Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a roll stabilizer device is added to reduce rolling movements, then driving safety is improved, but device complexity increases
Solution Approach 1:
The battery receiving device is integrated with the roll stabilizer device structure, combining two functional systems into a unified assembly. The battery mounting structure utilizes the same structural elements and mounting points as the roll stabilizer, thereby reducing overall device complexity while maintaining both roll stabilization and battery integration functions.
Solution Approach 2:
The roll stabilizer device structure serves multiple functions: it provides roll stabilization during vehicle operation and simultaneously serves as a mounting structure for the battery. This multi-functional design eliminates the need for separate mounting structures, reducing device complexity while improving driving safety through the roll stabilizer.
2Volume of moving object
If batteries are mounted above the push tube frame, then space utilization is improved, but manufacturing precision requirements increase
Solution Approach 1:
The receiving device structure is pre-integrated into the vehicle chassis assembly during manufacturing, with predetermined mounting positions and attachment points. This preliminary integration establishes precise reference frames and mounting locations before battery installation, ensuring accurate positioning while simplifying the overall manufacturing process.
Solution Approach 2:
The receiving device acts as an intermediary component between the chassis and the battery, providing a standardized interface with predetermined mounting features. This intermediary structure absorbs and compensates for manufacturing tolerances, ensuring precise battery positioning without requiring extremely high manufacturing precision across all components.
3Adaptability or versatility
If electric machines are integrated into the drive train, then adaptability is improved, but device complexity increases
Solution Approach 1:
The vehicle assembly is designed with dynamic configurability, allowing the drive train to operate in multiple modes (conventional or electric) based on operational requirements. The receiving device and battery integration enable flexible deployment of electric machines without permanently fixing the drive train architecture, thereby improving adaptability while managing complexity through modular design.
Solution Approach 2:
The drive train system is segmented into modular components, with electric machines and battery systems that can be independently added or removed. This segmentation allows the vehicle to maintain its base conventional drive train structure while optionally integrating electric propulsion components, improving adaptability without substantially increasing the complexity of the core system.
