Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ultracentrifugation is used to measure HDL3, then measurement precision is improved, but device complexity and operation difficulty increase
Solution Approach 1:
The patent introduces a specific surfactant (polyoxyethylene polycyclic phenyl ether or polyoxyethylene styrenated phenyl ether) as an intermediary substance that selectively interacts with HDL3. This surfactant acts as a mediator to enable specific binding and detection of HDL3 without requiring complex ultracentrifugation equipment, thus resolving the contradiction between measurement precision and device complexity
Solution Approach 2:
The patent replaces the mechanical ultracentrifugation system with a chemical interaction system based on surfactant-HDL3 binding. Instead of using mechanical force and complex separation mechanisms, the invention uses specific chemical affinity between the surfactant and HDL3 to achieve separation and measurement, thereby eliminating the need for expensive ultracentrifugation equipment
2Measurement precision
If HPLC is used to separate HDL2 and HDL3, then measurement precision is improved, but operation time and equipment requirements increase
Solution Approach 1:
The patent uses a specific surfactant as an intermediary that selectively binds to HDL3, enabling rapid separation and measurement without requiring time-consuming HPLC procedures. The surfactant-HDL3 complex can be detected directly, significantly reducing operation time while maintaining measurement precision
Solution Approach 2:
The patent changes the measurement approach from physical separation parameters (used in HPLC) to chemical interaction parameters (surfactant binding). By measuring the binding affinity and concentration of the surfactant-HDL3 complex, the method achieves rapid quantification without the lengthy separation processes required by HPLC
3Ease of operation
If HDL3 precipitation method is used, then ease of operation is improved, but measurement precision and reliability decrease due to interference from other lipoproteins
Solution Approach 1:
The patent applies local quality by using a surfactant with specific chemical properties that are selectively attracted to HDL3 while remaining indifferent to other lipoproteins. The surfactant's molecular structure provides specific binding affinity for HDL3, creating a localized interaction that does not interfere with other lipoprotein measurements, thus achieving both ease of operation and high precision
Solution Approach 2:
The surfactant serves as a specific intermediary that mediates the interaction between the measurement system and HDL3. This intermediary provides selective binding to HDL3, allowing the measurement system to distinguish HDL3 from other lipoproteins without requiring complex separation procedures, thereby maintaining both operational simplicity and measurement precision
