Integrated Vehicle Distributor Corner Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle on-board systems, separate distributors for power and information lead to an increase in the number of members constituting in-vehicle networks, particularly when loads are added at corners, resulting in longer routing distances and increased network complexity.
Innovation Solution
A distributor that integrates power distribution and operation signal communication, using an electronic control unit to manage power supply based on operation information, reducing the number of network members and optimizing routing by being located at vehicle corners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate distributors for power and information are provided, then each distributor can perform its specialized function, but the number of members constituting in-vehicle networks increases
Solution Approach 1:
The patent combines the power distribution distributor and information communication gateway into a single integrated device. This single distributor handles both power supply to loads and information relay between in-vehicle networks, eliminating the need for separate distributors and reducing the total number of network members while maintaining both specialized functions
Solution Approach 2:
The integrated distributor is designed to perform multiple functions: it distributes power to various loads (seats, mirrors, steering wheel) and simultaneously relays information between different in-vehicle networks. This multi-functional design allows one device to replace what would traditionally require two separate devices
2Ease of manufacture
If backbone power supply line is routed over center portion of floor surface, then power can be distributed centrally, but routing distance increases significantly when loads are added at vehicle corners
Solution Approach 1:
The patent segments the power distribution system by placing distributors at corner positions rather than using a single centralized backbone. This segmentation allows power to be distributed from multiple nearby points, reducing the routing distance to loads at corners while maintaining efficient centralized control through the information network
3Adaptability or versatility
If loads are added at vehicle corners, then vehicle functionality is enhanced, but routing distance and number of network members increase
Solution Approach 1:
The integrated distributor acts as an intermediary device positioned at corner locations, locally handling both power distribution and information communication for loads at corners. This intermediary approach allows loads to be added at corners without significantly increasing routing distance, as the distributor is already positioned nearby to serve these loads

AI summary
A distributor configured to be connected to a power supply wire laid in a vehicle, a load for the vehicle to be supplied with power from the power supply wire, and configured to be connected to an operation signal line through which operation information serving as a reference for determining whether to operate or stop the load is transmitted, the distributor including: an electronic control unit configured to distribute power that is supplied from the power supply wire to the load, based on the operation information, wherein the electronic control unit is disposed at a corner of the vehicle.
