Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a sensor surface is divided into numerous sensor surface sections in longitudinal and transverse directions, then measurement precision of force and pressure distribution is improved, but device complexity increases
Solution Approach 1:
The sensor surface is divided into multiple sensor surface sections in both longitudinal and transverse directions, with each section containing force sensors. This segmentation enables high-resolution measurement of force and pressure distribution across the gliding board surface, directly resolving the measurement precision requirement while managing complexity through modular sensor arrangement.
Solution Approach 2:
The sensor surface is tilted relative to the longitudinal axis by means of a tilting device, adding a dimensional aspect to the measurement system. This allows measurement of pressure distribution on inclined surfaces, expanding the measurement capability beyond flat surfaces and addressing the need for realistic ski route simulation.
2Adaptability or versatility
If the sensor surface is tilted relative to longitudinal axis by means of tilting device, then adaptability to different ski route inclinations is improved, but device complexity increases
Solution Approach 1:
The sensor surface is made tiltable relative to the longitudinal axis through a tilting device, transforming a static measurement surface into a dynamic one that can adapt to different inclination angles. This enables the system to simulate various ski route conditions and measure pressure distribution under different gravitational vector orientations, directly improving adaptability.
