Solution Overview

Problem

Conventional dust collectors for vacuum cleaners face issues with the handle or grip piece rotating unnecessarily in a locking released state, leading to inconvenience and potential leakage of collected impurities or water, causing secondary contamination.

Innovation Solution

A dust collector with a handle unit featuring a rotating coupling member and a handle coupling member that includes fixing protrusions and a latch piece to securely lock the centrifugal separating tube to the dust box, preventing unwanted rotation and leakage by using elastic members to automatically return to a fixing or release position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the handle or grip piece is designed to be rotatable for coupling/separation operation, then the ease of operation is improved, but the handle may rotate unnecessarily in a locking released state causing instability and potential leakage

Engineering Contradiction:
Improveease of coupling/separationVSAvoidstability of handle position
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The handle is designed to be dynamically adjustable between locked and unlocked states. During coupling/separation, the handle can rotate freely to engage or disengage the locking mechanism. Once locked, the handle固定在特定位置防止不必要的旋转。这种动态设计使手柄在操作时灵活,在锁定时稳定。

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The elastic member provides tactile feedback and automatic positioning. When the handle is rotated to the correct position, the elastic member engages with the positioning structure, providing a click sensation that confirms proper engagement. This feedback mechanism ensures the handle is reliably positioned without requiring user judgment, preventing unintended rotation while maintaining ease of operation.

Inventive Principle:
Principle #23Feedback

2Reliability

If the locking mechanism is designed to firmly keep components coupled, then the reliability is improved, but the complexity of the device increases

Engineering Contradiction:
Improvefirm coupling of componentsVSAvoidcomplexity of locking mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking mechanism is segmented into distinct functional components: the handle for user operation, the elastic member for providing locking force, the positioning structure for ensuring correct alignment, and the coupling interface for connecting components. This segmentation allows each component to perform its specific function efficiently, achieving reliable coupling without requiring a complex integrated mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The elastic member automatically provides the necessary locking force once the handle is positioned correctly. The mechanism self-regulates through the elastic deformation and recovery of the elastic member, which automatically adjusts to maintain firm coupling. This self-service characteristic reduces the need for additional control mechanisms, simplifying the overall design while ensuring reliable coupling.

Inventive Principle:
Principle #25Self-service
