Underfloor Power Conversion Module for Shorter Vehicle Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle power supply systems with power conversion units disposed in the front or rear sections result in lengthy routing members, which can be inefficient and cumbersome.
Innovation Solution
An electric power supplying module with a module base under the vehicle floor, incorporating a power conversion unit and connectors that shorten the routing members by integrating power distribution directly to load units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power conversion unit is disposed in the front section or rear section of the vehicle, then the power distribution can be achieved, but the routing members become long
Solution Approach 1:
The patent applies dimensionality change by moving the power conversion unit from the conventional front or rear section (one-dimensional positioning along the vehicle length) to the underfloor space (utilizing the third dimension - vertical space). This spatial repositioning allows routing members to connect directly to load units without extending across the entire vehicle length, thereby reducing routing member length while maintaining power distribution functionality.
Solution Approach 2:
The patent segments the power supply system by placing the power conversion unit separately from the battery in the underfloor space, allowing independent optimization of each component's position. This segmentation enables the routing members to be shorter and more efficiently routed to specific load units rather than requiring long connections from front or rear positioning.
2Reliability
If the power conversion unit is disposed in the front section or rear section of the vehicle, then the power supply function is maintained, but the routing members become lengthy and cumbersome
Solution Approach 1:
By utilizing the underfloor space (third dimension), the patent reduces the path length and complexity of routing members while maintaining reliable power supply. The vertical positioning allows direct connections to load units without the need for lengthy horizontal routing across the vehicle.
Solution Approach 2:
The patent extracts the power conversion unit from the conventional front or rear section and relocates it to the underfloor space, separating it from the battery. This extraction allows the routing members to be redesigned as shorter, simpler connections from the underfloor position to various load units, reducing overall system complexity.

AI summary
An electric power supplying module includes a module base, a power conversion unit, a first connector, and a second connector. The module base is disposed under a floor of a vehicle. The power conversion unit is supported by the module base, and converts power supplied from a battery. The first connector is supported by the module base, and is connectable with a first routing member that supplies first power output from the power conversion unit to a first load unit of the vehicle. The second connector is supported by the module base, and is connectable with a second routing member that supplies second power output from the power conversion unit to a second load unit of the vehicle.
