Solution Overview

Problem

Personal assistant applications on stationary computers, such as laptops and desktops, cannot receive voice commands from portable transceiver units when the host computer is in a low-power sleep mode, preventing remote access and interaction.

Innovation Solution

A portable transceiver unit with a microphone for voice command input, a wireless transceiver for communication with the host computer, and a motion sensor to detect predetermined motion patterns, which triggers a wake signal to awaken the host computer, allowing voice commands to be processed and responses to be transmitted back.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the host computer is in low-power sleep mode to conserve energy, then energy consumption is reduced, but the computer cannot receive voice commands from portable transceiver units

Engineering Contradiction:
Improveenergy consumptionVSAvoidremote access capability
Core Design Contradiction:
Use of energy by moving objectVSEase of operation

Solution Approach 1:

The system performs preliminary action by sending a wake signal before the actual voice command interaction. The portable transceiver unit detects motion patterns and proactively transmits a wake signal to the host computer, preparing the system in advance for the upcoming voice command session. This ensures the computer is fully operational and ready to receive commands before the user actually issues them.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The portable transceiver unit acts as an intermediary between the user and the host computer. It detects motion patterns, transmits wake signals, and relays voice commands to the computer. This intermediary device enables remote interaction without requiring the computer to continuously monitor for commands, thus maintaining energy efficiency while enabling access.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the host computer remains awake to receive voice commands continuously, then remote access is enabled, but energy consumption increases

Engineering Contradiction:
Improvevoice command receptionVSAvoidenergy consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

Instead of continuous operation, the system uses periodic action triggered by specific events. The host computer transitions between sleep and active states based on periodic wake signals from the portable transceiver unit. This event-driven approach allows the computer to remain in low-power mode during extended periods while still being accessible when needed.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The portable transceiver unit provides self-service functionality by autonomously detecting motion patterns and initiating wake signals without requiring computer intervention. The system serves itself by automatically transitioning from sleep mode when motion is detected, eliminating the need for continuous monitoring by the computer.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If motion sensors and wake signal functionality are added to enable remote access, then interaction capability is improved, but device complexity increases

Engineering Contradiction:
Improveremote interaction capabilityVSAvoidtransceiver unit components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The portable transceiver unit is designed with multi-functionality, serving as both a wireless audio device and a remote control interface. The motion sensor and wake signal capabilities are integrated into an existing portable device that users already carry, rather than requiring a dedicated remote control system. This universal approach adds remote access functionality without requiring entirely new devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A method includes, with a portable, wireless transceiver, detecting a predetermined motion pattern of the transceiver; and in response to detecting the predetermined motion pattern of the transceiver, transmitting a wireless wake signal from the portable transceiver to a sleeping computer. A corresponding portable transceiver unit includes: a microphone to receive spoken voice commands from a user; a wireless transceiver to wirelessly communicate with a separate computer; and a motion sensor to detect a predetermined motion pattern at the portable transceiver unit. The wireless transceiver, in response to the motion sensor detecting the predetermined motion pattern of the transceiver, wirelessly transmits a wake signal to the computer.
