Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies multi-functionality by enabling existing mobile phone components (antennae and wireless receiver electronics) to perform both their original communication functions and electromagnetic wave detection functions. The existing antennae are configured to receive both communication signals and electromagnetic wave signals, while the wireless receiver electronics process both types of signals, eliminating the need for separate dedicated detection hardware.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The mobile phone's existing communication infrastructure serves the additional function of electromagnetic wave detection. The antennae and receiver electronics that are already present for normal operation are utilized to detect electromagnetic waves, allowing the device to monitor its own electromagnetic environment without requiring external or additional specialized components.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If multiple antennae are used to expand detection spectrum, then frequency range coverage is improved, but device complexity increases

Engineering Contradiction:

Improvedetection spectrum rangeVSAvoidnumber of components

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple antennae already present in the mobile phone for different communication frequency bands are utilized for electromagnetic wave detection across those same frequency ranges. Each antenna continues to serve its primary communication function while simultaneously contributing to electromagnetic wave detection in its designated frequency band, expanding overall detection coverage without adding dedicated detection components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the communication signal reception function with electromagnetic wave detection function into a single integrated system. Multiple antennae and their associated receiver electronics are combined to perform both functions, allowing the device to detect electromagnetic waves across multiple frequency ranges using the existing communication infrastructure rather than requiring separate detection hardware for each frequency band.

Inventive Principle:

Principle #5Merging (Combining)
