Suction assembly comprising a support base and a portable vacuum cleaner provided with holding members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable vacuum cleaners often experience a decrease in clamping force over time when stored on a support base without being connected to a surface, leading to potential slipping and falling.
Innovation Solution
Incorporating a gripping handle with lateral holding members and a support base with retaining tabs that engage under these members to prevent vertical sliding and ensure stable storage, even when not connected to a surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If retaining devices are used to clamp the gripping handle on the support base, then the handheld vacuum cleaner can be stored in a fixed position, but the clamping force decreases over time causing the vacuum cleaner to slip and fall
Solution Approach 1:
The solution introduces a new dimensional constraint by adding retaining members that extend laterally from the gripping handle. These members engage with retaining elements on the support base, creating a multi-dimensional retention system that prevents vertical sliding in addition to horizontal clamping, thereby maintaining storage stability without relying solely on decreasing clamping force
Solution Approach 2:
The retention system is segmented into multiple independent components: retaining members on the handle and retaining elements on the base. This segmentation allows each component to perform a specific retention function, distributing the retention load and preventing single-point failure that would occur with a simple clamping mechanism
2Adaptability or versatility
If the handheld vacuum cleaner is stored without being connected to a suction tube, then it can be freely placed on the support base, but the retaining devices cannot maintain optimal tightening
Solution Approach 1:
The retention system is designed to be universal, functioning effectively whether the vacuum cleaner is connected to a suction tube or stored independently. The retaining members and elements create a retention mechanism that adapts to different storage scenarios, maintaining reliability in both connected and disconnected states without requiring additional components
