Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If devices operate in full power mode to maintain communication performance, then communication quality is improved, but energy consumption increases

Engineering Contradiction:

Improvecommunication qualityVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts the operational state of transceivers based on communication needs. Devices switch between full power mode and reduced power mode, activating or deactivating transceivers as required by traffic conditions, thereby optimizing the balance between communication quality and energy consumption

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system implements periodic monitoring of communication traffic patterns and periodically adjusts transceiver states. By checking traffic conditions at regular intervals and switching transceivers between active and inactive states accordingly, the system maintains communication performance when needed while saving energy during low-activity periods

Inventive Principle:

Principle #19Periodic action

2Use of energy by moving object

If devices operate in reduced power mode to save energy, then energy consumption is reduced, but communication responsiveness deteriorates

Engineering Contradiction:

Improveenergy consumptionVSAvoidcommunication responsiveness

Core Design Contradiction:

Use of energy by moving objectVSSpeed

Solution Approach 1:

The system performs preliminary assessment of communication traffic conditions before switching transceivers to inactive state. By monitoring traffic patterns and predicting future communication needs, the system switches transceivers to power-saving mode only when it is safe to do so, preventing responsiveness degradation while maintaining energy savings

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors communication traffic conditions and uses this feedback to dynamically control transceiver states. When traffic activity exceeds predetermined thresholds, the system activates transceivers to maintain responsiveness; when activity remains low, transceivers remain inactive to save energy, creating a responsive feedback-controlled power management system

Inventive Principle:

Principle #23Feedback

3Use of energy by moving object

If transceivers are deactivated to reduce power consumption, then power savings increase, but synchronization maintenance becomes difficult

Engineering Contradiction:

Improvepower consumptionVSAvoidsynchronization

Core Design Contradiction:

Use of energy by moving objectVSStability of the object's composition

Solution Approach 1:

The system extracts and separates synchronization functions from the main transceiver operations. Dedicated synchronization mechanisms operate independently, allowing the system to maintain synchronization continuity even when communication transceivers are deactivated for power saving, thus resolving the conflict between power consumption and synchronization stability

Inventive Principle:

Principle #2Taking out (Extraction)

4Productivity

If multiple transceivers operate simultaneously to handle different service flows, then communication capacity increases, but device complexity increases

Engineering Contradiction:

Improvecommunication capacityVSAvoiddevice complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system merges multiple transceiver functions into a unified power management framework. By consolidating control logic and using centralized monitoring of traffic conditions, the system manages multiple transceivers handling different service flows while reducing overall device complexity through integrated control mechanisms

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A communication device is implemented to perform signal processing based on different dynamic ranges at different times. The device can operate with a first, relatively larger dynamic range during normal operations, and with a second, relatively smaller dynamic range during reduced power or sleep mode operations. The relatively smaller dynamic range may have a relatively higher noise floor than the larger dynamic range. Generally, any desired number of different dynamic ranges may be used at different times and based on different operating conditions. The communication device can include functionality associated with two or more transceivers to support communications based on two or more power modes (e.g., a full power mode, a reduced power mode or a sleep mode, etc.). The communication device may alternatively include two or more separate transceivers to support such communications. An unused transceiver or transceiver functionality may be turned off to provide power savings.
