Solution Overview

Problem

Modern electronic devices with multiple graphics subsystems face challenges in balancing high performance and battery life due to increased power consumption, particularly in portable devices where higher power graphics subsystems are often reserved for stationary use.

Innovation Solution

Implementing a method to dynamically switch between higher and lower power graphics subsystems based on detected power consumption conditions, such as peripheral connections, energy availability, and user interactions, to optimize power usage by placing the higher power subsystem in a lower power mode when not needed.

1Productivity

If a higher power consuming graphics subsystem is used to provide high performance graphics features, then graphics processing capability is improved, but power consumption increases

Engineering Contradiction:
Improvegraphics processing capabilityVSAvoidpower consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The system dynamically switches between a lower power consumption graphics subsystem and a higher power consumption graphics subsystem based on detected power consumption conditions. The processor monitors conditions such as peripheral connections, energy availability, and user interactions, then selectively activates the appropriate graphics subsystem to match current operational demands, resolving the contradiction between maintaining high graphics capability and reducing power consumption.

2Adaptability or versatility

If multiple graphics subsystems are included in a device, then adaptability to different power conditions is improved, but device complexity increases

Engineering Contradiction:
Improveadaptability to power conditionsVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device incorporates multiple graphics subsystems with different power consumption characteristics, allowing the same device to adapt to various power conditions. The lower power consumption subsystem handles basic graphics tasks during battery operation, while the higher power consumption subsystem provides enhanced graphics capability when plugged into AC power, achieving multi-functionality without requiring separate devices.

AI summary

Many computing device may now include two or more graphics subsystems. The multiple graphics subsystems may have different abilities, and may, for example, consume differing amount of electrical power, with one subsystem consuming more average power than the others. The higher power consuming graphics subsystem may be coupled to the device and used instead of, or in addition to, the lower power consuming graphics subsystem, resulting in higher performance or additional capabilities, but increased overall power consumption. By transitioning from the use of the higher power consuming graphics subsystem to the lower power consuming graphics subsystem, while placing the higher power consuming graphics subsystem in a lower power consumption mode, overall power consumption is reduced.
