Engineering Contradiction Analysis
1Reliability
If conventional aerosol sensors are used in electric vehicle batteries, then basic aerosol detection function is provided, but component misalignment occurs due to mechanical stresses and temperature variations
Solution Approach 1:
The patent combines the light source, lenses, reflector, and photosensor into a single integrated optical component that is rigidly mounted to the circuit board. This merging of components eliminates relative movement between them, preventing misalignment under mechanical stress and temperature variations while maintaining accurate aerosol detection functionality.
2Measurement precision
If integrated optical component with multiple lenses and reflector is implemented, then aerosol detection accuracy is enhanced, but device complexity increases
Solution Approach 1:
Multiple optical elements (lenses and reflector) are merged into a single integrated component that is pre-aligned and rigidly mounted to the circuit board. This integration maintains the precision benefits of multiple optical elements while reducing assembly complexity and eliminating alignment issues that would arise from separate components.
