Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the automotive industry's Research and Development (R&D) and Verification and Validation (VV) processes, the frequent change of testing devices during test phases leads to errors due to incorrect wiring and configuration of test sensors and evaluation units, increasing the likelihood of errors and inefficiency in acquiring and processing measured values.
Innovation Solution
A measuring module with a test sensor and communications device is integrated into the test object, allowing for wireless transmission of measured values to various evaluation units, eliminating the need for repeated sensor arrangement and configuration, and enabling consistent data acquisition across different testing devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If test sensors are arranged on the test object for each testing device change, then the testing device can be changed between different test phases, but the wiring and configuration errors increase
Solution Approach 1:
The test sensors are extracted from the testing device and integrated into the test object itself as a measuring module. This separation means the sensors remain fixed on the test object while the testing device can be changed without affecting the sensor arrangement, thereby maintaining wiring correctness while enabling device changeability.
Solution Approach 2:
The test sensors are pre-installed on the test object during manufacturing, before the testing device is changed. This preliminary arrangement eliminates the need for re-wiring when testing devices are changed between test phases, ensuring consistent wiring correctness across different testing devices.
2Adaptability or versatility
If test sensors are arranged on the test object for each testing device change, then different testing devices can be used, but the configuration time increases
Solution Approach 1:
The measuring module with test sensors is extracted from the testing device and integrated into the test object. This allows the test object to be tested on different testing devices without reconfiguration, as the sensors remain fixed on the test object and automatically interface with the respective testing devices.
Solution Approach 2:
The measuring module on the test object serves multiple testing devices universally. The same sensor arrangement can be used across different testing devices for various test phases, eliminating the need for reconfiguration and reducing time loss when switching between different testing devices.
3Adaptability or versatility
If test sensors are arranged on the test object for each testing device change, then new testing devices can be used, but the risk of measurement errors increases
Solution Approach 1:
The test sensors are extracted from the testing device and permanently integrated into the test object as a measuring module. This ensures that the same sensors are used across all test phases and different testing devices, eliminating measurement errors that would arise from sensor replacement and ensuring consistent measurement accuracy.
Solution Approach 2:
The test sensors are preliminarily installed on the test object during manufacturing with correct positioning and calibration. This preliminary action ensures that when the test object is used with different testing devices, the measurement accuracy is maintained without the risks associated with re-arranging sensors.
