Automotive Power Connection Unit for Adding Sub-Power Sources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems require extensive exchange of harnesses and electrical power distribution boxes when adding a sub-power source, which is inefficient and cumbersome.
Innovation Solution
An electrical connection unit with multiple power paths and fuse attachment parts allows seamless integration of additional power sources by connecting a second power source to existing paths without necessitating a full exchange of the unit or wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sub-power source is added to the electrical power distribution system, then the system's power supply capability is improved, but the complexity of harness and electrical connection unit exchange increases
Solution Approach 1:
The electrical connection unit is designed with multiple power source connection terminals and multiple load connection terminals, allowing it to serve as a universal interface for both main and sub-power sources. The unit can handle power distribution from a single power source or multiple power sources simultaneously, making it multi-functional and adaptable to different system configurations without requiring different connection units.
Solution Approach 2:
The electrical connection unit is segmented into distinct functional sections: power source connection terminals, fuse attachment parts, and load connection terminals. This segmentation allows individual components to be added or removed independently. When adding a sub-power source, only the necessary connection terminals and fuses need to be activated, not the entire harness or connection unit.
2Adaptability or versatility
If a sub-power source is added to the electrical power distribution system, then the system's power supply capability is improved, but the time required for system modification increases
Solution Approach 1:
The electrical connection unit is pre-configured with multiple power source connection terminals and multiple load connection terminals before installation. The fuse attachment parts are pre-positioned to accommodate additional fuses for sub-power sources. This preliminary preparation means that when a sub-power source needs to be added, the physical infrastructure is already in place, and only the electrical connections and fuse installations are required, significantly reducing modification time.
3Adaptability or versatility
If multiple power paths are implemented in the electrical connection unit, then the flexibility of power distribution is improved, but the structural complexity of the connection unit increases
Solution Approach 1:
The multiple power paths are achieved through segmentation of the connection unit into distinct terminal sections and fuse attachment parts. Each power path consists of a specific sequence of terminals and fuses, and these paths are structurally separated rather than intertwined. This segmentation allows multiple independent power paths to coexist without creating complex interconnections, maintaining structural clarity while providing distribution flexibility.
4Adaptability or versatility
If the electrical connection unit is designed to accommodate future power source additions, then the system's adaptability is improved, but the initial device complexity increases
Solution Approach 1:
The electrical connection unit incorporates universal connection terminals and standardized fuse attachment parts that can accommodate both current power distribution needs and future expansion requirements. The same terminal structure serves as the interface for both main-power source connections and sub-power source connections, eliminating the need for specialized components for each power source type and reducing overall complexity despite enhanced functionality.
