Solution Overview

Problem

Mobile transmitters face high power consumption due to processing input signals across fixed bandwidths, even when not all frequency bands are occupied, leading to unnecessary power usage.

Innovation Solution

A digital processing unit that adjusts its processing frequency range based on the number of data frequency bands in the input signal, allowing for frequency shifting and reduced power consumption by operating within a smaller bandwidth matching the actual data occupancy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the digital processing unit processes input signals across fixed bandwidths to ensure compliance with transmission standards, then transmission standard compliance is maintained, but power consumption increases due to processing unnecessary frequency bands

Engineering Contradiction:

Improvetransmission standard complianceVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The digital processing unit dynamically adjusts its processing frequency range based on the actual number of data frequency bands in the input signal. Instead of operating at fixed bandwidths, the system adapts its processing range to match the actual data occupancy, thereby reducing power consumption while ensuring compliance with transmission standards through proper frequency band processing

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the processing parameter (frequency range) of the digital processing unit based on the detected number of data frequency bands. By adjusting the processing frequency range to match the actual data bandwidth, the system reduces unnecessary power consumption while maintaining the required transmission standard compliance

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the digital processing unit operates at full bandwidth to handle all possible frequency bands, then all data frequency bands can be processed, but power consumption increases significantly

Engineering Contradiction:

Improvedata frequency band coverageVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system extracts and processes only the necessary data frequency bands from the full bandwidth spectrum. By identifying the actual number of occupied frequency bands and adjusting the processing range accordingly, the system removes unnecessary processing of empty frequency bands, thereby reducing power consumption while maintaining the ability to handle all required data frequency bands when present
