Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protection system is provided to insulate high-voltage electrical equipment parts, then safety against electric shock is improved, but device complexity increases
Solution Approach 1:
The patent combines the impact detection function and the insulation protection function into a single integrated system. The conductive filament is embedded within the panel itself, merging the sensor and the protection mechanism into one component, thereby reducing overall system complexity while maintaining safety.
Solution Approach 2:
The system automatically detects impact and triggers insulation of high-voltage components without requiring external intervention or complex control systems. The conductive filament's breakage directly causes the insulation effect, creating a self-activating protection mechanism that simplifies the system architecture.
2Measurement precision
If conductive filament is embedded in panel, then impact detection capability is improved, but manufacturing complexity increases
Solution Approach 1:
The conductive filament is implemented as a thin, flexible conductive element that can be embedded within the panel structure. This thin-film approach allows for simpler integration compared to bulky sensors, reducing manufacturing complexity while maintaining effective impact detection capability through the filament's electrical properties.
