Stick Vacuum Support Body Grip for Stable Leaning Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum cleaners with a detachable nozzle and wheels are difficult to temporarily set aside without slipping or tipping, making them hard to manage during breaks or when needing to free hands, potentially causing damage or knocking over objects.
Innovation Solution
A stick-formed vacuum cleaner with a friction-increasing and slip-reducing layer on the upper portion of the support body, allowing it to be leaned against objects without sliding or tipping, featuring an elongated strip with a surface structure like shark fins or saw teeth and a part-spherical bump for enhanced grip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the nozzle device is provided with wheels to facilitate movement, then ease of operation is improved, but stability when set aside deteriorates
Solution Approach 1:
The support body is divided into functional segments: the upper portion maintains smooth surfaces for gripping and maneuvering, while the lower portion incorporates a friction-increasing layer specifically for stable placement. This segmentation allows different parts of the same object to have contrasting surface properties optimized for their specific functions.
Solution Approach 2:
The friction-increasing layer is applied locally to the lower portion of the support body rather than the entire surface. This local modification provides enhanced grip and stability when the vacuum cleaner is leaned against surfaces, while leaving the upper portions smooth for easy gripping and movement during operation.
2Stability of the object's composition
If the support body is made heavier to improve stability, then stability when set aside is improved, but ease of operation deteriorates
Solution Approach 1:
Instead of changing the weight parameter of the entire support body, the invention changes the surface friction parameter locally at the lower portion. The friction-increasing layer modifies the interaction between the vacuum cleaner and supporting surfaces, providing stability without altering the overall mass or requiring additional weight.
3Stability of the object's composition
If a stand is provided for storing and charging, then stability when not in use is improved, but device complexity increases
Solution Approach 1:
The vacuum cleaner's own lower portion is modified with a friction-increasing layer, allowing it to serve its own stability needs. This self-service approach eliminates the requirement for external stands or supporting structures, reducing overall system complexity while maintaining stability when the device is not in use.
Solution Approach 2:
The lower portion of the support body serves multiple functions: it provides structural support during operation, enables stable placement when set aside, and facilitates leaning against surfaces. By integrating these functions into the existing structure rather than adding separate components, the invention avoids increasing device complexity.
