Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the sizer method is used to estimate breast implant volume, then the doctor can physically measure the breast size during surgery, but the surgery time is significantly increased and there is risk of patient damage or infection
Solution Approach 1:
The patent applies preliminary action by pre-establishing a linear model with determined coefficients and constants before surgery. The model parameters (coefficient and constant) are calculated in advance based on statistical data, allowing the doctor to quickly estimate implant volume during surgery using simple measurements rather than physical sizers, thus reducing surgery time while maintaining accuracy
2Measurement precision
If the sizer method is used to estimate breast implant volume, then the doctor can physically measure the breast size during surgery, but there is risk of patient damage or infection
Solution Approach 1:
The patent replaces the mechanical sizer system with a mathematical calculation system. Instead of inserting physical sizers into the patient's body, the system uses a linear model with pre-determined coefficients and constants that processes simple breast measurements to calculate implant volume, thereby eliminating the risk of patient damage or infection while maintaining estimation accuracy
3Ease of operation
If the breast tissue weight method is used to estimate implant volume, then the estimation can be obtained after mastectomy, but there is no absolute correlation and accuracy varies due to different conditions
Solution Approach 1:
The patent changes the parameter relationship by establishing a linear model with specific coefficients and constants that transform breast measurements into implant volume estimates. The model uses the relationship: implant volume = coefficient × breast measurement + constant, where the coefficients and constants are optimized through statistical analysis, providing accurate predictions without relying on post-mastectomy weight measurements
