Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current braiding machines operate at a constant speed, which limits productivity due to the need to maintain a maximum load and prevent overload, rather than optimizing for increased productivity.
Innovation Solution
A braiding machine with multiple carriers around a common center, where the drive system controls the speed to maintain a nearly constant centrifugal force, allowing for increased speed as the mass of the carriers decreases, thereby enhancing productivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the braiding machine operates at constant maximum speed, then productivity is maximized, but the machine becomes overloaded when carriers are full
Solution Approach 1:
The patent applies dynamics by transitioning from constant speed operation to variable speed operation. The control device dynamically adjusts the rotational speed of the braiding-material carriers based on real-time centrifugal force measurements. When carriers are full (higher mass), the speed is reduced to maintain constant centrifugal force; when carriers are empty (lower mass), the speed is increased. This dynamic adaptation resolves the contradiction between maintaining high productivity and preventing machine overload.
Solution Approach 2:
The patent changes the operational parameter from constant speed to constant centrifugal force. The control device continuously monitors the centrifugal force acting on the carriers and adjusts the rotational speed accordingly to maintain a predetermined constant centrifugal force value. This parameter change allows the system to operate optimally across varying carrier masses, preventing overload while maximizing productivity throughout the braiding process.
2Reliability
If the machine speed is reduced to prevent overload, then machine reliability is improved, but productivity decreases
Solution Approach 1:
The patent implements feedback control by using sensors to continuously measure the actual centrifugal force acting on the braiding-material carriers and feeding this information back to the control device. The control device compares the measured centrifugal force with the predetermined target value and adjusts the rotational speed accordingly. This closed-loop feedback system ensures the machine operates reliably within safe centrifugal force limits while maximizing productivity by allowing higher speeds when conditions permit.
