Spherical Canister Cleaner Structure for Self-Balancing Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Canister type vacuum cleaners face difficulties in maintaining balance and moving performance due to the main body losing track direction or overturning when encountering obstacles during cleaning.
Innovation Solution
The design includes a spherical first main body with a protruding second main body that stabilizes the cleaner, a central moving wheel, and auxiliary wheels for improved balance and movement, along with a direction switching unit for directional changes, enhancing the cleaner's ability to self-balance and navigate obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cleaner main body is designed with a traditional structure, then it is simple to manufacture, but it loses track direction or overturns when encountering obstacles
Solution Approach 1:
The cleaner main body is designed with a spherical shape instead of a traditional rectangular structure. This spherical design allows the cleaner to automatically return to an upright position after tilting or overturning by rolling back, and enables it to navigate around obstacles smoothly without getting stuck or losing directional control.
2Reliability
If the cleaner main body is made larger to improve stability, then balance is improved, but internal space utilization decreases
Solution Approach 1:
The spherical shape of the cleaner main body provides inherent stability through its geometry, allowing it to self-correct when tilted or overturned. The spherical design maintains a compact external volume while maximizing internal space utilization, as the rounded shape efficiently accommodates internal components without requiring excessive overall dimensions.
3Reliability
If the cleaner main body is designed with curved surfaces, then it can return to original position after tilting, but manufacturing precision requirements increase
Solution Approach 1:
The cleaner main body is designed with a spherical shape that enables automatic return to upright position through rolling motion. The spherical geometry provides consistent curvature that facilitates self-balancing while being manufacturable using standard spherical forming processes, balancing the need for precision with manufacturing feasibility.

AI summary
A cleaner comprises a cleaner main body, a first main body formed in a spherical shape and a second main body protruding from the front of the first main body such that the width at a second point located forward of a first point is smaller than the width at the first point.
