Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple separate controls are used for axial and rotational movements of elongated medical devices, then control precision is improved, but device complexity and operator interaction complexity increase
Solution Approach 1:
The patent combines axial and rotational controls into a single integrated control element. The control member includes both axial movement capability and rotational movement capability, allowing simultaneous control of both degrees of freedom through one unified interface rather than separate controls, thereby reducing control interface complexity while maintaining precision
Solution Approach 2:
The control member is designed to perform multiple functions: it can control axial movement, rotational movement, and the combination of both movements of the elongated medical device. This multi-functional control element eliminates the need for multiple separate controls, simplifying the operator interface while preserving comprehensive control capability
2Reliability
If multiple operators are required for complex procedures like guidewire exchange, then operational reliability is improved, but productivity and efficiency decrease
Solution Approach 1:
The system enables a single operator to independently perform complex procedures that previously required multiple operators. The integrated control member allows one operator to simultaneously manage axial and rotational movements, making the system self-sufficient for complex tasks like guidewire exchange without requiring additional operator assistance
Solution Approach 2:
The patent accelerates procedural efficiency by enabling single-operator execution of complex procedures. The unified control interface allows rapid, coordinated manipulation of the elongated medical device, reducing procedure time and increasing throughput while maintaining the reliability previously achieved through multi-operator collaboration
3Measurement precision
If multiple controls are used for manipulating elongated medical devices, then control accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The control member merges axial and rotational control functions into a single ergonomic element. This unified design allows the operator to manipulate both degrees of freedom with one hand, improving ease of operation while maintaining the control accuracy that would otherwise require multiple separate controls
Solution Approach 2:
The control member is designed to operate in multiple dimensional spaces simultaneously - it can move axially along the longitudinal axis and rotate around the longitudinal axis. This multi-dimensional control capability is integrated into a single element, providing accurate control in multiple degrees of freedom while simplifying the operator interface
