Surface Treatment Accessory Toggle Mechanism for Multi-State Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of accessories for surface treatment apparatuses increases, it becomes difficult to store them efficiently without sacrificing functionality, as each accessory often requires separate manipulation and storage, leading to cumbersome handling and storage challenges.
Innovation Solution
Incorporating a toggle mechanism on the surface treatment apparatus that allows accessories to transition between operational states, eliminating the need for direct manipulation and enabling fewer accessories to perform multiple functions by changing their operational states through a toggle activation, rather than requiring separate handling and storage for each state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate accessories are provided for different cleaning functions, then functional versatility is improved, but storage complexity and handling difficulty increase
Solution Approach 1:
The patent combines multiple cleaning functions (brush tool, crevice tool, and extension wand) into a single integrated accessory assembly. The brush tool and crevice tool are merged into one unit that can be coupled to the vacuum cleaner, eliminating the need for separate accessories for each function.
Solution Approach 2:
The accessory assembly is designed to perform multiple functions through a single unit. The brush tool provides surface cleaning, the crevice tool provides gap cleaning, and the extension wand provides reach extension - all within one accessory that couples to the vacuum cleaner, making it a universal cleaning solution.
2Adaptability or versatility
If multiple separate accessories are provided for different cleaning functions, then functional versatility is improved, but handling ease deteriorates
Solution Approach 1:
The patent merges multiple cleaning tools into a single handleable unit. The brush tool, crevice tool, and extension wand are combined into one accessory assembly that can be easily attached and detached from the vacuum cleaner, simplifying handling compared to managing multiple separate accessories.
3Measurement precision
If accessories require direct manipulation for state changes, then operational precision is improved, but operational complexity increases
Solution Approach 1:
The accessory assembly is designed to automatically transition between operational states based on its configuration. When the extension wand is coupled to the brush tool, the crevice tool automatically extends; when the wand is removed, the crevice tool automatically retracts. This self-service mechanism eliminates the need for manual manipulation to change states.
4Device complexity
If fewer accessories are used to perform multiple functions, then storage efficiency is improved, but adaptability may deteriorate
Solution Approach 1:
The accessory assembly is designed as a universal unit that can perform multiple cleaning functions. It includes a brush tool for surface cleaning, a crevice tool for gap cleaning, and an extension wand for reaching distant areas, all integrated into one accessory that maintains full functional versatility while improving storage efficiency.
Solution Approach 2:
The accessory assembly incorporates dynamic elements that allow it to change configuration. The crevice tool can extend and retract, and the extension wand can be coupled and decoupled, enabling the single accessory to adapt to different cleaning scenarios and maintain versatility.

AI summary
A surface treatment apparatus may include a coupling, a handle, an accessory coupled to the coupling, and a toggle proximate the handle. The accessory may have at least two operational states. An actuation of the toggle may cause the accessory to transition between operational states.
