Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional monitoring solutions are used, then monitoring capability is provided, but cost is high and precision is insufficient
Solution Approach 1:
The system segments the monitoring function into multiple specialized sensors (force sensors, position sensors, motion sensors) distributed within the shoe insert, each measuring specific parameters independently to achieve high precision without requiring a single complex device
Solution Approach 2:
The shoe insert serves multiple functions simultaneously: it acts as a structural component of footwear while integrating force sensing, position tracking, and motion detection capabilities, eliminating the need for separate monitoring equipment
2Ease of operation
If traditional monitoring solutions are used, then monitoring capability is provided, but the solution is obtrusive
Solution Approach 1:
The monitoring system is merged with the shoe insert structure itself, combining the functional requirements of footwear with sensing capabilities into a single integrated component that users wear naturally without noticing
Solution Approach 2:
The system automatically collects and transmits data without requiring user intervention for operation, calibration, or maintenance, simply functioning as part of the shoe while the user wears it
3Measurement precision
If comprehensive sensor integration is implemented, then measurement precision is improved, but device complexity increases
Solution Approach 1:
A microcontroller serves as an intermediary that consolidates data from multiple sensors, processes the information centrally, and manages wireless transmission, simplifying the system architecture despite having multiple sensing elements
