Universal Drill Connection Device for Cutting Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oscillation driven cutting tools require multiple drill units for different functions, such as cutting shears and metal shears, leading to inefficiencies and the need for multiple single-purpose drills.
Innovation Solution
A connection device comprising securable and movable shell members that clamp onto both the drill and the cutting tool, preventing rotation and axial separation, allowing for a single device to connect various tools to a drill or driver, thereby enabling multiple functions with a single unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple single-purpose drill units are used for different cutting functions, then each drill can be optimized for its specific function, but the quantity of tools required increases and operational efficiency decreases
Solution Approach 1:
The patent implements a universal drill unit with a standardized connection device that can attach various cutting tools (cutting shears, metal shears, board cutters, etc.) to a single drill body. The connection device features a standardized interface with clamping mechanisms that can securely hold different tool types, allowing one drill unit to perform multiple cutting functions that previously required separate specialized drills.
2Adaptability or versatility
If a standardized connection device is used to attach various cutting tools to a single drill, then the number of drill units is reduced, but the reliability of the connection between drill and tool may be compromised
Solution Approach 1:
The connection device is divided into distinct functional segments: a clamping mechanism with movable and fixed jaws, a securing system with screws or quick-release latches, and a standardized interface. This segmentation allows each component to be optimized for its specific function while maintaining overall connection reliability. The clamping jaws provide secure gripping, the securing system ensures firm attachment, and the standardized interface enables consistent connection across different tool types.
3Ease of operation
If the connection device uses movable shell members for clamping, then ease of tool attachment is improved, but the structural complexity of the connection device increases
Solution Approach 1:
The connection device incorporates dynamic elements including movable clamping jaws that can open and close to receive and secure tools, adjustable clamping force mechanisms, and quick-release features. These dynamic components enable operators to quickly attach and detach different cutting tools without complex assembly procedures. The movable shell members can be displaced to accommodate tool insertion and then secured in position, providing both ease of operation and reliable connection.

AI summary
The present invention provides a connection device or tool (10, 110, 210, 310, 410, 510, 610, 1110, 2110, 3110, 4110) to connect a first tool (80, 90) to a second tool (90,80), the connection device or tool (10, 110, 210, 310, 410, 510, 610, 1110, 2110, 3110, 4110) comprising at least one shell member 30 which clamps a first end to said first tool (80, 90) and a second end of said at least one shell member 30 to engage with said second tool (90,80), whereby relative rotation between said first tool and second tool is prevented, and axial separation of said first tool (80, 90) and second tool (90,80) is prevented or is assisted in being prevented. This results in a safer combination of the first tool (80, 90) and second tool (90,80), and allows for a one handed operation of the combination.
