Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cardiopulmonary exercise testing (CPET) with gas exchange measurement is used to assess cardiometabolic health, then measurement precision and reliability are improved, but device complexity and testing space requirements increase significantly
Solution Approach 1:
The patent uses blood lactate measurements as a simplified copy or proxy for the more complex CPET gas exchange measurements. By measuring lactate levels during exercise, the system captures similar physiological information about metabolic flexibility and cardiometabolic health without requiring expensive CPET equipment, thereby reducing device complexity while maintaining assessment precision
Solution Approach 2:
The patent replaces expensive, complex CPET equipment with inexpensive, portable lactate measurement devices. The lactate testing requires minimal infrastructure and can be performed in simple settings, making the assessment accessible to broader populations without the need for specialized laboratories
2Ease of operation
If generalized exercise recommendations are provided based on population averages, then ease of operation is improved, but adaptability to individual physiological attributes deteriorates
Solution Approach 1:
The patent implements feedback mechanisms that continuously monitor an individual's blood lactate responses during exercise and adjust exercise recommendations accordingly. This personalized feedback loop allows the system to adapt exercise intensity and duration based on the individual's actual physiological response, improving both accessibility through automated guidance and individualization through data-driven customization
Solution Approach 2:
The patent transitions from static, population-based exercise recommendations to dynamic, individualized programs that adjust in real-time based on measured lactate levels. The system adapts exercise parameters such as intensity, duration, and frequency based on the individual's metabolic response, making the recommendations both easy to follow through automation and highly adaptable to unique physiological characteristics
3Reliability
If sub-maximal effort testing protocols are used to ensure safety, then reliability and safety are improved, but measurement precision of maximal physiological capacity deteriorates
Solution Approach 1:
The patent changes the measurement parameter from direct maximal oxygen consumption (VO2 max) to blood lactate threshold and clearance rate. By measuring lactate dynamics during sub-maximal exercise, the system can safely assess metabolic flexibility and cardiometabolic health without requiring maximal effort, while still obtaining precise physiological data through the lens of lactate metabolism rather than direct respiratory gas exchange
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables personalized exercise protocols that effectively improve cardiometabolic health and fitness by observing blood lactate behavior at various intensity levels, providing safe and dynamic exercise programs tailored to individual physiological capabilities.
Implementation Method 1
Metabolism is the systemic integration of anabolic and catabolic physiology accounting for growth, maintenance, repair, and death. One of the main functions of metabolism is processing the macronutrients that we consume and transforming them into energy sources that the body can utilize at a cellular level to maintain the body structure and function.
Implementation Method 2
Mitochondria within muscle cells (Type I>Type 2) determine fat oxidative capacity, carbohydrate oxidative capacity, and more specifically, lactate oxidative capacity.
Implementation Method 3
Metabolic flexibility is known as the capacity of the body to switch fuels sources, such as switching between using fats and carbohydrates, to meet body's supply/demand needs (e.g., between fasting and feeding and between rest and exercise).
Implementation Method 4
Lactate (e.g., L-Lactate) is well-known as the endpoint of glycolysis. The first lactate threshold is the level at which the intensity of the exercise or stress on the body causes the lactate to accumulate in the blood at a faster rate than it is being removed by the body.
Implementation Method 5
Lactate can also be recycled back to glucose via the Cori Cycle in the liver.
