Solution Overview

Problem

Computing devices face challenges in maintaining optimal camera operation across varying power states, leading to suboptimal user experiences due to suspended processor operations and limited camera functionality during low power states.

Innovation Solution

A low power manager and camera settings manager dynamically update camera operations based on context data and management policies, ensuring consistent and user-preferred camera functionality even during low power states.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the processor operation is suspended during low power states, then power consumption is reduced, but camera functionality and responsiveness deteriorate

Engineering Contradiction:

Improvepower consumptionVSAvoidcamera functionality

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The system divides power management into two independent components: a low power manager that operates continuously with minimal power to maintain camera functionality, and a camera settings manager that updates camera parameters based on context data. This segmentation allows the low power manager to sustain basic camera operations without requiring full processor operation, thus maintaining camera functionality while reducing overall power consumption.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The low power manager acts as an intermediary between the suspended processor and the camera subsystem. It maintains camera functionality during processor suspension by handling basic camera operations independently, while the camera settings manager serves as another intermediary that dynamically updates camera settings based on context data and management policies, ensuring camera responsiveness without requiring full processor operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Use of energy by moving object

If the processor operation is suspended during low power states, then power consumption is reduced, but system responsiveness deteriorates

Engineering Contradiction:

Improvepower consumptionVSAvoidsystem responsiveness

Core Design Contradiction:

Use of energy by moving objectVSSpeed

Solution Approach 1:

The system performs preliminary actions by having the low power manager continuously monitor and maintain camera functionality even before processor suspension occurs. The camera settings manager proactively updates camera settings based on context data in advance, ensuring that the camera subsystem is already optimized and responsive when the processor enters low power state, eliminating responsiveness delays.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The low power manager and camera settings manager serve as intermediary components that maintain system responsiveness independently of the main processor. The low power manager handles time-sensitive camera operations continuously, while the camera settings manager dynamically adjusts camera parameters based on context data, ensuring the system remains responsive to camera-related events even when the main processor is suspended.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Use of energy by moving object

If camera operation is limited during low power states, then power consumption is reduced, but user experience deteriorates

Engineering Contradiction:

Improvepower consumptionVSAvoiduser experience

Core Design Contradiction:

Use of energy by moving objectVSEase of operation

Solution Approach 1:

The system dynamically adapts camera operation modes based on context data and management policies. The camera settings manager continuously updates camera parameters such as frame rate, resolution, and activation thresholds according to the current operational context, allowing the camera to provide appropriate functionality for different user scenarios while optimizing power consumption for each specific context.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The camera settings manager changes camera operational parameters dynamically based on context data and management policies. It adjusts parameters such as camera activation thresholds, frame capture rates, and operational modes to match user preferences and environmental contexts, ensuring optimal user experience while minimizing power consumption for each specific situation.

Inventive Principle:
