Canister Vacuum Steering Joint for Stable Obstacle Maneuvering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional canister vacuum cleaners face difficulties in maneuverability and stability, particularly when navigating around obstacles and changing direction, due to the fixed orientation of the separating apparatus and rolling assembly, which can lead to instability and potential entrapment against upstanding items.
Innovation Solution
The introduction of a steering mechanism that allows relative pivotal movement between the separating apparatus and the rolling assembly, combined with a substantially spherical rolling assembly and inclined rotational axes of the rolling elements, enhances maneuverability and stability by adjusting the center of gravity and enabling rapid direction changes, while maintaining a fluid-tight seal through a ball and socket joint connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed orientation separating apparatus and rolling assembly are used, then the structure is simple, but the maneuverability and stability deteriorate when navigating around obstacles and changing direction
Solution Approach 1:
The patent applies the dynamics principle by making the separating apparatus pivotable relative to the rolling assembly through a steering mechanism. This allows the separating apparatus to dynamically adjust its orientation in response to steering inputs, improving maneuverability when navigating around obstacles and changing direction, while maintaining a relatively simple overall structure.
2Stability of the object's composition
If a fixed orientation separating apparatus and rolling assembly are used, then the manufacturing is simple, but the stability deteriorates when changing direction
Solution Approach 1:
The steering mechanism enables the separating apparatus to pivot dynamically, allowing the center of gravity to shift toward the steering direction during direction changes. This dynamic adjustment maintains stability during maneuvering while keeping the structural complexity relatively low.
3Reliability
If a fixed orientation separating apparatus and rolling assembly are used, then the device is simple, but the risk of entrapment against upstanding items increases
Solution Approach 1:
The pivotable separating apparatus can dynamically adjust its orientation to follow the steering direction, reducing the likelihood of the appliance becoming trapped against upstanding items such as furniture or obstacles. This improves reliability by preventing entrapment while maintaining a relatively simple structural design.
