Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extraction connection systems for portable machine tools lack a secure and convenient method to connect tool and suction apparatus elements, leading to inefficient dust extraction during machining processes.
Innovation Solution
A modular extraction connection system featuring a movably mounted fixing element that interlocks between a tool connection element and a suction apparatus connection element, ensuring secure alignment and easy operation, compatible with existing dust extraction devices through adaptable connecting regions and spring-actuated mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a plug-in connection is used between tool connection element and suction apparatus connection element, then the connection can be quickly established and disconnected, but the connection lacks security and stability during operation
Solution Approach 1:
The fixing element is designed to be movable during connection establishment, allowing it to automatically engage with the counter element. Once connected, the fixing element becomes stationary to maintain stable connection. This dynamic transition resolves the contradiction between quick connection (ease of operation) and stable connection (reliability).
Solution Approach 2:
The fixing element automatically engages with the counter element through its own movement when the connection elements are plugged together. The system self-secures without requiring additional manual fastening actions, maintaining both ease of operation and connection stability.
2Reliability
If a secure fixing mechanism is added to the connection system, then connection stability is improved, but the device complexity increases
Solution Approach 1:
The fixing element is integrated as part of the connection system between the tool connection element and suction apparatus connection element. By merging the fixing function into the existing connection structure rather than adding separate complex fastening mechanisms, the solution achieves connection stability without significantly increasing device complexity.
Solution Approach 2:
The fixing element automatically secures the connection through its own movement and engagement with the counter element, eliminating the need for additional manual fastening operations or complex control systems. This self-securing mechanism maintains simplicity while ensuring reliable connection.
3Adaptability or versatility
If the fixing element is mounted movably on one connection element, then the connection system becomes more adaptable to alignment variations, but the manufacturing precision requirements increase
Solution Approach 1:
The fixing element is designed with movability that allows it to automatically adjust its position during the connection process. This dynamic adjustment capability provides adaptability to alignment variations while the manufacturing precision requirements are maintained within feasible ranges for the movable mounting structure.
