Transparent Vacuum Cleaning Head With Ribbed Airflow Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface cleaning heads lack transparency in airflow passages, making it difficult for users to detect blockages and suffer from rigidity issues due to inadequate reinforcement, affecting vacuum cleaner efficiency.
Innovation Solution
A surface cleaning head with a clam shell construction featuring a transparent front portion made of a single layer of plastic, reinforced with ribs for rigidity, and an open-sided airflow chamber that allows users to view the air channel for blockage detection, combined with front wheels positioned under the lower section for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If the front portion is made transparent to enable blockage detection, then visibility of airflow passage is improved, but structural rigidity deteriorates
Solution Approach 1:
The patent employs a thin transparent front portion made of a single layer of plastic with thickness less than 0.1 inch. This thin film structure provides the necessary transparency for blockage detection while inherently limiting structural rigidity, which is then compensated by reinforcing ribs.
Solution Approach 2:
The patent adds reinforcing ribs to the thin transparent front portion, transitioning from a two-dimensional thin film to a three-dimensional reinforced structure. This dimensional addition provides the necessary rigidity support while preserving the transparency function for blockage detection.
2Ease of manufacture
If the front portion is made from a single layer of thin plastic for simplicity, then manufacturing ease is improved, but structural durability deteriorates
Solution Approach 1:
The front portion is constructed from a single layer of plastic with thickness less than 0.1 inch, which simplifies the manufacturing process compared to multi-layer constructions. This thin film approach maintains ease of manufacture while the added reinforcing ribs compensate for the reduced inherent durability.
Solution Approach 2:
By adding reinforcing ribs to the single-layer thin plastic structure, the patent enhances structural durability without complicating the basic single-layer construction approach, thus maintaining manufacturing simplicity while improving reliability.
3Quantity of substance
If the front portion is made transparent with thin plastic, then material usage is reduced, but resistance to deflection during use deteriorates
Solution Approach 1:
The patent uses a single layer of plastic with thickness less than 0.1 inch for the front portion, which significantly reduces material usage compared to thicker or multi-layer constructions. This minimal material usage is sufficient for transparency and basic structure, with deflection resistance enhanced by reinforcing ribs.
Solution Approach 2:
The reinforcing ribs add a third-dimensional structural element to the thin two-dimensional plastic layer, providing resistance to deflection during use without requiring increased material thickness or quantity, thus maintaining low material usage while improving mechanical performance.
