Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

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

Engineering Contradiction:

Improvesystem 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 and receivers to transmit video signals and control data without physical cables, eliminating the need for complex wiring installation while maintaining system functionality and security through encrypted wireless protocols

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If wireless video surveillance systems are implemented, then installation ease and cost are improved, but security against interception worsens

Engineering Contradiction:

Improveinstallation easeVSAvoidsecurity against interception

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent implements security measures by changing the parameters of wireless transmission, including using encrypted communication protocols, authentication mechanisms, and secure key exchange algorithms. These parameter changes ensure that wireless video signals and control data are protected from interception and unauthorized access while maintaining the ease of wireless installation

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If remote access capabilities are added, then user convenience is improved, but system vulnerability to unauthorized access increases

Engineering Contradiction:

Improveremote access convenienceVSAvoidunauthorized access risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary authentication mechanism for remote access. A secure authentication server or gateway acts as an intermediary between remote users and the surveillance system, verifying user credentials and authorizing access requests. This intermediary layer enables convenient remote access while protecting the system from unauthorized entry through multi-factor authentication and access control protocols

Inventive Principle:

Principle #24Intermediary (Mediator)
