Solution Overview

Problem

Existing corded and cordless input devices, such as mice and keyboards, experience latency when transitioning from a low-power state to an active state, leading to delayed input recognition.

Innovation Solution

The implementation of a power management system that detects the approach of a user's hand and initiates a power-on sequence, allowing the input device to be fully operational by the time the hand touches the device, thereby eliminating latency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the input device enters a low-power state to save battery power, then energy consumption is reduced, but response latency increases when the user needs to use the device

Engineering Contradiction:
Improvebattery power consumptionVSAvoidresponse latency
Core Design Contradiction:
Use of energy by moving objectVSLoss of time

Solution Approach 1:

The system performs preliminary action by detecting the user's hand approach and initiating the power-on sequence before the user actually needs to use the device. The machine learning model predicts the user's intent based on hand movement patterns, allowing the device to wake up in advance and eliminate latency while still maintaining low-power state for extended periods.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from the machine learning model that analyzes hand approach patterns to dynamically adjust power management decisions. The model continuously learns from user behavior and provides feedback to optimize the balance between power consumption and response time, improving the prediction accuracy over time.

Inventive Principle:
Principle #23Feedback

2Speed

If the input device remains in active state to ensure immediate response, then response latency is reduced, but energy consumption increases

Engineering Contradiction:
Improveresponse speedVSAvoidbattery power consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The system activates components in advance based on predicted user intent. The machine learning model detects hand approach patterns and triggers the power-on sequence before the user makes contact, ensuring immediate response when needed while avoiding continuous active state that would drain battery.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts its power state based on real-time predictions from the machine learning model. Instead of static power management, the device transitions between low-power and active states dynamically, optimizing the balance between response speed and energy consumption based on actual user behavior patterns.

Inventive Principle:
Principle #15Dynamics
