Solution Overview

Problem

Mobile communication devices face challenges in secure charging, as environments for recharging are often insecure, leading to concerns about theft and unauthorized use, especially given the time-consuming nature of recharging and the need for continuous user presence to prevent device removal.

Innovation Solution

A secure mobile device charger equipped with a biometric sensor that reads biometric input data and a switch to prevent unauthorized charging, allowing only authorized users to access power, using a combination of a body housing battery charging elements, a power connector, and a mobile device connector.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users charge mobile devices in public environments, then charging accessibility is improved, but security against theft and unauthorized use deteriorates

Engineering Contradiction:

Improvecharging accessibilityVSAvoidsecurity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent introduces an intermediary authentication mechanism (biometric sensor and authorization system) between the charging device and the mobile device. This intermediary verifies user identity and controls power delivery, allowing public charging accessibility while maintaining security through automated authentication. The charging device acts as a mediator that enables unauthorized devices to be rejected and authorized users to be identified without requiring physical presence.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If users remain physically present to monitor charging devices, then security is improved, but convenience and mobility deteriorate

Engineering Contradiction:

ImprovesecurityVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The charging device performs self-service authentication and monitoring functions through integrated biometric sensors and authorization systems. The device automatically verifies user identity, controls power delivery, and prevents unauthorized access without requiring continuous human supervision. This automation maintains security while freeing users from the burden of physical presence, allowing them to charge devices and move freely.

Inventive Principle:

Principle #25Self-service

3Duration of action of moving object

If charging time is extended, then battery capacity is improved, but vulnerability to theft and unauthorized use increases

Engineering Contradiction:

Improvecharging timeVSAvoidtheft risk

Core Design Contradiction:

Duration of action of moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent implements preliminary authentication action before charging begins. The biometric sensor verifies user identity and the authorization system grants permission before power delivery is activated. This preliminary security measure ensures that even during extended charging periods, only authorized users can access their devices, preventing theft and unauthorized use while allowing full charging duration.

Inventive Principle:

Principle #10Preliminary action
