Handheld Power Tool Adapter With Self-Locking Detent Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adapters for hand-held power tools require additional tools for installation and release, complicating handling and increasing the risk of accidental detachment.
Innovation Solution
A detachable adapter with a rotatably supported shaft and a locking unit featuring an elastic detent connection that automatically engages without manual intervention, providing a secure and user-friendly attachment mechanism using a detent connection that can be easily released manually.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional clamping fastenings are used to attach the adapter to the housing, then the adapter can be securely attached, but additional tools are required for installation and release, complicating handling
Solution Approach 1:
The adapter is designed with a self-locking mechanism that automatically engages when the adapter is attached to the housing. The locking element with its locking projection automatically engages with the corresponding recess in the housing, eliminating the need for additional tools during installation and release operations
2Reliability
If conventional clamping fastenings are used to attach the adapter to the housing, then the adapter can be securely attached, but the risk of accidental detachment increases due to complex operation
Solution Approach 1:
The locking mechanism automatically engages and locks the adapter to the housing without requiring complex manual operations. The self-locking feature prevents accidental detachment while maintaining simplicity in the fastening mechanism
Solution Approach 2:
The locking element is designed with elastic properties, allowing it to dynamically engage with the housing recess and maintain a secure connection. The elastic deformation enables automatic locking while preventing accidental release
3Ease of operation
If a bayonet connection device is used to clamp the adapter to the housing, then the adapter can be attached in the axial direction, but manual actuation is still required, reducing automation
Solution Approach 1:
The adapter incorporates an automatic locking mechanism where the locking element with its projection automatically engages with the recess in the housing during axial attachment. This eliminates the need for manual actuation steps required by traditional bayonet connections, achieving full automation of the locking process
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
Enables easy and secure attachment of the adapter to the hand-held power tool without additional tools, ensuring a stable connection and preventing accidental detachment, while allowing for simple manual release.
Implementation Method 1
an elastic detent means is forcibly guided against the force of the elastic detent means and engages with a corresponding means on the housing
