Hand-held vacuum cleaner with grip handle accommodating battery interconnect board
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of cable paths and connectors within the handle of portable vacuum cleaners increases manufacturing costs and complicates assembly, while also affecting ergonomics and reliability.
Innovation Solution
A configuration where the rechargeable battery is housed partly in the grip handle, with a battery interconnection board that reduces intermediate cable paths and connectors, allowing for a simpler assembly and lower manufacturing costs, while enhancing ergonomics and reliability through a direct electrical connection and balanced mass distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If numerous cable paths and intermediate connectors are provided within the grip handle to ensure electrical connection between the rechargeable battery and the suction motor, then reliable electrical connection is achieved, but the assembly becomes complicated and manufacturing costs significantly increase
Solution Approach 1:
The patent extracts the battery interconnection board from the main body and relocates it to the grip handle, positioning it as close as possible to the battery. This extraction eliminates the need for long cable paths and multiple intermediate connectors, reducing assembly complexity while maintaining electrical connection reliability through direct connection.
Solution Approach 2:
The patent repositions the battery interconnection board into a different spatial dimension (the grip handle) rather than keeping it in the main body. This dimensional relocation shortens the electrical connection path and reduces the number of intermediate connectors needed, thereby simplifying assembly while preserving connection reliability.
2Reliability
If numerous cable paths and intermediate connectors are provided within the grip handle to ensure electrical connection, then electrical connection is established, but manufacturing costs significantly increase
Solution Approach 1:
By extracting the battery interconnection board from the main body and placing it in the grip handle, the patent eliminates the need for complex cable routing and multiple connectors. This reduction in component count directly lowers manufacturing costs while maintaining reliable electrical connection between the battery and motor.
3Device complexity
If the battery interconnection board is positioned as close as possible to the grip handle and rechargeable battery, then intermediate cable paths and connectors are reduced, but the structural arrangement becomes more constrained
Solution Approach 1:
The patent segments the vacuum cleaner into distinct functional modules (main body, grip handle, battery compartment) with the battery interconnection board integrated into the grip handle. This segmentation allows each module to be independently designed and assembled, reducing cable path complexity while maintaining structural arrangement flexibility through modular design.

AI summary
The handheld vacuum cleaner comprises a main body (4); a suction motor (14); a handle (6); and a rechargeable battery (18). The handle (6) has a first handle portion (22) that is integral with the main body (4). The rechargeable battery (18) is housed at least partially within the first handle portion (22) and is removably attached to the first handle portion (22). The handheld vacuum cleaner (2) includes a battery interconnect board (33) that is disposed within the first handle portion (22) and is configured to be electrically connected to the rechargeable battery (18) when the rechargeable battery (18) is attached to the first handle portion (22).
