Collapsible Service Table for EV Battery Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current service tables for transporting battery packs in motor vehicles are cumbersome, occupying significant space and posing safety risks due to the weight and size of the battery packs, which complicates service operations in repair shops.
Innovation Solution
A service table with a collapsible design featuring four frame members, hinges, and wheels that can pivot and adjust to accommodate the battery pack, allowing for a wider configuration for transport and a narrower configuration for storage, optimizing space usage in service departments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cart is used to transport the battery pack, then the battery pack can be moved safely, but the cart occupies considerable surface area within the service department
Solution Approach 1:
The service table employs a collapsible frame structure with movable panels that can transition between an expanded configuration for transporting battery packs and a collapsed configuration for space-efficient storage. This dynamic transformation allows the same device to fulfill both transport functionality and space conservation requirements.
Solution Approach 2:
The service table is divided into multiple separable panels or sections that can be folded or collapsed relative to each other. This segmentation enables the structure to reduce its footprint when not in use while maintaining structural integrity during battery pack transport operations.
2Strength
If the cart is sized to support the battery pack, then the battery pack can be transported, but storing the cart when not in use occupies surface area that could be used for another vehicle
Solution Approach 1:
The service table employs a collapsible frame structure with movable panels that can transition between an expanded configuration for transporting battery packs and a collapsed configuration for space-efficient storage. This dynamic transformation allows the same device to fulfill both transport functionality and space conservation requirements.
Solution Approach 2:
The collapsible design allows panels and structural elements to nest within each other during the collapsed state, similar to nested dolls, maximizing space efficiency while maintaining full support capacity when expanded.
3Reliability
If the service table is in the service configuration, then the battery pack can be transported safely, but the width is larger occupying more space
Solution Approach 1:
The service table employs a collapsible frame structure with movable panels that can transition between an expanded configuration for transporting battery packs and a collapsed configuration for space-efficient storage. This dynamic transformation allows the same device to fulfill both transport functionality and space conservation requirements.

AI summary
A service table for transporting a battery pack comprises four frame members arranged end-to-end in a circuit, four hinges between adjacent frame members, and wheels. The service table further comprises a support bed mounted to at least one of the frame members and configured to support the battery pack. At least one hinge lock is disposed between adjacent frame members and arranged to be rigidly fixed to both of the adjacent frame members in a locked configuration and arranged to be decoupled from at least one of the adjacent frame members in an unlocked configuration. The frame members are arranged in a service configuration having a first width when the hinge lock is arranged in the locked configuration for transporting the battery pack thereon and in a storage configuration having a second width, less than the first width, when the hinge lock is arranged in the unlocked configuration.
