Intelligent Power Distribution for Vehicle Starting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heavy electrical loads can sag the vehicle's electrical system, making it difficult to start the vehicle, as existing technologies either oversize the power source or undersize the loads, leading to inefficiencies or lack feedback control during startup.
Innovation Solution
An intelligent power distribution system with controllable switches that progressively connect loads to the vehicle's electrical source only when the power is stable, ensuring a controlled and sequential startup, prioritizing critical loads and monitoring stability to prevent voltage dips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If all loads are connected simultaneously during vehicle startup, then the power distribution system can provide full power to all electrical loads, but the electrical system voltage sags and making vehicle starting difficult
Solution Approach 1:
The patent segments the electrical loads into multiple groups or individual loads, each controlled by separate switches. Instead of connecting all loads simultaneously, the system progressively closes switches to connect loads in a controlled sequence. This segmentation allows the power source to deliver required power without overwhelming the electrical system during startup, preventing voltage sag while maintaining reliable vehicle starting.
2Power
If the power source is oversized to handle all loads simultaneously, then sufficient power is available for all loads, but the system becomes less efficient and more expensive
Solution Approach 1:
The patent implements a dynamic power distribution system where switches are controlled based on real-time monitoring of power source stability. The system adaptively manages load connections by progressively closing switches only when the power source can reliably support additional loads. This dynamic approach allows a properly sized power source to efficiently handle varying load requirements without needing to be oversized for peak simultaneous demand.
3Reliability
If switches are closed progressively to stabilize power, then vehicle starting is facilitated and voltage stability is maintained, but the startup process takes longer
Solution Approach 1:
The patent employs periodic action by monitoring power source stability at regular intervals and progressively closing switches based on these periodic checks. The system continuously monitors whether the power source can support additional loads and closes switches in a rhythmic, controlled manner. This periodic monitoring and incremental load connection maintains voltage stability while minimizing startup time through efficient, systematic progression.
4Device complexity
If traditional power distribution without progressive switching is used, then the system is simpler and faster to implement, but it cannot detect load faults or validate load operation
Solution Approach 1:
The patent implements feedback mechanisms where the monitoring of power source stability provides information about load conditions. By observing whether power remains stable when switches are closed, the system can detect faults in loads or wiring. If a fault is detected (indicated by abnormal voltage drops or instability), the system can prevent further switch closure or trigger alarm conditions. This feedback-based approach enables fault detection and load validation while maintaining relatively simple system architecture.

AI summary
To start a vehicle, power is provided from the vehicle's electrical source to electrical load(s) in the vehicle. Heavy electrical load(s) can sag the vehicle's electrical system and make starting the vehicle difficult. The following embodiments can address this problem by providing an intelligent power distribution system that uses controllable switch(es) to selectively connect load(s) to the vehicle's electrical source in a controlled, progressive manner. Connecting load(s) in a controlled fashion can facilitate the starting of the vehicle by avoiding having electrical load(s) present at start-up.
