Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the power supply system is directly arranged on the frame of the tractor, then the installation space is utilized, but the heat dissipation is insufficient and safety is compromised
Solution Approach 1:
The power supply system is segmented into modular battery packs that can be independently installed in the trailer. This segmentation allows for optimized heat dissipation pathways while maximizing space utilization, as each module can be positioned to facilitate airflow and thermal management.
Solution Approach 2:
The battery installation is moved from the traditional horizontal arrangement on the tractor frame to a vertical arrangement in the trailer. This dimensional change exploits the vertical space in the trailer, improving heat dissipation through enhanced airflow paths from top to bottom while maximizing the use of available installation space.
2Quantity of substance
If a large number of batteries are arranged on the body of the tractor, then the battery configuration capacity is increased, but the weight of the full vehicle increases and power performance is affected
Solution Approach 1:
The battery system is extracted from the tractor body and relocated to the trailer. This separation allows the tractor to maintain its original weight and power performance characteristics, while the trailer provides the additional battery capacity needed for extended operation. The trailer effectively becomes an independent power supply module.
3Device complexity
If the battery installation positions are highly concentrated, then the overall structure is compact, but the cooling air duct is limited and temperature rise is rapid
Solution Approach 1:
The battery installation positions are distributed throughout the trailer volume rather than concentrated in one location. This distribution creates multiple local heat dissipation zones, allowing cooling air to flow through different pathways and preventing rapid temperature rise in any single area while maintaining structural compactness.

AI summary
A power supply system (10) for supplying power to a power system of an electric tractor and comprises a bracket (100) that is provided above and below a frame of a transport trailer, first cases (200) that are provided on the bracket and first power battery packs that are suspended inside the first case. Each of the first cases is provided with a first ventilation structure and a second ventilation structure (211) so that while the transport trailer is moving, wind can enter the first case from the first ventilation structure and be discharged from the second ventilation structure, thus achieving further cooling and heat dissipation for the first power battery packs and avoiding service life being impacted due to the first power battery pack overheating.
