Board Stack Storage with Battery-Powered Satellite Wagons
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage systems for large stacks of boards in factories require the main wagon to be stationary during the operation of satellite wagons, limiting its ability to perform other tasks and necessitating time-consuming installation and connection procedures for satellite wagon replacement or servicing.
Innovation Solution
The storage system employs battery-powered satellite wagons with independent energy supply, utilizing battery packs on the satellite wagons and a charging station on the main wagon, along with replacement stations for quick battery swaps, allowing satellite wagons to operate independently of the main wagon and enabling simultaneous tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cable reel arrangement is used to supply satellite wagons, then satellite wagons can be powered and moved, but the main wagon must remain stationary during satellite wagon operation, limiting productivity
Solution Approach 1:
The power supply system is segmented into modular battery packs that can be independently replaced on the main wagon, allowing the main wagon to remain mobile while satellite wagons are serviced without stopping the entire system
Solution Approach 2:
The battery packs are designed to be dynamically replaceable during operation, enabling quick swapping of power sources without requiring the main wagon to stop or return to a fixed charging location
2Ease of operation
If cable reel arrangement is used, then satellite wagons can operate, but time-consuming installation and connection procedures are required for satellite wagon replacement or servicing
Solution Approach 1:
Battery packs are pre-charged and prepared in advance on the main wagon, so when a satellite wagon needs servicing, a ready-to-use battery pack is already available for immediate replacement without installation delays
Solution Approach 2:
The battery packs are designed as replaceable units that can be quickly swapped out and replaced, similar to disposable components, eliminating the need for complex reconnection procedures during maintenance
