Vacuum Cleaner Equipped With A User Interface With Improved Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of dedicated seals for each control button in vacuum cleaners complicates the structure and increases manufacturing costs, making the assembly process more complex.
Innovation Solution
A vacuum cleaner design featuring a user interface with a stationary support part and a peripheral seal extending around its perimeter, allowing a single sealing on an immobile piece, which is easier to produce and assemble, using materials like elastomer or flexible polyvinyl chloride for the seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated seals are produced for each control button, then sealing reliability is improved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent merges multiple sealing functions into a single peripheral seal that surrounds the entire control part. Instead of having separate seals for each control button, one continuous seal integrates the sealing function across all button interfaces, reducing the number of sealing components from multiple individual seals to a single unified seal structure.
Solution Approach 2:
The peripheral seal serves multiple sealing functions simultaneously - it seals around all control buttons (On/Off button, activation button) and protects against liquid penetration and dust evacuation at all button interfaces. This single seal structure performs the work of multiple dedicated seals, providing universal sealing protection for the entire user interface.
