Support base for a handheld vacuum cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable vacuum cleaner support bases fail to compensate for vertical misalignment of wall holes, leading to an inclined storage position that can cause friction, damage, and electrical connector issues.
Innovation Solution
A support base with adjustable fixing holes and mechanisms allowing for independent adjustment in multiple directions to ensure vertical orientation, preventing inclination and ensuring secure storage and charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If oblong fixing holes are used to compensate for vertical positioning defects, then vertical positioning flexibility is improved, but vertical misalignment compensation capability deteriorates
Solution Approach 1:
The fixing holes are designed to be movable along guide grooves instead of being fixed in position. This allows the holes to dynamically adjust their location to accommodate misaligned wall holes, resolving the contradiction between positioning flexibility and alignment precision by making the system adaptable rather than static
Solution Approach 2:
The base body is divided into multiple adjustable components including movable fixing holes, guide grooves, and positioning elements. This segmentation allows independent adjustment of each component to achieve proper alignment, enabling the system to compensate for vertical misalignment while maintaining positioning flexibility
2Ease of operation
If the support base is positioned at a predetermined distance from the ground, then the suction head can rest on the ground, but the base body becomes inclined when wall holes are misaligned
Solution Approach 1:
The base body incorporates adjustable components that can dynamically reposition themselves to maintain vertical orientation. The movable fixing holes and adjustment mechanisms allow the base to adapt its position on the wall, ensuring it remains vertical even when wall holes are misaligned, thus preventing inclination while keeping the suction head at the correct height
Solution Approach 2:
The adjustment mechanisms are designed to be set before final fixation. Users can preliminarily adjust the position of fixing holes and base body orientation before tightening all fasteners, allowing proper vertical alignment to be established before the structure is locked in place
3Manufacturing precision
If adjustment mechanisms are added to compensate for misalignment, then vertical orientation is improved, but device complexity increases
Solution Approach 1:
Adjustment capabilities are localized to specific areas where misalignment occurs (the fixing hole regions) rather than requiring global adjustment mechanisms throughout the entire base body. This concentrates the complexity only where needed, maintaining simplicity in other parts of the structure

AI summary
The support base (3) comprises a base body (33); a first fixing hole (34) provided on the base body (33) and configured to be passed through by a first fixing screw, so as to fix the base body (33) to a first fixing point - a second fixing hole (35) provided on the base body (33) and configured to be passed through by a second fixing screw, so as to fix the base body (33) to a second fixing point - a support device configured to support a handheld vacuum cleaner (2); and first adjustment means configured to adjust a positioning of the base body (33) relative to the first fixing point along a first adjustment direction (D1) and a second adjustment direction (D2) which are different from each other.
