Ergonomic gripping mechanisms of a handheld air movement apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld air movement apparatuses, such as leaf blowers and vacuums, often require users to maintain an unnatural, unbalanced, and uncomfortable grip position due to fixed handles, which limits ergonomic efficiency and weight distribution.
Innovation Solution
The implementation of ergonomic gripping mechanisms with directional height adjustment, allowing the nozzle to be positioned closer to the target, is achieved through a pivotable handle connection that enables the tool portion to pivot relative to the handle portion, providing a natural grip orientation and improved weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed handle is used in handheld air movement apparatuses, then the structure is simple and manufacturing is easier, but the user must maintain an unnatural, unbalanced, and uncomfortable grip position
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed handle into a pivotable handle connection that allows the tool portion to pivot relative to the handle portion. This dynamic adjustment enables users to achieve a natural grip orientation and improves weight distribution, directly resolving the contradiction between operational comfort and structural simplicity.
2Productivity
If the nozzle is positioned away from the target, then the apparatus structure is simpler, but the airflow or suction efficiency is reduced
Solution Approach 1:
The pivotable handle connection enables dynamic positioning of the nozzle closer to the target, improving airflow or suction efficiency. The mechanism allows the tool portion to be angled optimally while maintaining structural simplicity through a single pivot connection point.
3Ease of operation
If the handle is fixed in position, then the device structure is simpler, but weight distribution is unbalanced and causes user discomfort
Solution Approach 1:
The patent implements a pivotable handle connection that allows the tool portion to pivot relative to the handle portion, enabling dynamic adjustment of weight distribution. This creates a more balanced and comfortable user experience while maintaining relatively simple structural implementation.

AI summary
Ergonomic gripping mechanisms of handheld air movement apparatuses are provided. A handheld air movement apparatus may include a handle portion and a tool portion. The handle portion may include a grip, a trigger, and a handle pivot. The grip may have first and second ends. The trigger may be positioned toward the first end of the grip and the handle pivot may be positioned toward the second end of the grip. The tool portion may include a housing, a nozzle coupled to the housing, and a handle connection base. The tool portion may provide air movement into and/or out of the nozzle in response to a signal received from the trigger of the handle portion. The handle connection base of the tool portion may be pivotally coupled to the handle portion at the handle pivot to provide directional height adjustment of the tool portion with respect to the handle portion.
