Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sensor unit is integrated into the work shoe to detect person-related and environmental characteristics, then wearer safety and comfort are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple sensor elements (acceleration, temperature, pressure, location) into a single integrated sensor unit within the work shoe. This merging approach improves wearer safety through comprehensive monitoring while managing device complexity by consolidating functions into one modular unit rather than分散 multiple separate systems.
Solution Approach 2:
The sensor unit is designed to perform multiple functions: detecting acceleration for fall detection, monitoring temperature for thermal comfort, measuring pressure for gait analysis, and tracking location for geofencing. This multi-functionality improves reliability through comprehensive monitoring while avoiding the complexity of separate specialized devices for each function.
2Measurement precision
If multiple sensor elements are integrated into the work shoe, then measurement precision of characteristic variables is improved, but device complexity increases
Solution Approach 1:
The patent divides the sensing function into distinct sensor elements (acceleration sensor, temperature sensor, pressure sensor, location sensor), each optimized for specific measurements. This segmentation improves measurement precision for each characteristic variable while managing complexity through modular design where each sensor element can be independently selected and positioned.
Solution Approach 2:
Different sensor elements are positioned at specific locations within the work shoe structure to optimize detection accuracy for their respective functions. For example, pressure sensors are placed in the sole to detect gait characteristics, while temperature sensors are positioned near the insole to monitor foot temperature, ensuring local optimization of measurement precision.
3Adaptability or versatility
If communication units are added for data exchange with external units, then adaptability and response capability are improved, but device complexity and energy consumption increase
Solution Approach 1:
The communication unit enables bidirectional data exchange between the work shoe and external units (mobile devices, servers). Sensor data is transmitted externally for analysis, and feedback is received to trigger responses such as alerts, notifications, or parameter adjustments. This feedback loop improves adaptability and response capability while managing complexity through standardized communication protocols.
4Ease of operation
If control units are integrated to adapt work shoe parameters based on detected variables, then comfort and safety are improved, but device complexity and energy consumption increase
Solution Approach 1:
The control unit dynamically adjusts work shoe parameters (such as stiffness, support, or ventilation) based on real-time sensor data detecting wearer characteristics and environmental conditions. This dynamic adaptation improves comfort and safety by automatically optimizing shoe performance for current conditions while managing complexity through algorithmic control rather than mechanical adjustments.
