Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If current power batteries are used in E-powered vehicles, then the vehicles can operate with existing battery technology, but the power output is insufficient for long-distance travel and the cost is high
Solution Approach 1:
The patent combines a battery and a supercapacitor into a single integrated energy storage device. The battery provides sustained energy storage while the supercapacitor delivers high power bursts, resolving the contradiction by merging two different energy storage mechanisms to achieve both sufficient power and operational reliability for long-distance travel
Solution Approach 2:
The patent uses a composite electrode structure combining battery materials with supercapacitor materials. This composite approach allows the integrated device to exhibit both battery-like energy storage characteristics and supercapacitor-like power delivery capabilities, simultaneously achieving high power output and sufficient operational reliability
2Power
If expensive power batteries are used to achieve sufficient power, then the vehicles can operate over long distances, but the cost increases significantly
Solution Approach 1:
The integrated energy storage device merges battery and supercapacitor technologies into a single unit, allowing the system to achieve high power output for long-distance travel while utilizing the cost-effective supercapacitor component for power delivery, thereby reducing overall manufacturing cost compared to using expensive power batteries alone
Solution Approach 2:
The patent changes the operational parameters by allowing the supercapacitor to handle high-power transient demands while the battery provides baseline energy storage. This parameter differentiation enables the system to achieve sufficient power for long-distance travel at lower cost by optimizing the contribution of each component based on their respective cost-performance characteristics
