Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate bases are designed for internal combustion engines and electric motors on the same platform, then each powertrain type can be optimized specifically, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent implements a universal base design where the same central base structure can accommodate both internal combustion engines and electric motors through interchangeable interface elements. The base includes standardized mounting points, connection interfaces, and spatial arrangements that work with different powertrain types, eliminating the need for separate dedicated bases for each powertrain technology.
Solution Approach 2:
The patent employs adjustable and reconfigurable interface elements on the base that can be adapted to different powertrain configurations. The base structure allows for dynamic reconfiguration of mounting positions and connection points, enabling the same base to serve multiple powertrain types without requiring complete redesign for each application.
2Adaptability or versatility
If multiple pairs of bases are created for different vehicle lengths on the same platform, then vehicle configuration flexibility is improved, but manufacturing costs and device complexity increase
Solution Approach 1:
The patent divides the base into modular segments with standardized interfaces. The central base can be combined with different front and rear base sections to create configurations suitable for various vehicle lengths and seating arrangements. This segmentation allows a single central base design to support multiple vehicle configurations without requiring completely separate base pairs for each vehicle type.
Solution Approach 2:
The patent creates a universal base platform where the same central base structure can be used across different vehicle configurations by combining it with various front and rear sections. The standardized interfaces and modular design enable the base to adapt to different vehicle lengths, seating capacities, and powertrain types, reducing the need for multiple dedicated base pairs.
3Reliability
If the underbody is dedicated solely to electric motorization with specific floor zones for battery housing, then electric motor optimization is improved, but adaptability to internal combustion engines is lost
Solution Approach 1:
The patent designs the underbody with universal interface elements and standardized mounting zones that can accommodate both electric motor components and internal combustion engine components. The floor zones are configured with adaptable interfaces that can house batteries for electric motors or fuel tanks and engine components for internal combustion engines, maintaining optimization for each powertrain type while preserving cross-compatibility.
Solution Approach 2:
The underbody structure incorporates reconfigurable interface elements that can be adapted to different powertrain requirements. The floor zones and mounting points are designed to be dynamically reconfigurable, allowing the same underbody structure to optimize for electric motorization when equipped with battery systems or adapt to internal combustion engine configurations when equipped with appropriate components.
