Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic switching between LTE and NR communication modules based on real-time detection of external device capabilities. The system transitions from a static dual-module operation to a dynamic selection mechanism, enabling the vehicle electronic apparatus to adapt its communication mode according to the broadcast messages received from external devices, thereby reducing power consumption while maintaining compatibility.

Inventive Principle:
