Modular Carrier Vehicle with Detachable Rear Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric pallet truck vehicles are difficult to assemble, require large space for packaging and transportation, and are cumbersome due to their fully assembled configuration, making them inefficient and costly to manufacture and ship.
Innovation Solution
A modular design for the electric pallet truck vehicle, where the rear frame is easily attachable and detachable from the front frame, allowing for compact disassembly and separate transportation, with innovative features such as a pluggable battery component and a microswitch with adjustable stroke for improved assembly efficiency and load handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle is fully assembled during manufacturing, then the vehicle structure is complete and functional, but the assembly process becomes difficult, build rate slows down, and packaging/storage/transportation space requirements increase
Solution Approach 1:
The vehicle is divided into separate modular components (front frame assembly and rear frame assembly) that are manufactured and tested independently, then connected through detachable linkages. This segmentation enables parallel production of multiple components, significantly increasing assembly build rate while maintaining complete vehicle functionality through the detachable connection system.
2Ease of operation
If the vehicle is fully assembled during manufacturing, then the vehicle is ready for use, but the packaging, storage and shipping space requirements increase
Solution Approach 1:
By segmenting the vehicle into separable modules with detachable linkages, each module can be packaged in a compact state during transportation. The modules are designed to interconnect through standardized attachment mechanisms, allowing the vehicle to be reassembled at the destination without requiring large packaging space for the complete assembled vehicle.
3Reliability
If the vehicle is fully assembled, then the vehicle is complete, but it cannot have independent portions easily detached after assembly
Solution Approach 1:
The linkages connecting the front and rear frame assemblies are designed with detachable features that allow the connection state to change from fixed to separable. This dynamic connection system enables the vehicle to maintain structural integrity during operation while allowing easy detachment and reconfiguration when needed, providing adaptability without compromising vehicle completeness.
4Volume of stationary object
If the vehicle is disassembled for transport, then the packaging and transportation space is reduced, but the assembly process becomes more complex
Solution Approach 1:
The vehicle is segmented into standardized modules with uniform detachable linkages that simplify the disassembly and reassembly process. Each module has clearly defined connection interfaces, reducing assembly complexity despite the disassembled transport configuration. The modular design allows for straightforward reconstruction of the complete vehicle at the destination.

AI summary
A carrier vehicle includes a front frame and a rear frame conveniently attachable to and detachable from the front frame. The front frame includes a frame body, at least one battery structure installed along an inner front side wall of the frame body and a connecting rod wheel component at a transverse bottom of the frame body. The rear frame comprises an operating handle, a handle joint base, a hydraulic component having an oil cylinder, a bearing component and a driving assembly. A bottom end of the operating handle is rotatably connected to the handle joint base, which includes a joint fixing base and a microswitch. The bearing component includes a bearing bridge having bridge lugs detachably connected to ends thereof, and a middle part sleeved on the oil cylinder. The front frame and rear frame are transportable in a separated compact configuration, with later simple and fast assembly.
