Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If lead-acid batteries are used in vehicles, then the battery structure is simple and technology is mature, but the battery generates heavy metals and waste liquid that harm the environment and human health
Solution Approach 1:
The patent changes the chemical composition parameters of the battery from lead-acid to lithium-ion or other alternative chemistries, fundamentally altering the material parameters to eliminate heavy metal pollution while maintaining battery functionality
Solution Approach 2:
The patent employs composite battery materials, specifically lithium-ion battery components, which combine multiple materials with different properties to achieve both environmental friendliness and high performance, replacing the simple lead-acid composition
2Quantity of substance
If lead-acid batteries are used in vehicles, then the battery provides power storage, but the charging time is long
Solution Approach 1:
The patent changes the electrochemical parameters of the battery system by adopting lithium-ion technology, which has fundamentally different charge acceptance characteristics compared to lead-acid batteries, enabling faster charging while maintaining or increasing capacity
Solution Approach 2:
The patent implements a monitoring unit that continuously monitors battery voltage and provides feedback to the power management module, which dynamically adjusts charging parameters in real-time to optimize charging speed while preventing overcharging, thereby reducing overall charging time
3Power
If lead-acid batteries are used in vehicles, then the battery provides power for starting, but the battery weight is high
Solution Approach 1:
The patent changes the density and specific energy parameters of the battery by transitioning to lithium-ion or nickel-metal hydride chemistry, which offers significantly higher specific energy (energy per unit weight), thereby reducing battery weight while maintaining or enhancing starting power capability
4Power
If lead-acid batteries are used in vehicles, then the battery powers the starting motor, but the battery life performance reduces when capacity is less than half charge
Solution Approach 1:
The patent implements a monitoring unit that continuously monitors battery voltage and provides feedback to the power management module, which prevents discharge below minimum voltage thresholds and stops charging at maximum voltage thresholds, ensuring the battery operates within optimal voltage ranges that preserve battery life and reliability
Solution Approach 2:
The patent takes preliminary action by establishing voltage thresholds before the battery reaches damaging states, using the monitoring unit to detect voltage levels and the power management module to preemptively adjust power flow, preventing over-discharge and over-charging conditions that would reduce battery lifespan
5Power
If traditional battery systems are used in vehicles, then the battery provides power, but the vehicle can be stolen easily when left unattended
Solution Approach 1:
The patent integrates multiple functions into the battery system: power provision through the battery module, monitoring through the monitoring unit, control through the power management module, and security through the wireless security module with Bluetooth transmitter, creating a multi-functional system that combines power supply with theft prevention capabilities
Solution Approach 2:
The patent introduces a wireless security module with Bluetooth transmitter as an intermediary between the battery system and the user's portable device, enabling remote monitoring and control capabilities that prevent theft without interfering with the normal power provision function

AI summary
A power supply system having a wireless security module for vehicles is provided. The power supply system comprises a battery module, a power management module, an energy management module and the wireless security module. The battery module powers a starting motor of a vehicle. The power management module is used to receive a power from a power generating device. The power management module transmits the power of the power generating device into the battery module. The power management module comprises a monitoring unit and a controlling unit. The monitoring unit is used to monitor a voltage value of the battery module. When the voltage value monitored is equal to a minimum setting, the power management module is used to prevent the battery module from powering the starting motor. When the voltage value monitored is equal to a maximum setting, the power management module stops powering the battery module. The controlling unit is used to control a current value outputted from the battery module. Furthermore, when the voltage value of the battery module is equal to the maximum setting, the energy management module is used to receive a power from the power generating device. The power is transmitted into the vehicle by the energy management module.
