Solution Overview
Problem
Existing suction connection systems for portable machine tools lack a secure and easy-to-use mechanism for connecting to dust extraction devices, leading to inefficient dust removal during machining processes, which can result in health hazards and operational discomfort.
Innovation Solution
A suction connection system featuring a movably mounted fixing unit with a ring-shaped, spring-loaded fixing element that provides a secure and easy-to-operate connection between the machine connection element and the suction connection element, allowing for a plug-in connection and automatic positioning, ensuring compatibility with existing dust extraction devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a suction connection system without a fixing unit is used, then the device complexity is reduced, but the reliability of the connection deteriorates
Solution Approach 1:
The fixing element is designed to be movably mounted on the suction connection element, allowing it to transition between a retracted position (during connection) and a protruding position (during operation). This dynamic mechanism provides reliable fixation while maintaining ease of connection, resolving the contradiction between connection reliability and device complexity.
2Reliability
If a secure connection mechanism is implemented, then the connection reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The fixing element is pre-configured in a retracted position that allows the machine connection element to be easily inserted into the suction connection element. Once connected, the fixing element automatically moves to its fixing position, providing secure connection without requiring additional manual operations. This preliminary positioning resolves the contradiction between connection security and ease of operation.
3Ease of operation
If a movably mounted fixing element is added, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The fixing element is integrated directly onto the suction connection element, merging the fixation function with the existing connection structure. This integration approach provides easy operation through automatic fixing while minimizing the increase in device complexity by avoiding separate fixation components.
4Adaptability or versatility
If existing dust extraction devices are made compatible, then the adaptability is improved, but the manufacturing precision requirements worsen
Solution Approach 1:
The movably mounted fixing element allows for dynamic adjustment during the connection process, accommodating variations in dimensional tolerances of existing dust extraction devices. This dynamic adaptation mechanism enables compatibility with various devices without requiring extremely tight manufacturing precision.
