Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic system is closely integrated or incorporated in the vehicle component, then the data recording capability is improved, but the ease of repair and data retrieval deteriorates
Solution Approach 1:
The system divides data storage into two separate components: an active electronic device for data recording and a passive data storage medium for data retention. This segmentation allows the passive medium to be remotely interrogated without requiring extraction of the integrated electronic system, thus resolving the contradiction between integration and ease of repair.
Solution Approach 2:
The passive data storage medium acts as an intermediary between the integrated electronic system and the remote interrogation system. It receives data from the electronic device and can be remotely read without physical extraction, enabling data retrieval while maintaining system integration.
2Ease of operation
If the electronic system uses an active power supply, then the data transmission capability is improved, but the reliability deteriorates when power supply fails or is exhausted
Solution Approach 1:
The system creates a copy of the data in a passive storage medium that does not require power to maintain data integrity. While the active electronic device transmits data using power, the passive medium preserves a copy that can be remotely interrogated even when the power supply fails, ensuring data accessibility.
Solution Approach 2:
The passive data storage medium serves as a backup mechanism that cushions against power supply failures. By continuously receiving and storing data from the active device, it ensures data is preserved and accessible even when the active system fails due to power exhaustion.
3Volume of moving object
If the electronic system is highly integrated in the vehicle component, then the compactness is improved, but the risk of simultaneous damage to both recording device and storage medium increases
Solution Approach 1:
By separating the electronic recording device from the passive data storage medium, the system reduces the volume of the active electronic components while maintaining data storage capability. The passive medium can be remotely accessed without physical proximity, effectively reducing the vulnerable integrated volume and the risk of simultaneous damage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables reliable data retrieval from embedded systems without physical extraction, reducing damage risks and simplifying the process, especially in integrated systems like aircraft tires, by using remote power and communication methods.
Implementation Method 1
The passive nature of the medium enables all the drawbacks of the power supply system of the electronic device to be overcome... the passive storage medium is adapted to be remotely powered by a remote interrogation system. This remote power supply is provided, for example, by the incident radiation from a data reader.
