Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple functions are integrated into a torque transmission device for hybrid drive trains, then the operational reliability and space utilization improve, but the device complexity increases
Solution Approach 1:
The patent combines a torque transmission device with a torque damper device into a single integrated unit. The torque transmission device includes a first input element connected to a combustion engine, a first output element connected to a transmission, and a second input element connected to an electromechanical energy converter, while the torque damper device is directly integrated into this structure. This merging of multiple functions into one device improves operational reliability and optimizes installation space without excessively increasing complexity through systematic integration.
Solution Approach 2:
The integrated torque transmission device performs multiple functions simultaneously: it transmits torque from both the combustion engine and electromechanical energy converter, dampens torsional vibrations, and controls power distribution between different drive sources. This multi-functionality allows a single device to replace what would traditionally require separate components, improving reliability while managing complexity through functional consolidation.
2Volume of moving object
If the torque transmission device is compact to fit limited installation space, then the space utilization improves, but the manufacturing precision requirements increase
Solution Approach 1:
The torque damper device is nested within the torque transmission device structure, with the damper input element and damper output element integrated into the same housing and component arrangement. This nested configuration maximizes space utilization by placing one device inside another, achieving a compact overall footprint while maintaining adequate clearance and assembly tolerances through careful structural design.
3Reliability
If the torque transmission device integrates vibration damping functionality, then the operational reliability improves, but the device complexity increases
Solution Approach 1:
The torque damper device is merged with the torque transmission device by directly connecting the damper input element to the first input element and the damper output element to the first output element. This integration allows vibration damping functionality to be incorporated without requiring entirely separate mounting structures, improving reliability by reducing the number of external connections and potential failure points while managing complexity through shared structural elements.
