Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If mobile devices access remote services to support multiple applications, then device functionality and versatility are improved, but security risks and data compromise concerns increase

Engineering Contradiction:

Improvedevice functionalityVSAvoidsecurity risks

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary authentication and activation before allowing remote service access. An activation record is created and stored on the mobile device prior to establishing any remote communications, ensuring that security verification occurs in advance rather than during data transmission.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces an activation record as an intermediary security element that mediates between the mobile device and remote services. This activation record, containing authenticated device information, serves as a trusted intermediary that enables secure communication without exposing sensitive data during transmission.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If sensitive data is transmitted over network connections for remote service access, then device adaptability is improved, but data security and confidentiality are compromised

Engineering Contradiction:

Improveremote service accessVSAvoiddata confidentiality

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The system extracts sensitive device information into a pre-authenticated activation record that is stored locally on the mobile device. This extraction eliminates the need to transmit sensitive data over network connections during remote service access, as the activation record has already been authenticated in advance.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Sensitive authentication data is processed and stored in an activated state before any remote service communications occur. The activation process completes all necessary security verifications beforehand, allowing subsequent remote access to proceed without transmitting sensitive information.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If activation records are digitally signed and authenticated, then security is improved, but processing time and activation complexity increase

Engineering Contradiction:

Improveauthentication securityVSAvoidactivation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The digital signature and authentication process is performed as a preliminary one-time action during device activation. Once the activation record is signed and authenticated, this security verification stands for all subsequent remote service accesses, eliminating the need for repeated authentication overhead during normal operations.

Inventive Principle:

Principle #10Preliminary action
