Battery Cell Carrier With Electromagnetic Rail Coupling and Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a stable and efficient carrier system to transport battery cells during the manufacturing process, especially for lithium secondary batteries, which requires precise handling and movement without restrictions on distance due to the absence of a separate driving unit or electricity supply.
Innovation Solution
A carrier system with a base assembly, seating plate, pressurizing and fixing portion, and elastic members that utilize electromagnetic coupling for movement along a transfer rail, allowing independent control and movement without a separate driving unit or electricity supply, featuring a pressurizing and fixing mechanism to secure the battery cell during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate driving unit and electricity supply are used for the carrier, then the carrier can be controlled and moved, but the movement distance is restricted and the device complexity increases
Solution Approach 1:
The patent replaces the traditional mechanical driving system (motors, cables, power supplies) with an electromagnetic coupling system. The base assembly includes a magnetic unit that couples with a driving portion on the transfer rail, enabling the carrier to be moved along the rail through electromagnetic interaction without any mechanical connection or electricity supply to the carrier itself.
Solution Approach 2:
The patent introduces an intermediary electromagnetic field as the mediator between the carrier and the transfer rail. The magnetic unit on the base assembly and the driving portion on the transfer rail interact through this electromagnetic field, allowing force transmission without direct mechanical contact or electrical connection, thus enabling unrestricted movement.
2Adaptability or versatility
If a separate driving unit is installed on the carrier, then the carrier can move independently, but the movement distance is restricted due to cable length limitations
Solution Approach 1:
The patent eliminates the mechanical cable connection by using electromagnetic coupling. The magnetic unit on the base assembly interacts with the driving portion on the transfer rail through an electromagnetic field, allowing the carrier to move independently without any physical connection that would limit its range of motion.
3Length of moving object
If electromagnetic coupling is used for carrier movement, then independent control and unrestricted movement are achieved, but the base assembly structure becomes more complex
Solution Approach 1:
The patent divides the carrier into functional modules: the base assembly containing the magnetic unit, the seating plate for holding the battery cell, and the pressurizing and fixing portion. This segmentation allows the electromagnetic coupling mechanism to be isolated to the base assembly while keeping other components simple.
4Reliability
If a pressurizing and fixing mechanism is added to secure the battery cell, then the battery cell is protected during transport, but the device complexity increases
Solution Approach 1:
The patent merges the pressurizing and fixing functions into a single integrated portion that works together with the elastic member. The pressurizing and fixing portion includes pressurizing members that contact the battery cell and a connection member that links to the elastic member, combining multiple functions into one compact structure.
Solution Approach 2:
The elastic member automatically provides the necessary pressurizing force to secure the battery cell without requiring external control or additional actuators. The elastic restoring force self-regulates to maintain proper fixation throughout the transport process.

AI summary
A carrier includes a base assembly movably coupled to a transfer rail, a seating plate disposed above the base assembly and having a battery cell seated on an upper surface thereof, a pressurizing and fixing portion for fixing the battery cell to the seating plate by pressurizing the battery cell, and an elastic member for pressurizing the pressurizing and fixing portion toward the seating plate side, wherein the pressurizing and fixing portion is coupled to the base assembly to move in a first direction, which is a horizontal direction, and a second direction, which is a vertical direction.
