Power Tool Suction Extractor Fastening for Secure Tool Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held power tool suction extractor apparatuses lack a stable and easy-to-handle fastening mechanism that securely attaches to various power tools without requiring complete release for adjustment, and they often fail to accommodate different tool sizes and types effectively.
Innovation Solution
The proposed hand-held power tool suction extractor apparatus features a fastening unit with movably mounted position fixing elements, a variably adjustable fastening element, and exchangeable adapter elements, allowing for secure attachment and adjustable connection to different power tools and suction units, enabling single-handed operation and adaptation to various tool sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fastening mechanism is designed to be secure and stable, then the attachment reliability improves, but the ease of adjustment and operation deteriorates
Solution Approach 1:
The fastening element is designed with movable mounting that allows it to shift and adapt dynamically during attachment, enabling secure fastening while maintaining ease of adjustment through continuous position optimization rather than fixed rigid connections
Solution Approach 2:
The fastening mechanism allows changing of attachment parameters such as position, angle, and tension through the movable mounting system, enabling the same fastening element to achieve both secure attachment and easy adjustment by varying these parameters
2Adaptability or versatility
If a fastening unit is designed to accommodate different power tool sizes and types, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The fastening unit is designed as a universal attachment system that can secure various types of power tools through a single standardized interface, eliminating the need for multiple specialized fastening mechanisms and thereby reducing overall device complexity while maintaining high adaptability
Solution Approach 2:
The fastening unit is divided into modular components including the main body, movable fastening element, and position fixing element, allowing independent optimization of each segment and simplifying the overall structure while maintaining versatility across different tool types
3Ease of operation
If position fixing elements are made movable rather than fixed, then the ease of adjustment improves, but the stability during operation may deteriorate
Solution Approach 1:
The position fixing element transitions from a static fixed position to a movable adjustable position during operation, allowing easy adjustment followed by secure locking, thus achieving both ease of operation and operational stability through controlled dynamic behavior
Solution Approach 2:
The movable position fixing element allows preliminary adjustment to the optimal position before final securing, enabling the operator to first easily position the fastening element correctly and then lock it stable, separating the adjustment phase from the securing phase
