Vacuum Cleaner Telescoping Lid Assembly for Variable Canister Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing utility vacuum cleaners lack adaptability to accommodate canisters of varying sizes, leading to inefficient vacuuming and potential damage from inconsistent air pressure.
Innovation Solution
A vacuum cleaner design featuring an adjustable lid assembly that telescopes between retracted and expanded states to fit different canister sizes, coupled with a flexible gasket for airtight sealing and a suction source powered by a motor and impeller, allowing for adjustable airflow to manage debris collection effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vacuum cleaner uses a fixed-size lid assembly, then the structure is simple and manufacturing is easy, but it cannot accommodate canisters of varying sizes
Solution Approach 1:
The lid assembly incorporates telescoping members that can extend and retract to dynamically adjust the size of the lid. This allows the same lid assembly to accommodate different canister sizes by adjusting the extension state of the telescoping members, transforming a static structure into a dynamic one that adapts to varying requirements.
Solution Approach 2:
The telescoping members are designed with nested structures where one member fits inside another. When retracted, the lid assembly has a compact size for smaller canisters; when extended, it provides a larger footprint for bigger canisters. This nesting principle allows multiple size configurations within a single assembly.
2Adaptability or versatility
If the vacuum cleaner uses a rigid lid assembly, then manufacturing precision is easier to achieve, but it cannot provide flexible sealing for different canister sizes
Solution Approach 1:
The sealing system uses a flexible gasket rather than a rigid seal. This flexible gasket can deform and conform to the contours of different canister openings, ensuring a consistent air-tight seal regardless of the canister size or slight variations in canister geometry, thus maintaining seal consistency across different configurations.
Solution Approach 2:
The telescoping members allow the lid assembly to change its dimensional parameters (length, width, perimeter) to match different canister sizes. By adjusting the extension state of the telescoping members, the lid assembly modifies its geometric parameters to achieve proper alignment and sealing contact with various canister openings.
3Reliability
If the vacuum cleaner is designed for a specific canister size, then the seal is optimized for that size, but it cannot be used with other canister sizes
Solution Approach 1:
The lid assembly is designed as a universal interface that can work with multiple canister sizes through its telescoping mechanism. The combination of adjustable telescoping members and flexible gasket creates a multi-functional sealing system that maintains reliable air-tight seals across different canister dimensions, eliminating the need for multiple specialized lid assemblies.
4Adaptability or versatility
If the lid assembly is made adjustable with telescoping members, then it can accommodate various canister sizes, but the device complexity increases
Solution Approach 1:
The lid assembly is segmented into multiple telescoping members that can independently extend and retract. This segmentation allows for incremental size adjustments and provides flexibility in achieving different perimeter configurations. The segmented structure enables controlled adjustment while maintaining overall structural integrity.

AI summary
A vacuum cleaner (10) for placement atop a canister (12) including a motor housing (20) having a suction source, a handle (18) disposed adjacent the housing for maneuvering the vacuum cleaner relative to the canister, and a lid assembly (16) supporting the motor housing and configured to couple to the canister. The lid assembly is adjustable in size by moving between a retracted state and an expanded state to accommodate canisters of varying size.
