Solution Overview

Problem

Portable electronic devices face challenges in managing power consumption and processor activity efficiently, particularly in balancing user interaction and battery life, as existing modes either allow full functionality or restrict all interaction to conserve power.

Innovation Solution

The introduction of a second mode of operation that allows locked user interaction with specific limited user inputs, enabling users to interact with reduced functionality while minimizing power consumption and processor activity, distinct from the fully active or standby modes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the device operates in fully active mode to allow general user interaction with all functions, then user interaction capability is improved, but power consumption and processor activity increase

Engineering Contradiction:
Improveuser interaction capabilityVSAvoidpower consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent segments user interaction into two distinct modes: a first mode allowing general unlocked user interaction with full functionality, and a second mode allowing only specific limited user inputs. This segmentation enables the device to provide appropriate interaction levels based on user needs while consuming less power when full functionality is not required.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device dynamically switches between two operational modes based on user interaction requirements. The controller can transition from the first mode (full interaction) to the second mode (limited interaction) and vice versa, allowing the system to adapt its power consumption and interaction capabilities in real-time based on actual usage patterns.

Inventive Principle:
Principle #15Dynamics

2Use of energy by moving object

If the device enters standby mode to prevent user interaction and disable functionality, then power consumption is reduced, but user interaction capability is lost

Engineering Contradiction:
Improvepower consumptionVSAvoiduser interaction capability
Core Design Contradiction:
Use of energy by moving objectVSEase of operation

Solution Approach 1:

The patent implements a second mode that provides partial user interaction capability rather than complete interaction or complete restriction. This partial action mode allows specific limited user inputs (such as accepting or rejecting calls, viewing notifications) while maintaining reduced power consumption, avoiding the need to choose between full interaction and total standby.

Inventive Principle:
Principle #16Partial or excessive action

3Adaptability or versatility

If the device allows multiple applications to run simultaneously for full functionality, then application availability is improved, but processor activity and power consumption increase

Engineering Contradiction:
Improveapplication availabilityVSAvoidprocessor activity
Core Design Contradiction:
Adaptability or versatilityVSPower

Solution Approach 1:

The patent segments application availability based on operational mode. In the first mode, multiple applications can run with full functionality. In the second mode, only essential functions are available while maintaining reduced processor activity. This segmentation allows the system to provide appropriate application availability based on power constraints and user needs.

Inventive Principle:
Principle #1Segmentation
