Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single optical path length is used, then the device structure is simple, but the measurement range is limited and cannot effectively measure both low and high concentrations
Solution Approach 1:
The optical path length adjustment mechanism is segmented into multiple discrete positions (first position for long optical path, second position for short optical path). This allows the device to switch between different measurement ranges based on sample concentration, effectively resolving the contradiction between measurement range and structural simplicity.
Solution Approach 2:
The optical path length is made dynamically adjustable through a movable component that can switch between fixed positions. This dynamic adjustment capability enables the device to adapt to different measurement requirements without increasing overall structural complexity, as the adjustment mechanism shares common components with the existing optical system.
2Measurement precision
If optical path length is increased to measure small amounts of sample, then measurement resolution is improved, but reaction light reaches saturation state when sample amount is increased
Solution Approach 1:
The optical path length is made dynamically adjustable between long and short positions. When measuring small sample amounts, the long optical path enhances measurement resolution. When measuring high concentrations, the system switches to short optical path to prevent saturation, thus resolving the contradiction between precision and adaptability.
Solution Approach 2:
The optical path length parameter is changed based on sample concentration. By adjusting this physical parameter, the system optimizes measurement conditions for different concentration ranges, achieving both high resolution for dilute samples and avoiding saturation for concentrated samples.
3Adaptability or versatility
If additional optical parts or electric parts are added to adjust sensor sensitivity, then measurement range is extended, but device complexity increases
Solution Approach 1:
Instead of adding additional sensors or amplifiers, the system changes the optical path length parameter to adjust the effective measurement range. This approach extends adaptability without increasing device complexity, as it utilizes the existing optical components in different configurations.
Solution Approach 2:
The system uses its own optical path length adjustment capability to achieve sensitivity adjustment, eliminating the need for separate sensor sensitivity adjustment mechanisms. The optical system serves itself by providing multiple measurement ranges through geometric configuration changes rather than additional components.
4Adaptability or versatility
If light source intensity is increased to expand measurement range, then measurement capability for low concentrations is improved, but measurement accuracy for high concentrations deteriorates
Solution Approach 1:
The system dynamically adjusts the optical path length based on sample concentration rather than changing light source intensity. This dynamic geometric adjustment maintains measurement accuracy across different concentrations by optimizing the interaction path between light and sample, avoiding the saturation problems associated with intensity increases.
Solution Approach 2:
The optical path length parameter is changed to achieve measurement range expansion without altering light source intensity. This parameter change allows the system to maintain optimal signal-to-noise ratio and measurement accuracy across both low and high concentration ranges.
