Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wired connections are used to retrieve engine fault data, then data transmission reliability is improved, but ease of operation deteriorates due to the need for physical connections and cables

Engineering Contradiction:
Improvedata transmission reliabilityVSAvoidease of data access
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical wired connection system with a wireless communication system. The data acquisition unit transmits engine fault data wirelessly to external computing devices, eliminating the need for physical cables and connectors while maintaining data transmission capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a wireless communication intermediary (wireless transceiver system) between the data acquisition unit and external devices. This intermediary enables data transmission without direct physical contact, resolving the contradiction between reliability and ease of operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If wired connections are required for data retrieval, then data security is improved, but adaptability deteriorates in remote locations with limited network connectivity

Engineering Contradiction:
Improvedata securityVSAvoidadaptability to remote locations
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic connectivity options that adapt to the operational environment. The system can switch between wired and wireless connection modes depending on availability, with the wireless mode providing adaptability to remote locations while maintaining security protocols.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The data acquisition unit is designed with multi-functional communication capabilities, supporting both wired and wireless connection methods. This universality allows the system to adapt to different operational contexts, including remote locations with limited network infrastructure.

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

3Ease of operation

If only generic aircraft data is retrieved, then ease of operation is improved, but measurement precision deteriorates for specific engine fault diagnosis

Engineering Contradiction:
Improveease of data retrievalVSAvoidfault diagnosis precision
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent implements local quality by providing different data granularities for different needs. The system can retrieve both generic aircraft-level data for quick assessments and specific engine-component-level data for precise fault diagnosis, allowing maintenance personnel to access the appropriate level of detail based on the situation.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent segments the data retrieval system into multiple levels: generic aircraft data, system-level data, and component-specific engine data. This segmentation enables easy retrieval of high-level information while also providing access to detailed precision data when needed for specific fault diagnosis.

Inventive Principle:
Principle #1Segmentation

AI summary

A data transmission system and method for an engine (10) of an aircraft (100). Engine fault data indicative of at least one fault condition of the engine (10) is obtained at a computing device (102) provided on-board the aircraft (100). Sensor data associated with the at least one fault condition is retrieved based on the engine fault data. The engine fault data and the sensor data are transmitted, through a wireless connection (112), to an electronic device (110) external to the aircraft (100).
