Fuel Unit Lift Adapter for Precise EV Battery Pallet Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for replacing electric vehicle (EV) batteries or fuel cells are inefficient, as they require the use of forklifts to lift and position fuel unit pallets, which can be difficult to control, leading to potential damage and misalignment with lift tables.
Innovation Solution
The development of fuel unit pallet-lifting adapters that include elongated connecting bars and straps, allowing for controlled lifting and positioning of EV batteries and their pallets onto lift tables using a vehicle lift, ensuring precise alignment and safe transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a forklift is used to lift and position the fuel unit pallet, then the lifting capability is sufficient, but the control precision and alignment accuracy deteriorate
Solution Approach 1:
The patent introduces a forklift adapter as an intermediary device between the forklift and the fuel unit pallet. This adapter includes a pallet engagement portion that securely attaches to the pallet and a lift engagement portion that interfaces with the forklift forks. The adapter acts as a mediator that transfers the lifting force from the forklift while providing controlled positioning and alignment features, thereby maintaining lifting capability while improving alignment accuracy and control precision.
Solution Approach 2:
The lifting system is segmented into distinct functional components: the forklift adapter with separate pallet engagement and lift engagement portions, and the fuel unit pallet itself. This segmentation allows each component to be optimized for its specific function - the adapter for precise positioning and alignment, and the pallet for secure cargo holding - thereby resolving the contradiction between lifting capability and alignment accuracy.
2Force
If a forklift is used to move the fuel unit pallet, then the lifting capacity is adequate, but the ease of operation and control deteriorate
Solution Approach 1:
The forklift adapter serves as an intermediary that simplifies operation by providing a standardized interface between the forklift and various fuel unit pallets. The adapter includes alignment features and engagement mechanisms that automatically guide proper positioning, reducing the skill level and effort required by operators while maintaining adequate lifting capacity.
3Device complexity
If conventional lifting methods are used without adapters, then the device complexity is low, but the reliability and safety of the transfer process deteriorate
Solution Approach 1:
The forklift adapter incorporates protective and stabilizing features before the actual lifting operation begins. These include alignment guides that prevent misalignment, secure engagement mechanisms that ensure proper attachment, and structural reinforcement that distributes loads safely. These beforehand preparations cushion against potential failures and improve transfer safety without excessive complexity.
4Measurement precision
If precise alignment is achieved during lifting, then the positioning accuracy improves, but the device complexity increases
Solution Approach 1:
The forklift adapter employs asymmetric design features such as non-symmetric alignment guides and positioned engagement points that naturally guide the pallet into the correct orientation and position during lifting. This asymmetric configuration provides inherent alignment without requiring complex adjustment mechanisms, thereby achieving positioning accuracy with minimal added complexity.

AI summary
A fuel unit assembly-lifting adapter is configured to couple with a vehicle lift in order to engage, raise, and lower a fuel unit assembly. The fuel unit assembly-lifting adapter includes an elongated fuel unit assembly-engaging portion terminating into a first end and a second end and a lift-engaging portion comprising a first member extending from the first end of the fuel unit assembly-engaging portion, and a second member extending from the second end of the fuel unit assembly-engaging portion, wherein the first member and the second member are configured to detachably engage a vehicle lift such that the fuel unit assembly-engaging portion may raise and lower the fuel unit assembly in response to movement of the vehicle lift.
