Problem

Establishing effective communication between network devices and zero-power terminals with diverse capabilities is challenging due to their unique power requirements and varying types, which conventional systems struggle to accommodate.

Innovation Solution

The network device sends capability information to an ambient power (AMP) device, enabling the AMP device to select an appropriate network device for connection, ensuring normal communication by utilizing power harvesting, backscattering, and low-power technologies.

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 extremely low cost and zero power consumption, but the systems cannot accommodate diverse terminal capabilities and establish effective communication

Engineering Contradiction:
Improvepower consumptionVSAvoidcapability compatibility
Core Design Contradiction:
Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The patent applies parameter changes by introducing capability information exchange between network devices and AMP devices. The network device transmits its capability parameters (such as supported communication modes, power levels, and technical specifications) to the AMP device, enabling the system to adapt to diverse terminal capabilities while maintaining zero-power operation. This parameter-based adaptation resolves the contradiction by allowing the system to configure communication according to specific device capabilities without requiring active power consumption for capability negotiation.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements preliminary action by having the network device proactively send its capability information to the AMP device before communication begins. This advance information provision allows the AMP device to pre-configure the communication parameters and select appropriate communication modes based on the network device's capabilities, ensuring compatibility is established beforehand rather than during active communication, thus maintaining zero-power consumption while achieving capability adaptation.

Inventive Principle:
Principle #10Preliminary action

2Ease of manufacture

If zero-power terminals are deployed widely, then cost and power consumption are reduced, but connection establishment and normal communication become difficult due to capability differences

Engineering Contradiction:
Improvedeployment costVSAvoidcommunication reliability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent applies feedback by establishing a capability information feedback mechanism where the network device provides its capability status to the AMP device. This feedback loop enables the AMP device to make informed decisions about connection establishment and communication mode selection based on the network device's actual capabilities. The feedback ensures that communication parameters are appropriately matched to device capabilities, thereby maintaining communication reliability despite the widespread deployment of low-cost zero-power terminals.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If capability information is exchanged between network devices and AMP devices, then appropriate connections can be established, but additional communication overhead is introduced

Engineering Contradiction:
Improveconnection compatibilityVSAvoidcommunication overhead
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent applies the extraction principle by isolating the capability information exchange as a separate, preliminary communication phase distinct from the main data communication process. The capability information is extracted and transmitted beforehand, allowing the subsequent communication to proceed efficiently without repeated capability negotiations. This separation minimizes the impact of capability exchange overhead on overall communication efficiency while ensuring connection compatibility is established upfront.

Inventive Principle:
Principle #2Taking out (Extraction)
