Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction-extraction systems for handheld power tools are inefficient in ergonomics and suction performance due to rigid connections and lack of mobility, leading to suboptimal dust collection and user discomfort during drilling operations.
Innovation Solution
A suction-extraction aid with a joint unit that allows for movable connection to the handheld power tool and suction hose, providing rotational degrees of freedom and a spring element to prevent tilting, enhancing ergonomics and suction efficiency by ensuring direct dust collection at the drilling site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid connection is used to connect the suction-extraction aid to the handheld power tool, then the structural stability is improved, but the ergonomics and adaptability deteriorate
Solution Approach 1:
The patent applies the dynamics principle by replacing the rigid fixed connection with a movable joint unit that allows the suction-extraction aid to pivot and adjust its position dynamically. The joint unit enables rotational movement around a pivot axis, allowing the aid to adapt to different working positions while maintaining stable connection during operation.
Solution Approach 2:
The patent implements parameter changes by introducing a spring element that applies a predetermined force to maintain contact between the suction-extraction aid and the handheld power tool. The spring force can be adjusted to optimize the connection stability while allowing necessary movements for ergonomic operation.
2Reliability
If a fixed connection is used between the suction-extraction aid and suction hose, then the connection stability is improved, but the adaptability and ergonomics worsen
Solution Approach 1:
The joint unit provides dynamic adaptability by allowing the suction-extraction aid to rotate and pivot relative to the handheld power tool and suction hose assembly. This enables the system to adapt to various working angles and positions while the spring element maintains reliable connection through continuous contact force.
Solution Approach 2:
The connection system is segmented into multiple components: the suction-extraction aid, the joint unit with pivot axis, the handheld power tool interface, and the suction hose connection. This segmentation allows each component to perform its specific function independently while maintaining overall system stability and adaptability.
3Ease of operation
If the suction-extraction aid is made detachably connectable to the application tool, then the ease of operation and adaptability are improved, but the device complexity increases
Solution Approach 1:
The detachable connection feature divides the system into separable components: the suction-extraction aid that can be attached to or detached from the application tool held in the tool receptacle. This segmentation enables easy attachment and removal while the joint unit provides the necessary connection mechanisms without excessive complexity.
