Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Forming stable and exact bores in hard-to-reach locations of workpieces is challenging due to unsupported free lengths between the drive-side end and the drill bit, especially in difficult-to-access areas where traditional milling tools cannot reach.
Innovation Solution
A device comprising a drilling tool and a support device with a telescopic base body, allowing adjustable length support along the drilling tool's axis, ensuring stable positioning and exact bore formation even in deep or elongated workpieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a drilling tool is used to form bores in hard-to-reach locations, then the device can access difficult-to-access areas, but the unsupported free length between the drive-side end and the drill bit causes instability and positioning errors
Solution Approach 1:
A support device with support elements is introduced as an intermediary between the drilling tool and the workpiece. These support elements contact the workpiece at multiple points along the drilling path, providing mechanical support to the drilling tool and reducing the effective unsupported free length, thereby improving positioning accuracy while maintaining accessibility to hard-to-reach locations
Solution Approach 2:
The support device is segmented into multiple support elements distributed along the drilling path. Each support element provides localized support at specific positions, dividing the long unsupported free length into multiple shorter segments, which collectively stabilize the drilling tool without interfering with access to difficult-to-reach areas
2Length of moving object
If the drilling tool is extended to reach deep or elongated bores, then the device can form deep holes with large length dimensions, but the unsupported free length increases causing greater instability
Solution Approach 1:
The support elements act as intermediaries that provide distributed mechanical support along the extended drilling path. By contacting the workpiece at multiple intermediate positions, they prevent excessive deflection and vibration of the long drilling tool, maintaining stability even when forming deep or elongated bores
Solution Approach 2:
The support device is designed with adjustable support elements that can be positioned dynamically along the drilling path. This allows the support configuration to adapt to different drilling depths and tool geometries, optimizing stability for each specific deep-hole drilling operation
3Device complexity
If traditional milling tools are used, then the device structure is simple, but the device cannot reach difficult-to-access drilling positions
Solution Approach 1:
The support device is designed with universal support elements that can accommodate various drilling tool types and geometries. The support elements can be positioned and adjusted to work with different drill bit configurations, allowing a single support device structure to serve multiple drilling applications in hard-to-reach locations without requiring complex tool-specific adaptations
