Hand vacuum cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand vacuum cleaners often lack ergonomic design, leading to discomfort and reduced efficiency during use due to poorly distributed weight and placement of components.
Innovation Solution
A hand vacuum cleaner design featuring a pistol grip handle with a finger grip area between the handle and the air treatment member, where the suction motor and power supply are housed in a body portion overlying the finger grip and handle, and optional additional energy storage members positioned to enhance cleaning power and battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If heavier operating components (energy storage member, motor, power supply) are concentrated in one location, then cleaning power and battery life are enhanced, but weight distribution and user comfort deteriorate
Solution Approach 1:
The patent applies local quality by positioning heavier components (energy storage member, motor, power supply) specifically in the body portion that overlies the finger grip area and upper end of the pistol grip handle. This localized concentration of mass in a specific region optimizes weight distribution for handheld operation while maintaining enhanced cleaning power and extended battery life.
2Ease of operation
If components are distributed to improve ergonomics, then user comfort is enhanced, but cleaning power and battery life may be reduced
Solution Approach 1:
The patent achieves equipotentiality by positioning the body portion containing heavier components to overlie the finger grip area and upper end of the pistol grip handle, creating a balanced weight distribution that enhances ergonomics. This strategic placement ensures that the center of gravity aligns with the user's hand grip, reducing fatigue and improving control during extended cleaning sessions.
3Duration of action of moving object
If multiple energy storage members are added to extend battery life, then duration of action is enhanced, but device complexity and weight increase
Solution Approach 1:
The patent applies merging by integrating multiple energy storage members within the body portion of the handheld vacuum cleaner. This consolidation approach extends battery life and duration of action while maintaining a unified structural design, thereby managing device complexity through efficient spatial arrangement rather than adding separate systems.

AI summary
A hand vacuum cleaner has an air flow path extending from a dirty air inlet to a clean air outlet. An air treatment member and suction motor are positioned in the air flow path. The air treatment member is provided at the front end of the hand vacuum cleaner and has an air outlet provided at the rear end of the air treatment member. A pre-motor filter housing is provided rearward of the air treatment member. A pistol grip handle has an upper end that is mounted to the pre-motor filter housing.
