Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If sustainable energy modules are integrated into aircraft propulsion systems, then energy efficiency and sustainability are improved, but operational speed and maintenance efficiency deteriorate due to complex replacement procedures
Solution Approach 1:
The energy module is designed as a separable component that can be independently removed from the aircraft propulsion system. The connector mechanism divides the integration into discrete engagement and disengagement states, allowing the energy module to be quickly swapped without disassembling the entire propulsion system, thus maintaining high operational speed while enabling sustainable energy integration
Solution Approach 2:
Spare energy modules are pre-positioned in a repository on the ground vehicle, ready for immediate installation. The ground vehicle is pre-configured with the replacement module, eliminating the need for on-site preparation or complex recharging procedures during maintenance operations, thereby preserving operational speed
2Use of energy by moving object
If sustainable energy modules are integrated into aircraft propulsion systems, then sustainability is improved, but maintenance time increases due to complex replacement procedures
Solution Approach 1:
The connector is designed as a modular interface that separates the energy module from the propulsion system into distinct components. This segmentation allows maintenance personnel to quickly disconnect and replace the energy module without time-consuming disassembly procedures, reducing maintenance time while sustaining the use of sustainable energy sources
Solution Approach 2:
The system enables rapid self-service replacement of energy modules through the automated connector mechanism. The ground vehicle automatically positions and installs the replacement module, minimizing the need for manual intervention and reducing overall maintenance time while maintaining sustainability
3Ease of operation
If connectors are designed for easy engagement and disengagement of energy modules, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The connector mechanism extracts the complex engagement and disengagement logic into a dedicated, self-contained device. This separation allows the main propulsion system to remain simple while the connector handles the complexity of secure attachment and quick release, achieving ease of operation without overwhelming system complexity
Solution Approach 2:
The connector acts as an intermediary component between the energy module and the propulsion system. It absorbs the complexity of the connection interface, providing simple engagement and disengagement operations for the user while managing the intricate details of electrical and mechanical connections internally
4Productivity
If ground vehicles are equipped with repositories for spare energy modules, then productivity is improved through quick swapping, but device complexity increases
Solution Approach 1:
The repository for spare energy modules is merged with the ground vehicle's existing structure and operational systems. By integrating the storage function into the vehicle's framework rather than adding a completely separate system, the ground vehicle achieves enhanced maintenance efficiency while minimizing the increase in overall device complexity
