Solution Overview

Problem

Information handling systems face challenges in efficiently transitioning between power conservation and information processing states, particularly in wireless communication devices that rely on battery power, where user input is needed to activate devices from sleep states to working states without manual intervention.

Innovation Solution

A wireless docking system that includes a wireless communication device capable of receiving wireless power and user input, allowing it to establish communication with an information handling system's embedded controller to transition the system from a power conservation state to an information processing state by providing state transition commands, thereby enabling devices to restore stored information and boot the operating system without relying on internal power sources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the information handling system enters a power conservation state to reduce power consumption, then energy efficiency is improved, but the system cannot respond to user input or perform information processing

Engineering Contradiction:

Improvepower consumptionVSAvoidresponsiveness to user input

Core Design Contradiction:

Use of energy by moving objectVSEase of operation

Solution Approach 1:

The system separates the wireless communication device into an independent segment that can operate autonomously from the main information handling system. This segmented architecture allows the communication device to remain active and responsive to user input even when the main system is in a power conservation state, resolving the contradiction between energy efficiency and operational responsiveness.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The wireless communication device acts as an intermediary between the user and the information handling system. It can receive user input and transmit wake-up commands to transition the system from power conservation state to active state, enabling responsive operation without keeping the entire system continuously powered.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the wireless communication device remains active to receive user input, then ease of operation is improved, but power consumption increases

Engineering Contradiction:

Improveability to receive user inputVSAvoidpower consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The system implements dynamic state management where the wireless communication device can transition between different operational states. It remains in a low-power state during normal operation but can be dynamically activated by user input or system events to perform communication functions, optimizing the balance between responsiveness and power consumption.

Inventive Principle:

Principle #15Dynamics

3Productivity

If the system transitions quickly from power conservation state to information processing state, then productivity is improved, but more energy is consumed during transition

Engineering Contradiction:

Improvestate transition speedVSAvoidenergy consumed during transition

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The wireless communication device performs preliminary actions by maintaining minimal operational readiness to detect user input or system events. This preliminary state allows for rapid transition to full information processing mode when needed, reducing the actual transition time and energy consumption compared to transitioning from a completely powered-off state.

Inventive Principle:

Principle #10Preliminary action
