Solution Overview
Problem
Vacuum robots face challenges in safely and comfortably carrying their housing up or down stairs due to dust separation issues when the carrying handle is used, leading to potential dust leakage.
Innovation Solution
A vacuum robot design featuring a two-part closure flap for the dust collection container and an extendable carrying handle with spring elements, allowing the handle to automatically retract for space-saving and ergonomic carrying, while the closure flap ensures dust containment during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a carrying handle is used to transport the vacuum robot, then ease of carrying is improved, but dust leakage from the dust collection container occurs
Solution Approach 1:
The closure flap is divided into two separate parts: a first closure flap portion and a second closure flap portion. Each portion can independently close different openings (intake opening and discharge opening), allowing effective dust containment while maintaining structural flexibility and ease of operation during carrying.
2Object-generated harmful factors
If a continuous closure flap is used to prevent dust leakage, then dust containment is improved, but device complexity and space requirements increase
Solution Approach 1:
The closure system is segmented into two independent flap portions rather than one continuous flap. This reduces the complexity of each individual flap component and allows them to be positioned and sized more efficiently within the dust collection container structure.
Solution Approach 2:
The closure function is extracted and distributed to separate flap portions positioned at different locations (intake opening and discharge opening). This eliminates the need for a single large continuous flap, reducing overall structural complexity and space requirements.
3Volume of moving object
If the carrying handle is retracted into the housing, then space saving is improved, but ease of carrying deteriorates
Solution Approach 1:
The carrying handle is designed to be retractable into the housing structure when not in use, nesting the handle within the available space of the vacuum robot body. This minimizes the overall volume occupied by the carrying mechanism while maintaining full carrying functionality when needed.
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
Enables safe and comfortable carrying of the vacuum robot across multiple levels by preventing dust leakage and optimizing space usage, ensuring effective cleaning and maintenance without dust loss.
Implementation Method 1
at least one spring element is arranged on the carrying handle, which is designed to automatically move the carrying handle, once it has been pulled out into the carrying position against the spring force of the spring element, back into its home position by means of spring force
Implementation Method 2
a fan arranged in the housing for generating a vacuum to collect dust by means of an air stream
Implementation Method 3
a separation system for cleaning the collected air of dust
