Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a thin window portion is used for measurement light transmission, then light transmission is improved, but moldability and structural strength deteriorate
Solution Approach 1:
The patent uses a copolymer comprising a cyclic olefin and a different monomer as the adapter forming material. This composite material structure provides both the thinness required for light transmission and the moldability needed for manufacturing. The specific copolymer composition enables the window portion to be formed thinly while maintaining structural integrity and ease of molding.
2Illumination intensity
If a thin window portion is used for measurement light transmission, then light transmission is improved, but structural strength deteriorates
Solution Approach 1:
The copolymer material combines cyclic olefin with another monomer to create a composite structure that maintains strength despite thinness. This material composition allows the window portion to achieve the required mechanical strength while remaining thin enough for effective light transmission.
Solution Approach 2:
The patent specifies particular parameters for the copolymer material, including the types of monomers used and their proportions. By controlling these material parameters, the window portion achieves optimal balance between thickness (for light transmission) and structural strength.
3Manufacturing precision
If the adapter is made thin and integrated, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent integrates the window portion and flow tube portion into a single molded structure. This merging of components into one integrated part improves manufacturing precision by eliminating assembly steps and potential misalignment, while the use of a single copolymer material simplifies the overall composition despite the integrated design.
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
The adapter provides enhanced moldability and strength, enabling easier and more precise integration of the window and flow tube portions, improving light transmission and reducing production costs.
Implementation Method 1
a window portion configured to allow measurement light for measuring a component of the gas passing through the flow tube portion to pass through the window portion
Implementation Method 2
The higher the concentration of carbon dioxide in the respiratory gas is, the stronger the measurement light (infrared light) is absorbed
