Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing dust containers for sweeping robots are difficult to disassemble, assemble, and clear quickly and cleanly, often resulting in user contact with dirt and potential spills during the removal process.

Innovation Solution

A dust container with a first fastening device featuring movable operating members and elastic members that allow for easy detachment and reattachment by extending or retracting fastening members into buckle slots, enabling one-handed operation for removal and reinstallation without contacting dirt.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional fastening structure is used to fix the dust container, then the dust container can be securely fixed in the dust collector, but the user must perform complex disassembly actions to remove the dust container, which increases the risk of contact with dirt and potential spills

Engineering Contradiction:

Improvesecure fixation of dust containerVSAvoidease of removal and cleaning

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The fastening device is divided into multiple independent fastening members (first and second fastening members) that can be independently operated. Each fastening member can be released separately by pressing its corresponding operating member, allowing the lid to be detached from the case in a controlled manner without requiring complex disassembly steps

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fastening members are designed to be dynamically controllable through operating members that the user can press to release. The fastening structure transitions from a static locked state to a dynamic released state, enabling easy removal of the lid from the case without complex manual manipulation

Inventive Principle:

Principle #15Dynamics

2Reliability

If the dust container is designed with a lid and case structure, then the dust can be contained effectively, but the user must open the cover to clear the dust, which increases the complexity of the cleaning process and risk of spills

Engineering Contradiction:

Improveeffective dust containmentVSAvoidcomplexity of disassembly and cleaning

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The dust container is segmented into a lid and a case that can be easily separated. The lid can be independently removed from the case through the fastening device, allowing users to access and clear dust from the case without needing to disassemble the entire container structure

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The lid is extracted as a separate removable component from the case through the fastening mechanism. This allows the lid to be taken out independently for cleaning or replacement, simplifying the overall cleaning process by separating the cover removal function from the main container structure

Inventive Principle:

Principle #2Taking out (Extraction)

3Reliability

If the fastening members extend into the buckle slots for secure attachment, then the dust container is firmly fixed, but the releasing mechanism requires complex operations that may cause dirt to fall

Engineering Contradiction:

Improvefirm attachment of dust containerVSAvoidrisk of dirt spill during removal

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The operating members are designed to be self-contained on the lid, allowing users to release the fastening members directly from the lid without needing to disassemble other components first. This self-service design enables direct control over the release process, minimizing the risk of accidental dirt spills during removal

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The fastening members are designed to release in a controlled sequence when operating members are pressed. This preliminary controlled release prevents sudden detachment that could cause dust to spill, allowing the lid to be gradually separated from the case in a controlled manner

Inventive Principle:

Principle #10Preliminary action

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Facilitates quick and clean removal of the dust container from the robot, eliminating the need for complex disassembly and reducing the risk of dirt spills, allowing users to clear the container efficiently.

Implementation Method 1

a first elastic member between the first operating members, and the first operating members each comprise a first fastening member. The first operating members have a fixing position normally butted by the first elastic member

AI summary

The dust container is disposed in the dust collector, so as to receive dirt drawn by the dust collector. The dust container includes a fastening device. The dust container can be taken out from the dust collector by operating the fastening device in one operation, and then installed back into the dust collector after the dirt is cleared away, thereby completing actions of disassembling, assembling and clearing the dust container quickly and cleanly.
