Solution Overview

Problem

Existing suction cleaning attachments for motor vehicles are difficult to remove from their quivers due to continuous operation requirements, leading to potential damage and high energy consumption.

Innovation Solution

A suction cleaning attachment with a stop protruding over the grip region, forming a pressure-tight seal with the quiver when inserted, allowing easy removal and reducing energy consumption by maintaining negative pressure with low energy input.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the suction cleaning attachment is continuously operated with maintained negative pressure, then the suction performance is ensured, but the removal from quiver becomes difficult and energy consumption increases

Engineering Contradiction:

Improvesuction performanceVSAvoidremoval from quiver

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The attachment is segmented into a housing portion and a grip region, with the stop feature positioned at the transition zone. This segmentation allows the stop to interact with the quver edge to facilitate removal while the housing maintains the pressure seal for suction performance.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The stop feature acts as an intermediary element between the attachment housing and the quver edge. It provides a mechanical interface that enables easy removal by interacting with the quver edge, while not interfering with the pressure seal when the attachment is inserted.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the suction cleaning attachment is continuously operated with maintained negative pressure, then the suction performance is ensured, but the energy consumption increases

Engineering Contradiction:

Improvesuction performanceVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system transitions between periodic states of operation (when attachment is removed and used) and non-operation (when attachment is inserted in quver). The stop feature enables quick transition to the non-operational state, allowing the system to consume energy only when needed, rather than continuously.

Inventive Principle:

Principle #19Periodic action

3Stability of the object's composition

If the suction cleaning attachment is difficult to remove from quiver, then the connection stability is maintained, but the user effort increases and damage risk arises

Engineering Contradiction:

Improveconnection stabilityVSAvoiduser effort

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The stop feature provides a localized interaction point at the transition zone between housing and grip region, while the rest of the housing maintains its pressure seal quality. This localized feature enables easy removal without compromising the overall connection stability when inserted.

Inventive Principle:

Principle #3Local quality
