Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If satellite positioning is used to acquire speed, then positioning and navigation functions are achieved, but measurement precision deteriorates under harsh environmental conditions
Solution Approach 1:
The patent introduces heart rate as an intermediary parameter to bridge the relationship between exercise intensity and speed. Instead of directly relying on satellite positioning which fails in harsh environments, the system uses heart rate monitoring as a mediator to infer equivalent speed, thereby maintaining measurement precision when direct measurement becomes unreliable.
Solution Approach 2:
The patent transforms the speed measurement problem by changing from direct physical speed measurement (prone to environmental interference) to physiological parameter-based equivalent speed calculation. By monitoring heart rate and converting it to equivalent speed through established relationships, the system maintains accuracy across varying environmental conditions.
2Adaptability or versatility
If conventional speed measurement is used, then simple speed data is obtained, but adaptability to complex environmental factors deteriorates
Solution Approach 1:
The patent makes the speed monitoring system universal by enabling it to function accurately across diverse environmental conditions (high altitude, extreme temperatures, slope variations). The heart rate-based equivalent speed calculation provides a unified approach that works universally regardless of specific environmental challenges, unlike satellite positioning which fails in certain conditions.
3Measurement precision
If heart rate monitoring is implemented, then physiological intensity accuracy is improved, but device complexity increases
Solution Approach 1:
The patent leverages the body's own physiological responses (heart rate) as the monitoring mechanism. Instead of requiring complex external sensing systems, the device utilizes the runner's inherent physiological data, which is easily obtainable through standard wearable sensors. This self-service approach achieves high precision without proportionally increasing system complexity.
