Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface cleaners lack efficient and intuitive methods for transitioning between different cleaning modes and accessories, leading to complications in fluid connection, hose kinking, and user experience.
Innovation Solution
A surface cleaner design featuring a pivotally coupled base with a suction inlet port accessible for both nozzle and accessory connections, allowing for a direct and parallel fluid path, reducing hose kinking and enhancing user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed nozzle connection is used at the suction inlet port, then the fluid connection is sealed and reliable, but the accessibility of the suction inlet port is reduced and accessory switching becomes complicated
Solution Approach 1:
The nozzle is designed with a removable coupling mechanism that allows it to be easily attached and detached from the suction inlet port. This dynamic connection system enables the nozzle to transition between fixed (when attached) and accessible (when removed) states, resolving the contradiction between connection reliability and accessory switching ease
2Ease of operation
If the suction inlet port is always accessible, then accessory switching is easy and intuitive, but the fluid connection reliability and sealing are compromised
Solution Approach 1:
The coupling mechanism provides a dynamic state system where the suction inlet port transitions between being covered (when nozzle is attached) and accessible (when nozzle is removed). This allows the port to maintain reliability when needed while enabling easy accessory switching when required
3Device complexity
If a non-parallel fluid path is used, then the housing structure is simpler, but hose kinking occurs and fluid flow efficiency is reduced
Solution Approach 1:
The fluid path is designed to extend parallel to the cleaning surface (horizontal dimension) rather than vertically upward, creating a direct route from the suction inlet port to the recovery tank. This dimensional change in the fluid path routing eliminates hose kinking and improves flow efficiency while maintaining housing structure simplicity
