure is simplified for single-pattern production, then manufacturing cost is reduced, but adaptability to produce different braiding patterns is lost
Solution Approach 1:
The patent applies segmentation by dividing the braiding machine into multiple independent plate units, each with specific slot configurations. Instead of a single complex mechanism, the system uses multiple simpler plate segments that can be independently controlled. Each plate can be engaged or disengaged from the circuit, allowing flexible combination to produce different braiding patterns while keeping individual components relatively simple
Solution Approach 2:
The patent implements universality through plates that can serve multiple functions depending on their engagement status. The same physical plate structure can participate in flat braiding when engaged or be excluded for round braiding when disengaged. This multi-functionality allows a single machine structure to produce multiple braiding patterns without requiring separate dedicated mechanisms for each pattern type

AI summary
Braiding machine comprising a series of plates arranged in a continuous manner in a closed circuit, each plate comprising a number of slots that accommodate a number of spindles with a guide; at least one drive means that drives the plates, guide channels where the spindle guides run and at least two diverter channels having two positions: a first position for continuous rotation in one same plate and a second position, for switching plates.
