Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the antenna beam is frequently adjusted to improve data transmission quality, then the communication quality is improved, but the power consumption increases

Engineering Contradiction:

Improvedata transmission qualityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The device performs preliminary actions by storing historical transmission results and environmental information in a storage unit before actual communication occurs. The control unit references this pre-stored data to determine optimal antenna settings in advance, avoiding the need for frequent real-time adjustments and reducing power consumption while maintaining transmission quality.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system performs self-service by automatically learning from its own historical transmission results and environmental conditions. The control unit uses stored historical data to autonomously determine optimal antenna settings without requiring continuous external intervention or frequent adjustments, thereby reducing power consumption while maintaining reliable communication.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If the antenna beam is adjusted multiple times to select different propagation paths, then the adaptability to communication conditions is improved, but the power consumption increases

Engineering Contradiction:

Improveadaptability to communication conditionsVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The device performs preliminary actions by storing historical transmission results and environmental information in a storage unit before actual communication occurs. The control unit references this pre-stored data to determine optimal antenna settings in advance, avoiding the need for frequent real-time adjustments and reducing power consumption while maintaining transmission quality.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system changes parameters by storing historical antenna settings and transmission results, then selecting from pre-stored parameter combinations rather than continuously adjusting. This allows the system to adapt to different communication conditions by referencing historical data while avoiding the power consumption associated with frequent real-time parameter changes.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If the antenna characteristic control mode is changed frequently, then the data transmission quality is improved, but the processing time increases

Engineering Contradiction:

Improvedata transmission qualityVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The device performs preliminary actions by storing historical transmission results and environmental information in a storage unit before actual communication occurs. The control unit references this pre-stored data to determine optimal antenna settings in advance, avoiding the need for frequent real-time adjustments and reducing power consumption while maintaining transmission quality.

Inventive Principle:

AI summary

An information communication device includes a transmission unit that wirelessly transmits a signal including data to a communication partner device via a transmission antenna, a reception unit that receives, via a reception antenna, an Ack signal wirelessly transmitted from the communication partner device; and a control unit that changes an antenna characteristic control mode of the transmission antenna, based on a reception state of the Ack signal received by the reception unit.
