Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool clamping devices for portable power tools lack a simple and efficient mechanism for securely clamping and releasing machining tools, particularly saw tools, which results in complex designs, increased assembly costs, and reduced operating convenience.
Innovation Solution
A tool clamping device with a movably mounted release element and a movement-arresting element fixedly connected to the clamping element, where the movement arresting element is integral with the clamping element and extends transversely, allowing for a stable and compact design that enables easy operation and rapid tool attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex release mechanism is used to secure the machining tool, then the clamping reliability is improved, but the device complexity increases and ease of operation deteriorates
Solution Approach 1:
The release element is merged with the clamping element to form an integrated unit. The release element includes a release arm that is directly connected to the clamping arm, allowing the release mechanism to be activated by a simple lever motion rather than requiring a complex separate release system. This integration maintains reliable tool securing while simplifying the overall mechanism structure.
Solution Approach 2:
The release element serves multiple functions: it acts as both a clamping component (through the clamping arm) and a release mechanism (through the release arm). The single lever operation can both secure and release the machining tool, eliminating the need for separate complex release mechanisms and reducing overall device complexity while maintaining operational reliability.
2Reliability
If multiple separate components are used for clamping and releasing, then the reliability is improved, but the assembly cost and device complexity increase
Solution Approach 1:
The release element is constructed as an integrated component where the release arm and clamping arm are directly connected. This merging of functions into a single component reduces the number of parts that need to be manufactured and assembled, lowering assembly costs while maintaining the reliable clamping and release functionality through the coordinated motion of the integrated arms.
3Volume of moving object
If a compact clamping mechanism is used, then the structural space is reduced, but the operating convenience may deteriorate
Solution Approach 1:
The release element is designed with dynamic movement capabilities, allowing the release arm to pivot through a sufficient angular range to provide easy lever operation. Despite the compact overall structure, the dynamic design ensures that the operator can apply force effectively through the lever arm, maintaining operating convenience within the constrained space of the portable power tool.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a high degree of operating convenience, allows for one-handed operation, and reduces assembly costs and structural space, while ensuring a secure and reliable clamping mechanism, enabling efficient use of portable power tools.
Implementation Method 1
The clamping element is preferably realized as an elastic clamping element. Particularly preferably, therefore, the clamping element generates the clamping-in force as a result of elastic deformation.

AI summary
A tool clamping device, in particular a saw-tool clamping device, for a portable power tool, includes at least one clamping unit configured to clamp-in a machining tool, which comprises at least one movably mounted release element configured to transfer the clamping unit into a releasing position, at least one clamping element configured to produce a clamping-in force acting on the machining tool, at least in a state of the machining tool in which the machining tool is connected to the clamping unit, and at least one movement-arresting element configured to arrest at least one possibility of movement of the release element in at least one state. The movement-arresting element is fixedly connected to the clamping element.
