Vacuum Cleaner Accessory Holder Module for Reliable Latching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing canister vacuum cleaners face issues with spring-loaded latching hooks being difficult to manufacture and function correctly, especially when the upper part is painted or coated, leading to rounded edges that affect hook functionality.
Innovation Solution
The latching hooks are arranged on a functional module that penetrates an opening in the upper part, allowing for freedom in material choice and resilient mounting, with multiple hooks securing accessories and integrated complex functions like a locking device and filter change indicator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spring-loaded latching hooks are formed directly on the upper part, then accessories can be held securely, but manufacturing becomes difficult and edges are rounded off by coating
Solution Approach 1:
The latching hooks are separated from the upper part and integrated into a separate functional module. This segmentation allows the hooks to be manufactured independently using suitable materials and methods, while the upper part can be coated without affecting the hooks. The functional module is then mounted onto the upper part, combining the benefits of both components.
2Ease of manufacture
If the upper part is painted or coated, then appearance is improved, but hook edges are rounded off and functionality deteriorates
Solution Approach 1:
The latching hooks are extracted from the upper part and relocated to the functional module. This extraction ensures that the coating process applied to the upper part does not affect the sharp edges and functionality of the hooks, as they are now part of a separate component that is not subjected to the same coating process.
3Reliability
If multiple latching hooks are provided for multiple receptacles, then all accessories can be held securely, but assembly complexity increases
Solution Approach 1:
Multiple latching hooks are merged into a single functional module, which is then mounted as one unit onto the upper part. This combining approach maintains the ability to secure multiple accessories while simplifying assembly, as the entire module with all its hooks can be installed in a single operation rather than attaching each hook separately.

AI summary
The vacuum cleaner has a housing, which has a cover-like upper part (5) for closing a dust collecting chamber and a functional module (11) directed to the dust collecting chamber. A receptacle (9) for a suction accessory is arranged on the outer side of the upper part. The hooks are arranged on the functional module.
