Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wireless communication is introduced between devices in a vehicle, then communication convenience is improved, but communication stability deteriorates due to interference from portable devices and metallic components

Engineering Contradiction:
Improvecommunication convenienceVSAvoidcommunication stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The communication band is divided into multiple segments or channels. The communication managing device allocates different communication bands to different wireless subsystems, preventing interference between them and stabilizing communication despite the presence of portable devices and metallic components in the vehicle environment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The communication managing device dynamically monitors wireless communication status and adjusts communication band allocations in real-time based on detected interference conditions. This dynamic adaptation allows the system to maintain stable communication by reallocating bands when interference from portable devices or metallic components is detected.

Inventive Principle:
Principle #15Dynamics

2Reliability

If communication band allocation is changed to improve communication status, then communication stability is improved, but device complexity increases

Engineering Contradiction:
Improvecommunication stabilityVSAvoidcommunication management complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The communication managing device performs multiple functions: it monitors wireless communication status, detects interference conditions, manages communication band allocations, and controls wireless subsystems. By consolidating these functions in a single device, the system achieves improved communication stability without proportionally increasing overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The communication managing device automatically monitors communication status and adjusts band allocations without requiring manual intervention. The system self-regulates by detecting interference conditions and reallocating bands autonomously, reducing the complexity of manual configuration and management.

Inventive Principle:
Principle #25Self-service

AI summary

A communication managing device includes a monitoring unit that monitors wireless communication between a plurality of communication devices performing the wireless communication in a vehicle on the basis of a common communication standard and a communication status improving unit that performs a countermeasure for improving a communication status of the wireless communication on the basis of a result of the monitoring. The communication managing device may further include transfer means that sends a message to an occupant in the vehicle, and the communication status improving unit may improve the communication status of the wireless communication by sending a message for requesting for avoiding wireless communication based on the communication standard in a portable device to the occupant via the transfer means.
