Solution Overview

Problem

Existing surveillance systems and mobile apps fail to adequately capture audio recordings during conflicts, face storage limitations, and do not effectively comply with varying local recording laws, making it difficult for individuals to gather evidence and defend themselves legally.

Innovation Solution

A defense recorder system and mobile app that automatically records audio, manages storage, and complies with local recording laws by using GPS to determine jurisdictional rules, ensuring continuous recording in public areas and pausing in private areas, with cloud upload options to maintain access to recordings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing surveillance cameras and devices are used to record audio during conflicts, then recording capability is provided, but they fail to adequately capture audio and follow a person's actions

Engineering Contradiction:
Improveaudio recording capabilityVSAvoidability to follow person's actions
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system automatically determines the user's location using GPS, identifies applicable recording laws, and controls recording operations without manual intervention. The device serves itself by autonomously complying with legal requirements across different jurisdictions.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The recording system dynamically adjusts its operation based on real-time location data. As the user moves between jurisdictions with different recording laws, the system automatically adapts its recording behavior to comply with local regulations.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If hand-held portable recording devices are carried and used continuously, then recording availability is improved, but storage space is limited and manual management is required

Engineering Contradiction:
Improverecording availabilityVSAvoidstorage space
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The system automatically deletes older audio recordings when storage capacity is reached, maintaining only the most recent recordings. This automatic discarding mechanism eliminates the need for manual storage management while ensuring continuous recording capability.

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The device autonomously manages its own storage by automatically deleting old recordings when full, without requiring user intervention to monitor or clear storage space.

Inventive Principle:
Principle #25Self-service

3Reliability

If cloud storage is used to store recordings, then access to recordings is maintained, but system cost increases significantly

Engineering Contradiction:
Improveaccess to recordingsVSAvoidsystem cost
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the cloud storage component from the essential functionality, making it an optional feature rather than a requirement. The core recording and storage functions operate independently of cloud services, eliminating mandatory high costs while preserving optional cloud access for those who need it.

Inventive Principle:
Principle #2Taking out (Extraction)

4Reliability

If audio recording is performed continuously to comply with single party consent laws, then legal compliance is achieved, but storage is consumed faster and requires automatic deletion of oldest files

Engineering Contradiction:
Improvelegal complianceVSAvoidstorage consumption
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The system implements automatic deletion of the oldest audio recordings when storage capacity is reached, enabling continuous compliance with single-party consent laws while managing limited storage resources. This looping recording mode ensures legal compliance without manual intervention.

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The recording system operates in a periodic looping mode, continuously overwriting oldest recordings with new ones. This periodic deletion and replacement cycle maintains continuous recording capability while adhering to storage constraints and legal requirements.

Inventive Principle:
Principle #19Periodic action

5Ease of operation

If users manually manage recordings by stopping and starting recordings and identifying useless ones, then recording control is provided, but time is lost and user burden increases

Engineering Contradiction:
Improverecording controlVSAvoidmanual management time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system automatically controls recording operations based on real-time location data and applicable laws, eliminating the need for users to manually start or stop recordings. The device autonomously manages the entire recording process, saving user time and effort.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors the user's location and feeds this information back to automatically adjust recording operations. This feedback loop enables the device to autonomously comply with varying recording laws without manual user input.

Inventive Principle:
Principle #23Feedback

AI summary

A defense recorder system and mobile application-implemented process are disclosed. The defense recorder system and mobile application-implemented process combines GPS location to record in public areas when local laws state that audio recording is only legal in public areas. Single party consent states will not require the GPS function but will require the constant audio recording to be made in a loop, deleting the oldest of files automatically.
