Solution Overview

Problem

Existing cleaning devices, especially large and heavy ones, oscillate or tip over during above-floor cleaning, making them difficult to guide stably and safely.

Innovation Solution

A detachable handle is arranged on the accessory connection of the cleaning device, with a handle base clamped between the accessory connection and the connection piece, providing additional stability and preventing pendulum movements by allowing the user to grasp the handle instead of the housing directly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a handle is added to the cleaning device for above-floor cleaning, then the stability and ease of guidance is improved, but the device complexity increases

Engineering Contradiction:
Improveease of guidanceVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The handle is designed to be detachably arranged on the accessory connection, allowing it to be attached when needed for above-floor cleaning and removed when not needed. This dynamic configuration allows the device to adapt its structure based on the cleaning task, providing ease of guidance only when required while maintaining simplicity for other operations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The handle is integrated with the existing accessory connection system, which is already a universal interface for attaching various cleaning accessories. By placing the handle base on the accessory connection, the same connection point serves dual purposes: attaching cleaning accessories and providing a mounting point for the handle, thereby avoiding additional complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Stability of the object's composition

If the handle base is clamped between the accessory connection and connection piece, then the stability during above-floor cleaning is improved, but the manufacturing precision requirements increase

Engineering Contradiction:
ImprovestabilityVSAvoidmanufacturing precision
Core Design Contradiction:
Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

The handle base is designed with specific dimensional parameters (length, width, thickness) that allow it to be clamped between the accessory connection and connection piece. By carefully selecting these parameters, the handle base creates a stable sandwich structure without requiring extremely tight tolerances, as the clamping action itself provides the necessary stability.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The handle base acts as an intermediary element between the accessory connection and the connection piece. This intermediate component distributes the clamping forces and provides a stable mounting point for the handle, reducing the precision requirements for the direct interface between the accessory connection and connection piece.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the handle is detachably arranged on the accessory connection, then the adaptability for different cleaning scenarios is improved, but the reliability of the connection may worsen

Engineering Contradiction:
ImproveadaptabilityVSAvoidconnection reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The handle is designed to be detachably arranged on the accessory connection, allowing it to be attached when needed for above-floor cleaning and removed when not needed. This dynamic configuration allows the device to adapt its structure based on the cleaning task, providing ease of guidance only when required while maintaining simplicity for other operations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The handle attachment mechanism is merged with the existing accessory connection system. The handle base uses the same connection interface as cleaning accessories, combining the functions of accessory attachment and handle mounting into a single reliable connection mechanism, thereby maintaining connection reliability while achieving adaptability.

Inventive Principle:
Principle #5Merging (Combining)
