Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Consumer audio devices like headphones lack the capability to create, maintain, and use secure data due to power and cost constraints, limiting their functionality and security.

Innovation Solution

Incorporating a timer and encryption member into headphones to manage and secure user data, including usage time and hearing profiles, preventing unauthorized access and tampering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If secure data management components (timer, encryption member) are added to headphones, then security and functionality are improved, but device complexity and cost increase

Engineering Contradiction:

ImprovesecurityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the timer and encryption member into a unified security system within the headphone device. These components work together as an integrated subsystem to manage secure data, including usage time tracking and hearing profile protection, rather than operating as separate independent modules.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The secure data management system serves multiple functions: it tracks usage time, protects hearing profiles, prevents unauthorized access, and manages device operation permissions. This multi-functional approach consolidates several security-related capabilities into a single integrated system, reducing overall complexity despite adding capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If secure data management components are added to headphones, then security is improved, but power consumption increases

Engineering Contradiction:

ImprovesecurityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The timer and encryption member perform security-related operations in advance, such as establishing encryption keys before data transmission and pre-calculating usage time limits. This preliminary action reduces the need for continuous power-intensive computations during normal operation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The secure data management system operates autonomously, with the timer continuously tracking usage time and the encryption member automatically protecting data without requiring constant user intervention or high-power processing. The system manages its own security functions efficiently, minimizing external power demands.

Inventive Principle:

Principle #25Self-service

AI summary

Presented here is an audio device, such as a headphone, that can create, maintain and use secure data. The secure data can include an amount of time that the user has used the audio device and/or an amount of time allocated to the user. When the amount of time the user has used the audio device exceeds the amount of time allocated to the user, the audio device can stop emitting the audio. The secure data can also include a hearing profile of the user, which ca uniquely identify the user. The secure data associated with the headphone can be encrypted to prevent tampering.
