Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an atmospheric pressure sensor is integrated into a portable object like a wristwatch, then the device can provide altitude indication, but meteorological variations cause distorted altitude readings
Solution Approach 1:
The invention segments the measurement functions by introducing a clutch mechanism that separates the barometric trend display function from the altitude indication function. The atmospheric pressure sensor can be coupled to either the altitude display device or the barometric trend display device, but not both simultaneously, allowing independent optimization of each measurement function and eliminating the harmful effect of meteorological variations on altitude readings.
2Measurement precision
If a barometric device is associated with an altimetric device to correct altitude indication, then altitude accuracy improves, but the device dimensions increase making it unsuitable for portable objects
Solution Approach 1:
The invention makes the atmospheric pressure sensor universal by enabling it to serve multiple functions through the clutch mechanism. The same sensor can be coupled to different display devices depending on the selected function (altitude indication or barometric trend display), eliminating the need for separate dedicated sensors for each function and thus avoiding increased device volume.
3Loss of information
If the atmospheric pressure sensor is continuously connected to the barometric trend display device, then meteorological trend indication is provided, but altitude indication becomes erratic when user changes location
Solution Approach 1:
The invention introduces dynamic reconfigurability through the clutch mechanism, allowing the user to switch between different operational modes (altitude indication mode or barometric trend display mode). This dynamic switching enables the system to adapt to different usage scenarios, providing stable altitude readings when needed and meteorological trend information when the user remains stationary.
