Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dedicated equipment is used to generate reference clock signals, then synchronization stability is improved, but system cost and complexity increase

Engineering Contradiction:

Improvesynchronization stabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The power distribution system performs multiple functions: it distributes electrical power to devices and simultaneously distributes a stable reference frequency signal derived from the power line frequency. This eliminates the need for separate dedicated reference signal generation equipment, reducing system complexity while maintaining synchronization stability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention combines the reference frequency signal distribution function with the existing power distribution infrastructure. By modulating the reference frequency onto the power line or deriving it from the power frequency, the system merges two functions (power delivery and reference signal distribution) into a single integrated system.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If dedicated equipment is wired to all components, then reference clock signal stability is improved, but scalability deteriorates

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The power distribution system serves as a universal platform that can simultaneously provide both power and reference frequency signals to any number of devices connected to it. When new devices are added to the power distribution network, they automatically receive both power and the stable reference frequency signal without requiring additional dedicated reference signal generation equipment.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system uses the existing power distribution infrastructure and its inherent frequency characteristics to provide the reference frequency signal. Instead of requiring external dedicated equipment to generate reference signals, the system leverages the stable frequency already present in the power line (or a frequency derived from it), making the existing infrastructure serve the additional function of reference signal provision.
