Blower Apparatus with Pivotable Handle for Suction and Blowing Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blower and vacuum apparatuses lack ergonomic design, making them uncomfortable to use in different operating modes and not adaptable to the specific forces required for suction and blowing operations.
Innovation Solution
A blower apparatus with a pivotable handle that adjusts its inclination relative to the discharge direction, allowing for two operating modes, and a vacuum apparatus with a supplemental handle that can be mounted on either side for ergonomic operation by both right- and left-handed users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the handle is fixed in a single position, then the structure is simple, but the apparatus cannot be ergonomically adapted to different operating modes (suction/blowing)
Solution Approach 1:
The handle is made pivotable rather than fixed, allowing it to dynamically adjust between at least two positions. The pivotable mounting enables the grip region to change its inclination relative to the discharge direction, adapting the force transmission characteristics to match different operating modes (suction or blowing) without requiring multiple separate handles or complex adjustment mechanisms.
2Ease of operation
If the grip region is inclined at one fixed angle, then the manufacturing is simple, but the force transmission cannot be optimized for different operating modes
Solution Approach 1:
The handle provides different local qualities (inclination angles) for different operating conditions. In the first position, the grip region has a first inclination optimized for suction mode force transmission. In the second position, the grip region has a second inclination optimized for blowing mode force transmission. This allows the same handle structure to provide mode-specific ergonomic optimization without requiring multiple specialized handles.
3Adaptability or versatility
If the handle is mounted rigidly, then the structure is stable, but the operator cannot adapt the grip orientation to reduce strain during different operations
Solution Approach 1:
The mounting mechanism transforms from a rigid fixed connection to a pivotable dynamic connection. This allows the handle to rotate between at least two positions, enabling the operator to adapt the grip orientation to reduce strain during different operations. The pivotable mounting provides the necessary degrees of freedom for ergonomic adaptation while maintaining structural stability in each positioned state.

AI summary
A blower apparatus is driven by a drive motor and has an intake opening and a discharge opening. The blower apparatus has a handle for guiding the blower apparatus with the handle being mounted on the blower apparatus such that it is pivotable from a first position into at least a second position. The blower apparatus is configured such that, during operation of the blower apparatus, an air flow passes through the discharge opening in a discharge direction. The handle has a grip region, which, in the first position, is inclined differently with respect to the discharge direction compared with the second position.
