Robot Vacuum Cleaner with Movable Grip Handle and Integrated Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous robot vacuum cleaners with hand-held units have ergonomic issues during coupling and uncoupling due to difficult handle grasping and lack of efficient locking mechanisms.
Innovation Solution
A robot vacuum cleaner design featuring a main body and a hand-held vacuum cleaner that can reversibly couple, with a grip handle that moves between retracted and deployed positions, and a single locking device that secures the handle and hand vacuum, allowing for easy handling and uncoupling with a single operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the grip handle is fixed in a deployed position for easy handling, then ease of operation is improved, but device complexity increases due to additional locking mechanisms
Solution Approach 1:
The patent combines the handle locking function with the vacuum cleaner coupling/uncoupling mechanism. The grip handle locking means are integrated into the coupling mechanism between the hand-held vacuum cleaner and main body, so that a single coupling action simultaneously secures both the vacuum cleaner unit and the handle in position, eliminating the need for separate locking devices
Solution Approach 2:
The coupling mechanism serves multiple functions: it connects the hand-held vacuum cleaner to the main body, secures the grip handle in the retracted position, and provides the structural interface for power and data transmission. This multi-functional design reduces overall system complexity while maintaining ease of operation
2Reliability
If multiple locking devices are used to secure the handle and hand vacuum, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges the handle locking function with the vacuum cleaner coupling mechanism. The grip handle locking means are integrated into the coupling mechanism between the hand-held vacuum cleaner and main body, so that a single coupling action simultaneously secures both the vacuum cleaner unit and the handle in position, eliminating the need for separate locking devices
Solution Approach 2:
The coupling mechanism is segmented into functional zones: the grip handle locking means are positioned to engage with the main body when the handle is in the retracted position, while the vacuum cleaner coupling interface engages separately. This segmentation allows each component to perform its function reliably without requiring additional locking devices
3Device complexity
If the grip handle is retracted during coupling, then device complexity is reduced, but ease of operation worsens due to difficult grasping
Solution Approach 1:
The grip handle is designed to be movable between a retracted position (during coupling) and a deployed position (during handling). The dynamic positioning allows the handle to be out of the way during coupling operations, reducing interference and simplifying the coupling mechanism, while being easily deployable when the user needs to handle the vacuum cleaner
