Solution Overview

Problem

Conventional computing devices face inefficiencies in resource utilization due to unnecessary pre-emptive switching between low-power and high-performance operating domains, leading to reduced battery life and user experience degradation from perceptible delays.

Innovation Solution

Simulating a transition between operating domains by using a low-power processor to perform initial domain-switching processes, allowing the device to maintain the appearance of high-performance operation without actual domain change, thereby optimizing resource utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If the device pre-emptively switches from low-power operating domain to high-performance operating domain, then the device can respond faster to user interactions, but battery life is reduced due to unnecessary domain switches

Engineering Contradiction:

Improveresponse speedVSAvoidbattery life

Core Design Contradiction:

SpeedVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary analysis of user interaction patterns and pre-loads necessary resources into buffer memory before actual domain switching is needed. This allows the low-power processor to prepare data and instructions in advance, so when switching to high-performance mode occurs, the transition is faster and more efficient, reducing the duration and energy cost of the high-performance state

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system creates copies of frequently accessed data and instructions in buffer memory while operating in low-power mode. These copies are prepared in advance using the low-power processor, allowing the high-performance processor to immediately access pre-copied data when needed, eliminating the need to transfer large amounts of data during domain switching and thus reducing energy consumption

Inventive Principle:

Principle #26Copying

2Adaptability or versatility

If the device frequently switches between operating domains, then the device can adapt to varying computational demands, but user experience degrades due to perceptible delays

Engineering Contradiction:

ImproveadaptabilityVSAvoidtransition delay

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary preparation of domain switching resources including pre-loading instructions and data into buffer memory, and pre-configuring hardware states. This preliminary action reduces the actual transition time between domains, making frequency switching less perceptible to users while maintaining adaptability to computational demands

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system introduces buffer memory as an intermediary layer between the low-power and high-performance processors. This buffer acts as a mediator that holds pre-prepared data and instructions, allowing smoother transitions between domains by eliminating direct data transfer delays and reducing the perceptible impact of domain switching on user experience

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If the device maintains high-performance operating domain ready state, then the device can immediately handle computationally expensive operations, but energy expenditure increases

Engineering Contradiction:

Improvecomputational capabilityVSAvoidenergy expenditure

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The system performs only the necessary minimum preparation actions in the low-power domain rather than fully activating the high-performance domain. By partially preparing data in buffer memory and only switching domains when absolutely necessary, the system avoids the excessive energy expenditure of maintaining the high-performance domain in a ready state while still achieving high productivity when needed

Inventive Principle:

Principle #16Partial or excessive action
