Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the high-capacity assembled battery is placed in the riding space to maximize electric power supply, then the running distance is improved, but the operating sound becomes louder and affects passenger comfort
Solution Approach 1:
The patent divides the battery system into two separate assembled batteries with different functions: high-power battery for immediate power needs and high-capacity battery for extended range. This segmentation allows placing the noisy high-capacity battery in the luggage space away from passengers while maintaining its function for extending running distance.
Solution Approach 2:
The high-capacity assembled battery is extracted from the riding space and relocated to the luggage space. This extraction removes the noise source from the passenger area while preserving the battery's function of extending running distance through electric power supply.
2Object-affected harmful factors
If the high-power assembled battery is placed in the luggage space to reduce noise, then passenger comfort is improved, but the space for placing luggage is reduced
Solution Approach 1:
The patent segments the battery functions and places the high-power battery in the riding space where it can be integrated into the vehicle structure without significantly impacting luggage space, while the high-capacity battery occupies the luggage space. This segmentation allows both noise reduction and luggage space preservation.
Solution Approach 2:
The patent applies local quality by placing different battery types in different locations based on their specific characteristics: the high-power battery near the motor in the riding space for immediate power needs, and the high-capacity battery in the luggage space for extended range, optimizing both noise distribution and space utilization.
3Temperature
If the high-power assembled battery is placed in the riding space to ensure cooling, then temperature control is improved, but the heat production affects the riding space environment
Solution Approach 1:
The patent segments the thermal management requirements by placing the heat-generating high-power battery in the riding space where cooling air is readily available, while the high-capacity battery in the luggage space has separate thermal management. This segmentation allows targeted cooling strategies for each battery type.
Solution Approach 2:
The patent uses air as an intermediary cooling medium that flows from the riding space to cool the high-power battery. The air circulation system acts as a mediator that transfers heat away from the battery without direct thermal contact, preventing heat buildup while maintaining the battery's operational temperature.
4Device complexity
If both high-capacity and high-power batteries are placed together in one location to simplify structure, then device complexity is reduced, but noise and heat management become difficult
Solution Approach 1:
The patent segments the battery system into two physically separate assembled batteries located in different spaces: the high-power battery in the riding space and the high-capacity battery in the luggage space. This segmentation simplifies the overall structure while enabling independent noise and heat management for each battery type based on their location-specific characteristics.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances vehicle salability, reduces noise and heat issues, ensures longer running distance, and facilitates easier battery replacement and capacity adjustments, improving overall performance and user experience.
Implementation Method 1
Since the high-power assembled battery is placed in the riding space, air in the riding space can be directed to the high-power assembled battery to suppress a rise in temperature of the high-power assembled battery resulting from the heat production and the like.
Implementation Method 2
The high-power assembled battery can achieve charge and discharge with the current larger than that of the high-capacity assembled battery and thus tends to produce more heat. Since the amount of heat production is proportional to the square of the value of the current, the high-power assembled battery having the value of the current higher than that of the high-capacity assembled battery tends to produce more heat.

AI summary
[PROBLEM] To place a high-power assembled battery and a high-capacity assembled battery at optimal positions in a vehicle. [SOLVING MEANS] A vehicle has a motor and an engine each serving as a driving source for running the vehicle, and assembled batteries each capable of supplying an electric power to the motor. The assembled batteries include a high-power assembled battery and a high-capacity assembled battery. The high-power assembled battery is capable of charge and discharge with a current relatively larger than that in the high-capacity assembled battery, and the high-capacity assembled battery has an energy capacity relatively larger than that of the high-power assembled battery. In running of the vehicle using an output from the motor with the engine stopped, the high-capacity assembled battery supplies a more electric power to the motor than that in the high-power assembled battery. The high-power assembled battery is placed in a riding space where a passenger rides, and the high-capacity assembled battery is placed in a luggage space different from the riding space.
