Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the terminal continuously monitors control channels to ensure reliable communication, then communication reliability is improved, but power consumption increases

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The terminal is segmented into two functional parts: a low-power wakeup receiver that continuously monitors for wake-up signals, and a main receiver that remains dormant and activates only when needed. This segmentation allows the terminal to maintain communication reliability through continuous monitoring while significantly reducing power consumption by keeping the power-hungry main receiver off most of the time.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The terminal dynamically adjusts its reception state based on incoming signals. The wakeup receiver operates in a low-power state continuously, but the main receiver transitions from a dormant state to an active state only when a wake-up signal is detected. This dynamic operation allows the system to maintain reliability while optimizing power consumption according to actual communication needs.

Inventive Principle:

Principle #15Dynamics

2Difficulty of detecting and measuring

If the terminal activates the main receiver frequently to check for signals, then signal detection capability is improved, but battery life deteriorates

Engineering Contradiction:

Improvesignal detection capabilityVSAvoidbattery life

Core Design Contradiction:

Difficulty of detecting and measuringVSDuration of action of moving object

Solution Approach 1:

The reception function is segmented between a wakeup receiver with basic signal detection capability that operates continuously at low power, and a main receiver with full signal processing capability that operates intermittently. This segmentation enables the terminal to maintain signal detection capability through the always-on wakeup receiver while preserving battery life by limiting main receiver activation to essential moments only.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of continuous operation of the main receiver, the system employs periodic activation triggered by wake-up signals. The wakeup receiver continuously monitors for periodic wake-up opportunities, and the main receiver is activated periodically only when necessary, dramatically reducing overall power consumption while maintaining adequate signal detection capability.

Inventive Principle:

Principle #19Periodic action
