Upright Vacuum Cleaner Holding Assembly for Stable Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Upright type vacuum cleaners face issues with the body rotating and falling during storage due to its rotatability, necessitating a mechanism to maintain a fixed angle with the cleaning surface.
Innovation Solution
Incorporation of a supporting assembly with a holding unit that limits rotation and a supporting unit to maintain the body at a predetermined tilted angle, allowing for convenient cleaning and easy storage by preventing the body from rotating and ensuring it remains upright during storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the body is made rotatable with respect to the objective surface to enable angle adjustment during cleaning, then the ease of operation is improved, but the stability during storage deteriorates as the body may rotate and fall down
Solution Approach 1:
The holding unit is designed to automatically engage and lock the body at a predetermined angle before storage occurs. This preliminary locking action prevents the body from rotating or falling during storage, while still allowing users to adjust the angle during cleaning operations.
Solution Approach 2:
The holding unit acts as an intermediary mechanism between the rotatable body and the base. It mediates the rotation movement by allowing controlled adjustment during use while preventing uncontrolled rotation during storage, thus resolving the contradiction between operability and stability.
2Stability of the object's composition
If the body is kept at a fixed angle to prevent rotation during storage, then the stability during storage is improved, but the ease of operation deteriorates as angle adjustment becomes difficult
Solution Approach 1:
The system dynamically switches between two states: during cleaning, the body can be adjusted to various angles for operational flexibility; during storage, the holding unit engages to maintain a fixed predetermined angle for stability. This dynamic behavior resolves the contradiction between fixed stability and adjustable operability.
Solution Approach 2:
The holding unit is designed to automatically engage and disengage based on the operational state. When the cleaner is placed upright for storage, the holding unit self-activates to lock the body at the predetermined angle, eliminating the need for manual intervention and ensuring stability without compromising ease of operation during cleaning.
3Stability of the object's composition
If a supporting structure is added to maintain fixed angle during storage, then the stability during storage is improved, but the device complexity increases
Solution Approach 1:
The holding unit is merged with the existing rotatable joint structure of the cleaner. By integrating the locking mechanism into the already-present rotational interface, the design achieves storage stability without adding a completely separate supporting structure, thus minimizing the increase in device complexity.
Solution Approach 2:
The holding unit employs simple, inexpensive mechanical components such as spring-loaded latches or cam mechanisms that can be easily manufactured and integrated. These simple components provide effective angle locking without requiring complex electronic or mechanical systems, thereby limiting the increase in device complexity.
