Shared DC Bus Conveyance Path for Regenerative Power Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conveyance systems face challenges in efficiently processing regenerative power due to the need for multiple energy storage assemblies at undefined deceleration points, leading to increased system size and cost.
Innovation Solution
A conveyance system with a common direct-current bus connecting multiple conveyance path units, allowing regenerative power supply across units where the carrier has not entered, thereby managing power distribution and consumption efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If energy storage assemblies are installed at all points where the carrier may decelerate, then regenerative power can be appropriately processed, but the system size and production cost increase
Solution Approach 1:
The patent combines multiple energy storage assemblies into a single shared energy storage assembly that serves the entire conveyance path. Instead of having separate energy storage assemblies at each deceleration point, one assembly is strategically positioned to collect regenerative power from multiple carriers decelerating at different locations along the path, thereby reducing the total number of assemblies while maintaining regenerative power processing capability
Solution Approach 2:
The single energy storage assembly performs multiple functions: it collects regenerative power from carriers decelerating at various points along the conveyance path, stores energy for multiple carriers, and supplies power to multiple drive units. This multi-functional approach replaces the conventional single-function approach where each energy storage assembly serves only one specific deceleration point
