Solution Overview

Problem

Users often forget to adjust their device settings in contexts where it is necessary or polite to do so, such as during flights or performances, leading to non-compliance with rules and policies.

Innovation Solution

A system that automatically adjusts user device settings by determining the user's attendance at an event, requesting encryption information, receiving encrypted commands, and decrypting them using device-specific keys to change settings like airplane mode or silent mode, while ensuring user control and privacy through permissions and cryptography.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If automatic setting adjustment is implemented, then compliance with event rules is improved, but device security and user control may be compromised

Engineering Contradiction:

Improvecompliance with event rulesVSAvoidrisk to device security and user control

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces encrypted command signals as an intermediary mechanism between the external environment and device settings. These signals are transmitted through wireless communication but require decryption using device-specific keys stored in secure storage, acting as a mediator that enables automatic adjustment while maintaining security barriers

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary actions by pre-storing encryption keys in secure storage and pre-configuring the application to recognize event contexts. When an event is detected, the decryption and setting adjustment processes are already prepared, enabling rapid compliant response without compromising security protocols

Inventive Principle:

Principle #10Preliminary action

2Reliability

If encryption information is stored on the device, then secure automatic adjustment is enabled, but device storage and processing requirements increase

Engineering Contradiction:

Improvesecure automatic adjustmentVSAvoidstorage and processing requirements

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts only the essential encryption keys and stores them in the device's secure storage, separating the critical security elements from the full encryption system. This extraction approach enables secure automatic adjustment while minimizing the storage burden and processing complexity on the mobile device

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system changes the parameter of encryption implementation by using pre-stored keys rather than performing full encryption/decryption operations. This parameter change reduces the computational complexity and storage requirements while maintaining the security necessary for reliable automatic setting adjustment

Inventive Principle:

Principle #35Parameter changes
