Handheld Vacuum Handle Layout for Better Weight Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand-held vacuum cleaners are tiring and uncomfortable to use due to the center of mass being forward of the handgrip, requiring excessive effort to maintain orientation.
Innovation Solution
A hand-held vacuum cleaner design with a transverse elongate handle positioned at an angle close to 90° relative to the suction conduit's longitudinal axis, placing the handgrip between the airflow generator and power source for improved weight balance and ergonomic comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the motor and fan assembly and power source are arranged forwardly of the handgrip, then the components are easily accessible and installed, but the centre of mass is located forwardly of the handgrip resulting in the vacuum cleaner being tiring and uncomfortable to use
Solution Approach 1:
The patent repositions the handgrip from a longitudinal arrangement to a transverse arrangement perpendicular to the suction conduit axis. This dimensional change allows the handgrip to be positioned between the motor assembly and power source, achieving both easy component access and optimal weight distribution for user comfort.
2Device complexity
If the handgrip extends parallel to the elongate main body at a shallow angle to the suction conduit, then the structure is compact and simple, but the user experiences a weaker wrist position and reduced comfort
Solution Approach 1:
The patent employs asymmetric positioning of the handgrip at approximately 90 degrees to the suction conduit axis, creating an optimized ergonomic configuration that improves wrist position and user comfort while maintaining structural efficiency.
3Ease of operation
If the elongate handle is positioned transverse to the suction conduit at an angle close to 90 degrees, then the wrist position is comfortable and manipulation is easy, but the structural arrangement becomes more complex
Solution Approach 1:
The patent merges the handgrip position with the optimal weight balance point, positioning it between the motor assembly and power source. This combination achieves both ergonomic comfort and simplified structural integration, as the transverse handle naturally positions the user's hand at the balance point.

AI summary
A hand-held cleaning appliance includes a suction conduit having a longitudinal axis, an airflow generator generating an airflow along the suction conduit, a separating apparatus arranged in communication with the suction conduit for separating dirt and dust from the airflow, a power source supplying power to the airflow generator and an elongate handle disposed between the airflow generator and the power source. The elongate handle is dimensioned and arranged to be gripped by a user's hand and the elongate handle lies transverse to the longitudinal axis of the suction conduit. By providing a hand-held vacuum cleaner with such an arrangement, the hand-held vacuum cleaner is easier and more comfortable to manipulate in use.
