Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If real-time monitoring of operating parameters is implemented, then tissue sealing precision is improved, but device complexity increases
Solution Approach 1:
The system continuously monitors operating parameters (jaw angle, tip force, torsional force) and provides real-time feedback to the user through visual displays and audible alerts. This feedback mechanism enables precise control of tissue sealing parameters while managing device complexity through integrated sensor systems that automatically track multiple parameters simultaneously.
Solution Approach 2:
The patent replaces manual mechanical assessment with electronic sensing systems. Sensors electronically measure jaw angle, tip force, and torsional force, substituting complex mechanical measurement mechanisms with streamlined electronic detection systems that reduce overall device complexity while improving measurement precision.
2Measurement precision
If multiple sensors are integrated to monitor operating parameters, then measurement precision is improved, but device complexity increases
Solution Approach 1:
Multiple sensing functions (jaw angle detection, tip force measurement, torsional force sensing) are merged into a single integrated computing device that processes all parameters centrally. This consolidation reduces device complexity by eliminating redundant processing units while maintaining high measurement precision through coordinated sensor arrays.
Solution Approach 2:
The computing device serves multiple functions: it processes data from various sensors, displays operating parameters, generates audible alerts, and controls electrosurgical output. This multi-functional design reduces overall system complexity by consolidating control functions into a single universal processing unit rather than requiring separate dedicated systems for each function.
3Reliability
If visual and audible alerts are provided for parameter deviations, then reliability is improved, but device complexity increases
Solution Approach 1:
The system provides immediate feedback through visual displays showing actual versus ideal parameter ranges and audible alerts when parameters deviate from optimal values. This feedback loop enhances sealing reliability by enabling real-time correction while managing complexity through automated threshold monitoring that eliminates the need for continuous manual parameter assessment.
Solution Approach 2:
The computing device automatically monitors operating parameters, compares them against ideal ranges, and generates alerts without requiring external intervention. This self-service monitoring system improves reliability through continuous automated surveillance while reducing device complexity by eliminating the need for additional external monitoring equipment or manual checking procedures.
