Vacuum Cleaner Drawer Mechanism for Integrated Accessory Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners face difficulties in user-friendly and safe operation due to cumbersome handling of accessories, which are often stored separately and require complex methods for access.
Innovation Solution
A vacuum cleaner with a drawer element and a method for opening and closing it, featuring a coordinated geometry between the holding and locking elements, a drive element with a spring for constant movement, and a telescopic rail arrangement for linear guidance, allowing for easy access and storage of accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If accessories are stored separately from the vacuum cleaner, then the vacuum cleaner structure is simpler, but handling and access to accessories becomes difficult and cumbersome
Solution Approach 1:
The patent combines the accessory storage function with the vacuum cleaner body by integrating a drawer element into the housing. This merging allows accessories to be stored within the vacuum cleaner structure itself, eliminating the need for separate storage while maintaining easy access through the drawer mechanism.
2Ease of operation
If accessories are integrated into the vacuum cleaner housing, then accessory access is improved, but the device complexity increases
Solution Approach 1:
The patent segments the vacuum cleaner housing into functional zones including a drawer element for accessory storage, a working zone for vacuum operations, and a storage zone. This segmentation organizes components logically, improving accessibility while maintaining overall structural coherence and manageable complexity.
Solution Approach 2:
The drawer element is designed as a dynamic component that can move between closed and open positions along a guided path. This dynamic design allows easy access to accessories when needed while maintaining a compact integrated structure during normal operation, balancing accessibility with structural efficiency.
3Speed
If the drawer element moves quickly, then operation speed is improved, but control and safety during operation deteriorates
Solution Approach 1:
The patent introduces a drive element as an intermediary mechanism between the user's opening action and the drawer element. This drive element provides controlled movement along a defined path, ensuring safe and manageable operation speeds while maintaining smooth drawer movement. The drive element acts as a mediator that translates user input into controlled drawer motion.
4Ease of operation
If the drawer element is easily accessible, then user convenience is improved, but the risk of unintended operation increases
Solution Approach 1:
The patent implements a locking element that must be actively released before the drawer element can move. This preliminary locking action prevents unintended opening while maintaining easy access through the simple release mechanism. The locking element ensures the drawer remains secure during transport and operation, requiring deliberate user action to open.
