Conversion Member for Adjustable Center-of-Gravity Vacuum Cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners lack a method to easily change the center of mass to a lower or higher position, limiting their versatility and convenience, as they often require additional devices for different cleaning purposes and restrict the size and functionality based on the center of gravity.
Innovation Solution
A conversion member that can be coupled to an existing electric cleaner, allowing the main body to be positioned at either a lower or higher position, with a secure and easy-to-use design that includes a coupling unit with rotatable coupling portions and a slip prevention mechanism, enabling self-standing and easy grip, even when the main body is at a lower position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the main body is located at the lower side of the vacuum cleaner, then the load on the handle is reduced and the size of the main body can be increased, but it becomes difficult to change direction while moving and difficult to secure sufficient distance between the main body and the intake port
Solution Approach 1:
The patent applies the dynamics principle by making the main body position adjustable rather than fixed. The conversion member allows the main body to be dynamically repositioned between lower and upper locations, enabling the system to adapt its center of gravity based on operational requirements. This resolves the contradiction by allowing the main body to be at the lower side for reduced handle load during normal operation, yet movable to other positions when direction changing or intake port spacing is needed.
2Ease of operation
If the main body is located at the upper side of the vacuum cleaner, then the user can easily lift the vacuum cleaner and achieve a lightweight design, but the load on the user's wrist is increased and the size of the main body is restricted
Solution Approach 1:
The conversion member enables dynamic repositioning of the main body between upper and lower positions. When lifting or maneuvering is required, the main body can be positioned upper to reduce overall weight and improve maneuverability. During stable cleaning operations, it can be positioned lower to transfer weight to the base, reducing wrist load. This dynamic adjustment resolves the contradiction between lifting ease and wrist load.
3Ease of operation
If a cordless vacuum cleaner is used to enable easy detachment and mobility, then convenience is improved, but the center of gravity becomes higher and a stand holder is required to maintain upright state
Solution Approach 1:
The conversion member provides dynamic adjustment of the main body position, allowing the center of gravity to be lowered when the cleaner is placed on its base. This reduces the requirement for a stand holder to maintain upright stability, while still preserving the cordless design's detachment convenience. The system can switch between a stable low-center-of-gravity configuration and a mobile high-center-of-gravity configuration as needed.

AI summary
Disclosed are a conversion member and an electric cleaner. The conversion member according to embodiments disclosed herein may be detachably coupled to a handle included in a main body and a pipe. Then, the main body may be connected to an intake port located at the lowest position, and the pipe may be connected to an extension handle, allowing the main body to be located at a lower position facing the intake port. Thus, the electric cleaner may have a low center of gravity. Further, when the conversion member is detached, the pipe may be located between the main body and the intake port to be connected to the main body and the intake port, respectively. Accordingly, the main body may be located at an upper position directed away from the intake port, allowing the electric cleaner to have a high center of gravity.
