Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wiring methods are used to connect sensor arrays to data collection units, then reliable data transmission is achieved, but the garment becomes difficult to put on and take off
Solution Approach 1:
The sensor arrays are divided into modular units that can be independently attached and detached from the garment. Each sensor array unit connects to the data collection unit through simplified interfaces, allowing the garment to be easily put on and taken off while maintaining reliable data transmission through the modular connection system.
2Measurement precision
If complex sensor arrangements are integrated into the garment, then comprehensive data acquisition is achieved, but production costs increase significantly
Solution Approach 1:
The data collection unit is designed as a universal platform that can interface with multiple types of sensor arrays (temperature, humidity, motion, etc.). This multi-functional design allows comprehensive data acquisition across different physiological parameters while using a single standardized data collection unit, thereby reducing production costs through economies of scale and simplified manufacturing processes.
3Reliability
If multiple sensor arrays are connected via electrical cables, then stable electrical connection is achieved, but the garment design becomes overly complex
Solution Approach 1:
A flexible printed circuit board (FPC) is introduced as an intermediary component between the sensor arrays and the data collection unit. The FPC provides stable electrical connections through its conductive traces while maintaining flexibility to accommodate garment movements. This intermediary solution eliminates the need for bulky traditional electrical cables, thereby reducing garment design complexity while ensuring reliable electrical connectivity.

AI summary
The invention relates to clothing (10) in the form of a multisensor dress with several sensor arrangements (22a, 22b), in particular for detecting body postures and/or movements of a user of the clothing (10). Each sensor arrangement (22a, 22b) has at least one sensor, in particular in the form of an inertial movement unit. The sensor arrangements (22a, 22b) are connected, in particular in parallel to each other, to a data collection unit (28) via at least one bus line (24a, 24b). The bus line(s) (24a, 24b) can each have a carrier strip (26a) made of fabric. The electrical connection of the sensor arrangements (22a, 22b) to the respective bus line (24a, 24b) is preferably made by purely mechanically pressing the sensor arrangements (22a, 22b) onto the bus line (24a, 24b). A band and/or a pocket is preferably used for this purpose.The data collection unit (28) preferably has a storage means and/or a transmission means for the data measured by the sensor arrangements (22a, 22b), but no evaluation unit for this data.
