Engineering Contradiction Analysis
1Loss of information
If sensor systems are incorporated into footwear to collect performance data, then data collection capability is improved, but data accessibility and usability are worsened due to complexity and operating system compatibility issues
Solution Approach 1:
The sensor system is divided into separate functional modules: force sensors embedded in the sole structure, signal processing circuitry, and communication interfaces. This segmentation allows each component to be optimized independently and simplifies the overall system architecture, making data more accessible while reducing complexity.
Solution Approach 2:
The footwear sensor system is designed with universal communication capabilities that can interface with multiple operating systems and external devices. The system uses standardized data formats and protocols, enabling broad compatibility across different platforms (computers, mobile devices, analysis software) without requiring system-specific implementations, thus improving data accessibility while maintaining manageable complexity.

If sensor systems are incorporated into footwear to collect performance data, then data collection capability is improved, but data usability is worsened due to operating system compatibility restrictions
Solution Approach 1:
The communication port and interface circuitry are designed to support multiple communication protocols and operating systems simultaneously. The system can output data in universally readable formats that are compatible with various external devices including computers, mobile phones, and specialized analysis equipment, regardless of the operating system being used.
Solution Approach 2:
The patent introduces an intermediary communication layer between the sensor system and external devices. This intermediary uses standardized data formats and universal communication protocols that act as a bridge, allowing data to be transmitted and used across different operating systems without direct integration requirements, thereby improving data usability while expanding adaptability.
