Spool Flipper Mechanism for Torque-Free Wire Unwinding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for unwinding wire from a spool introduce torque into the wire, posing safety risks and potentially damaging the spool, as they require manual rotation from a vertical to a horizontal position, which can be hazardous and cause spool damage.
Innovation Solution
A device with a rotating holder that securely clamps the spool in a vertical position, allowing safe rotation to a horizontal position for unwinding without torque, featuring a brake mechanism to control unwinding and a mechanical or hydraulic mechanism for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the spool is manually rotated from vertical to horizontal position using a forklift, then the spool can be positioned for unwinding, but safety risks increase and spool damage may occur
Solution Approach 1:
The patent replaces the manual forklift operation with an automated mechanical system consisting of a rotating platform and holder mechanism. The platform automatically rotates the spool from vertical to horizontal position and positions it on the holder, eliminating manual intervention and associated safety risks.
Solution Approach 2:
The spool positioning system is self-operating through the automated rotating platform and holder mechanism. The system automatically completes the positioning task without requiring external manual操作, making the process safer and more reliable.
2Productivity
If the spool is manually rotated from vertical to horizontal position, then unwinding can proceed, but the spool may be damaged
Solution Approach 1:
The patent replaces manual forklift rotation with a controlled automated rotating platform system. This system provides smooth, controlled rotation that prevents sudden movements and impacts, protecting the spool from damage while enabling the unwinding process.
Solution Approach 2:
The automated system provides controlled, gradual rotation and positioning that prevents sudden impacts or shocks to the spool. The mechanism ensures the spool is gently positioned on the holder, preventing damage before the unwinding process begins.
3Productivity
If a turntable is used to rotate the spool, then wire can be unwound, but torque is introduced into the wire
Solution Approach 1:
Instead of rotating the spool horizontally on a turntable, the patent inverts the approach by using a vertical holder that receives the spool in horizontal position. The wire unwinds vertically downward under gravity, eliminating the torque that would be introduced by horizontal rotation on a turntable.
Solution Approach 2:
The patent replaces the horizontal turntable rotation mechanism with a vertical holder system where the spool is positioned horizontally and the wire unwinds vertically. This substitution eliminates the torque-generating rotation while maintaining the unwinding function.
4Object-generated harmful factors
If the spool is pushed over to horizontal position, then unwinding without torque is achieved, but the spool becomes unstable and may roll
Solution Approach 1:
The patent introduces a holder as an intermediary device between the spool and the ground/surface. The holder securely supports the spool in horizontal position, preventing it from rolling or becoming unstable, while allowing the wire to unwind vertically without introducing torque.
Solution Approach 2:
Instead of trying to stabilize a rolled-over spool, the patent inverts the approach by using a vertical holder to support the horizontally-positioned spool. This inversion provides inherent stability through the holder structure while maintaining the torque-free unwinding configuration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables safe and efficient unwinding of wire without introducing torque, preventing accidents and spool damage, while ensuring controlled unwinding and easy repositioning for storage.
Implementation Method 1
The brake may be released to enable unwinding and then reactivated to prevent inadvertent unwinding when the process is complete.
