Wearable Scene Monitor Backup for Emergency Evidence Capture

Solution Overview

Problem

Existing personal safety systems face challenges in securely storing ambient environment data during emergencies, as attackers can easily destroy the device before data is uploaded to a remote server, and continuous data transmission to the cloud is battery-intensive and costly.

Innovation Solution

A personal safety apparatus that includes a mobile computing device and a wearable scene monitor, which continuously stores a first plurality of data locally and transmits a copy to the mobile device, ensuring a backup is available even if the apparatus is damaged, and also transmits a second plurality of data to a remote server for secure storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If data is continuously transmitted to a remote server, then data security and backup reliability are improved, but battery power consumption and data transmission costs increase

Engineering Contradiction:

Improvedata backup reliabilityVSAvoidbattery power consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary actions by continuously storing data locally in the wearable device's memory and maintaining a backup copy on the mobile computing device before any emergency occurs. This preliminary data preparation ensures that when an emergency happens, data can be immediately accessed from local storage without requiring continuous transmission to the remote server, thus reducing battery consumption while maintaining backup reliability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The invention creates multiple copies of data at different locations: the primary copy is stored in the wearable device's memory, a secondary copy is maintained on the mobile computing device, and a tertiary copy is available on the remote server. This copying strategy allows the system to maintain data backup reliability through redundancy while reducing the need for continuous transmission, as local copies can be accessed immediately when needed.

Inventive Principle:

Principle #26Copying

2Reliability

If data is continuously transmitted to a remote server, then data security and backup reliability are improved, but data transmission costs increase

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The system performs preliminary actions by continuously storing data locally in the wearable device's memory and maintaining a backup copy on the mobile computing device before any emergency occurs. This preliminary data preparation ensures that when an emergency happens, data can be immediately accessed from local storage without requiring continuous transmission to the remote server, thus reducing battery consumption while maintaining backup reliability.

3Weight of moving object

If the device is designed to be lightweight and portable, then ease of wear and user convenience are improved, but data storage capacity and processing power are reduced

Engineering Contradiction:

Improvedevice weightVSAvoiddata storage capacity

Core Design Contradiction:

Weight of moving objectVSQuantity of substance

Solution Approach 1:

The system segments data storage across multiple devices: the lightweight wearable device stores only essential data locally, while the mobile computing device (smartphone or tablet) stores additional data copies. This segmentation allows the wearable device to remain lightweight with minimal storage requirements, while still providing comprehensive data backup capability through the larger storage capacity of the mobile device.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention adds a dimensional aspect to data storage by utilizing the mobile computing device as an external storage dimension. Instead of requiring the wearable device to have large internal storage capacity, the system leverages the mobile device's storage capacity in another dimension (external connectivity), thereby maintaining the lightweight design of the wearable device while providing sufficient data storage capacity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
