Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the data driving device always operates to receive data, then data reception reliability is improved, but power consumption increases

Engineering Contradiction:

Improvedata reception reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic operation mode switching between low-power standby mode and active reception mode. The data driving device transitions from a static always-on state to a dynamic state that adjusts its operation level based on reception needs, thereby reducing power consumption while maintaining reliable data reception when required

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent employs periodic wake-up mechanisms where the data driving device periodically checks for incoming data or wakes up from standby mode at predetermined intervals. This periodic action allows the device to maintain readiness for data reception without continuously operating at full power, thus resolving the contradiction between reliability and power consumption

Inventive Principle:

Principle #19Periodic action

2Reliability

If the data processing device always operates to transmit data, then data transmission reliability is improved, but power consumption increases

Engineering Contradiction:

Improvedata transmission reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The data processing device dynamically adjusts its operation state between standby and active modes based on transmission requirements. By switching from continuous operation to on-demand operation, the system maintains transmission reliability when data needs to be sent while significantly reducing power consumption during idle periods

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements feedback mechanisms where the data processing device receives status information from the data driving device and adjusts its operation accordingly. This feedback loop ensures the transmission device only operates when necessary, maintaining reliability while optimizing power usage

Inventive Principle:

Principle #23Feedback

3Use of energy by moving object

If the device enters low-power mode frequently, then power consumption is reduced, but data reception responsiveness may deteriorate

Engineering Contradiction:

Improvepower consumptionVSAvoiddata reception responsiveness

Core Design Contradiction:

Use of energy by moving objectVSLoss of time

Solution Approach 1:

The patent implements preliminary wake-up checks and pre-positioning of reception circuits before actual data reception is needed. The device performs preliminary actions such as checking for incoming data signals or preparing reception buffers in advance, which reduces the time penalty associated with entering low-power mode while still achieving significant power savings

Inventive Principle:

Principle #10Preliminary action
