Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a system only generates sensor signals representing orientation, then the device structure remains simple, but the number of possible applications is limited
Solution Approach 1:
The system is designed to perform multiple functions: it generates sensor signals representing orientation and also compares these signals with reference signals to interpret orientation. This multi-functionality allows the same system to support diverse applications such as controlling multimedia equipment based on device orientation, providing navigation assistance, or triggering specific actions when certain orientations are detected, thereby increasing adaptability without requiring multiple separate systems
Solution Approach 2:
The system is divided into separate functional modules: a generating device that produces sensor signals and a comparing device that interprets these signals by comparing them with reference signals. This segmentation allows each module to be optimized independently while maintaining overall system versatility, resolving the contradiction between application diversity and structural complexity
2Adaptability or versatility
If sensor signals are continuously processed and interpreted, then application versatility improves, but power consumption increases
Solution Approach 1:
The comparing device can be configured to process and interpret sensor signals periodically or only when specific conditions are met, rather than continuously. This allows the system to maintain application versatility by being ready to interpret orientation data when needed, while reducing power consumption by entering low-power states between processing cycles or when orientation changes are not detected

AI summary
Systems comprising generating devices comprising sensors for generating sensor signals representing orientations of the generating devices are provided with comparing devices comprising comparators for comparing the sensor signals with reference signals for interpreting the orientations, to increase the number of possible applications. The generating devices and the comparing devices may form parts of one apparatus or of different apparatuses and then communicate wiredly or wirelessly via radio or infrared. Reference sensors for generating the reference signals and/or reference memories for storing the reference signals may be located in the comparing devices and/or in sources and then communicate wiredly or wirelessly via radio or infrared. Further comparators in the comparing devices may introduce adjustable sensitivities.
