Battery and suction motor assembly for a surface treatment apparatus and a surface treatment apparatus having the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface treatment apparatuses, such as vacuum cleaners, face challenges in reducing manufacturing costs, size, and design flexibility due to separate controllers for suction motors and batteries, which also increase complexity and weight.
Innovation Solution
Integrating both suction motor and battery controllers into a single controller within the motor-battery assembly, reducing the need for additional wiring and separate components, and optimizing the placement of batteries and motors to enhance airflow and user handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate controllers for suction motors and batteries are used, then control functionality is achieved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent combines the suction motor controller and battery controller into a single integrated controller unit. This merging of previously separate control functions into one unified controller reduces device complexity and lowers manufacturing costs by eliminating the need for two separate control systems, wiring harnesses, and mounting structures.
2Device complexity
If separate controllers for suction motors and batteries are used, then control functionality is achieved, but weight increases
Solution Approach 1:
The integration of both control functions into a single controller reduces the total weight of the motor-battery assembly by eliminating redundant components, separate wiring harnesses, and multiple mounting structures that would be required if separate controllers were used.
3Ease of manufacture
If traditional motor-battery assembly design is used, then functionality is achieved, but design flexibility is limited
Solution Approach 1:
The integrated controller design simplifies the overall assembly structure by consolidating control functions into one unit, which provides greater design flexibility for the motor-battery assembly. This allows for more compact arrangements and easier integration into various surface treatment apparatus configurations.

AI summary
An example of a system, consistent with the present disclosure, may include a motor-battery assembly. The motor-battery assembly may include a housing defining one or more cavities, a suction motor configured to be fluidly coupled to a debris compartment of a vacuum cleaner for generating air flow through the vacuum cleaner for entraining debris, one or more batteries at least partially disposed within at least one of the one or more cavities, and a motor/battery controller at least partially disposed within at least one of the one or more cavities, the motor/battery controller configured to control power provided to the suction motor and to regulate charging and/or discharging of the one or more batteries.
