Vacuum Cleaner Stabilizer Linkage for Dynamic Tip-Over Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surface treatment apparatuses, such as vacuum cleaners, lack stability when not in use, which can lead to tipping over and potential damage or injury, and existing solutions do not effectively balance stability with maneuverability during cleaning operations.
Innovation Solution
Incorporating stabilizers that transition between extended and retracted positions in response to the upright section's position change, improving stability without interfering with the cleaning process by retracting when the apparatus is in use and extending when stored.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If stabilizers are extended to improve stability when not in use, then stability is improved, but maneuverability during cleaning operations deteriorates
Solution Approach 1:
The stabilizer is designed to dynamically change its position between extended and retracted states based on the operational mode. When the upright section is in the storage position, the stabilizer extends to provide stability. When the upright section is in the in-use position, the stabilizer retracts to allow maneuverability. This dynamic adaptation resolves the contradiction by making the stabilizer's presence conditional on the operational state.
Solution Approach 2:
The stabilizer system is configured to automatically transition between extended and retracted positions in response to the upright section's position changes without requiring manual intervention. The system self-adjusts based on whether the apparatus is being used or stored, eliminating the need for user action to deploy or retract the stabilizer.
2Stability of the object's composition
If stabilizers are always extended to prevent tipping, then stability is improved, but the cleaning process is interfered with
Solution Approach 1:
The stabilizer transitions from a static always-extended design to a dynamic system that extends only when needed (during storage) and retracts during cleaning operations. This dynamic behavior ensures stability when the apparatus is not in use while eliminating interference with the cleaning process when it is in use.
Solution Approach 2:
The stabilizer automatically responds to the operational state of the apparatus, extending when stored and retracting when in use, without requiring manual control. This self-service mechanism ensures that the stabilizer does not interfere with cleaning operations while maintaining stability during storage.
3Reliability
If stabilizers are added to improve stability, then reliability is improved, but device complexity increases
Solution Approach 1:
The stabilizer is integrated with the existing structure of the surface treatment apparatus, specifically combining with the upright section and main body. The stabilizer shares structural elements and mounting points with the existing framework, adding the stability function without requiring a completely separate structural system.
Solution Approach 2:
The stabilizer serves multiple functions: it provides stability during storage, automatically deploys based on the operational state, and integrates with the existing structural framework. This multi-functionality reduces the need for additional separate components to achieve stability.

AI summary
An example of a surface cleaning head may include a main body, a neck pivotally coupled to the main body, a stabilizer, and a linkage pivotally coupled to the main body and the stabilizer. The linkage may be configured to cause the stabilizer to transition between an extended position and a retracted position in response to a pivotal movement of the neck.
