Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the battery submodule is integrated into the vehicle frame, then the vehicle structure is simplified, but the security against theft is compromised
Solution Approach 1:
The battery submodule is segmented from the vehicle frame, creating a separate interchangeable module that can be easily removed and carried away. This segmentation allows the battery to be separated from the vehicle structure, reducing theft risk while maintaining structural simplicity through standardized interfaces.
Solution Approach 2:
The battery submodule is extracted as a distinct, removable component from the vehicle frame. The interchangeable module design allows the battery to be taken out separately, enabling users to carry valuable components away from the vehicle, thereby addressing the security concern while keeping the overall vehicle structure simple.
2Strength
If the cargo compartment is fixed to the vehicle frame, then the structural integrity is maintained, but the versatility for different cargo configurations is limited
Solution Approach 1:
The cargo compartment is segmented as part of an interchangeable module that can be easily attached and detached from the vehicle frame. This segmentation maintains structural integrity when connected through standardized interfaces while enabling versatile cargo configurations by allowing different module types to be swapped as needed.
Solution Approach 2:
The interchangeable module design provides universality, allowing a single vehicle frame to accommodate multiple different cargo configurations through standardized interfaces. Different modules can be attached to the same frame, enabling the vehicle to adapt to various cargo needs while maintaining structural integrity through consistent connection points.
3Stability of the object's composition
If the battery submodule is permanently mounted, then the vehicle stability is improved, but the ease of removal for charging or replacement is reduced
Solution Approach 1:
The battery submodule is segmented as a separate interchangeable module with standardized interfaces. This segmentation allows the battery to be easily removed and replaced without compromising vehicle stability when the module is connected, as the standardized interfaces ensure proper alignment and secure attachment during operation.
Solution Approach 2:
The interchangeable module design introduces dynamic capability to the battery mounting system. The module can be securely attached during operation to maintain vehicle stability, yet easily detached when needed for charging or replacement. The standardized interfaces enable this dynamic transition between fixed and removable states.
4Reliability
If the electromechanical interface is integrated into the frame, then the electrical connection reliability is improved, but the ease of module replacement is reduced
Solution Approach 1:
The electromechanical interface is segmented as part of the interchangeable module assembly rather than being permanently integrated into the frame. This segmentation allows the electrical connections to be reliably established when the module is attached, while enabling easy module replacement by simply detaching the entire module with its integrated interface.
Solution Approach 2:
The electromechanical interface is merged with the interchangeable module, creating a unified assembly that can be easily attached and detached. This merging ensures reliable electrical connections when the module is in place, while maintaining ease of replacement by allowing the entire module-interface assembly to be swapped as a single unit.

AI summary
An electric vehicle features a reverse tricycle frame with a longitudinal tube, steering housing, and suspension for dual front wheels. It employs an electric motor to drive the rear wheel and supports an interchangeable module. The module integrates a cargo compartment and a battery submodule beneath its floor. A module-mounted rail interface engages the frame-mounted rail, securing the module in two spatial dimensions, while a module-mounted electromechanical interface connects via translation to the frame-mounted electromechanical interface, locking the module in a third spatial dimension and electrically linking the battery to the motor.
