Distributed Junction Block Layout for Shorter Vehicle Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical junction blocks are bulky and inefficient, occupying excessive space and increasing installation costs due to their large size and the need for surplus terminals to accommodate future connections, which is particularly problematic in vehicles with limited space.
Innovation Solution
Implement a method and arrangement using multiple smaller electrical junction blocks instead of a single large one, allowing for modular connections and reducing the length and volume of cable harnesses by connecting electrical units closer to their locations, enabling flexible expansion and reducing the amount of cable required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single large electrical junction block with surplus terminals is used to accommodate future connections, then adaptability is improved, but volume and weight increase
Solution Approach 1:
The patent divides the electrical connection system into multiple smaller junction blocks distributed throughout the vehicle, each serving local electrical units. This segmentation eliminates the need for one large centralized junction block with excessive surplus terminals, reducing overall volume while maintaining adaptability through modular expansion capability.
2Ease of operation
If cable harnesses are routed to a centralized main electrical junction block, then ease of operation is improved, but length and volume of cable harnesses increase
Solution Approach 1:
The patent segments the cable harness routing into multiple local paths that terminate at distributed junction blocks positioned near electrical units. This eliminates the need for long cable runs to a centralized location, reducing total cable length and volume while maintaining operational simplicity through standardized connection procedures.
Solution Approach 2:
The patent transitions from a centralized hierarchical cable routing structure to a distributed network topology, fundamentally changing the dimensional organization of electrical connections. This allows cable harnesses to be routed locally to nearby junction blocks rather than all the way to a central point, significantly reducing length.
3Adaptability or versatility
If a conventional electrical junction block with many terminals is used, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent divides the complex junction block with many terminals into multiple simpler, smaller junction blocks distributed throughout the system. Each smaller block has fewer terminals and simpler internal wiring, reducing individual device complexity while maintaining overall system adaptability through the networked arrangement of multiple blocks.
