Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
WiGig coupling and docking operations result in non-effective host system and device power performance due to frequent link accesses and inability to reach deep power save states, leading to increased power consumption and reduced battery life in wirelessly interconnected devices.
Innovation Solution
A power management module that systematically identifies current scenarios and optimizes power settings by adjusting link access schemes, latency tolerance, and idle durations to minimize power dissipation while maintaining performance requirements, using a platform framework that considers WiGig application performance and monitors activity indicators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frequent link accesses are performed to maintain WiGig coupling and docking operations, then communication reliability is improved, but power consumption increases and battery life decreases
Solution Approach 1:
The patent implements dynamic link access schemes that adjust the frequency and timing of link accesses based on current operational scenarios and power conditions. The system transitions between different access patterns (e.g., frequent accesses during active docking, reduced accesses during idle states) to balance communication reliability with power consumption, allowing the device to adapt its behavior to current needs rather than using a fixed access pattern
Solution Approach 2:
The patent employs periodic link accesses with variable periods based on operational state. During active WiGig operations, link accesses occur at shorter intervals to maintain reliability, while during idle or low-activity states, the period between accesses is extended to reduce power consumption. This periodic action with adaptive timing allows the system to maintain necessary communication reliability while minimizing unnecessary power drain
2Productivity
If the system maintains host system responsiveness for WiGig operations, then operational performance is improved, but ability to reach deep power save states is reduced
Solution Approach 1:
The patent implements dynamic power management that adjusts host system responsiveness based on operational scenario. During active WiGig docking operations, the system maintains higher responsiveness to ensure performance requirements are met. During idle periods or when power conservation is prioritized, the system transitions to deeper power save states with reduced responsiveness, dynamically balancing performance needs against battery life extension goals
3Stability of the object's composition
If link access frequency is increased to maintain wireless connection, then connection stability is improved, but power dissipation increases
Solution Approach 1:
The patent implements periodic link access with adaptive period duration. During stable connection periods with low data activity, the system extends the period between link accesses to reduce power dissipation while maintaining connection stability through periodic re-establishment. During periods of higher activity or when connection quality degrades, the period is shortened to maintain stability, creating an adaptive balance between connection stability and energy loss
