Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed energy storage system is used in vehicles, then the vehicle structure is simple, but the vehicle cannot adapt to different applications
Solution Approach 1:
The energy storage system is divided into multiple independently removable battery modules (first battery module, second battery module, third battery module) that can be selectively installed and removed. Each module contains a separate array of batteries, allowing the system to be segmented into discrete, interchangeable units that simplify adaptation to different applications.
Solution Approach 2:
The energy storage system is designed to be dynamically reconfigurable, transitioning from a static fixed configuration to a dynamic system where battery modules can be added, removed, or repositioned based on operational requirements. This dynamic capability enables the vehicle to adapt its energy storage capacity to match different application demands.
2Adaptability or versatility
If multiple battery modules are installed for reconfiguration, then the vehicle can adapt to different applications, but the vehicle structure becomes more complex
Solution Approach 1:
The chassis is designed with universal mounting structures and standardized interfaces that can accommodate different battery modules. The frame rails and support structures serve multiple functions: structural support, battery module mounting, and electrical connection pathways. This multi-functionality reduces the need for application-specific modifications.
Solution Approach 2:
Different regions of the chassis are designed with specific local qualities to facilitate battery module installation and removal. The frame rails include designated mounting locations with appropriate fastening mechanisms, while electrical connections are positioned at accessible locations. This localized optimization simplifies the overall reconfiguration process.
3Ease of operation
If battery modules can be selectively removed, then operational flexibility is enhanced, but the installation and removal process becomes more complex
Solution Approach 1:
The battery system is segmented into modular units with standardized mechanical and electrical interfaces. Each battery module is designed as a self-contained unit with integrated mounting features and connection points, allowing for tool-free or minimal-tool installation and removal by end users.
Solution Approach 2:
The chassis is pre-configured with mounting structures, fastening mechanisms, and electrical connection points during manufacturing. Wire harnesses and electrical connectors are pre-positioned to align with battery module interfaces, eliminating the need for complex wiring work during field installation or removal operations.

AI summary
A vehicle includes a chassis including a first frame rail and a second frame rail, a tractive element coupled to the chassis, a drive motor configured to drive the tractive element to propel the vehicle, and an energy storage system. The energy storage system includes a first battery module and a second battery module. The energy storage system is selectively reconfigurable between (a) a first configuration in which the first battery module and the second battery module each provide electrical energy to the drive motor and (b) a second configuration in which the first battery module is removed from the vehicle and the second battery module provides electrical energy to the drive motor.
