Dust Collection Unit Handle Layout for One-Handed Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners with dust collection units are inconvenient to handle, separate, and clean due to the need to hold the dust collection box handle with one hand and operate a hanging structure with the other, leading to difficulties in removing the upper cover without detaching dirt and interference between components.
Innovation Solution
A vacuum cleaner design featuring a dust collection unit with a handle having an open bottom for easy grip and a detachable lever for separation, along with finger grooves on the upper cover for convenient handling and reduced interference during separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a dust collection box handle extending in a vertical direction is formed at a side surface of the dust collection box, then the dust collection unit can be held and separated from the main body, but the user has to hold the handle with the body down and operate the hanging structure with the other hand, reducing convenience
Solution Approach 1:
The patent combines the dust collection box handle with the hanging structure operation mechanism. The handle is positioned and designed such that a single hand can simultaneously grip the handle and manipulate the hanging structure to separate the dust collection unit from the main body, merging two previously separate operations into one unified action.
Solution Approach 2:
The handle is repositioned from a vertical orientation at the side surface to an extended orientation at the front end of the dust collection box. This spatial reconfiguration allows the user's hand to naturally access both the grip and the hanging structure mechanism in a single ergonomic position, eliminating the need for body tilting and two-handed operation.
2Ease of operation
If the upper cover is pulled out by holding a cover handle using one hand, then the cover can be separated, but the cover leans toward one direction causing dirt to detach from the filtering member
Solution Approach 1:
The upper cover separation mechanism transitions from a single-point handle pull to a two-point finger groove grip system. The finger grooves are positioned on opposite sides of the upper cover, enabling the user to apply balanced upward forces from both hands, preventing lateral leaning and ensuring vertical, stable separation that keeps dirt securely attached to the filtering member.
Solution Approach 2:
The finger grooves are pre-positioned on the upper cover at optimal locations that guide the user's fingers to apply force at the correct points. This preliminary design of the grip interface ensures that when the user pulls the cover, the force is automatically distributed evenly, preventing unwanted lateral movement before it can occur.
3Ease of operation
If the upper cover is pulled out without proper guidance, then the cover can be separated, but interference between the upper cover and dust collection box occurs, making separation difficult
Solution Approach 1:
The finger grooves act as intermediary elements that mediate between the user's hands and the upper cover. These grooves provide a controlled interface that guides the separation force, preventing direct contact between the user's fingers and the cover surface that could cause misalignment. The grooves ensure the cover moves along the correct separation path without interfering with the dust collection box.
Solution Approach 2:
The separation mechanism uses two-point contact through finger grooves instead of single-point handle pulling. This dimensional change in the force application interface provides stability and guidance, preventing the cover from tilting or snagging on the dust collection box during separation, thereby eliminating interference issues.
