Vacuum Cleaner Handle Air Outlet for Battery Cooling and Runtime
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners face challenges in efficiently cooling batteries and maximizing battery capacity to achieve longer running times and sufficient power for large air flows, particularly when integrating new battery technologies into compact designs that allow for easy storage and transport.
Innovation Solution
A two-part vacuum cleaner design with an air outlet in the handle part enables battery placement in either or both parts, ensuring cooling airflow and incorporating a duct for airflow between parts, along with a dust container air channel to minimize sealings and maintain impermeability, allowing for flexible connection via mounting or a knee joint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If batteries are placed in the handle part to increase capacity, then running time is improved, but cooling becomes difficult due to lack of airflow path
Solution Approach 1:
The vacuum cleaner is divided into two separate parts: a handle part containing the air outlet and batteries, and a base part containing the dust container. This segmentation allows the air outlet to be positioned in the handle part, creating an airflow path that passes through the batteries in the handle part for cooling, while maintaining flexible configuration options for battery placement.
2Volume of moving object
If vacuum cleaner is made in two separate parts for easy storage, then storage efficiency is improved, but airflow path between parts becomes complex
Solution Approach 1:
The air outlet in the handle part serves multiple functions: it is the primary air outlet for the vacuum cleaner and simultaneously creates a cooling airflow path for the batteries. This multi-functionality simplifies the overall airflow path design while maintaining the two-part structure for compact storage.
3Power
If more batteries are added to increase capacity, then power output is improved, but device weight increases
Solution Approach 1:
The vacuum cleaner is designed with flexible battery placement options, allowing users to configure the number and position of batteries based on their specific needs. The two-part structure enables dynamic adjustment of battery capacity while maintaining manageable weight distribution and cooling effectiveness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances battery cooling, increases battery capacity, and improves storage and transport efficiency while maintaining effective cleaning performance by allowing flexible battery placement and reducing leakage issues through a minimized sealing approach.
Implementation Method 1
the fan unit creates an air flow in a flow path extending from the air inlet via the dust separation chamber to the air outlet
Implementation Method 2
it is possible to have batteries also in this part, and still have a cooling air flow past the batteries
