Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical power supply networks in vehicles are cumbersome due to the large number of cables and wires, lack modularity, and require extensive re-wiring for additions or modifications, with protective fuses that need replacement, which is inefficient in managing varying energy distribution modes.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fuse boxes with protective fuses are used, then electrical consumers are protected from overcurrent, but the fuses need to be replaced after the circuit is cut, which is inefficient and time-consuming
Solution Approach 1:
The patent transforms the protective device from a passive fuse that melts at a fixed current threshold to an active circuit breaker with adjustable current and time parameters. The control unit allows dynamic adjustment of protection characteristics based on different operating conditions, enabling the same device to provide optimal protection for various electrical consumers without requiring physical replacement.
2Productivity
If modular distribution boxes with intelligent control are implemented, then energy distribution is optimized across different vehicle modes, but the device complexity increases due to additional processors and control systems
Solution Approach 1:
The patent implements a universal control unit that manages multiple functions: monitoring electrical parameters, controlling circuit breakers, adjusting protection settings, and optimizing energy distribution across different vehicle modes. This multi-functional approach consolidates what would otherwise require multiple separate control devices, reducing overall system complexity while maintaining intelligent energy management capabilities.
Solution Approach 2:
The circuit breakers are equipped with automatic tripping and resetting capabilities without manual intervention. The control unit autonomously monitors electrical loads and activates protection mechanisms when thresholds are exceeded, then automatically resets when conditions normalize, eliminating the need for manual fuse replacement or complex manual control interfaces.
3Adaptability or versatility
If a large number of electrical cables and wires are used to connect all distribution boxes, then all electrical consumers can be powered, but the wiring becomes cumbersome and difficult to manage
Solution Approach 1:
The patent divides the electrical distribution system into modular distribution boxes, each serving specific electrical consumers or groups of consumers. Each box contains its own circuit breakers and control logic, allowing independent management of electrical loads. This segmentation reduces the need for extensive point-to-point wiring between all components and enables easier addition or removal of consumers without rewiring the entire system.
