Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate imaging and procedural equipment are used, then device versatility is maintained, but visualization precision and coordination deteriorate
Solution Approach 1:
The patent combines separate imaging devices and procedural instruments into a single integrated handle assembly. The imaging device (e.g., ultrasound transducer) and procedural instrument (e.g., catheter, needle, or ablation tool) are merged into one unified assembly that maintains both imaging capabilities and procedural functionality while improving coordination and visualization precision.
Solution Approach 2:
The handle assembly serves multiple functions simultaneously - it provides imaging capabilities, procedural instrumentation, and mechanical coordination all within a single device. This multi-functional design eliminates the need for separate equipment while maintaining versatility across different medical procedures.
2Productivity
If separate imaging and procedural equipment are used, then device versatility is maintained, but procedure time and efficiency worsen
Solution Approach 1:
By merging imaging and procedural equipment into a single handle assembly, the system eliminates the time required to coordinate between separate devices, switch between imaging modes, and realign equipment during procedures. The integrated design allows seamless transition between imaging and procedural actions without time loss.
Solution Approach 2:
The handle assembly enables continuous useful action by maintaining constant imaging guidance throughout the entire procedural sequence without interruption. The imaging device remains positioned and functional alongside the procedural instrument, allowing uninterrupted visualization and action coordination.
3Reliability
If separate imaging and procedural equipment are used, then device versatility is maintained, but safety and reliability worsen
Solution Approach 1:
The integration of imaging and procedural equipment into a single handle assembly reduces coordination complexity by eliminating interfaces between separate devices. This unified structure ensures consistent positioning, improves imaging guidance reliability, and enhances procedural safety through better coordination.
Solution Approach 2:
The handle assembly acts as an intermediary structure that mediates between the imaging device and procedural instrument, ensuring precise alignment and reliable coordination. This intermediary design simplifies the relationship between components while maintaining safety through controlled integration.
4Ease of manufacture
If separate imaging and procedural equipment are used, then device versatility is maintained, but cost worsens
Solution Approach 1:
The patent merges multiple separate equipment items into a single handle assembly, reducing the total quantity of equipment needed. This integration lowers costs by eliminating redundant components, reducing equipment maintenance requirements, and simplifying the overall system while maintaining manufacturing feasibility through modular design.
