Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the production of batteries, trays carrying different types of batteries or empty trays often transport to incorrect positions or experience congestion, leading to inefficiencies in the battery assembly system.

A battery assembly system with a stacking platform, assembly apparatus, and return apparatus, including diversion, lifting, and pressurizing mechanisms, to accurately route and store trays, reducing congestion and ensuring timely delivery to correct positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If trays carrying different types of batteries or empty trays are transported through the battery assembly system, then battery production and assembly operations can be performed, but trays may be transported to incorrect positions or fail to reach corresponding positions in a timely manner
Solution Approach 1:
The system employs identification devices to detect tray types and positions, then provides feedback signals to control the circulation line speed and diversion mechanisms. This closed-loop feedback ensures trays are transported to correct positions accurately and timely, resolving the contradiction between positioning precision and transport time.
Solution Approach 2:
The circulation line features variable speed control capabilities, allowing the system to dynamically adjust transport speed based on tray type, position requirements, and system congestion levels. This dynamic adjustment enables both rapid transport when possible and precise positioning when required.
2Productivity
If multiple cache positions are provided for trays through the return apparatus, then the risk of congestion during the return process of trays is reduced, but the device complexity increases
Solution Approach 1:
The return apparatus is segmented into multiple independent cache positions (first cache position, second cache position, etc.) that can operate independently. This segmentation allows parallel processing of different tray types and prevents congestion by distributing trays across multiple storage locations rather than a single bottleneck.
Solution Approach 2:
The return apparatus acts as an intermediary buffer between the assembly apparatus and the stacking platform. By introducing this intermediate storage system with multiple cache positions, the patent decouples the return process from direct congestion points, allowing smoother tray flow despite increased structural complexity.
3Volume of stationary object
If only one stacking platform is provided to store both empty trays and trays carrying battery modules, then the battery assembly system size is reduced, but tray management complexity increases
Solution Approach 1:
The single stacking platform is designed with multi-functionality to serve dual purposes: storing both empty trays and trays carrying battery modules. This universal platform replaces what would traditionally require separate storage areas, reducing overall system footprint while incorporating identification and sorting mechanisms to manage the diversity of tray types.
Solution Approach 2:
The system employs automatic identification devices and control mechanisms that enable the stacking platform to self-manage different tray types without extensive manual intervention. The platform automatically identifies tray types, directs appropriate trays to correct locations, and manages circulation, reducing operational complexity despite the multi-functional requirements.
