Solution Overview

Problem

Existing communication systems in IoT devices face challenges in optimizing the activation of multiple communication modules, leading to high power consumption and interference due to simultaneous activation of modules using the same or similar frequency bands.

Innovation Solution

A communication apparatus with a communication controller that sequentially activates and deactivates communication modules based on predetermined cycles and times, minimizing interference and power consumption by setting specific active and inactive periods for each module, and adjusting activation orders based on usage patterns and relative positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple communication modules are activated simultaneously to support various communication methods, then communication versatility is improved, but power consumption increases and interference occurs between modules using the same frequency band

Engineering Contradiction:

Improvecommunication versatilityVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The communication controller activates communication modules periodically based on predetermined activation cycles and times rather than continuously. Each module is activated only when needed for specific communication tasks, allowing the system to maintain versatility while reducing overall power consumption by entering low-power states between activations.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system dynamically adjusts the activation state of communication modules based on real-time communication needs and usage patterns. The communication controller can flexibly switch modules between active and inactive states, optimizing power consumption while maintaining the capability to support multiple communication methods when required.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple communication modules are activated simultaneously to support various communication methods, then communication versatility is improved, but interference occurs between modules using the same frequency band

Engineering Contradiction:

Improvecommunication versatilityVSAvoidinterference

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

Communication modules are activated in periodic intervals rather than simultaneously, with each module operating during its designated time window. This temporal separation prevents frequency interference between modules while maintaining the system's ability to support multiple communication protocols through sequential activation.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The communication system is segmented into multiple independently controllable modules, each handling specific communication protocols. The communication controller manages these segmented modules separately, activating only the required module for each communication task, thereby avoiding interference while preserving overall communication versatility.

Inventive Principle:

Principle #1Segmentation

3Speed

If communication modules are activated continuously to ensure immediate communication availability, then communication responsiveness is improved, but power consumption increases

Engineering Contradiction:

Improvecommunication responsivenessVSAvoidpower consumption

Core Design Contradiction:

SpeedVSUse of energy by moving object

Solution Approach 1:

The communication controller preliminarily determines which communication modules need to be activated based on predicted communication requirements and usage patterns. By preparing and activating only the necessary modules in advance rather than keeping all modules continuously active, the system achieves responsive communication while minimizing power consumption.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The communication system incorporates self-service mechanisms where the communication controller automatically manages module activation based on detected communication needs. This eliminates the need for continuous manual monitoring while maintaining responsive communication availability, reducing power consumption through automated, demand-driven module activation.

Inventive Principle:

Principle #25Self-service
