A modular assembly arrangement featuring a base plate with holders to fixate batteries and a cover plate with electrical contacts for series connection, along with attachments for easy interlocking, allowing for quick and robust assembly of rechargeable batteries into a battery module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rechargeable batteries are collected in a box and bolted to partition walls, then the batteries are securely fixed, but the assembly process becomes cumbersome and work-intensive
Solution Approach 1:
The battery module is divided into a base plate, cover plate, and attachment components. The base plate contains holders that receive battery bottoms, while the cover plate contains electrical contacts that engage with battery terminals. This segmentation allows for simplified assembly where batteries are simply placed between the plates and secured with attachments, eliminating the need for complex partition walls and multiple bolting operations.
2Reliability
If separate electrical connections are provided for interconnecting batteries, then electrical connectivity is achieved, but the assembly process becomes more complex and time-consuming
Solution Approach 1:
The electrical connection function is merged into the cover plate structure. The cover plate contains electrical contacts that automatically engage with the battery terminals when the cover plate is positioned on top of the batteries. This integration eliminates the need for separate electrical connection steps, as the act of securing the cover plate simultaneously establishes electrical connectivity between all batteries in series.
3Stability of the object's composition
If batteries are fixed to partition walls in a box, then structural stability is achieved, but the voltage and geometrical design are limited to specific applications
Solution Approach 1:
The base plate and cover plate are designed as universal components that can accommodate different numbers and arrangements of batteries. The holders in the base plate and electrical contacts in the cover plate can be configured to support various battery configurations (series, parallel, or combinations). This universal design allows the same basic structure to be adapted for different voltage requirements and geometrical arrangements, making it suitable for multiple lift-truck applications rather than being limited to a single specific design.
