Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple separate controllers and power supplies are connected via individual cables to the control panel, then each device can be controlled independently, but the number of cables and connection steps increases significantly

Engineering Contradiction:
Improveindependent device controlVSAvoidnumber of cables and connection steps
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate controllers (first controller for standard communication, second controller for safety communication) and power supply units into a single integrated control panel that interfaces with devices through a single LAN cable, merging multiple functions into one unified system

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The control panel is designed as a multi-functional device that simultaneously performs standard communication, safety communication, and power supply functions through a single LAN terminal, allowing one component to serve multiple purposes

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

2Reliability

If the control panel includes dedicated terminals for various cables connected to multiple devices, then all devices can be connected reliably, but the control panel size increases

Engineering Contradiction:
Improvedevice connection reliabilityVSAvoidcontrol panel size
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The LAN terminal serves multiple functions simultaneously - it provides both data communication pathways and power supply connection points, eliminating the need for separate dedicated terminals for each function and reducing overall panel size

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

3Reliability

If separate power supply connections are made for each device, then power can be supplied reliably to all devices, but the number of cables and installation steps increases

Engineering Contradiction:
Improvepower supply reliabilityVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The power supply function is merged with the communication interface through the LAN cable connection, allowing power to be transmitted along with data through the same cable infrastructure, thereby reducing installation steps and time

Inventive Principle:
Principle #5Merging (Combining)
