Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If batteries are used for energy storage in electric vehicles, then long energy retention is achieved, but charge time becomes excessively long (12-14 hours)
Solution Approach 1:
The patent combines ultracapacitors and batteries into a single hypercapacitor assembly where ultracapacitors handle fast charging and discharging operations while batteries provide long-term energy storage, resolving the contradiction between fast charging and long energy retention
2Productivity
If ultracapacitors are used for energy storage, then fast charging is achieved, but self-discharge rate increases (10-20% per day)
Solution Approach 1:
The hypercapacitor assembly merges ultracapacitors with batteries, where the battery component compensates for the ultracapacitor's high self-discharge rate by providing stable long-term storage, enabling fast charging without excessive energy loss
3Reliability
If wired charging systems are used, then reliable power transfer is achieved, but system complexity and inconvenience increase
Solution Approach 1:
The patent replaces the mechanical wired charging connection system with a wireless power transfer system using electromagnetic fields, eliminating cables and connectors while maintaining reliable power transfer to the hypercapacitor assembly
4Ease of operation
If wireless charging systems are used, then convenience is improved, but energy transfer efficiency decreases
Solution Approach 1:
The patent implements a wireless charging system that uses optimized electromagnetic field coupling to transfer power to the hypercapacitor assembly, providing convenience while minimizing energy transfer losses through efficient field coupling design
