1Power

If multiple microwave sources are arranged in parallel to form a two-dimensional matrix, then the total power of microwave radiation increases, but the synchronization difficulty increases and device efficiency decreases

Engineering Contradiction:

Core Design Contradiction:
PowerVSReliability

Solution Approach 1:

A common resonator is introduced as an intermediary element to couple multiple microwave sources. The resonator acts as a mediator that receives microwave radiation from multiple magnetrons and combines them in phase, enabling synchronization without direct coupling between sources. This resolves the contradiction by providing a centralized coordination mechanism that maintains efficiency while allowing parallel arrangement of multiple sources.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

Multiple microwave sources are merged into a single common resonator structure where their radiations are combined. The resonator integrates the output of multiple magnetrons arranged in parallel, summing their power while maintaining phase coherence through the shared resonant cavity. This combining approach enables high total power output while preserving synchronization through the unified resonant structure.

Solution Approach 1:

The common resonator structure serves multiple functions simultaneously: it acts as the coupling element for microwave synchronization, the combining cavity for power summation, and the primary heat dissipation structure. By making the resonator multi-functional, the design accommodates multiple closely-spaced microwave sources in a compact area while the resonator's large surface area and volume provide adequate heat removal capacity for all sources.
