Braiding Apparatus Two-Point Interweaving Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional braiding apparatuses produce a crowdedly-interwoven pattern that limits heat conduction and efficiency in heat dissipation due to excessive crossing points and reduced contact surface between carrier strands and the core strand.
Innovation Solution
A braiding apparatus with a track assembly that defines two braiding routes intersecting at 180 degrees, allowing strand carriers to shuttle and interweave, creating a braided layer with two crossing points per convolution, increasing the contact surface and reducing interstices.

Engineering Contradiction Analysis
1Productivity
If a circular arrangement of rotating discs is used to guide strand carriers, then continuous braiding operation is achieved, but too many crossing points are formed reducing heat conduction efficiency
Solution Approach 1:
The circular arrangement of rotating discs is segmented into two separate braiding routes (first and second routes) with different numbers of discs. This segmentation allows control over the number of crossing points while maintaining continuous operation, directly addressing the heat conduction issue by reducing excessive interstices.
Solution Approach 2:
Different regions of the braiding apparatus are assigned different functions: the first braiding route uses an odd number of discs while the second route uses an even number, creating local variations in crossing point distribution. This local differentiation optimizes heat conduction in specific areas while maintaining overall productivity.
2Shape
If multiple rotating discs are arranged in a circle to carry strand carriers, then braided layer formation is achieved, but contact surface between carrier strands and core strand is reduced
Solution Approach 1:
The design transitions from a single circular arrangement to a two-route three-dimensional configuration where carriers traverse both first and second braiding routes. This dimensional expansion increases the contact surface area between carrier strands and core strand while still forming the required braided layer structure.
3Productivity
If carrier strands are crowdedly interwoven to form braided layer, then complete rope production is achieved, but heat dissipation efficiency is limited
Solution Approach 1:
The invention changes the parameters of the braiding process by using different numbers of rotating discs (odd vs. even) in the two routes, which alters the crossing point density and interstice distribution. This parameter optimization maintains rope production while improving heat dissipation efficiency through better thermal contact.

AI summary
A braiding apparatus includes a platform, a base plate, a core unit, a transmission unit, a track assembly, and strand carriers. The track assembly is divided into two braiding track groups each provided with transmission discs. The transmission discs of both braiding track groups are sequentially connected to define two braiding routes. The strand carriers shuttle on both braiding routes respectively and incessantly. Two intersection points are defined when the two braiding routes intersect. Accordingly, carrier strands fed by the strand carriers are wound around a core strand fed by the core unit while shuttling incessantly and are interwoven with each other while passing through the two intersection points during the incessant shuttling motion, thereby wrapping a multi-convolutional braided layer around the core strand to complete a rope. Each convolution of the braided layer has two crossing points, which increases the practicability of the rope.
