Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing winding apparatuses for power storage devices face challenges in maintaining consistent and homogeneous material motion due to non-circular core shapes, and the integration of electrical or pneumatic utilities on the rotating head is complex, leading to increased costs and structural complexity.
Innovation Solution
A winding apparatus with a torque motor-driven rotor and support system that allows for orbital motion of the core, enabling uniform material winding and simplified utility connection through a hollow shaft, reducing wear and turbulence, and allowing for pneumatic utilities on board to prevent cable entanglement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If sliding electrical contacts are used to provide utilities on the rotating head, then electrical power and signals can be transmitted, but the structure becomes extremely complex, heavy, expensive and subject to wear
Solution Approach 1:
The patent extracts the utilities (electrical contacts, pneumatic lines) from the rotating head and places them on the stationary support structure. The rotating head becomes a simple mechanical component without embedded utilities, eliminating the complexity and wear issues of sliding contacts while maintaining full automation capability through the orbital motion mechanism
Solution Approach 2:
The patent introduces a hollow shaft as an intermediary structure that allows utilities to pass through the rotating support without being attached to the rotating head. This mediator enables power and signal transmission through the rotating support while keeping the head itself simple and utility-free
2Extent of automation
If utilities are placed on board the rotating head, then automation and control are improved, but cable entanglement and connection breakage occur
Solution Approach 1:
The patent removes all utilities from the rotating head, placing them instead on the stationary support structure. This extraction eliminates the fundamental cause of cable entanglement and connection breakage while preserving automation through the orbital motion of the utility-free head
Solution Approach 2:
The patent replaces the mechanical cable connection system (prone to entanglement and breakage) with a pneumatic utility system that passes through the hollow shaft of the rotating support, providing more reliable connections for automated operation
3Volume of moving object
If a non-circular core is used for winding, then the winding structure is compact, but the motion of input material becomes inconsistent and inhomogeneous
Solution Approach 1:
The patent transforms the static non-circular core into a dynamic system where the support carrying the core performs orbital motion. This dynamic movement compensates for the non-circular geometry, maintaining consistent material feed rate and homogeneous tension throughout the winding process while preserving the compact winding structure
Solution Approach 2:
The patent changes the motion parameters of the support system by introducing orbital motion with specific radius and velocity characteristics. This parameter change compensates for the geometric irregularities of the non-circular core, ensuring consistent material motion and tension during winding
