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

VSEngineering 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

Engineering Contradiction:
Improvevertical positioning flexibilityVSAvoidvertical misalignment compensation
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

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

Inventive Principle:
Principle #15Dynamics

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

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improvesuction head positioningVSAvoidbase body vertical orientation
Core Design Contradiction:
Ease of operationVSStability of the object's composition

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

Inventive Principle:
Principle #15Dynamics

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

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If adjustment mechanisms are added to compensate for misalignment, then vertical orientation is improved, but device complexity increases

Engineering Contradiction:
Improvevertical orientation accuracyVSAvoidstructure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

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

Inventive Principle:
Principle #3Local quality
