Removable Tool Module Locking for Safe Quick Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool devices require time-consuming disassembly and can be accidentally triggered during repairs or cleaning due to the lack of a secure mechanism for removing modules.
Innovation Solution
A tool device design featuring a pressure locking element with a latching mechanism that allows for quick and safe removal of modules, where the pressure locking element is rotatable between normal and disassembly positions, and a latching mechanism engages to prevent accidental triggering when the second module is removed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If modules are connected with threads for removal, then modules can be disassembled, but the disassembly process becomes time-consuming
Solution Approach 1:
The locking mechanism is segmented into distinct functional elements: a locking element on one module, a corresponding locking receptacle on the other module, and a covering element that controls access. This segmentation allows the locking mechanism to be engaged or disengaged as a unit, enabling rapid module connection and disconnection without time-consuming threading operations.
Solution Approach 2:
The locking element is pre-positioned and spring-biased to automatically engage with the locking receptacle when modules are connected. Similarly, the covering element is pre-positioned to automatically cover the locking receptacle during operation, preventing accidental disengagement without requiring additional operational steps.
2Ease of repair
If modules can be easily removed, then maintenance and cleaning become simpler, but accidental triggering of the tool may occur
Solution Approach 1:
The covering element acts as an intermediary between the locking mechanism and the external environment. It physically covers the locking receptacle during operation, preventing unintended interaction with the locking mechanism while still allowing intentional module removal when the cover is deliberately moved. This intermediary protects against accidental triggering without compromising ease of repair.
Solution Approach 2:
The locking mechanism incorporates preliminary anti-action through the spring-biased locking element that automatically engages to secure modules during operation. This pre-engaged locking state prevents accidental disengagement or triggering, while the covering element provides an additional layer of protection by physically blocking access to the locking interface.
3Reliability
If a locking mechanism is added to prevent accidental triggering, then safety improves, but device complexity increases
Solution Approach 1:
The locking mechanism merges multiple functions into a compact structure: the locking element provides both the locking action and the interface for the covering element; the spring provides both biasing force and the release mechanism; the covering element simultaneously protects the locking interface and provides a user interface for intentional release. This merging minimizes the number of separate components while achieving reliable accidental activation prevention.
Solution Approach 2:
The locking element serves multiple functions: it engages with the locking receptacle to secure modules, provides a mechanical interface for the covering element, and works with the spring to enable both automatic locking and intentional release. The covering element similarly serves multiple functions: protecting the locking interface, providing a user interface for release, and preventing accidental triggering. This multi-functionality reduces overall device complexity.

AI summary
Power tool, comprising a first module and a second module which can be removed from the first module, wherein the first and the second module can be inserted into one another along an insertion axis defining an insertion direction, wherein the first module has a pressing inhibiting element, which is moved along with the second module, and a pressing blocking element, wherein the pressing inhibiting element can be rotated with respect to the pressing blocking element about the insertion axis between a normal position and a demounting position, wherein the second module is held against the first module in the normal position and can be removed from the first module in the demounting position, wherein the pressing blocking element allows the pressing inhibiting element to be transferred along the insertion axis towards the rest of the first module into a pressing position when the pressing inhibiting element is in the normal position, whereas the pressing blocking element blocks the insert fitting from being transferred into the pressing position when the pressing inhibiting element is in the demounting position, and wherein the first module has a latching mechanism which brings about latching engagement of the pressing inhibiting element in the demounting position when the second module is removed from the first module.
