Handheld Vacuum Dust Container Cover for Hidden Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In handheld vacuum cleaners, the power supply wires are visible through the transparent or translucent dust container, which is aesthetically unpleasing and may cause functional issues such as the main body being pushed down when the handle terminal is coupled to the main body terminal.
Innovation Solution
A cover member is introduced to conceal the wires between the main body and the handle unit, ensuring they are not visible from the outside of the dust container, and the handle terminal is mechanically coupled to the main body terminal to prevent the main body from being pushed down during connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the dust container is made transparent or translucent to allow visual checking of dust, then the aesthetic appearance and user convenience are improved, but the wires become visible through the container which is aesthetically unpleasing
Solution Approach 1:
A cover member is introduced as an intermediary component between the transparent dust container and the wires. This cover member selectively blocks the visibility of wires through the container while maintaining the transparency of the container itself, thus resolving the contradiction between aesthetic appearance and wire visibility.
2Reliability
If the handle terminal is coupled to the main body terminal to establish electrical connection, then the power supply function is improved, but the main body may be pushed down during connection which causes misassembly
Solution Approach 1:
The cover member is designed with preliminary anti-action features that prevent the main body from being pushed down during terminal coupling. By providing structural support and guidance in advance, the cover member prevents misassembly before it can occur, ensuring both reliable electrical connection and assembly stability.
Solution Approach 2:
The cover member acts as an intermediary structure between the handle terminal and main body terminal during the coupling process. It provides mechanical guidance and support, preventing direct downward force on the main body while enabling proper terminal alignment and connection.

AI summary
A cleaner includes: a suction unit that guides air and dust; a main body connected with the suction unit and including a dust separation unit that separates dust from air, and a dust container that stores dust separated by the dust separation unit, at least a portion of the dust container being transparent or translucent; a handle unit connected to the main body and has a battery; a power receiving component disposed in the main body to be supplied with power from the battery; wires that are connected to the power receiver; and a cover member coupled to the main body and disposed between the main body and the wires to prevent the wires from being seen from the outside of the dust container.
