Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If Li-Po batteries are used for power storage, then energy density is improved, but safety deteriorates due to flammability and sensitivity to vibration and high temperature
Solution Approach 1:
The patent changes the fundamental energy storage mechanism from chemical reactions (batteries) to electrostatic energy storage (ultracapacitors). This parameter change allows the system to achieve comparable energy density while eliminating flammability and sensitivity to vibration and high temperature, as ultracapacitors use physical charge separation rather than chemical bonds
Solution Approach 2:
The patent replaces the chemical system (batteries relying on chemical reactions) with an electrostatic system (ultracapacitors using electric field energy storage). This substitution eliminates the harmful chemical reactions that cause flammability and degradation under vibration and heat, while maintaining energy storage capability
2Reliability
If thermal batteries are used for long life and harsh environment performance, then reliability is improved, but adaptability deteriorates due to single-use limitation and inability to periodic testing
Solution Approach 1:
The patent transforms the static, single-use thermal battery system into a dynamic, reusable ultracapacitor system. The ultracapacitor can be charged and discharged repeatedly, allowing periodic testing and verification of system functionality while maintaining long life and harsh environment performance through its robust electrostatic energy storage mechanism
3Use of energy by moving object
If traditional batteries are used in power supply system, then energy storage capacity is improved, but device complexity increases due to maintenance requirements and safety management
Solution Approach 1:
The patent implements a self-service system where the ultracapacitor automatically manages its own charging and discharging cycles without requiring external maintenance. The integrated control circuit automatically monitors voltage and current, managing the energy storage and release processes, thereby eliminating the complex maintenance and safety management requirements associated with traditional batteries
4Productivity
If ultracapacitor technology is applied without specific source system design, then energy storage speed is improved, but device complexity increases due to lack of integrated control and monitoring
Solution Approach 1:
The patent merges the control and monitoring functions directly into the source system design, integrating the charging-discharging control circuit with the ultracapacitor module. This integration maintains fast charging-discharging speeds while reducing overall device complexity by eliminating separate control systems and interconnections
