Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate FM receiver structure is used, then signal processing capability is improved, but device size increases

Engineering Contradiction:

Improvesignal processing capabilityVSAvoiddevice size

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent combines the FM receiver and mobile communication device into a single integrated receiver unit. The mixed signal device includes both an FM receiver section and a mobile communication receiver section, allowing both functions to share common components such as the antenna, mixed signal device, baseband processing device, and speaker, thereby reducing overall device size while maintaining full signal processing capability

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated receiver is designed to handle multiple signal types (FM radio signals and mobile communication signals) through universal components. The mixed signal device can selectively process different frequency bands and signal types, and the baseband processing device can handle both analog FM signals and digital mobile communication signals, making the system multi-functional without requiring separate dedicated structures

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If separate FM receiver structure is used, then signal processing capability is improved, but power consumption increases

Engineering Contradiction:

Improvesignal processing capabilityVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by stationary object

Solution Approach 1:

The patent merges the FM receiver and mobile communication device into a single integrated receiver, allowing shared power consumption across common components. The mixed signal device, baseband processing device, and speaker are共用 by both functions, eliminating the need for separate power supplies and reducing total power consumption compared to maintaining entirely separate receiver structures

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If separate FM receiver structure is used, then signal processing capability is improved, but manufacturing cost increases

Engineering Contradiction:

Improvesignal processing capabilityVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent integrates both receiver functions into a single device structure, reducing the total number of components that need to be manufactured and assembled. By sharing common components (antenna, mixed signal device, baseband processing device, speaker), the manufacturing complexity and cost are reduced compared to producing separate FM receivers and mobile communication devices as independent units

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The mixed signal device and baseband processing device are designed as universal components that can handle multiple signal types. This multi-functionality allows a single manufacturing process to produce devices capable of both FM radio and mobile communication, eliminating the need for separate manufacturing lines and reducing overall production costs

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Adaptability or versatility

If separate processing units are used, then signal handling is improved, but device complexity increases

Engineering Contradiction:

Improvesignal handling capabilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple signal handling functions into a single integrated receiver with shared processing components. The mixed signal device consolidates signal reception and initial processing, while the baseband processing device handles both analog and digital signal processing for different communication types, thereby reducing device complexity while maintaining comprehensive signal handling capability

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A multi-band communication device configured with a mobile communication device for voice or data communication over a cellular, satellite or other communication network and configured with an auxiliary communication system configured to receive and/or transmit an auxiliary communication signal. The mobile communication device and auxiliary communication system are integrated into the same components within the multi-band communication device thereby allowing the components to share the processing tasks associated with each communication device within the multi-band communication device. The auxiliary communication device may be configured to operate during standby mode of the mobile communication device, such as during reception of a paging signal. The auxiliary communication device may comprise, but is not limited to, AM or FM radio, personal communication devices such as FRS, GMRS, or weather band radio.
