Drive Multiplying Device for Simultaneous Multi-Hole Drilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive multiplying devices are inadequate for simultaneous drilling of multiple holes efficiently, as they lack a mechanism to synchronize the rotation of multiple drill bits effectively.
Innovation Solution
A drive multiplying device comprising a housing with a drive shaft and multiple second shafts, each coupled to a drill bit, and a gear set that rotates the second shafts in unison with the drive shaft, allowing concurrent rotation of drill bits through a system of gears and sprockets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional single-shaft drive system is used, then the device complexity is low, but the productivity is reduced because multiple holes cannot be drilled simultaneously
Solution Approach 1:
The drive system is segmented into multiple independent shafts (drive shaft and multiple second shafts), each capable of rotating a drill bit. This segmentation allows simultaneous drilling operations while maintaining manageable complexity through modular architecture.
Solution Approach 2:
Multiple drive shafts are merged into a single integrated housing structure with a common gear set. This combining approach enables synchronized multi-hole drilling while consolidating control mechanisms, thereby increasing productivity without proportionally increasing device complexity.
2Manufacturing precision
If multiple drill bits are rotated independently, then the manufacturing precision is reduced, but the ease of operation is improved
Solution Approach 1:
A gear set acts as an intermediary mechanism between the drive shaft and second shafts. This intermediary ensures synchronized rotation of all drill bits through mechanical engagement, maintaining hole positioning precision while avoiding complex electronic control systems.
Solution Approach 2:
The patent uses a purely mechanical gear-based synchronization system instead of electronic controllers or sensors. This mechanical substitution achieves precise synchronization reliably while keeping the device structure simple and robust.
3Manufacturing precision
If a gear set is introduced to synchronize multiple shafts, then the manufacturing precision is improved, but the device complexity increases
Solution Approach 1:
The gear set serves multiple functions simultaneously: it transmits rotational motion from the drive shaft to multiple second shafts, synchronizes their rotation speeds, and maintains precise angular relationships. This multi-functionality achieves high drilling alignment precision without requiring separate mechanisms for each function.
Solution Approach 2:
The gear set is nested within the housing structure, with gears arranged in a compact configuration where components are integrated within each other. This nesting approach minimizes the space required for the synchronization mechanism and reduces overall device complexity while maintaining precision.

AI summary
A drive multiplying device for simultaneous drilling of multiple holes includes a housing. A drive shaft is rotationally coupled to and positioned through a first face of the housing. A first end of the drive shaft extends from the first face of the housing. A plurality of second shafts is rotationally coupled to and positioned through a second face of the housing. A first terminus of each second shaft extends from the second face of the housing. A gear set is positioned in the housing and is gearedly coupled to the drive shaft as well as each of the second shafts. The first end of the drive shaft is configured to couple to a rotary tool. The drive shaft is positioned to compel the gear set to rotate the second shafts. Drill bits coupled to the first termini of the second shafts are rotated concurrently with the drive shaft.
