Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If background processes are allowed to run simultaneously with foreground applications, then device functionality and application performance are improved, but power consumption increases rapidly

Engineering Contradiction:

Improvedevice functionalityVSAvoidpower consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic power management by adjusting the operational state of background processes based on real-time power consumption monitoring. The system transitions background processes between active and suspended states dynamically, allowing them to run when power thresholds are not exceeded and suspending them when power consumption limits are approached, thus resolving the contradiction between maintaining device functionality and controlling power usage.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the operational parameters of background processes by modifying their execution priority and resource allocation based on power consumption levels. When power consumption exceeds predetermined thresholds, the system adjusts parameters such as process scheduling priority and network communication frequency, enabling the device to maintain essential functionality while reducing overall power consumption.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If background processes communicate frequently with other devices, then data synchronization and application responsiveness are improved, but power is rapidly consumed

Engineering Contradiction:

Improvedata synchronizationVSAvoidpower loss

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent implements periodic monitoring of power consumption by background processes at predetermined intervals. Instead of continuous monitoring, the system checks power consumption levels at specific time points, allowing background processes to communicate periodically rather than continuously. This approach maintains data synchronization reliability while significantly reducing the energy loss associated with constant communication monitoring.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system employs feedback mechanisms where power consumption data from background communication processes is continuously monitored and fed back to the power management module. Based on this feedback, the system dynamically adjusts communication frequency and data synchronization intervals, reducing communication activity when power consumption is high while maintaining synchronization reliability when power levels are acceptable.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If network communication is continuously enabled for background processes, then application functionality and data updates are maintained, but device usage time is shortened

Engineering Contradiction:

Improveapplication functionalityVSAvoiddevice usage time

Core Design Contradiction:

Adaptability or versatilityVSDuration of action of moving object

Solution Approach 1:

The patent implements preliminary power consumption assessment before allowing background processes to initiate network communication. The system evaluates predicted power consumption levels and communication requirements in advance, pre-configuring communication parameters and data buffering strategies. This preliminary action ensures that background processes can maintain application functionality without unexpectedly consuming excessive power that would shorten device usage time.
