Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wired video surveillance systems are used, then system reliability and data security are improved, but installation complexity and cost increase

Engineering Contradiction:

Improvedata securityVSAvoidinstallation complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces wired mechanical connections with wireless communication technology. The video surveillance system uses wireless transmitters in capture devices to transmit video signals and control data without physical cables, eliminating installation complexity while maintaining system reliability through encrypted wireless protocols and authentication mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a wireless communication intermediary layer between capture devices and recording devices. This intermediary uses standardized wireless protocols to bridge the connection, reducing installation complexity while maintaining security through protocol-level encryption and authentication handshakes.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If wireless video surveillance systems are implemented, then installation ease and remote access capability are improved, but security against interception deteriorates

Engineering Contradiction:

Improveinstallation easeVSAvoidwireless interception vulnerability

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary anti-action by implementing pre-encryption of video data and control signals before wireless transmission. Authentication protocols are executed in advance to verify device identities, and security credentials are exchanged beforehand to prevent unauthorized interception and access.

Inventive Principle:

Principle #9Preliminary anti-action

Solution Approach 2:

The patent changes the parameter of wireless signal transmission by using dynamic encryption keys and variable modulation schemes. The system adjusts transmission parameters including encryption strength, authentication methods, and signal modulation to balance security requirements with wireless communication needs.

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If remote access capability is added to surveillance systems, then user convenience is improved, but system vulnerability to Internet attacks increases

Engineering Contradiction:

Improveremote access convenienceVSAvoidInternet attack vulnerability

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a remote server computer as an intermediary between the wireless surveillance system and Internet-connected user devices. This intermediary provides a secure gateway that authenticates users, encrypts data streams, and manages remote access permissions, allowing convenient remote viewing while protecting the core surveillance system from direct Internet exposure.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the surveillance system into isolated functional modules with controlled access points. The remote access function is separated from the core recording and capture functions, allowing remote viewing capability while maintaining security boundaries that prevent Internet attacks from compromising the entire system.

Inventive Principle:

Principle #1Segmentation

4Adaptability or versatility

If external removable storage is implemented, then data portability and backup capability are improved, but system complexity increases

Engineering Contradiction:

Improvedata portabilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements universal data storage interfaces that support multiple storage media types including removable external drives, cloud storage, and local digital video recorders. The system uses standardized connection protocols and file formats that work across different storage devices, providing data portability and backup capability without requiring separate systems for each storage method.

Inventive Principle:

Principle #6Universality (Multi-functionality)
