Solution Approach 1:

The patent creates a virtual copy of the anechoic chamber environment through computer simulation. The simulation model replicates the electromagnetic radiation characteristics and chamber properties, allowing tests to be performed on standard equipment rather than requiring physical anechoic chamber resources. This copying approach maintains measurement accuracy while eliminating resource constraints.

Inventive Principle:

Solution Approach 2:

The patent replaces the physical mechanical system of an anechoic chamber with a computational electromagnetic simulation system. Instead of using physical absorptive materials and controlled environments, the solution uses software-based electromagnetic field calculations to model radiation susceptibility scenarios, substituting computational processes for physical infrastructure.

Solution Approach 1:

The patent creates a virtual replica of the testing environment that allows engineers to perform all necessary adjustments, debugging, and optimization tasks remotely. The simulation interface reproduces device behavior and measurement data, enabling engineers to optimize device performance without physically entering high-radiation areas, thus eliminating health risks while maintaining optimization capability.

Inventive Principle:

Solution Approach 2:

The patent introduces a computer simulation system as an intermediary between the engineer and the actual radiation environment. The simulation acts as a mediator that translates physical device behavior into virtual representations, allowing engineers to interact with and optimize devices through the intermediary interface rather than direct exposure to harmful radiation.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 1:

The patent applies partial action by using simulation only for the portion of testing that requires complex environmental modeling. For simple engineering prediction tests, the simulation provides sufficient accuracy without requiring full formal verification procedures. This partial approach maintains adequate reliability for prediction purposes while avoiding the excessive resource consumption of complete formal testing protocols.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The patent changes the testing parameters from physical environmental conditions to computational model parameters. Instead of controlling physical temperature, humidity, and electromagnetic field strength in an anechoic chamber, the simulation adjusts virtual parameters to represent these conditions, dramatically reducing resource requirements while maintaining test reliability for engineering predictions.
