Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional electronic security systems use complex wiring and multiple connection points to achieve desired functionality, then the system can perform required security functions, but the installation and reconfiguration become time-consuming and require electrical expertise

Engineering Contradiction:
Improvesystem functionalityVSAvoidinstallation ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent combines power delivery and data communication into a single two-wire interface. The controller communicates with security devices (locks, alarms, access control readers) through the same wires that provide electrical power, eliminating the need for separate communication wiring and reducing installation complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The two-wire interface serves multiple functions simultaneously: it provides electrical power to devices, carries bidirectional communication signals, and enables configuration and monitoring. This multi-functional approach replaces traditional separate wiring for power, data, and control.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If conventional electronic security systems use specialized hardware components with many wires or connection points, then the system can achieve desired security functionality, but the system complexity increases and requires hardware expertise for configuration

Engineering Contradiction:
Improvesecurity functionalityVSAvoidwiring complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges power delivery and data communication into a single two-wire interface. The controller communicates with security devices (locks, alarms, access control readers) through the same wires that provide electrical power, eliminating the need for separate communication wiring and reducing installation complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces complex physical wiring mechanisms with a simplified two-wire interface that uses electrical signals for both power and communication. This substitution eliminates the need for multiple physical connections and reduces mechanical complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If conventional electronic security systems are reconfigured to meet changing needs, then the system can adapt to new requirements, but the reconfiguration process requires understanding and reworking of circuitry by electrical experts

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements a dynamic configuration capability where the controller can programmatically reconfigure security devices through the two-wire interface. Configuration changes are made via software commands rather than physical wiring modifications, allowing rapid adaptation to changing security requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent replaces complex physical wiring mechanisms with a simplified two-wire interface that uses electrical signals for both power and communication. This substitution eliminates the need for multiple physical connections and reduces mechanical complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
