Solution Overview

Problem

Existing data storage and processing systems in household automation and body sensors face challenges such as unauthorized data modification, unauthorized data sharing, and data deletion, particularly when sensitive data is transferred to cloud services without user consent or control.

Innovation Solution

A system comprising a filter component, a filter management device, and a memory unit that allows for real-time filtering and storage of data without pre-defined filter rules, enabling users to control data processing and transmission by analyzing and structuring data content before sending it to a backend, with options for anonymization, format conversion, and metadata management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If data is transferred to cloud services for processing, then data processing capability is improved, but user control and data security deteriorate

Engineering Contradiction:
Improvedata processing capabilityVSAvoiduser control
Core Design Contradiction:
PowerVSReliability

Solution Approach 1:

The system segments data processing into multiple stages: local filtering at the edge device, selective transmission to cloud, and targeted cloud processing. This segmentation allows maintaining user control through local decision-making while still utilizing cloud processing capabilities for specific data subsets that pass the filter criteria.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The filter component acts as an intermediary between local data sources and cloud services. It evaluates data against filter rules before transmission, serving as a mediator that protects user control while enabling cloud processing. The filter management device further mediates by dynamically configuring filter rules based on data characteristics.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If filter rules are predefined, then filtering efficiency is improved, but adaptability to new data types deteriorates

Engineering Contradiction:
Improvefiltering efficiencyVSAvoidadaptability to new data types
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The filter rules are made dynamic through the filter management device that can modify filter criteria based on analyzed data characteristics. The system transitions from static predefined rules to dynamic adaptive rules that evolve with new data types, maintaining both filtering efficiency and adaptability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The filter management device automatically analyzes data streams and configures appropriate filter rules without requiring manual intervention. This self-service capability allows the system to adapt to new data types autonomously while maintaining efficient filtering through automatically optimized rules.

Inventive Principle:
Principle #25Self-service

3Loss of information

If all data is transmitted to backend, then data availability is improved, but network bandwidth consumption and processing load deteriorate

Engineering Contradiction:
Improvedata availabilityVSAvoidnetwork bandwidth consumption
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

Instead of transmitting all data to the backend, the system applies partial action by selectively filtering and transmitting only relevant data subsets that match filter criteria. This reduces network bandwidth consumption and backend processing load while maintaining data availability for transmitted portions.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The filter component extracts and transmits only specific data elements that meet filter rules, leaving irrelevant data locally. This extraction approach minimizes network bandwidth consumption and backend processing requirements while ensuring availability of critical data subsets.

Inventive Principle:
Principle #2Taking out (Extraction)
