Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional cancer diagnosis methods are used, then general cancer detection is possible, but detection of Na/K-ATPase-mediated Src signaling specifically is not achieved
Solution Approach 1:
The patent employs specific antibodies as intermediaries that selectively bind to phosphorylated Y260 residue of Na/K-ATPase, enabling indirect detection of Src signaling activity. These antibodies serve as mediators between the phosphorylation event and the detection system, translating molecular modifications into measurable signals through immunodetection methods.
Solution Approach 2:
The patent replaces conventional mechanical or physical detection methods with biochemical detection systems. By using antibody-antigen recognition and subsequent signal amplification through enzymatic reactions or fluorescent labels, the system substitutes direct physical measurement with biochemical interaction-based detection, achieving higher sensitivity for phosphorylation detection.
2Reliability
If general cancer diagnosis methods are used, then broad cancer screening is possible, but accurate prognosis based on metabolic switches is not achieved
Solution Approach 1:
The patent focuses detection on a specific molecular feature - the phosphorylation state of the Y260 residue in Na/K-ATPase - rather than attempting to measure all possible cancer-related parameters. This localized approach to quality assessment provides reliable prognostic information about metabolic switches and Src signaling status without requiring comprehensive analysis of the entire cancer phenotype.
Solution Approach 2:
The patent develops a detection method that serves multiple functions: it detects Src kinase activity, indicates metabolic switch status, provides diagnostic information, and enables prognostic assessment. By creating a multi-functional assay that simultaneously provides several types of clinical information through a single measurement approach, the method achieves high reliability without proportionally increasing complexity.
