Automated Hatch Press-Fit Assembly for Modular Battery Stacks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual assembly of modular battery cell stack assemblies is inefficient and causes operator fatigue due to the need for repeated manual applications of force to secure frame members.
Innovation Solution
An apparatus with a surface member, hatch member, position sensor, actuator, and controller that automates the assembly process by moving the work piece receiving member to press-fit components together when the hatch member is closed, allowing for efficient and controlled assembly of press-fit modular work pieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual assembly operations are used to align and press-fit frame members, then the assembly process can be performed with simple equipment, but the productivity is low and operator fatigue increases due to repeated manual applications of force
Solution Approach 1:
The system uses a position sensor to automatically detect when the hatch member is in the closed position, and the controller automatically triggers the actuator to apply the press-fit force. This self-service automation eliminates the need for manual operation while maintaining a relatively simple apparatus structure.
Solution Approach 2:
The patent replaces manual mechanical operations with an automated system consisting of an actuator, position sensor, and controller. The actuator automatically applies the press-fit force that previously required manual operation, substituting human mechanical action with an automated mechanical system.
2Manufacturing precision
If automated press-fit assembly is implemented using an actuator and controller, then productivity and precision are improved, but the device complexity increases due to additional components like position sensors and control systems
Solution Approach 1:
The position sensor provides feedback to the controller about the hatch member's position. When the sensor detects that the hatch member is closed, it triggers the controller to activate the actuator. This feedback mechanism ensures precise timing of the press-fit operation without requiring complex control logic.
Solution Approach 2:
The position sensor continuously monitors the hatch member position in advance, ready to trigger the actuator as soon as the correct position is detected. This preliminary monitoring ensures that the press-fit force is applied at the precise moment when components are properly aligned, improving manufacturing precision.

AI summary
An apparatus for assembling a press-fit modular work piece is described that includes a surface member having a central opening. A hatch member is disposed on one side of the surface member, and is moveable between a first position where it does not cover the opening and a second position covering the opening. A work piece receiving member is disposed proximate the other side of the surface member across from the central opening for receiving components of the press-fit modular work piece. An actuator moves the work piece receiving member toward the opening so components of the work piece press against the hatch member when the hatch member is moved into the second position. The actuator moves the work piece receiving member to a position to receive components of the work piece when the hatch member is in the first position.
