Solution Overview

Problem

Existing wearable articles face challenges in efficiently and securely transferring power to other electronic apparatuses, particularly in ensuring power transfer only when authorized and when the wearable article has sufficient charge, while also allowing for wireless and secure power transmission.

Innovation Solution

A wearable article equipped with a processor that determines a power transfer condition, including authorization and charge levels, and uses a power transmitter to wirelessly transfer power via inductive or electromagnetic means, with a communicator for data exchange and an interface element for secure mechanical coupling, enabling power transfer to external apparatuses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the wearable article continuously transfers power to external apparatuses, then the power sharing capability is improved, but the wearable article's own charge depletes too quickly

Engineering Contradiction:

Improvepower sharing capabilityVSAvoidwearable article charge duration

Core Design Contradiction:

Adaptability or versatilityVSDuration of action of moving object

Solution Approach 1:

The processor performs preliminary assessment of power transfer conditions before initiating power transfer. It evaluates the power source charge level against threshold values and determines authorization status in advance, ensuring power transfer only occurs when appropriate conditions are met, thus preventing premature charge depletion

Inventive Principle:

Principle #10Preliminary action

2Productivity

If the wearable article transfers power without checking authorization, then the power transfer speed is improved, but unauthorized devices may receive power

Engineering Contradiction:

Improvepower transfer speedVSAvoidauthorized power transfer

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system performs preliminary authorization verification through the communicator before initiating power transfer. The processor checks whether the external apparatus is authorized to receive power in advance, and only proceeds with power transfer when authorization is confirmed, ensuring security while maintaining efficient power transfer

Inventive Principle:

Principle #10Preliminary action

3Reliability

If the wearable article checks power transfer conditions before transferring power, then the charge management is improved, but the power transfer response time increases

Engineering Contradiction:

Improvecharge managementVSAvoidpower transfer response time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The processor continuously monitors and preliminarily assesses power transfer conditions including charge levels and authorization status in the background. When a power transfer request occurs, the pre-evaluated conditions enable rapid decision-making, minimizing response time while maintaining reliable charge management

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where the processor continuously monitors power source charge levels and adjusts power transfer decisions based on real-time condition assessments. This feedback loop ensures reliable charge management by preventing power transfer when charge levels are insufficient

Inventive Principle:

Principle #23Feedback
