Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If motion and force sensors are embedded in ski boots to collect real-time data, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent embeds multiple sensors (accelerometer, gyroscope, magnetometer, force sensors) within the ski boot structure, nesting the measurement system inside the existing footwear. This allows precise motion and force data collection without adding external complexity, as the sensors are integrated into the boot's insole and shell.
Solution Approach 2:
The ski boot system performs multiple functions: it serves as protective footwear while simultaneously acting as a motion capture platform, force measurement device, and communication system. The boot integrates GPS reception, wireless data transmission, and haptic feedback capabilities, eliminating the need for separate equipment and reducing overall system complexity.
2Loss of information
If multiple sensors are integrated into ski boots for comprehensive data collection, then information completeness is improved, but ease of operation deteriorates
Solution Approach 1:
The system automatically collects data from all embedded sensors, processes the information through the microcontroller, and transmits it wirelessly without requiring user intervention. The ski boot itself serves as the data collection and processing platform, eliminating the need for users to manually operate complex equipment or coordinate multiple devices.
Solution Approach 2:
The patent combines multiple data collection functions (motion sensing, force measurement, GPS tracking) into a single integrated system within the ski boot. This consolidation allows comprehensive data collection while simplifying operation, as the user simply wears the boot and the system handles all measurements and communications automatically.
3Productivity
If real-time data transmission is implemented during sporting events, then productivity is improved, but use of energy increases
Solution Approach 1:
The system transmits data in periodic bursts or at key event moments rather than continuously, reducing overall energy consumption while maintaining real-time functionality. The microcontroller can be configured to transmit data at specific intervals or when threshold events occur, balancing the need for timely information with power conservation during athletic activity.

AI summary
A method allowing the synchronizing collection of motion and ground reaction forces data at the start of a sporting event which are received from motion and force sensors embedded in insoles worn in the user's footwear. Furthermore, this method allows synchronization of said data with video or television transmission, and if used during, for example, during ski racing, provides information of skis' pitch, roll and heading in a 3-D space, as well as linear and angular velocity, g-forces, and the location and distribution of pressure points and ground reaction forces transferred to the user's feet in a numerical or a graphical form.
