Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heavy-duty transport module vehicles require complex coordination and mechanical rigidity for load transport, leading to high operational costs and time-consuming steering coordination, and lack efficient energy independence and compact design.
Innovation Solution
A heavy-duty transport module vehicle with independently drivable axle assemblies on a common carrier, a rotatable load-bearing unit, and a control and communication system for synchronized movement and energy management, allowing for modular, compact, and stable load transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate steering devices are provided for axle assemblies, then steering control is improved, but device complexity increases
Solution Approach 1:
The patent extracts the steering function from separate steering devices and integrates it into the drive units of the axle assemblies. Each drive unit independently controls its axle assembly by varying rotation speed and direction, eliminating the need for separate steering mechanisms while maintaining full steering control capability.
Solution Approach 2:
The drive units are designed to perform multiple functions: both driving (propulsion) and steering (direction control). By controlling the rotation speed and direction of each axle assembly through the drive units, the system achieves both movement and steering without requiring dedicated steering components.
2Stability of the object's composition
If mechanical rigid connection of vehicles is used, then load transport stability is improved, but steering coordination time increases
Solution Approach 1:
The patent segments the steering control into independent units, with each vehicle's drive units autonomously controlling their respective axle assemblies. This eliminates the need for centralized steering coordination while maintaining stable load transport through independent synchronized control of each module's drive units.
Solution Approach 2:
Each vehicle module independently manages its own steering and drive functions through its control device and drive units. The system performs self-service by autonomously coordinating movement without external intervention, reducing steering coordination time while maintaining load stability through independent control.
3Productivity
If external command center remote control is implemented, then operational cost is reduced, but control complexity increases
Solution Approach 1:
The vehicle modules autonomously control their own drive and steering functions through onboard control devices that communicate with each other. This self-service capability eliminates the need for complex external command center infrastructure while reducing operational costs through automated independent operation.
Solution Approach 2:
The communication devices enable bidirectional data exchange between control devices of different vehicle modules, creating a feedback system where each module shares status and coordination information. This distributed feedback mechanism simplifies control complexity by eliminating centralized command infrastructure while maintaining coordinated operation.
