Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual bone boring operation is performed by operator using surgical drill device, then operator can conduct the operation with flexibility, but the accuracy of boring operation degrades depending on operator skill level and substantial time is required
Solution Approach 1:
The patent introduces an assistant tool with supporting rods as an intermediary device between the operator and the bone boring operation. The supporting rods provide physical guidance and constraints that mediate the drilling process, ensuring consistent accuracy independent of operator skill while reducing the time needed for precise positioning and depth control
Solution Approach 2:
The supporting rods are pre-positioned and configured before the boring operation begins. The depth indicators and stoppers are set in advance to predetermined values, allowing the operator to perform the boring operation without needing to continuously measure or adjust parameters during the process, thereby improving accuracy and reducing time
2Manufacturing precision
If manual bone boring operation is performed by operator, then operator can adjust drilling parameters, but it is difficult to bore bone of exact diameter and depth intended
Solution Approach 1:
The assistant tool acts as a mediator that translates the operator's intent for exact diameter and depth into precise physical constraints. The supporting rods with their specific geometries and the depth indicators serve as intermediaries that ensure the drilling parameters match the intended values, removing the difficulty of achieving precision while maintaining operator control
Solution Approach 2:
The patent incorporates depth stoppers and limiting features that are prepared in advance to prevent over-drilling. These protective features are set before the operation to cushion against potential errors, ensuring that even if the operator makes a mistake, the exact depth intended will be achieved without exceeding it
3Reliability
If supporting rods are used to support boring drill to work area, then boring accuracy is improved and safety is ensured, but device structure becomes more complex
Solution Approach 1:
The assistant tool is segmented into multiple independent supporting rods rather than using a single complex support structure. Each rod can be independently positioned and adjusted, providing reliability through redundancy while keeping the overall device structure simpler and more modular. The supporting rods are distributed around the instrument body to provide stable support without requiring complex interconnections

AI summary
The present invention relates to a medical drill device. The medical drill device includes a boring drill including a motor and a drill part; an instrument body coupled to the boring drill; and a plurality of supporting rods coupled to the instrument body so as to support the boring drill to a work area. Each of the supporting rods includes: a straight portion inserted into the corresponding supporting rod insertable part in such a manner that the supporting rod is linearly moved with the instrument body; and a bent portion bent at a predetermined angle from the straight portion. As such, by using the supporting rods having a bent structure to support a boring drill to a work area and simultaneously limiting a boring depth of the boring drill, it is possible to shorten boring time and ensure safety of the boring operation.
