Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If conventional communication systems are used with zero-power terminals, then the terminals can achieve zero power consumption and small size, but the systems cannot accommodate terminals with varying capabilities and establish effective communication

Engineering Contradiction:

Improvepower consumptionVSAvoidcompatibility with different terminal types

Core Design Contradiction:

Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The network device dynamically adjusts its communication parameters and capability information based on the specific AMP device it is communicating with. The system transitions from a static, one-size-fits-all approach to a dynamic, adaptive approach where the network device can modify its behavior to match the capabilities of different zero-power terminal types.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of capability information transmission from the terminal side to the network device side. By having the network device send its capability information to the AMP device, the system enables parameter-based adaptation where communication modes, power levels, and protocols can be adjusted according to the specific capabilities of the zero-power terminal.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If zero-power terminals with diverse capabilities are supported, then adaptability improves, but the complexity of establishing connections and ensuring normal communication increases

Engineering Contradiction:

Improvesupport for diverse terminal capabilitiesVSAvoidconnection establishment complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent inverts the traditional communication setup by having the network device (rather than the terminal) send capability information to the AMP device. This inversion simplifies the connection establishment process because the network device already has centralized control and can proactively provide its capabilities, eliminating the need for complex capability negotiation protocols.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The capability information acts as an intermediary that facilitates communication between the network device and AMP device. By transmitting structured capability information, the system creates a common understanding layer that simplifies the matching process between network device capabilities and terminal requirements, reducing connection establishment complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If capability information is exchanged between network device and AMP device, then communication compatibility improves, but the amount of information transmission and processing increases

Engineering Contradiction:

Improvecommunication compatibilityVSAvoidinformation processing overhead

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent extracts only the essential capability information from the network device and transmits it to the AMP device. Rather than exchanging complete device profiles or extensive capability sets, the system identifies and transmits only the critical parameters needed for compatibility assessment, such as supported communication modes and power capabilities.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The network device performs preliminary preparation of capability information before actual communication begins. By pre-structuring and pre-transmitting capability information, the system avoids the need for complex real-time capability negotiation during connection establishment, reducing information processing overhead during critical communication phases.

Inventive Principle:

Principle #10Preliminary action
