Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool systems with axial screw connections require significant space, making them unwieldy and limiting their range of use, and often necessitate the use of special tools for output changes, which complicates quick adjustments and increases downtime in industrial applications.
Innovation Solution
A tool output changing system that allows for play-free, central attachment of outputs to motor-driven tools without the need for special tools, using a coupling module with Hirth gearing and clamping mechanisms for secure, tool-free quick changes, enabling a compact design and versatile operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If axial screw connections are used to secure outputs to the tool, then the connection is secure and reliable, but the tool requires a relatively large amount of space and becomes unwieldy
Solution Approach 1:
The patent replaces the traditional axial screw connection mechanism with a radial clamping mechanism. The coupling module uses radial clamping elements that engage with the output's clamping surfaces, eliminating the need for axial screw threads and union nuts. This substitution maintains secure connection while significantly reducing the space required along the tool's axial direction.
2Reliability
If union nuts are used to secure outputs, then the connection is firm, but the mounting area cannot be used for other purposes such as attaching additional components or routing cables
Solution Approach 1:
The patent transitions from axial mounting (union nuts on the end face) to radial mounting (clamping elements on the cylindrical surface). The coupling module engages with the output radially, freeing the axial end face for additional components and cable routing while maintaining secure connection through radial clamping forces.
3Reliability
If traditional axial screw connections are used, then the connection is secure, but tool-free output changes are not possible and special tools are required
Solution Approach 1:
The coupling module incorporates self-contained clamping and release mechanisms that can be actuated directly by the user without requiring external tools. The radial clamping elements can be engaged and disengaged through simple manual operation, enabling tool-free output changes while maintaining secure connection during operation.
4Manufacturing precision
If axial clamping is used to secure outputs, then the connection is play-free and central, but the tool design becomes more complex
Solution Approach 1:
The coupling module serves multiple functions: it provides radial clamping for secure connection, enables tool-free output changes, maintains play-free and central attachment, and frees the axial mounting area for additional components. This multi-functionality achieves high precision attachment without proportionally increasing overall system complexity.
